Title: Why do astronauts on board ISS float around
Post by: Yendor on December 16, 2015, 01:05:18 PM
When I was growing up it was centrifugal force that caused objects to move outwards. Like centrifugal clutches and the weights in a distributor would move outwards to advance the timing. Then I started reading that centrifugal force was not a real force at all it was really centripetal force. So, I thought I'd study this a little deeper. That is when I got on the subject of satellites in orbit. I read the following:

Velocity, Acceleration and Force Vectors
The motion of an orbiting satellite can be described by the same motion characteristics as any object in circular motion. The velocity of the satellite would be directed tangent to the circle at every point along its path. The acceleration of the satellite would be directed towards the center of the circle - towards the central body that it is orbiting. And this acceleration is caused by a net force that is directed inwards in the same direction as the acceleration. This centripetal force is supplied by gravity - the force that universally acts at a distance between any two objects that have mass. Were it not for this force, the satellite in motion would continue in motion at the same speed and in the same direction. It would follow its inertial, straight-line path. Like any projectile, gravity alone influences the satellite's trajectory such that it always falls below its straight-line, inertial path. They demonstrated this with the following image:
(http://i.imgur.com/dlM1536.jpg)

This picture shows an object following a path around the Earth at a precise distance above the Earth because inertia is causing the object to fly straight and gravity wants to pull the object down to Earth. What you have is a nice curve flight around the Earth. Well, if this is the case, then isn't this the same thing airplanes do. They fly around the Earth everyday. The airplane's engine is providing the inertia to cause the airplane to fly forward and gravity is trying to pull the airplane down. The pilot has to maintain altitude and direction and a nice curved path is maintained around the Earth just like a satellite does. It is really a balancing act between gravity and inertia. Gravity is trying to pull it down, but inertia keeps it from happening. If the airplane's engine stops, gravity will take over and it will free fall to the ground. If the satellite's inertia runs out, then the satellite will free fall to the ground. In this case, the only real difference between a satellite and an airplane is how high each fly. What I don't understand is why do all the videos show the astronauts floating around inside the ISS. To me that is no more possible than passengers on an airplane floating around inside the airplane. We all know that doesn't happen. Some say it is because the ISS is in free fall and it is like being on an free falling elevator. That can't be true because inertia is what keeps satellites and airplanes from free falling to the ground in the first place. Others say they float around because there is no gravity in space. That is not true, there is only 10% less gravity on the ISS then on Earth and that is not enough difference to keep passengers on an airplane from floating around. So, I sit here and wonder if the videos of the ISS true, false or I'm I totally off base on my reasoning?

Very interesting question, Yendor.

Much like, "why do people walking on the moon appear to be moving in slow motion?"

In reduced gravity, it is reasonable to think that they would actually move faster. But that's not what the "footage" shows. Maybe a believer can educate us?

This picture shows an object following a path around the Earth at a precise distance above the Earth because inertia is causing the object to fly straight and gravity wants to pull the object down to Earth. What you have is a nice curve flight around the Earth.

This depiction of "reality" is impossible.

Any drawing showing a circular orbit of an object around the Earth is bogus. Geostationary satellites are not only physically but also conceptually impossible.

In the vicinity of the Earth 3 main gravitational forces play a role (excluding the effects of our neighbors Mars and Venus, giant planets farther away and effects of the Milky Way).

Any object in space around the Earth must be susceptible (and thus the orbit of such an object is defined by that) to the gravitational fields/forces of:
- Earth
- Moon
- Sun

We know that the Earth and Moon are in an eternal tidal orbital dance with each other; the gravitational pull of the Earth at least works to the Moon (~380,000 km) and the center of gravity of this combined system is skewed. Even if a "geostationary" satellite were possible, it would orbit around that "point" (it's a path as Moon and Earth move in 3D) rather than around Earth.

Reciprocally our grand small sister gives us the effects of spring tides; it is able to lift half the water mass on the planet by meters and push it down by the same "pulling effect" (no physical term) on the antipodal side of Earth.

Then we have a huge Sun which is acting on this whole system as well.

To paint a circular orbit around Earth like the Earth-Moon gravitational field and the gravitational effects of the Sun do not exist is ridiculous science fiction showing a lack of understanding of the dynamic forces of space.

Inertia is not what keeps airplanes from falling.  Lift opposes gravity for an airplane.  And the difference between airplanes and satellites is not how high they fly, it is the speed.

You might move faster if the only difference was you had less weight to move around but you still have the full mass to move.  Then you have less friction with the ground so it is harder to get moving as well as stop.  The lower gravity makes them appear to move slower as they have more "hang time" vertically but if you watch their arms they still move at normal speeds.  Speeding up the footage makes their arms move way too fast.

No, it's not.

An airplane's forward motion is much too low for this to work. The dashed blue lines in the illustration would be far shorter for an airplane, but the green inward-pointing arrows would be the same size, so it wouldn't follow the red circular path; it would intercept the Earth.
 
Quote
They fly around the Earth everyday. The airplane's engine is providing the inertia to cause the airplane to fly forward and gravity is trying to pull the airplane down.
No, the engine is providing thrust, which is necessary to overcome drag from air resistance. The wings provide lift, which is necessary to overcome weight, which is due to gravity.

Quote
The pilot has to maintain altitude and direction and a nice curved path is maintained around the Earth just like a satellite does. It is really a balancing act between gravity and inertia. Gravity is trying to pull it down, but inertia keeps it from happening.
No, if thrust equals drag and lift equals weight, the airplane flies at a constant altitude and speed. More generally, the vector sum of thrust, drag, lift and weight determines whether the aircraft gains or loses altitude, speeds up or slows down; if they sum to zero, it has no altitude change and maintains speed.

Quote
If the airplane's engine stops, gravity will take over and it will free fall to the ground.
No, it will glide to the ground, which isn't free fall, because the wings provide some lift if they're moving forward. With the loss of thrust, drag will reduce speed, which reduces lift, so weight exceeds lift and the aircraft loses altitude.

Quote
If the satellite's inertia runs out, then the satellite will free fall to the ground.
Yes. But what would cause this?

As it is, because there is a very tenuous atmosphere even at the heights most satellites orbit, they do lose a little energy (and momentum) colliding with these particles, and their orbits do decay unless additional energy is supplied, usually in the form of a rocket engine in some form. This is a very slow process until the satellites get very low (for a satellite), however.

Quote
In this case, the only real difference between a satellite and an airplane is how high each fly.
Nope. They are completely different.

Not true... stay tuned.

They're right, too!

Quote
That can't be true because inertia is what keeps satellites and airplanes from free falling to the ground in the first place.
Satellites are in free-fall. Because their forward motion is high, the ground is falling away at the same rate, though. Airplanes stay aloft because of lift generated (mostly) by the wings, which causes drag, which must be overcome by thrust. They are not is free fall when flying normally.

--> An example of an airplane in free fall is the "Vomit Comet", whose passengers do float around inside the airplane

Quote
Others say they float around because there is no gravity in space. That is not true, there is only 10% less gravity on the ISS then on Earth and that is not enough difference to keep passengers on an airplane from floating around.
You are correct. Zero gravity is a misconception and does cause some confusion. Passengers in an orbiting spacecraft are in the same orbit as the spacecraft they're in, and both are in free fall, so there is nothing resisting the acceleration of gravity toward the center of the Earth, so they feel no weight. Gravity is very much in effect.

Quote
So, I sit here and wonder if the videos of the ISS true, false or I'm I totally off base on my reasoning?
The first and last are correct.

I would say the picture is just for providing an illustration. It is certainly not to scale. I've watched the ISS flight around the Earth and it makes a nice smooth curved path. 

No, the engine is providing thrust, which is necessary to overcome drag from air resistance. The wings provide lift, which is necessary to overcome weight, which is due to gravity.

You don't like it when I said the engine provides inertia? I can use thrust if you like. I understand that an airplane flies in the atmosphere and uses wings to give lift. However, The ISS has weight too and gravity is trying to pull it down also. I don't see much difference here between an airplane and the ISS. So this does not show why the astronauts float.

No, if thrust equals drag and lift equals weight, the airplane flies at a constant altitude and speed. More generally, the vector sum of thrust, drag, lift and weight determines whether the aircraft gains or loses altitude, speeds up or slows down; if they sum to zero, it has no altitude change and maintains speed.

 How is this different for the ISS. I don't see your point. How does this cause the Astronauts to float around?

No, it will glide to the ground, which isn't free fall, because the wings provide some lift if they're moving forward. With the loss of thrust, drag will reduce speed, which reduces lift, so weight exceeds lift and the aircraft loses altitude.

I believe that a large plane will glide a little if the engines fail, but they will take a nose dive directly to the ground. I don't see why this causes Astronauts to float.

Yes. But what would cause this?

As it is, because there is a very tenuous atmosphere even at the heights most satellites orbit, they do lose a little energy (and momentum) colliding with these particles, and their orbits do decay unless additional energy is supplied, usually in the form of a rocket engine in some form. This is a very slow process until the satellites get very low (for a satellite), however.

I realize all this. I still don't see why Astronauts float.

Nope. They are completely different.

 When I said the only real difference between an airplane and a satellite was how high they fly, I meant that one flies in the atmosphere and one flies in no atmosphere and because of this there would be physical differences between them. I guess I didn't explain that well enough.

Not true... stay tuned.

I'm staying tuned.

They're right, too!

I don't believe so. Inertia keeps it from happening.

Satellites are in free-fall. Because their forward motion is high, the ground is falling away at the same rate, though. Airplanes stay aloft because of lift generated (mostly) by the wings, which causes drag, which must be overcome by thrust. They are not is free fall when flying normally.

--> An example of an airplane in free fall is the "Vomit Comet", whose passengers do float around inside the airplane

 You say that satellites are in freefall because their forward motion is high and the ground is actually falling away from them at the same rate. If that is the case then there should be less gravity caused by centripetal force and the straight-line path due to the high rate of inertia should cause the object to go flying away from Earth and not curve around it. Like I said before, airplanes do not fly in outer space so they do need an engine and wings to fly and maintain the inertia to keep them flying around the Earth the same way the ISS does. Granted, the "Vomit Comet" does cause the passengers to float around because the plane is heading straight towards the ground at a high rate of speed and the passenger do float around. So would the Astronauts float around if the ISS was heading straight towards the ground.  However, that is not the normal way an airplane or the ISS flies around the Earth. Watch some videos of the ISS in flight, they follow the Earth's curvature perfectly because of Inertia or thrust and wings in the airplanes case, in order to keep gravity or whatever it is from pulling them to the ground. There has to be a better answer as to why Astronauts float around.

This picture shows an object following a path around the Earth at a precise distance above the Earth because inertia is causing the object to fly straight and gravity wants to pull the object down to Earth. What you have is a nice curve flight around the Earth.
This depiction of "reality" is impossible.
Any drawing showing a circular orbit of an object around the Earth is bogus. Geostationary satellites are not only physically but also conceptually impossible.
In the vicinity of the Earth 3 main gravitational forces play a role (excluding the effects of our neighbors Mars and Venus, giant planets farther away and effects of the Milky Way).
Any object in space around the Earth must be susceptible (and thus the orbit of such an object is defined by that) to the gravitational fields/forces of:
- Earth
- Moon
- Sun
Loosely speaking what you say has some validity, at least it is something to be considered in looking at the orbits of not only satellites, but the moon itself.  What makes it harder to grasp initially is that the sun's gravitational field at the moon is greater than that of the earth, so it is hard to see why the moon orbits the earth and not the sun. 
Certainly we know the moon does orbit the earth, then the earth-moon combination orbits the sun.  The calculations a way beyond me, but a so-called "Hills Sphere" around the earth can be defined where a satellite (such as the moon) will orbit the earth and not be trapped by the sun.  You can read up on it in https://van.physics.illinois.edu/qa/listing.php?id=18501 (https://van.physics.illinois.edu/qa/listing.php?id=18501).

For artificial satellites orbiting the earth there is less of a problem because:
1) they are much closer to the earth than to the moon,
2) the mass of the moon is only about 1.2% the mass of the earth.
Since the gravitational field the satellite is subject to depends on m/d^2 the moon has much less effect even for geostationary orbits.
Nevertheless it is a matter that has been analysed in detail way back before 1961.  You can read up in: Luni-Solar  Perturbations of the Orbit of an Earth Satellite G. E. Cook, The Geophysical Journal of the ROYAL ASTRONOMICAL SOCIETY Vol. 6 No. 3 April 1962.  see http://gji.oxfordjournals.org/content/6/3/271.full.pdf (http://gji.oxfordjournals.org/content/6/3/271.full.pdf)
 
We know that the Earth and Moon are in an eternal tidal orbital dance with each other; the gravitational pull of the Earth at least works to the Moon (~380,000 km) and the center of gravity of this combined system is skewed. Even if a "geostationary" satellite were possible, it would orbit around that "point" (it's a path as Moon and Earth move in 3D) rather than around Earth.
If when you say "orbit around that point" you mean the satellite orbits the barycentre of the earth-moon combination, no that is not true any more than the moon orbiting the barycentre of the earth-sun combination - that would be inside or very near the sun.
A "geostationary satellite" is certainly possible, there are numerous ones in orbit.  The moon's gravitational field will have some effect, but because of the inverse square law and the moon's mass being so must less the effect is small.  Orbital corrections for these satellites are done, and when they run aout of fuel for this task their service life quickly ends.

Reciprocally our grand small sister gives us the effects of spring tides; it is able to lift half the water mass on the planet by meters and push it down by the same "pulling effect" (no physical term) on the antipodal side of Earth.
Yes, the moon (and sun) do control our tides, but do not so much bodily lift the oceans as cause the ocean water to move towards where the moon-sun combination has the greatest effect.  The second tide (when the moon is on the opposite side) happens because the gravitational effect of the moon-sun is least there, so the rotation of the earth causes the bulge on that side.
Hence:
1) the time of high or low tide lags the moon and is also greatly affected but the local ocean floor profile, so much so that some places get extreme tides (Bay of Fundy), and some places get almost no tide (parts of Western Australian Coast).
2) small bodies of water do not experience significant tides, even the Mediterranean Sea has tides of only a few centimetres.

Then we have a huge Sun which is acting on this whole system as well.
To paint a circular orbit around Earth like the Earth-Moon gravitational field and the gravitational effects of the Sun do not exist is ridiculous science fiction showing a lack of understanding of the dynamic forces of space.

While the whole system is certainly extremely complicated, luckily the effects of bodies other than the earth on artificial satellites of earth is quite small - maybe more by good luck that good management.  The sun, other planets and especially the other stars have no significant effect till we get much further from earth that geostationary satellites.

Maybe you'll call this a load of rubbish, but whatever there it is!
E&OE as they say.

Yendor, the ISS is falling.  The people inside are falling with it.  It's lateral velocity means it continually misses the planet. 

I don't know what is so hard to understand about all this.  Do you think the astronauts should be held to the 'floor' of the ISS or held to the 'ceiling' if they can't possibly 'float' (as you say)?

See here (http://www.theflatearthsociety.org/forum/index.php?topic=65151.msg1739362#msg1739362) for context.


No, it's not.

An airplane's forward motion is much too low for this to work. The dashed blue lines in the illustration would be far shorter for an airplane, but the green inward-pointing arrows would be the same size, so it wouldn't follow the red circular path; it would intercept the Earth.

I would say the picture is just for providing an illustration. It is certainly not to scale.
It can still be used as a basis to compare different flight paths, though. Do you not understand what it's illustrating?

Quote
I've watched the ISS flight around the Earth and it makes a nice smooth curved path. 
Yes, it does. Orbits are smooth curves. So?

Quote
No, the engine is providing thrust, which is necessary to overcome drag from air resistance. The wings provide lift, which is necessary to overcome weight, which is due to gravity.

You don't like it when I said the engine provides inertia? I can use thrust if you like.
Do you think inertia and thrust are interchangeable? Really? They're not.

No wonder you have difficulty understanding this.

Quote
I understand that an airplane flies in the atmosphere and uses wings to give lift. However, The ISS has weight too
No, it has mass but no weight because it's in free fall.

Quote
and gravity is trying to pull it down also.
That's the centripetal acceleration you keep bringing up. It exactly matches the rate of increase in distance from the center of the Earth a straight line path would have at all times in a circular orbit.

Quote
I don't see much difference here between an airplane and the ISS.
Since you're confusing inertia with thrust, and a very muddled idea how things work in reality, this is not surprising.

Quote
So this does not show why the astronauts float.
Your not understanding the difference between an airplane and the ISS is why you don't understand why the astronauts float within (and near) the ISS. Airplanes in level flight are not in free fall. The ISS is (almost) always in free fall. So is everything inside it.

No, if thrust equals drag and lift equals weight, the airplane flies at a constant altitude and speed. More generally, the vector sum of thrust, drag, lift and weight determines whether the aircraft gains or loses altitude, speeds up or slows down; if they sum to zero, it has no altitude change and maintains speed.

 How is this different for the ISS.
Airplanes flying in the atmosphere require thrust to overcome atmospheric drag, and require lift to compensate for weight because a free-fall trajectory would intercept the Earth. The ISS, and all satellites in stable orbits, have no atmospheric drag, so they require no thrust, and have no weight, even though they have mass, because they are in free fall, so they don't need lift. Needing thrust and lift to overcome drag and weight is different from not needing thrust and lift because there is no drag and weight. That's how they're different.

Quote
I don't see your point. How does this cause the Astronauts to float around?
Both the astronauts and the spacecraft they're in are in the same orbit, so they follow the same path through space, so their relative motions are zero.

Quote
No, it will glide to the ground, which isn't free fall, because the wings provide some lift if they're moving forward. With the loss of thrust, drag will reduce speed, which reduces lift, so weight exceeds lift and the aircraft loses altitude.

I believe that a large plane will glide a little if the engines fail,
Yes, they will glide some because as long as there is forward airspeed the wings will produce some lift. The glide ratio of a Boeing 747-200 is 15:1; that is, it can travel 15 km horizontally for each 1 km of altitude it loses.

Quote
but they will take a nose dive directly to the ground.
This doesn't necessarily follow. Look up British Airway Flight 9 to see the particulars of the record for the longest glide of a non-purpose-built aircraft (https://en.wikipedia.org/wiki/British_Airways_Flight_9) that stood for years.  Since FE enthusiasts seem to like youtube videos, here's a 45-minute-long, but entertaining, documentary about it: (http://)

Of course, there's even a list of long glides in airliners (https://en.wikipedia.org/wiki/List_of_airline_flights_that_required_gliding).

So, no... complete engine failure doesn't necessarily mean a nose dive directly to ground.

Quote
I don't see why this causes Astronauts to float.
Astronauts floating in the ISS aren't aboard airplanes. The ISS is different from an airplane. That's not hard to see.

Quote
Yes. But what would cause this?

As it is, because there is a very tenuous atmosphere even at the heights most satellites orbit, they do lose a little energy (and momentum) colliding with these particles, and their orbits do decay unless additional energy is supplied, usually in the form of a rocket engine in some form. This is a very slow process until the satellites get very low (for a satellite), however.

I realize all this. I still don't see why Astronauts float.
Yes, you've made that plain. Either you're lying about not seeing why astronauts float, you're very slow on the uptake, or you're trying really, really hard not to understand. You probably know which of these is right. Which one is it?

Quote
Nope. They are completely different.

 When I said the only real difference between an airplane and a satellite was how high they fly, I meant that one flies in the atmosphere and one flies in no atmosphere and because of this there would be physical differences between them. I guess I didn't explain that well enough.
OK. When you say the only real difference is the altitude, you didn't mean that. Got it.

Quote
Not true... stay tuned.

I'm staying tuned.

They're right, too!

I don't believe so. Inertia keeps it from happening.
If "inertia" is the same as "thrust and lift" to you, then, yeah. But it's not, really. I can see why this is hard for you to understand.

Quote
Satellites are in free-fall. Because their forward motion is high, the ground is falling away at the same rate, though. Airplanes stay aloft because of lift generated (mostly) by the wings, which causes drag, which must be overcome by thrust. They are not is free fall when flying normally.

--> An example of an airplane in free fall is the "Vomit Comet", whose passengers do float around inside the airplane

 You say that satellites are in freefall because their forward motion is high and the ground is actually falling away from them at the same rate. If that is the case then there should be less gravity caused by centripetal force and the straight-line path due to the high rate of inertia [inertia isn't a rate; I think you mean speed] should cause the object to go flying away from Earth and not curve around it. Like I said before, airplanes do not fly in outer space so they do need an engine and wings to fly and maintain the inertia speedto keep them flying around the Earth the same way the ISS does[going around the Earth is about the only thing they might have in common]. Granted, the "Vomit Comet" does cause the passengers to float around because the plane is heading straight towards the ground at a high rate of speed and the passenger do float around[they're not going "straight towards the ground", they follow a flight path that mimics a ballistic curve]. So would the Astronauts float around if the ISS was heading straight towards the ground. 
If that was a ballistic trajectory, yes.

Quote
However, that is not the normal way an airplane or the ISS flies around the Earth [not normal (but, obviously possible) for an airplane, normal for the ISS]. Watch some videos of the ISS in flight, they follow the Earth's curvature perfectly because of Inertia or thrust and wings in the airplanes case, in order to keep gravity or whatever it is from pulling them to the ground.
Inertia or thrust and wings? What?

Quote
There has to be a better answer as to why Astronauts float around.
Nope. Both the astronauts and the spacecraft they're in are in the same orbit, so they follow the same path through space, so their relative motions are zero. They're both in free fall. What's wrong with that answer? "I don't like it" is not an explanation. Nor is "I don't understand it.

If the so called ISS is orbiting or falling around the Earth like we are told then something must be acting on it to push it away as the so called gravity of Earth tries to pull it down.

Now if it's the speed of the ISS that keeps it up it must require something more than gravity. Why?

Well, if we are told that an aeroplane stays up high by going fast around Earth's supposed ball shape and it also uses the atmosphere to give it lift to keep it orbiting against the so called pull of gravity, then surely your space should have something more for the ISS.
Any ideas?

The ISS simply has enough lateral motion that the ground falls away aat the same rate as the ISS falls towards the earth. The result is that the same altitude (ish) is maintained.

Aircraft have to create lift using aerofoils and the atmosphere to balance against gravity. This typically requires thrust from engines or in the case of gliders thermal up draughts.

Imagine you are moving forward at constant speed. A constant force appears on you in direction from your left to your right (always perpendicular to your forward movement). What will happen? You will start moving in curved lines, circles as special case.

Maybe you'll call this a load of rubbish, but whatever there it is!
E&OE as they say.

Thank you for this extensive post. This is the level of thinking I was looking for.

Unfortunately both the post and the page you link to (it starts off well, the lower part with the Langrangian "points" is fantasy) is a mix of science and NASA Disney "science".

I will address the points trying to unravel the mysteries.

Quote
Loosely speaking what you say has some validity, at least it is something to be considered in looking at the orbits of not only satellites, but the moon itself.  What makes it harder to grasp initially is that the sun's gravitational field at the moon is greater than that of the earth, so it is hard to see why the moon orbits the earth and not the sun. 
Certainly we know the moon does orbit the earth, then the earth-moon combination orbits the sun.  The calculations a way beyond me, but a so-called "Hills Sphere" around the earth can be defined where a satellite (such as the moon) will orbit the earth and not be trapped by the sun.  You can read up on it in https://van.physics.illinois.edu/qa/listing.php?id=18501 (https://van.physics.illinois.edu/qa/listing.php?id=18501).

I see what is meant here and the "change of the field" is the defining factor and not the field itself. That makes sense.

The gravitational field of our central celestial body, the Sun, even extends all the way to the Oort cloud (https://en.wikipedia.org/wiki/Oort_cloud) @ ~2000-5000 AU, some may say even 50,000 AU (0.79 ly). This Oort cloud is theoretical; it is postulated, so we don't know if it really exists. But if it does, it means the gravitational field of the Sun is amazingly large.

If we disregard the Oort cloud as being too theoretical, empirical science is my basis, not theoretical, then the Kuiper belt (https://en.wikipedia.org/wiki/Kuiper_belt) becomes the outermost sphere of influence of the Sun's gravitational force, at around 50 AU let's say to have a nice round number. Not too much more than Pluto (with its highly elliptical orbit; 30-49 AU).

Quote
For artificial satellites orbiting the earth ...

So this "information" I don't use. I stick to science and try to avoid these fantasies about "artificial satellites orbiting the Earth".
 
Quote
If when you say "orbit around that point" you mean the satellite orbits the barycentre of the earth-moon combination, no that is not true any more than the moon orbiting the barycentre of the earth-sun combination - that would be inside or very near the sun.

This is a good point, but why can the Earth-Moon system not orbit the barycentre of the Sun? You separate the Moon now from the Earth-Moon system, but it's a combined system; you cannot separate Earth and Moon as they are in such a strong gravitational dance.

The Earth's Moon is not pulled into the Sun just like the moons of other planets are not pulled into the Sun. Their stable orbits (by definition; gravitational equilibrium) are functioning for billions of years. So while the gravitational field of the Sun is strong and may act strong on Moons, it still is the gravitational field of the planet they orbit that defines the orbit; otherwise there wouldn't be moons at all; all would be pulled into the Sun.

Also, if the Sun would attract everything else, there would be no meteorites (on Earth, Moon or Mercury) yet we have extensive proof they do exist and crash into celestial bodies, up to the present (Arizona and the daily meteorites reaching Earth's surface).

Quote
Orbital corrections for these satellites are done, and when they run aout of fuel for this task their service life quickly ends.

Yes, this is complete fantasy, not science. "Orbital corrections", corrections from what exactly? Fuel is useless in space.

Quote
Yes, the moon (and sun) do control our tides, but do not so much bodily lift the oceans as cause the ocean water to move towards where the moon-sun combination has the greatest effect.  The second tide (when the moon is on the opposite side) happens because the gravitational effect of the moon-sun is least there, so the rotation of the earth causes the bulge on that side.
Hence:
1) the time of high or low tide lags the moon and is also greatly affected but the local ocean floor profile, so much so that some places get extreme tides (Bay of Fundy), and some places get almost no tide (parts of Western Australian Coast).
2) small bodies of water do not experience significant tides, even the Mediterranean Sea has tides of only a few centimetres.

Ok, the effect of the tidal force of the Moon can be observed differently and indeed the geometry of the basin is much more important for tide than the force of the Moon as normal tides in the Mediterranean are insignificant, rightly pointed out by you.

Still that doesn't dispute the fact that the gravity of Sun and Moon do act on Earth. Quantifying all this is virtually impossible, but we observe the effects and you've described the process in enough detail for everybody to understand, thanks again.

Quote
While the whole system is certainly extremely complicated, luckily the effects of bodies other than the earth on artificial satellites of earth is quite small - maybe more by good luck that good management.

That is a claim "quite small" and an explanation for the claim "maybe good luck". It is however based on the premise that artificial satellites would work, something which is not the case as artificial satellites cannot exist in the first place.

Quote
The sun, other planets and especially the other stars have no significant effect till we get much further from earth that geostationary satellites.

Also this would be impossible. The Sun definitely works within the Earths SOI as shown by the tidal forces. Again, it is based on a false premise.

Yendor, the ISS is falling.  The people inside are falling with it.  It's lateral velocity means it continually misses the planet. 

I don't know what is so hard to understand about all this.  Do you think the astronauts should be held to the 'floor' of the ISS or held to the 'ceiling' if they can't possibly 'float' (as you say)?

silhouette, I know you mean well, but I've heard the same thing as you 1000 times, 'the ISS is free falling around the Earth and that is why the astronauts are floating'. I do take issue with you when you say demeaning things like, "I don't know what is so hard to understand about all this." Do you think I can't comprehend the meaning of that and you are trying to explain it to me in a simpler way? My point to this is, as I stated right off the bat, satellites and the ISS can't be in freefall because of lateral movement caused by the inertia of the orbiting unit. If in fact the objects that are orbiting the Earth lose their inertia, then they would freefall back to Earth. Now, my question to you is, I don't know what is so hard to understand about all this?

To me, the notion that orbiting satellites or the ISS are in free fall back to Earth but keeps missing it is ridiculous. People are also floating around because of it. What happened to gravity pulling things to the center of the Earth. This whole notion makes it sound like gravity pulls things towards the side of the Earth. The definition of free fall alone should be enough to convince someone this is wrong.

 free fall
noun
1.
downward movement under the force of gravity only.

Free fall is the downward movement under the force of gravity only. the key here is 'gravity only'. The satellite is not under the influence of the force of gravity alone. If flying objects were, then yes they would probably free fall back to Earth and not miss it. The force of Inertia is also in play here. Inertia is what keeps the satellite's velocity going strong. We use the word inertia because the satellites and the ISS are claimed to be in a vacuum, free from atmospheric resistance. If we are talking airplanes then we use the word thrust because they fly in the atmosphere and there is atmospheric resistance. The velocity is what keeps gravity from pulling flying objects to the ground. If velocity is not enough then flying objects will fall to the ground. Unless it is a blimp or a hot air or helium filled balloon.

Inertia keeps a mass moving in a straight line at a constant speed (i.e. keeps it moving at a constant velocity - that's what inertia does). A force is necessary to cause it to change velocity. The force of gravity causes a satellite in a circular orbit to change direction, but not speed.

No, lift is what keeps these things from falling to the ground. Lift for an airfoil (like an airplane wing) is a function of air speed; if the air speed is too low, there is not enough lift to overcome the airplane's weight, and it loses altitude. Lift for aerostats (lighter-than-air craft) is due to buoyancy, and is not dependent on air speed.

That is really a very telling article and should be read before anyone criticises too severely what I put here.

In its simplest from the FET uses the Equivalence Principle to replace the gravitational field observed on the earth's surface.  I contend that this is not a valid application of the Equivalence Principle.

Quote
we [...] assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system.
— Einstein, 1907
This very brief statement of Einstein needs a little qualification.  If the reference system under consideration is not small enough for the gravitational field to be considered constant over its range then there can be no complete physical equivalence.

This is stressed in the fuller presentation of the Equivalence Principle.
Quote
Importance of the Equivalence Principle

An equivalent formulation of the Principle of Equivalence is that at any local (that is, sufficiently small) region in spacetime it is possible to formulate the equations governing physical laws such that the effect of gravitation can be neglected. This in turn means that the Special Theory of Relativity is valid for that particular situation, and this in turn allows a number of things to be deduced because the solution of the equations for the Special Theory of Relativity is beyond the scope of our course, but is not particularly difficult for those trained in the required mathematics.
  from http://csep10.phys.utk.edu/astr162/lect/cosmology/equivalence.html (http://csep10.phys.utk.edu/astr162/lect/cosmology/equivalence.html)
In the case of the earth we can readily measure variations in the gravitational field.  The most obvious is due to altitude, but there are more subtle variations due to the presence of ore bodies as used in gravimetric surveys for minerals.
If the earth is spherical there is also the variation in direction as we move over the earths surface.  In the context of a globe earth ~ flat earth discussion this is harder to "pin down" as it involves measuring small angular differences over large distances, so I will leave it out of the discussion.

As a result this the concept of Universal Acceleration can replace a gravitational field only if the reference system (the whole earth) is sufficiently small for the gravitational field to be considered constant over the whole system.

This is clearly not satisfied, so the concept of Universal Acceleration cannot be be used to replace the gravitational field.
 and shows quite clearly that UA is simply an invalid substitute for the observe "gravitational field".

Even if a "geostationary" satellite were possible, it would orbit around that "point" (it's a path as Moon and Earth move in 3D) rather than around Earth.

I know I'm late but I just have to point this out. The center of mass of the Earth-Moon system is actually inside the Earth.

Welcome, yes, that has been shown with a simple animation already here (http://www.theflatearthsociety.org/forum/index.php?topic=65140.40#.VnVfEL-Wkk8). So a "geostationary orbit", even if that were technically possible, would be an orbit around that center of mass inside the Earth and will never produce a circular geostationary orbit whose center of mass is the exact core of the Earth.

Alright Papa, here's an example that might clear things up. When a ball hangs by a string, the string is acting on the ball with an upward force. This force is called tension. Imagine the ball being swung in a circle (let's say it's on a frictionless table just to rule out any vertical forces). The ball is being pulled towards the center of the circle by the tension from the string. Side note: you can calculate exactly how strong this force is with the formula F = mv2/r where F is the tension force in Newtons, m is the mass of the ball in kilograms, v is speed of the ball in meters per second, and r is the length of the string in meters. So, if the ball is constantly being pulled towards the center, why doesn't it ever reach the center? Simply put, the ball is moving fast enough to "miss" the center. This is what people mean when they say objects in orbit "miss" the ground.

Back to you again alpha,
I enjoy this debate, but I do want to keep it civil. Let's not get into a pissing contest over this matter. I don't claim to have learned everything about science and you will catch me saying things that doesn't coincide with what you were taught. That doesn't mean you have to call me out about it and make me look foolish. Let's start again with a clean slate on this matter and see if we can find some common ground. The subject of this thread is, "Why do astronauts on board ISS float around?". My thoughts are this, I've always heard that satellites stay in orbit because they free fall around the Earth and that is why astronauts float around inside the ISS. I pondered this notion and wondered why they say this because it really made little sense to me. I thought about airplanes, they don't fall around the Earth and the passengers don't float around. So I wondered what is the differences between a satellite and an airplane. They both fly around the Earth. So this is what I came up with.

1. A satellite is launched into orbit and it flies around the Earth.
2. An airplane flies off the runway and it too flies around the Earth.
3. Without getting on another subject, Let's say gravity tries to pull both satellites and airplanes back down to Earth.
4. Inertia keeps the satellite and an airplane from allowing gravity to pull them both back down to Earth.

It just seems to me that if an airplane could fly outside Earth's atmosphere, it would act no different then it does flying inside Earth's atmosphere.

Now, please go to the below NASA website and read what it says about satellites.
Take note it says,"When these two forces are equal, the ball remains in orbit", meaning gravity and inertia. (You had mentioned before that gravity was the only force acting upon a satellite.)

http://www.gma.org/surfing/satellites/inorbit.html   (http://www.gma.org/surfing/satellites/inorbit.html)

My thoughts are this, If these two forces, gravity and inertia are acting on an airplane and a satellite to keep them both flying around the Earth, then when does this free fall come into play? Notice too that the article does say, "A satellite's forward motion is controlled by rockets. When the rockets are not fired, inertia keeps the satellite going in one direction." So, rockets provide the inertia for satellites and a jet engine provides the inertia for airplanes. I realize that the rockets are probably not used that much because a satellite is flying in a vacuum with little resistance. However, it does clearly say inertia is required for a satellite to fly around the Earth. The only way, that I can see a satellite in free fall is if inertia gives out and then gravity can pull it back down to Earth. This too will happen with an airplane. Lets not get into, well a plane will glide because of its wings and some planes will glide longer than others. That is just meaningless and does nothing but try and change the subject. So alpha, without getting all pissed off, please explain to me, as simple as possible, in your own words, without math and not saying so and so said it works this way, why my thoughts are all wrong.

1. A satellite is launched into orbit and it flies around the Earth.
at an average speed of 17,000mph.

Quote
2. An airplane flies off the runway and it too flies around the Earth.
at an average speed of 100-200mph.  Airliners cruise at 500-600mph.

Quote
3. Without getting on another subject, Let's say gravity tries to pull both satellites and airplanes back down to Earth.
4. Inertia keeps the satellite and an airplane from allowing gravity to pull them both back down to Earth.

Inertia keeps the satellite moving at that high-rate of speed while gravity pulls it toward Earth.  It continually misses, and there is almost nothing to slow it.

Inertia will let the airplane glide for a bit before dropping.  Without the constant thrust from the propeller, etc, wind resistance would slow it quickly.  Lift generated by the wings is what keeps it flying. 

Quote
It just seems to me that if an airplane could fly outside Earth's atmosphere, it would act no different then it does flying inside Earth's atmosphere.
At it's same atmospheric speed, it would drop quickly as there would be no air for the wings to provide lift.

It is in free-fall.  Inertia keeps it moving sideways fast enough that is keeps missing the planet.  Thrust brought it up to that speed (or is used occasionally to keep it at that speed)

Quote
This too will happen with an airplane.
In the atmosphere, yes.  It will lose it's speed, which is required in addition to air for the wings to provide lift.  Outside the atmosphere at it's normal speed, yes.  It would not be going fast enough.  If sped up to the same speed as a satellite, it would act the same as a satellite.

1. & 2. That fast speed is not necessary. They say it has to be that fast so it can free fall around the Earth. Often times they show a cannon firing a cannonball to demonstrate it has to go that fast in order to miss the Earth and fly around it. You know that is not true because Airplanes fly just fine around the Earth going no wheres that speed.

3. & 4. What you say is the same as what I said except you say, "It continually misses". Well it does miss hitting the Earth, but that does not mean it is in free fall. An airplane misses the Earth and it is not in free fall.

5. The only reason an airplane can't fly outside the atmosphere is because the engines need air. If the airplane had a rocket engine like a satellite, (remember reading this from the website I gave you?), "A satellite's forward motion is controlled by rockets. When the rockets are not fired, inertia keeps the satellite going in one direction." The airplane would need no wings in space because there is no air in space. It would simply fly in a straight path because the rocket engine would provide the necessary inertia and gravity would keep it from flying away from the Earth.

6. Why do you insist on calling it free fall? If gravity is trying to pull an object down but inertia is overcoming the pull of gravity, then an object is simply flying. You see this everywhere. When a person jumps his muscles will get him off the ground, but gravity gets him back down. A person with stronger muscles can jump higher and further, but gravity will still pull him down. This is what is happening in space as well, only because of the vacuum of space, inertia is is much stronger because there is little resistance to slow the satellite down and gravity will not pull it down. When inertia does become weaker and gravity begins to pull it down, the rockets will kick in and boost the inertia and everything is back to normal again. There is no free fall here, only when they purposely want to bring it down. Free fall is:  Any object that is being acted upon only by the force of gravity is said to be in a state of free fall.  Wouldn't you think that if a satellite was in actual free fall, gravity would keep pulling and pulling it in towards the center of the Earth until it reached the Earth's atmosphere where it would eventually burn up? What would stop it from happening? The puny rocket engines they have on satellites sure would not stop it.
 
7. You are back to speed again. The speed of the satellite  is the speed they figured out they need to use in order to keep people believing satellites are free falling around the Earth.

If you don't believe what i believe that's fine. At this point in time it just seems to make sense to me and maybe no one else.

The problem is you don't know what you are talking about.

1&2. The velocity for satellites are well know. A good estimate is velocity=sqrt(Gme/r)
3&4. They are in close to freefall, as in, no force is acting on them other than the slight atmosphere present.
5. We understand orbit.
6. As stated, freefall is the absence of a force.
7. No, it's the actual speed needed.  You can see satellites yourself.

If you don't want to be called out and made to look foolish for saying things that are just wrong, then don't make statements like "the notion that orbiting satellites or the ISS are in free fall back to Earth but keeps missing it is ridiculous." If you don't understand, you might say "I just don't see how an orbiting satellite can be in free-fall and keep missing the Earth."

Let's start again with a clean slate on this matter and see if we can find some common ground. The subject of this thread is, "Why do astronauts on board ISS float around?". My thoughts are this, I've always heard that satellites stay in orbit because they free fall around the Earth and that is why astronauts float around inside the ISS. I pondered this notion and wondered why they say this because it really made little sense to me. I thought about airplanes, they don't fall around the Earth and the passengers don't float around. So I wondered what is the differences between a satellite and an airplane. They both fly around the Earth. So this is what I came up with.

[Trying to be as nice as possible] Why do you think an airplane flying in the Earth's atmosphere is no different than if it were in orbit outside the atmosphere? They're completely different. In order for an object at, say, 10 km above mean sea level (33,000 feet, roughly) to stay at a constant altitude without lift, like a satellite in free fall, it would have to be traveling at close to 17,000 mi/hr. Airplanes can't fly this fast through the atmosphere at 10 km altitude because drag increases exponentially with speed, so they need lift to stay aloft, so they aren't in free fall. It really is that simple.

No, inertia is a property of mass. The rockets provide energy by doing work (applied force over distance). Occasionally inertia is used to mean momentum, which may be where you're getting confused. Momentum isn't a force, either, though.

Your notion that "free fall" implies "moving directly toward the center of the Earth" is incorrect. Free fall means "accelerating directly toward the center of the Earth" when the only force is the gravitational attraction of the Earth. Momentum isn't a force, even though some web page you found might kinda sorta make you think it is. If you have a lateral velocity in addition to the downward acceleration, your free-fall path is not a straight line directly toward the center of the Earth, it's a curved path. For instance, if you're hanging from a bar just beyond the edge of a cliff and let go, you're in free fall[nb]Neglecting air resistance.[/nb] until you hit the ground or something else. If you run as fast as you can off the edge of that same cliff, you're also in free fall[nb]Neglecting air resistance.[/nb] once your feet go past the edge, but you follow a different trajectory, a curved path that carries you away from the cliff face, but you're still in free fall[nb]Neglecting air resistance.[/nb].

Yendor, the airplane stays in the air because it has engines to provide thrust and wings to provide lift. If you shut down the engines and remove the wings from the plane, the passengers will enter free fall and start to float. The reason the plane falls back to the ground but the satellite doesn't is because of their speed and altitude.

Just for fun, we can calculate the required speed for a circular orbit at any given altitude. We can use the formula a = v2/r where a is acceleration in m/s2, v is speed in m/s, and r is distance from the center of the Earth in m. Gravitation acceleration is given by the formula GM/r2 where G is the gravitational constant (6.674 x 10-11, M is the mass of the Earth (5.972 x 1024 kg, and r is the distance to the center of the Earth. The radius of the Earth is 6.371 X 106 m, so we need to add that to our altitude to find the distance to the center.

Let's try with a typical airplane. A typical airplane flies at about 10,000 meters above the ground. Add that to the radius of the Earth, and we get 6,381,000 m. That gives us a gravitational acceleration of 9.79 m/s2. Plug that into our circular motion equation and we get 9.79 = v2/6381000. Solve for v and we get 7903.3 m/s, several times faster than any airplane has ever flown. We can see that a conventional aircraft is simply incapable of achieving a circular orbit at typical altitudes. Before you say "what about non-circular orbits", the speed required for an elliptical orbit would actually be greater than a circular orbit, assuming you want the lowest point in the orbit to be above the ground.

1. No hard feelings...

2. The notion an object will fall around the Earth if enough velocity is placed upon it was conceive by Newton during one of his thought experiments. Correct me if I'm wrong, but I believe this is correct. Alpha, you are correct, I shouldn't say it is ridiculous, I should say it sounds ridiculous to me. I do understand the concept, it simply seem impossible to me that you can have an object flying around the Earth at 17,000 mph or so and it will follow a nice smooth path and never enter the Earth's atmosphere. They call this free falling around the Earth.

3. We can forget about whether inertia is a force or not or why a satellite has to be flying so fast or that I don't know how airplanes work. All that stuff is irrelevant.  I simply used the analogy between a satellite and an airplane to try and show that I believe a satellite could only fly in space the same way an airplane flies in the atmosphere. There should be little difference between them except for the obvious reasons an airplane can't fly without air for the engines. You see, I don't believe what we are told is true. We are told that a satellite is launched into space by a rocket, simply released from the rockets grips and then it will free fall back to Earth. However, it does not crash into Earth mind you, it simply floats around the Earth in a nice smooth curved path going 17,000 mph or so. It will continue doing this for ever and ever, or until they decide to allow it to enter the Earth's atmosphere and burn up. Or they can send it to a place far far away where it can live happily ever after. To me, all this sounds untrue. I don't believe it can be this way. I'm a very technical person. I've spent nearly my whole life working as an electrical engineer. I've even designed products that were supposedly used on satellites.  I know what everyone is thinking. I should know better and how in the world would I think this way. Let me tell you what I believe. I believe that if there are crafts flying around the Earth, then they are flying inside the Earth's atmosphere. I don't believe they are traveling 17,000 mph and free falling back to Earth. I believe they would be flying like airplanes fly or other types of air vehicles. People say they can see satellites. I'm not going to argue if they can or not, but how do you know they are outside the atmosphere? I can go on with reasons why I believe this way and it may be fun doing so. But, if no one is interested than I can certainly understand. Thanks to those that participated.

I appreciate that. If in fact others do agree with me it would be very nice If they would offer support like you do. Some do but most don't. I can tell you one thing. The other side certainly does. Most of the time I create a thread I get a bunch from the other side lending support to each other trying to bring me down. I don't see much of that on the FE side. Really, the only one is you. It seems to me most REers believe what they are taught in school and they take it as being sacred or something. It simply don't believe it can be any other way. They try and explain the same thing that I can read on the internet. I know all that because I can read and comprehend. A lot of It just doesn't seem logical to me. They try and make it seem as simple as driving a car, but I know it can't be that simple. Just like you can watch the videos of people on board the ISS. I've watched tons of them and I can spot the obvious harnesses they wear under their clothing. Watch how the hair moves on the women. That can't be real. Their hair would not behave that way. They will stay on board for a year without taking showers or baths. The one lady astronaut, who had been on board for a year had said she actually asked the new arrivals if she stunk. Of course they said, Oh NO! I could go on and on. What is wrong with people, how can they believe this stuff. Most people I know don't give a damn about this stuff. They could care less, so they never care to pay attention. I think that is the way most people are. But, for those that do care and do pay attention, how in the world can they possibly believe it is real. To me it is like going to watch a 'Star Wars' movie and believing it is all real. I simply don't get it. Again, I do appreciate it when you step in and help me out when they gang up. I wish others would do the same. Of course you have Papa. He chewed me out because I was on his thread. Even though I was on his side. He, under no certain terms, wanted me fighting any of his battles for him. That brought me down a little. So, Maybe because of that, REers don't want other's support. It could be just me that does.

The indoctrinates support each other because they feel comfortable attacking and intimidating in numbers, little realising that they are actually following people that are doing this stuff by design. It's orchestrated with some of there so called indoctrinated global Earth theorists.
Most flat Earth or free thinkers don't jump in because there aren't too many for starters and those you think are flat Earther's are mainly piss takers on a mission.

The problem arises when someone like me jumps in as an extra back up to someone like you, or you aiding someone like me and then maybe Papa or legion may add extra weight. What happens?
They indoctrinates are made out to be pressing the complaint button wildly.
This leads to warnings for the bad free thinkers who are told about the rules and the given little irritating bans.

The only winners are the so called indoctrinated one's.
Unless you adhere to a flat Earth disc with UA and all the trimming's, then you are nothing to these these people and will be dealt with as mere fodder if you ever argue the toss with a group of so called global indocs.
Sounds crazy doesn't it as to why the many globals get away with 100 times worse crap towards free thinkers and yet a free thinker who questions stuff and has a dig at the posse; is banned or constantly warned.
It's about trust as well. As is, who to trust. For all you know, I could be here to muddy the waters and just add confusion but the same can be said of you and even Papa or a new mod who just appears after a year or so away and comes back too posting with moderator status and yet no mention of it anywhere on the forum for clarity.

What happened? a letter to the admin through pm or email just asking and getting the status.
It's laughable and it's about trust and who merits trust.
I'm not saying I don't trust you. You've been pretty consistent so I'm inclined to trust you as I do with legion and Papa.
There's one or two other's I trust but that's  about it.

Yeah it does seem obvious to you and to me and many other's. It really does beggar belief how a so called intelligent person can fall for this clear as day bullshit.
The reality is, top surgeons/doctors and such are conned every day by smooth talking roofers and window salesmen who ask for deposits for a deal. What happens is, they pay up and receive no work. Why?...Because they TRUST unconditionally because they've never experienced distrust.
Same with being told about amazing space feats. They simply accept them for how they're shown and told rather than look for obvious errors.




Watch how the hair moves on the women. That can't be real. Their hair would not behave that way.
It would if she had a perm or hair spray along with being harnessed upside down.
In all sensibility we can see it crap. We know that a woman would happily gop bald if they were so hell bent on being a so called space station commander/astronaut or whatever.
No way in hell would they be sent up to so called space into that electronic nightmare as well as a so called pressurised, air conditioned contraption, with a frigging hair do like they go up with.
I mean even the most gullible should understand that a shaved head means a wipe and no nightmare shampooing or attempts to mess with packaged water and such.
It's like telling a female surgeon in a theatre with long hair that it's not ok for that hair to dangle down  as she's doing the operation so she'd be better off applying stiffener to it so it points towards the ceiling, or she can wear a cap to cover it.

They take us for retards because they literally know that most of the world is asleep due to more pressing engagements, like material lives and worrying about what their neighbour is doing or buying.


They will stay on board for a year without taking showers or baths. The one lady astronaut, who had been on board for a year had said she actually asked the new arrivals if she stunk. Of course they said, Oh NO! I could go on and on.
Don't forget menstruation. We've seen video where good old Chris Hadfield tells us he can't cry in space because the tears won't fall. Imagine menstruation?
No so called gravity to rid the female of that monthly nightmare, eh?


What is wrong with people, how can they believe this stuff. Most people I know don't give a damn about this stuff. They could care less, so they never care to pay attention. I think that is the way most people are.
Correct, most people don't care for logical things as long as their lives appear to work for them.


But, for those that do care and do pay attention, how in the world can they possibly believe it is real. To me it is like going to watch a 'Star Wars' movie and believing it is all real. I simply don't get it.
The people that can see the bullshit like us, either talk about it amid a barrage of nastiness against the obvious or are too intimidated to bother to say anything and just sit there nodding quietly without creating any fuss.
There's many many people that see this stuff for the crap it is but very few speak out because they know it will change nothing unless it's done en masse. The trouble is, people have to have a reason to do that and it must be for their gain to be worthwhile.
A conspiracy nut is not something many people want to be known as and even more so in kn owing there is no gain for them other than ridicule because people who question official lines are already stamped as nutters and tin foil hat looney's.


Again, I do appreciate it when you step in and help me out when they gang up. I wish others would do the same. Of course you have Papa. He chewed me out because I was on his thread. Even though I was on his side. He, under no certain terms, wanted me fighting any of his battles for him. That brought me down a little. So, Maybe because of that, REers don't want other's support. It could be just me that does.
It's just about gaining a certain trust and because many of us have never really been involved much with each other, even in pm, then we tend to stand back a little bit to see how the land lies, kind of thing.

I appreciate that. If in fact others do agree with me it would be very nice If they would offer support like you do. Some do but most don't. I can tell you one thing. The other side certainly does. Most of the time I create a thread I get a bunch from the other side lending support to each other trying to bring me down. I don't see much of that on the FE side. Really, the only one is you.
The indoctrinates support each other because they feel comfortable attacking and intimidating in numbers, little realising that they are actually following people that are doing this stuff by design. It's orchestrated with some of there so called indoctrinated global Earth theorists.
Most flat Earth or free thinkers don't jump in because there aren't too many for starters and those you think are flat Earther's are mainly piss takers on a mission.

The problem arises when someone like me jumps in as an extra back up to someone like you, or you aiding someone like me and then maybe Papa or legion may add extra weight. What happens?
They indoctrinates are made out to be pressing the complaint button wildly.
This leads to warnings for the bad free thinkers who are told about the rules and the given little irritating bans.

The only winners are the so called indoctrinated one's.
Unless you adhere to a flat Earth disc with UA and all the trimming's, then you are nothing to these these people and will be dealt with as mere fodder if you ever argue the toss with a group of so called global indocs.
Sounds crazy doesn't it as to why the many globals get away with 100 times worse crap towards free thinkers and yet a free thinker who questions stuff and has a dig at the posse; is banned or constantly warned.
It's about trust as well. As is, who to trust. For all you know, I could be here to muddy the waters and just add confusion but the same can be said of you and even Papa or a new mod who just appears after a year or so away and comes back too posting with moderator status and yet no mention of it anywhere on the forum for clarity.

What happened? a letter to the admin through pm or email just asking and getting the status.
It's laughable and it's about trust and who merits trust.
I'm not saying I don't trust you. You've been pretty consistent so I'm inclined to trust you as I do with legion and Papa.
There's one or two other's I trust but that's  about it.


It seems to me most REers believe what they are taught in school and they take it as being sacred or something. It simply don't believe it can be any other way. They try and explain the same thing that I can read on the internet. I know all that because I can read and comprehend. A lot of It just doesn't seem logical to me. They try and make it seem as simple as driving a car, but I know it can't be that simple. Just like you can watch the videos of people on board the ISS.

You made a lot of excellent point that I never thought about before. I guess this website is more political than I realized and there is an agenda to be followed. I have often wondered why the women playing their parts on board the ISS movie didn't cut their hair short instead of using hair spray to keep it pointing up all the time. It would have made it look more real if they had. But no, they keep it long and it looks simply silly sticking up like it does. If I was the director I'd insist they cut it short to make it look more realistic. I hadn't thought about women's menstrual cycle before, that's much worse. They show a lot of videos of them playing with water. I know what water does inside a piece of electronic equipment. No big deal, right? Oh well, maybe it is just us wrong.

Of course, don't you know. If not I will explain.
An airplane is usually a long slender tube like vehicle with an engine of some sort and wings. To keep it simple, an engine provides the necessary inertia to keep it flying. The wings provide the means to defy gravity and give it movability. I know what you are getting at. You are trying to understand why I compare an airplane to a satellite. Let me simply say that I have seen many many airplanes flying around in the sky, taking off from the ground and landing on the ground. Infact, My last real job was the engineering manager in a company that designed and built UAVs. Most people call them drones, to us they were UAVs, Unmanned Air Vehicles. In fact the company was bought out by L3 communication. There site is below.
http://www.l-3com.com/ (http://www.l-3com.com/)

Now, I've told you what I've seen pertaining at airplanes, tell me how many satellites you've seen flying in space. I'm not talking about lights you've seen, I'm talking about real honest to goodness satellites. Sure there are some photo on the web, but are they real can you show me a real picture of an actual satellite in space? Your answer is probably none and that does not mean they don't exist. You would be correct saying that. But, how do you actually know they are free falling around the Earth in space and not simply circling the Earth because gravity is trying to pull them down but inertia is keeping that from happening like this below article says.
 http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/1-what-causes-an-orbit.html] [url]http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/1-what-causes-an-orbit.html (http://[url) [/url]
If you can imagine this is what is happening. Why can't it happen inside the Earth's atmosphere. We have gravity inside the atmosphere pulling down and inertia can be provided by engines on board a satellite and how do you really know that the satellite don't have control surfaces or wings. So my point is this. If this is all possible why can't a satellite be a flying device like an airplane that is simply flying around the Earth? I realize this notion goes against your grain, it did mine until I joined this website. Now, I don't really know what is real. I simply try and see the other side of things and if they could be real or not.

Attached to the wings are the elevators that give the airplane pitch. Pitch is when the nose of the plane goes up or down. When gravity tries to bring the plane down the elevators on the wing will cause the nose of the plane to lift. This is what I mean when I say wings defies gravity. does that agree with you?
Title: Re: Why do astronauts on board ISS float around
Post by: 29silhouette on December 22, 2015, 08:09:43 PM
Elevators are usually at the rear of the plane, and yes I agree they change the pitch.  If the wings fall off however, the elevators can try changing the pitch all they want, but the plane is still going to go down.

How do the wings provide the actual lift that lifts the plane off the ground and keeps it airborne?

Quite simply the purpose of the wing is to divert the air. The velocity of the diverted air depends on the speed of the wing and its angle of attack to the air. The amount of lift the wing provides depends on how much air it diverts and the speed of the wing. Any airplane besides a glider needs power to provide lift. Is this what you are looking for?

No, I mean inertia. The meaning of inertia is: Inertia is the tendency of objects to keep moving in a straight line at constant velocity. The engine is what gives an airplane the constant velocity. Thrust is push (something or someone) suddenly or violently in the specified direction. I'm not talking about suddenly pushing the airplane violently because that would change velocity.

 Yes, the wings will provide lift. If not for lift, gravity will cause the airplane to fall. thus, the wings defy gravity. I should not have to explain that to you.

Engines provide thrust, not inertia.  Inertia is an property inherent to all physical objects, nothing needs to "provide" it.  The definition of thrust has nothing to do with levels of "violence" or how "suddenly" it occurs.

As a rule, I don't throw cheap shots at people only when someone throws them at me. For example you did this first, "For someone who was apparently some kind of engineer, you do seem to get awfully confused about the basics." I'd call that a cheap shot, and you used it against me first. Then yes, I did come back at you in a mild marrer sort of way. I have never done that to someone on here that hasn't done that to me first. I wouldn't call it whining when I simply ask people to try and be civil. I'm not mentioning names, but a lot of people on both sides try and bully others and that usually leads to name calling and a lot then get discouraged and are never heard from again. I don't like to see that happen. I enjoy expressing my opinion to you, alpha, 29silhouette and all the others that participate on this thread and I wouldn't want that to change. Enough said about this.

Jimmy,  I was referring to this website:
http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/1-what-causes-an-orbit.html   (http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/1-what-causes-an-orbit.html)
Basically I was referring to this from the article, "These forces of inertia and gravity have to be perfectly balanced for an orbit to happen."
My thoughts are, why does a satellite have to be in space orbiting the Earth in the first place? The way I look at it, a satellite can be inside the Earths atmosphere doing the same thing as a satellite orbiting the Earth. To me a satellite is really no different than an airplane or an airplane can do the same thing as a satellite. That is when I brought up gravity works on an airplane the same as a satellite and the engine will provide the inertia to overcome the pull of gravity. I know that the engine provides thrust to get the airplane moving and wings provide the lift to get the airplane off the ground, but once the plane is at altitude and at a certain cruising speed, the engine provides the inertia to keep the airplane going in a straight path and the wings are defying gravity by providing lift to keep the plane from falling to the ground. That is all I was trying to bring out in the debate. Why can't, what we call satellites, be no more than airplanes flying around in the sky? The U.S. has many military planes flying all the time. Why can't they be GPS satellites? NASA still uses U2 airplanes. Why can't tropospheric scatter be used instead of geosynchronous satellites. Most people think that most communications with other countries are through the use of satellites, But there not, most communications are done with submarine underwater cables. The general public is not privy to all that goes on in this world. Few knew that we had a stealth jet fighter, until they rolled out the F-117. 

I know that people like yourself don't want to think about it that way because you believe in space travel. So, it is your job to shoot as many holes in my ideas as you can and it is my job to try and defend them. I just don't like it when the belittling begins.

Basically I was referring to this from the article, "These forces of inertia and gravity have to be perfectly balanced for an orbit to happen."

As I think you might have noted, "inertia" is not a "force".  That statement could have been better worded as "The centrifugal force and gravity have to be perfectly balanced for an orbit to happen."  Still a bit inexact.


My thoughts are, why does a satellite have to be in space orbiting the Earth in the first place? The way I look at it, a satellite can be inside the Earths atmosphere doing the same thing as a satellite orbiting the Earth. To me a satellite is really no different than an airplane or an airplane can do the same thing as a satellite.

There is really only one reason why  a satellite has to be in space.  The Lockheed SR-71 Blackbird had a service ceiling of 85,000'.  Even at its maximum speed of 2,200+ mph there were massive problems with heating from atmospheric friction.  At this altitude a satellite would have to travel at about 17600 mph to stay in orbit, ie for centrifugal force to match gravity.
There would be two insurmountable problems arising from this:
1) The massive atmospheric drag would rapidly slow the satellite down, and
2) This drag would heat the satellite to well over red heat!
The satellite has to be high enough to keep the atmospheric drag to acceptable levels.  Even the ISS at 200 miles or so has to be boosted back to a higher orbit periodically - using fuel that has to be resupplied.
 
That is when I brought up gravity works on an airplane the same as a satellite and the engine will provide the inertia to overcome the pull of gravity. I know that the engine provides thrust to get the airplane moving and wings provide the lift to get the airplane off the ground, but once the plane is at altitude and at a certain cruising speed, the engine provides the inertia to keep the airplane going in a straight path and the wings are defying gravity by providing lift to keep the plane from falling to the ground. That is all I was trying to bring out in the debate.
In steady flight he engine does not provide "inertia", but thrust to overcome drag due both to air friction and component of lift directed to the back (the wing's lift is not purely vertical, but almost normal to the wing).

Why can't, what we call satellites, be no more than airplanes flying around in the sky? The U.S. has many military planes flying all the time. Why can't they be GPS satellites? NASA still uses U2 airplanes. Why can't tropospheric scatter be used instead of geosynchronous satellites. Most people think that most communications with other countries are through the use of satellites, But there not, most communications are done with submarine underwater cables. The general public is not privy to all that goes on in this world. Few knew that we had a stealth jet fighter, until they rolled out the F-117. 

I know that people like yourself don't want to think about it that way because you believe in space travel. So, it is your job to shoot as many holes in my ideas as you can and it is my job to try and defend them. I just don't like it when the belittling begins.
While it might be possible to provide some of these services with high flying aircraft, there would need to be thousands flying all the time over the whole earth.  These aircraft would have to be refueled regularly from bases all over the earth!
In addition to this the provision of GPS services would require the location of the aircraft known to metre accuracy, and how would that be done without GPS?
Tropospheric scattering cannot explain satellite TV at a fixed location high over the equator.

True, most communications is via undersea fibreoptic cables, but satellite services are needed to mobile locations, eg ships at sea, travellers in remote areas (outback Australia, Sahara etc) etc.
(Have to go, hope there are not too many errors!)

When I was growing up it was centrifugal force that caused objects to move outwards. Like centrifugal clutches and the weights in a distributor would move outwards to advance the timing. Then I started reading that centrifugal force was not a real force at all it was really centripetal force. So, I thought I'd study this a little deeper. That is when I got on the subject of satellites in orbit. I read the following:

Velocity, Acceleration and Force Vectors
The motion of an orbiting satellite can be described by the same motion characteristics as any object in circular motion. The velocity of the satellite would be directed tangent to the circle at every point along its path. The acceleration of the satellite would be directed towards the center of the circle - towards the central body that it is orbiting. And this acceleration is caused by a net force that is directed inwards in the same direction as the acceleration. This centripetal force is supplied by gravity - the force that universally acts at a distance between any two objects that have mass. Were it not for this force, the satellite in motion would continue in motion at the same speed and in the same direction. It would follow its inertial, straight-line path. Like any projectile, gravity alone influences the satellite's trajectory such that it always falls below its straight-line, inertial path. They demonstrated this with the following image:
(http://i.imgur.com/dlM1536.jpg)

This picture shows an object following a path around the Earth at a precise distance above the Earth because inertia is causing the object to fly straight and gravity wants to pull the object down to Earth. What you have is a nice curve flight around the Earth. Well, if this is the case, then isn't this the same thing airplanes do.
No, it's not.

An airplane's forward motion is much too low for this to work. The dashed blue lines in the illustration would be far shorter for an airplane, but the green inward-pointing arrows would be the same size, so it wouldn't follow the red circular path; it would intercept the Earth.
 
Quote
They fly around the Earth everyday. The airplane's engine is providing the inertia to cause the airplane to fly forward and gravity is trying to pull the airplane down.
No, the engine is providing thrust, which is necessary to overcome drag from air resistance. The wings provide lift, which is necessary to overcome weight, which is due to gravity.

Quote
The pilot has to maintain altitude and direction and a nice curved path is maintained around the Earth just like a satellite does. It is really a balancing act between gravity and inertia. Gravity is trying to pull it down, but inertia keeps it from happening.
No, if thrust equals drag and lift equals weight, the airplane flies at a constant altitude and speed. More generally, the vector sum of thrust, drag, lift and weight determines whether the aircraft gains or loses altitude, speeds up or slows down; if they sum to zero, it has no altitude change and maintains speed.

Quote
If the airplane's engine stops, gravity will take over and it will free fall to the ground.
No, it will glide to the ground, which isn't free fall, because the wings provide some lift if they're moving forward. With the loss of thrust, drag will reduce speed, which reduces lift, so weight exceeds lift and the aircraft loses altitude.

Quote
If the satellite's inertia runs out, then the satellite will free fall to the ground.
Yes. But what would cause this?

As it is, because there is a very tenuous atmosphere even at the heights most satellites orbit, they do lose a little energy (and momentum) colliding with these particles, and their orbits do decay unless additional energy is supplied, usually in the form of a rocket engine in some form. This is a very slow process until the satellites get very low (for a satellite), however.

Quote
In this case, the only real difference between a satellite and an airplane is how high each fly.
Nope. They are completely different.

Quote
What I don't understand is why do all the videos show the astronauts floating around inside the ISS. To me that is no more possible than passengers on an airplane floating around inside the airplane. We all know that doesn't happen.
Not true... stay tuned.

Quote
Some say it is because the ISS is in free fall and it is like being on an free falling elevator.
They're right, too!

Quote
That can't be true because inertia is what keeps satellites and airplanes from free falling to the ground in the first place.
Satellites are in free-fall. Because their forward motion is high, the ground is falling away at the same rate, though. Airplanes stay aloft because of lift generated (mostly) by the wings, which causes drag, which must be overcome by thrust. They are not is free fall when flying normally.

--> An example of an airplane in free fall is the "Vomit Comet", whose passengers do float around inside the airplane

Quote
Others say they float around because there is no gravity in space. That is not true, there is only 10% less gravity on the ISS then on Earth and that is not enough difference to keep passengers on an airplane from floating around.
You are correct. Zero gravity is a misconception and does cause some confusion. Passengers in an orbiting spacecraft are in the same orbit as the spacecraft they're in, and both are in free fall, so there is nothing resisting the acceleration of gravity toward the center of the Earth, so they feel no weight. Gravity is very much in effect.

Quote
So, I sit here and wonder if the videos of the ISS true, false or I'm I totally off base on my reasoning?
The first and last are correct.

Perfect Reasoning and good science!

You are wrong.
We have proved how a satellite wold be in free fall by moving fast enough to fall around the globe, the speeds required for the altitude are given.

There are plenty of sources giving its exact position in real time.
The ISS can be observed from the ground. Its position predictable with math.
You can see it through practically any telescope.
I stress, there are many apps and websites available that detail its position at any time.
watch it pass over with your eyes.
There are videos from on board showing what life wold look like there is no gravity. 

ISS exists, and you can prove it for yourself.

Because they are in gravitational equilibrium; orbit.

There are also objects not in gravitational equilibrium; proof of that can be obseved every day on Earth; meteors a.k.a. falling stars.

There's nothing else; orbit or crashing.

Objects can be caught in orbit from desequilibrium; Phobos and Deimos have experienced just that and are now orbiting Mars.

There is only 1 force in space; gravity. The equilibrium is between different gravitational fields.

Just like a magnetic object can be in equilibrium between different magnetic fields.

but magnetic forces can either be repulsive or attractive.
gravitational forces are only attractive.
gravity depend on mass, but in the solar system there's no object with a mass similar to the sun, how can there be a gravitational force able to contrast the one produced by the sun?

So the ISS is in a permanent state of free fall , its forward velocity is fast enough the it is falling at the same rate as the curvature of earth is falling away from it. the Astronauts on board experience this as a lack of gravity. (like the Vomit Commit)

It's because everything inside that object is traveling at the same speed than the object... When inside the ISS you travel at the same speed as the ISS, in other words the same forces (inertia and gravity) will apply to you.

When you open the door of the ISS and get out you will then travel alongside the ISS. If you slow down the ISS with a rocket it won't affect you but the ISS will fall behind and start to decent to earth. You will carry on in your trajectory.

If you were inside the ISS when it slowed down you will slow down as well.

When your car accelerates you accelerate along with it

Trust me, I'm trying hard to see the logic in this, so please bear with me.
How doe the ISS travel that fast? Everyone on here has told me that inertia is not a force. So the only force acting on the ISS, that I can see, is the force of gravity. I would think the ISS has to be in free fall towards the center of Earth because the definition of gravity is the force that attracts a body toward the center of the Earth. Traveling 17,150 mph, it will take 52 seconds to hit the ground. And somehow it misses the Earth and goes around it? in order to go around it, wouldn't it have to be pulled at an angle towards the side of the Earth and not pulled towards the center? Explain that please.

The ISS has motion or inertia, when an object moves in a certain direction the only way to change the speed or direction is to apply a force to it. The ISS has very, very little atmospheric friction to slow it down and as such don't need a constant force propelling it.

An airplane needs engines with thrust pushing it continuously, burning a lot of fuel to keep it in constant motion because the atmosphere tries to hold it back.

In space there is little or no atmosphere and as such it's possible to propel an object to a very high speed and when that speed has been reached you need very little if anything to keep it at that speed. That is why the ISS doesn't burn up, harldly and resistance up there

The ISS was accelerated to 17000mph with rockets when it was put into orbit. (a much smaller part back then that has been added to as it is modular). The ISS is falling to earth at the same rate that the earhs sphere is falling away from it, so no altitude is lost.

* Added for accuracy, but not needed for understanding the principal.
(The small amount of atmosphere dose slow the ISS so occasionally they fire a booster to speed it back up and gain altitude. This event can be observed on many websites dedicated to tracking the ISS)

How doe the ISS travel that fast?
The rockets that accelerated the parts into that orbit.

Everyone on here has told me that inertia is not a force. So the only force acting on the ISS, that I can see, is the force of gravity. I would think the ISS has to be in free fall towards the center of Earth because the definition of gravity is the force that attracts a body toward the center of the Earth. Traveling 17,150 mph, it will take 52 seconds to hit the ground. And somehow it misses the Earth and goes around it? in order to go around it, wouldn't it have to be pulled at an angle towards the side of the Earth and not pulled towards the center? Explain that please.
It's moving 17,150 mph parallel with the surface of the planet while being pulled down, therefore it keeps missing the planet.  Look at your own links and pictures you keep posting.

Oh I love science fiction.

But I don't forget the second word; "fiction".

I embrace science as well; after all I am a scientist.

Hence my focus; separating the science from the fiction.

Many years ago airplanes and self driven cars were science fiction, if the designers of cars and airplanes had your mindset then we wouldn't have had cars and airplanes
The science and engineering of airplanes and self-driven cars make sense. Both from and engineering and scientific standpoint.

The space fantasies only make sense in the same way that Santa Claus makes sense; "we want it to be true, so it must be true". Unfortunately; I was very disappointed to learn it can only be fake(d).

To answer getrealzommb, No it doesn't. on line it say that the floating is because of free fall, as if they are on an elevator or the vomit comet.

Back to 29silhouette, You are telling that the ISS is traveling 17,500 mph parallel with the earth and gravity is trying to pull it down. And That causes free fall.

Yendor imagine you are standing on a earth with no atmosphere... and you drop a ball from your hand... It will fall directly down.

If you throw that same ball softly it will travel a couple of meter before it will hit the ground.

The harder you throw it the further it will travel before it will hit the ground.

Now imagine you throw that ball at 17 000 mph then you will throw the ball over the edge of the earth (The Horizon), in other words the ball will travel so fast that it will never reach the ground, and as the earth is round at will just keep on falling over the horizon. With no atmosphere to cause friction and slow the ball down, it will just keep on going for ever.

The ISS is like the ball that you threw, they just used rockets to propel it so fast.

I see the insults are coming out and trust me, I understand what everyone is saying, I've read what  everyone has mentioned many times. I've tried to find the reason why object actually float on board the ISS and I can't. Mostly I find is that they are in free fall. I just want someone to explain why when they show the videos of the ISS everyone is floating and the women's hair is standing straight up and it looks unnatural as hell. They are all floating around as if they are falling slower than the ISS is falling. I was under the understanding that objects in space fall at the same rate. It is not obvious to me that that is true on the ISS because it looks like the spacecraft is actually falling faster than the objects inside and they never seem to catch up. I would expect to see them simply walking around normal. The gravity is only about 10% less, so it can't be that. I don't see the astronauts falling slower than the ISS when they are outside tethered to the craft. They seem to be falling at the same rate or the tether would be tight. It always seem to be loose. When I'm on an elevator and as it starts to go down I feel as if the floor drops out from underneath my feet, but as soon as my body catches up I don't feel it any longer. I would just expect the ISS to be the same way. I don't want anyone to get mad and start chunking more insults towards me, but this is the way I see it and I simply don't understand. If no one has an answer then please don't bother with this thread and I'll just live with it.

They are falling at an identical rate, therefor equal, hence they look to float in equilibrium with their surroundings and have to hook their feet into loops in order to not rotate due to the slightest muscle movement causing momentum.

Gravity has not changed. Its not 10% less its just 99.9% ineffective upon the astronauts everything in orbit with them.

When you go on an elevator you are only descending at less than 1 meter per second hence why you catch back up and feel no different. If the elevator could keep accelerating downwards to terminal velocity (56 meters per second), you would experience weightlessness, just as on ISS

So... In our solar system which is a planet with a mass able to produce a gravitational field that opposes to sun's ones and makes orbits possible?

Ill try to answer the original question, first do you understand how orbits work, if not learn it from a quick google search.
Second, to be in orbit, the iss has a fast velocity perpendicular to the surface, all people inside have the same velocity. Both the people and the iss are accelerating downwards at the same speed, since both the iss and people have the same acceleration and velocity, they will both follow the same path. If you had an astronaut outside the iss moving at the same velocity as an astronaut inside, he to would follow the iss as well.
A plane is different, consider a plane flying at a constant speed, there is a force from the wings countering gravity, so the plane has no acceleration, but the people inside still accelerate downwards, so the acceleration acting on the plane and people is different, so the people inside the plane move downwards to it's floor.

There was a lot of activity on here after I left last night. I appreciate everyone's thoughts on this subject. I especially want to thank legion because he came to my rescue and defended me. I know everyone is trying to relate me to a child because you all believe what you've been taught and it makes all the sense in the world to you. But to me, not so much. I've been taught the same as most on here but I have a little difficulty believing it.

From what I've gathered, it is the free falling that causes the astronauts to float around inside the ISS. Even though they are falling the same speed. I don't believe this is true. I'm going to attempt to give my reasoning and I hope I can explain it well enough for everyone to understand.

Picture the ISS located at the equator at the very middle of the earth. The earth's diameter is around 8000 miles. That means you are 4000 miles from the edge. The ISS has to travel parallel with the earth for around 14 minutes before it reaches the edge of the earth. The ISS is around 250 mile above the Earth, but it is only around 188 miles from the Kármán line before it starts to enter the earth's atmosphere. If gravity pulls the ISS down, it would only take 38 seconds before it starts to enter earth's atmosphere. Since gravity is the only force acting on the ISS to cause it to go into free fall, it couldn't be in free fall very long and it has to keep traveling parallel to the earth to keep from being pulled to earth. The vision everyone has is that this great big ISS just falls around this little ball earth and everyone is okay with that. My vision is this tiny ISS is flying around this great big earth. To me, it is traveling parallel with the earth all the time and maybe a slight bit of gravity is pulling it so they would have to use rocket thrust to bring it back up over time. But it is not free falling at all. You can watch the videos of the ISS and I don't see it free falling. It is flying parallel and level with the earth just like an airplane would fly around the earth only faster. I'm sure everyone on here has heard or used the story of traveling in an airplane traveling 600 mph and you don't feel the movement at all because you are traveling the same speed as the airplane. Well I use that same argument here. The ISS traveling 17,000 mph and the passengers will not notice it either because they are traveling the same speed as the ISS. That is my reasoning and I hope you can understand what I'm trying to say. You can call it childish thinking if you want, but to me it seems logical and I'm not a child.

Post by: getrealzommb on December 27, 2015, 09:04:53 AM
There was a lot of activity on here after I left last night. I appreciate everyone's thoughts on this subject. I especially want to thank legion because he came to my rescue and defended me. I know everyone is trying to relate me to a child because you all believe what you've been taught and it makes all the sense in the world to you. But to me, not so much. I've been taught the same as most on here but I have a little difficulty believing it.

From what I've gathered, it is the free falling that causes the astronauts to float around inside the ISS. Even though they are falling the same speed. I don't believe this is true. I'm going to attempt to give my reasoning and I hope I can explain it well enough for everyone to understand.

Picture the ISS located at the equator at the very middle of the earth. The earth's diameter is around 8000 miles. That means you are 4000 miles from the edge. The ISS has to travel parallel with the earth for around 14 minutes before it reaches the edge of the earth. The ISS is around 250 mile above the Earth, but it is only around 188 miles from the Kármán line before it starts to enter the earth's atmosphere. If gravity pulls the ISS down, it would only take 38 seconds before it starts to enter earth's atmosphere. Since gravity is the only force acting on the ISS to cause it to go into free fall, it couldn't be in free fall very long and it has to keep traveling parallel to the earth to keep from being pulled to earth. The vision everyone has is that this great big ISS just falls around this little ball earth and everyone is okay with that. My vision is this tiny ISS is flying around this great big earth. To me, it is traveling parallel with the earth all the time and maybe a slight bit of gravity is pulling it so they would have to use rocket thrust to bring it back up over time. But it is not free falling at all. You can watch the videos of the ISS and I don't see it free falling. It is flying parallel and level with the earth just like an airplane would fly around the earth only faster. I'm sure everyone on here has heard or used the story of traveling in an airplane traveling 600 mph and you don't feel the movement at all because you are traveling the same speed as the airplane. Well I use that same argument here. The ISS traveling 17,000 mph and the passengers will not notice it either because they are traveling the same speed as the ISS. That is my reasoning and I hope you can understand what I'm trying to say. You can call it childish thinking if you want, but to me it seems logical and I'm not a child.

I have little hope for you.

I waded back through the thread. I count 7 decent full explanations on how orbit  is acieved and 4 on why that makes astronauts appear to float around complete with links to at least 2 videos. In some posts to the math to calculate such feats of witchcraft are put forth.

You thank Legion, because he appears to share your floored logic and lack of intellect, but he is in fact making a mockery of you. He himself can provide you with a reason on why its not possible to float around on the ISS can he? has he got the facts and figures to prove it? No! Hes just a troll.

I give up on trying to explain facts to someone who doesn't think that facts are believable.

The motion of objects is governed by Newton's laws. FACT

As I said, the astronauts are at the same velocity as the iss, and will have the same acceleration towards the center of the earth as the iss, so since they share the same acceleration and velocity, the astronaut follows the same path as the iss. Hence the astronaut stays stationary relative to the iss, so he floats relative to it.

I hate to say it but, you guys have a lot of book smarts, but little common sense. Or you could figure this out on your own and not have to rely on NASA telling you lies and making a mockery of you. I feel sorry for you because you can't think on your own. Even when I show you what orbit is you still don't understand. There is no free fall in orbit, so why do they float around? If, like in an airplane it is traveling in a straight line the passengers won't feel movement and they certainly won't float out of their seats. Wake up folks and think about it. It is not hard at all. Have you ever seen any videos of the ISS going up and down like the 'vomit comet'. No, it always flies straight and parallel with the earth. This notion they fall around the earth is science fiction and plain old BS and you guys lap it up. When I started this thread and asked the question, "Why do astronauts on board ISS float around", I knew that no one could figure out the lie. You all have proved me right.

P.S.
Legion, I believe this is a win for flat earth.

There's a valid reason why Yendor is puzzled by the actions of this supposed ISS and its supposed orbit around a supposed globe. The reason is because he's intelligent enough to see bullshit when it rears its ugly head so blatantly.
Then you get the globalites jumping on him and trying their best to make him appear child like when they know for a fact that he's questioning because it BEGS questions, which is why Legion is backing him up, because Legion and many other logical people who possess common sense can see that the official explanations are clear and utter made up magical fantasies.

Falling around the Earth for crying out loud.  ::)

This centrifugal that is now not a force and is centripetal force that isn't a force unless it becomes a force when people start to question, yet manages to exert a force onto a so called space craft by is counteracted by another force that isn't actually a force unless questioned constantly, which then turns back into a sort of force that we simply just don't understand.

Imagine that?
Imagine trying to explain that from scratch to people who haven't been brainwashed.

A defiance of genuine physics. When you see a wall of death motorcycle stunt person going around and around, you don't wonder why he's not flying into the crowd outside   because you can see that his motorbike tyres are pushing against a barrier and that barrier is resisting that push.

Imagine that motorbike going super fast around a ball. What force could seriously pull it into the ball as opposed to stopping it shooting outwards in a straight line?

This centripetal force supposedly acts upon the ISS in space as if it's a swing ball machine and the ISS is the ball attached to the string as it's whizzing around the pole.
It doesn't fly off because of the string. The very same string that is bullshit gravity.
This invisible string force where the ISS just wants to piss off into space but good old gravity string says, "not on your Nelly Mr, you're on a leash."

Centripetal force and gravity allow the ISS to simply fall around Earth.  ::)

Ok all you scientific minded people. All those who possess the logic and common sense. I have an experiment you can do that will show you how much bullshit this is.

The tools you need are thus:

A lid from a jar that has a lip so it can hold a few small plastic beads.
A few small plastic beads.
A hand held battery operated face fan. A £ store or a $ store one.
A glue stick gun or some strong glue.

Oh and the main thing you need is a small vacuum chamber that will hold the fan and accessories.

Ok here's what you do.

You take the fan blade from the fan and pierce a tiny hole in the jar lid. You then push it firmly onto the fan shaft and glue the back and front so that the lid is stuck to the shaft.
You now glue the fan bottom to the bell jar vacuum base as close to the centre as you can and allow it to dry so it cannot fall over.
You put a few beads in the inside of the rim of the jar lid and switch it on.
You will find that your centripetal force is keeping the beads stuck to the rim, because it's basically like the motorbike wall of death, only this is vertical but same thing.

It's also how they tell you that the ISS is doing its  rounds in space.

Now here's the key.
Place your bell jar over the base with the working fan motor and jar lid plus beads spinning like crazy and start evacuating the pressure from that jar.

This is where you see your ISS fall from space to the bottom of the bell jar base, because centripetal force has now been rendered useless.
You see, the beads no longer adhere to the rim because it only works with atmospheric pressure and cannot and does not work without it.

Now all you genuine thinkers that want the truth, don't take my word for it, go and try it out for yourself.
If you have a chamber then the rest will cost you  £1 or a $1.

I'll see if anyone is willing to try this and if they are then it should clarify one hell of a lot to them.

Why would there be acceleration? If both are the same speed why do they depict people and everything else floating? They should not float until they go free falling towards the earth and I never see that happening unless they purposely want to.

I just gave you an answer, both the iss and the astronauts have the same speed and acceleration, so there is no relative motion between an astronaut and the iss.

Why would there be acceleration? If both are the same speed why do they depict people and everything else floating? They should not float until they go free falling towards the earth and I never see that happening unless they purposely want to.
The confusion here seems to be "free fall". If by free fall you mean falling straight down to earth, then the astronauts are not in freefall, personally I think freefall is the wrong word for the situation.
Ill separate my argument into sections, tell me which one you don't agree with.
1. To be floating in the iss, an astronaut has to be not moving relative to the iss when he is not trying to move and is not touching any walls.
Freefall is one way of this happening but in this case it isn't
2. The acceleration is caused by gravity, and acceleration due to gravity is the same for all objects in a vacuum. So both the astronaut and the iss have the same acceleration and velocity.
3. Since the astronaut and iss have the same velocity and acceleration, they will follow the same path.
4. Since they follow the same path, there will be no relative movement between the iss and the astronaut.
Combine 1 and 4, and you have a floating astronaut.

I think 1 is the one you don't get.
If you think a person in a plane is also going at the same speed and acceleration, there is a difference.  A plane a person has to be touching the floor to not be falling, because the plane is generating lift to counter gravity, so a person has to be on the floor to be effected by the lift. On the iss this isn't the case, the iss is not producing any force, the only force effecting the system is gravity, which effects the astronaut where or not he is touching a wall.
Edit: reading what you have said I want to ask you something, what do you define floating as.

Videos show the folks and objects to be floating when they are not tied down or holding on.

2. The acceleration is caused by gravity, and acceleration due to gravity is the same for all objects in a vacuum. So both the astronaut and the iss have the same acceleration and velocity.

Okay

3. Since the astronaut and iss have the same velocity and acceleration, they will follow the same path.

Okay

4. Since they follow the same path, there will be no relative movement between the iss and the astronaut.

Okay

Combine 1 and 4, and you have a floating astronaut.

Here is the problem I have. NASA says the astronauts are floating in space because of free fall and they even demonstrate this with the vomit comet. They say the ISS or any satellite simply falls around the earth. and because of that the objects are weightless and they float around. You have to be smart enough to know that any object coming under the influence of so called gravity is going to fall to earth unless it has a way to defy gravity. Even if the ISS or an airplane is flying, gravity will bring it down if it has no lift to keep it defying gravity. I don't see the ISS having wings.

To me, floating is when you are not under the influence of gravity or lighter than air.

Ok, that is because I was only looking at the force of gravity, the main force in the situation. If gravity was the only force there would be no relative motion, when you include the astronaut pushing off from surfaces and the force from the air inside the station hitting his body you will have him moving relative to the station. I defined floating badly; I'll give a better one.
Floating="When there is no permanent force pushing you against a surface.”
I hope this definition makes more sense, on earth we don’t float because we have a force pushing us down, so we can’t float up, and the friction from being pushed to the ground stops us from floating forwards, backwards, left and right. Same on a plane, the plane is staying at a constant height, and you are still going downwards because of gravity, so you are pushed against a surface again.

Now I think you have said you understand orbits, you just don’t consider them as free falling because they don’t go down. On the vomit comet you float because both you and the plane are being affected by gravity and nothing else, this causes you to not be pushed against any surface of the plane. Now in the ISS isn’t falling as in moving downwards, but it is accelerating downwards, so it’s not “free falling”, more “free accelerating”. It’s the “free accelerating” that causes things to float, since it means objects within it will not be pushed to one surface. If you think you would be pushed towards one surface of the ISIS, which one, down, up, backwards, and why.

Now I think you have said you understand orbits, you just don’t consider them as free falling because they don’t go down. On the vomit comet you float because both you and the plane are being affected by gravity and nothing else, this causes you to not be pushed against any surface of the plane. Now in the ISS isn’t falling as in moving downwards, but it is accelerating downwards, so it’s not “free falling”, more “free accelerating”. It’s the “free accelerating” that causes things to float, since it means objects within it will not be pushed to one surface. If you think you would be pushed towards one surface of the ISIS, which one, down, up, backwards, and why.


I hate to say it, but you have me a little confused here. It sounds like, again, you are saying gravity is not enough force to push them down. There is gravity, almost as much as on earth. Why would they float if they push off something?

I understand what they mean by orbit. I understand that forward motion is counteracting gravity and the object will travel around the earth. You say that the object is free accelerating towards the earth and that is causing things to float. What happened to the forward motion of the object trying to prevent that from happening. It would hit the atmosphere in only 38 seconds. If what you say is true, then they would have to constantly fire the rockets to overcome the gravity.

No, you obviously don't understand what they mean by orbit.  Forward motion does not counteract gravity.  Gravity is always pulling the ISS downwards.  The forward speed simply ensures that the ISS misses the earth.

Just because they are aimed at children; that doesn't make them true. Only a complete idiot would suggest that. And that you believe these videos knowing that they were "designed for children"!

How embarrassing. For YOU.
Yep. You're right. This was the very next post.

But legion is known for just tossing stuff like this in from time to time, so most of us are used to it by now and take it for what it's worth[nb]Approximately nothing.[/nb].

trust me, I understand what everyone is saying,
That doesn't seem so clear. Based on what you write here, you don't understand it at all.

Quote
I've read what  everyone has mentioned many times. I've tried to find the reason why object actually float on board the ISS and I can't. Mostly I find is that they are in free fall. I just want someone to explain why when they show the videos of the ISS everyone is floating and the women's hair is standing straight up and it looks unnatural as hell.
They are in free-fall and it isn't natural for people to be in that environment.

Quote
They are all floating around as if they are falling slower than the ISS is falling.
Why do you think this? If they were falling slower than the ISS is falling, they'd all be pinned to the ceiling[nb]The "ceiling" in this case is the part farthest from earth.[/nb]. But they're floating around, which is what you object to, which means they're not pinned to the ceiling.

Quote
I was under the understanding that objects in space fall at the same rate.
All objects in space don't necessarily "fall" at the same rate, they accelerate at the same rate[nb]If they are at the same distance from the center of the Earth, in this context.[/nb]. "Falling" at the same rate means they also have the same velocity, which isn't necessarily true in all cases. Objects in the same orbit do fall at the same rate at the same point in the orbit. Objects contained within another object in orbit do meet those conditions.

Quote
It is not obvious to me that that is true on the ISS because it looks like the spacecraft is actually falling faster than the objects inside and they never seem to catch up. I would expect to see them simply walking around normal.
Wait... if the spacecraft were always falling faster than the objects inside, unattached objects inside would be pushed against the side opposite the direction of fall. Are you seeing this? Obviously not, since you're complaining that the pictures show astronauts floating around inside it. So, how, exactly, does it "look" like this is happening? If that were happening, you would see them walking around normally, on the ceiling. Can you clarify what it is you're trying to say here because this makes no sense.

Quote
The gravity is only about 10% less, so it can't be that. I don't see the astronauts falling slower than the ISS when they are outside tethered to the craft. They seem to be falling at the same rate or the tether would be tight. It always seem to be loose.
The acceleration of gravity, regardless of what the exact value is, is the same for both because they are at the same distance from the Earth. In this case they are falling at the same rate, so there's no net velocity between them except when the astronaut outside accelerates to maneuver around. So what you see is exactly what would be expected. Why would you expect otherwise?

Quote
When I'm on an elevator and as it starts to go down I feel as if the floor drops out from underneath my feet, but as soon as my body catches up I don't feel it any longer.
The elevator accelerates downward from a stop for a few moments, then moves downward at a constant speed. You feel the floor drop as it accelerates, then your weight returns to normal when the acceleration stops and the downward velocity becomes constant.  This is high-school physics stuff. Consider you claim to have had a career in engineering (http://www.theflatearthsociety.org/forum/index.php?topic=65151.msg1740566;topicseen#msg1740566), this is pretty disturbing since it's really, really basic and very well understood.

The relevant part of that linked post, near the middle of the last paragraph:
Quote
I'm a very technical person. I've spent nearly my whole life working as an electrical engineer. I've even designed products that were supposedly used on satellites.

Quote
I would just expect the ISS to be the same way. I don't want anyone to get mad and start chunking more insults towards me, but this is the way I see it and I simply don't understand.
Here are what I think are the possibilities. These aren't meant to be insults, just the possibilities based on what you say here:

1) You're willing to play the foil, pretending to be ignorant, and encouraging people to present facts in a very easy to understand way. Well done! <imagine thumbs-up emoji here>

2) You just enjoy posting stuff to see what response you can elicit. Still <thumbs up>, because it elicited a lot of easy to understand explanations for anyone casually reading.

3) You really don't understand how this works, and are "exaggerating" that career in engineering. <thumbs down>, but see comment after 2), above.

4) You really don't understand how this works, but somehow managed to have a career in engineering anyway. (Yikes!   :o )

5) You used to be a brilliant (or at least competent) engineer and used to understand how this works but don't any more.  :'( [nb]This happened to my mother-in-law; she was a very good engineer, and excellent at explaining engineering problems, until her last years; it was very sad and distressing to watch it happen.[/nb]

Ok, that is because I was only looking at the force of gravity, the main force in the situation. If gravity was the only force there would be no relative motion, when you include the astronaut pushing off from surfaces and the force from the air inside the station hitting his body you will have him moving relative to the station. I defined floating badly; I'll give a better one.
Floating="When there is no permanent force pushing you against a surface.”
I hope this definition makes more sense, on earth we don’t float because we have a force pushing us down, so we can’t float up, and the friction from being pushed to the ground stops us from floating forwards, backwards, left and right. Same on a plane, the plane is staying at a constant height, and you are still going downwards because of gravity, so you are pushed against a surface again.
Quote
Here is the problem I have. NASA says the astronauts are floating in space because of free fall and they even demonstrate this with the vomit comet. They say the ISS or any satellite simply falls around the earth. and because of that the objects are weightless and they float around. You have to be smart enough to know that any object coming under the influence of so called gravity is going to fall to earth unless it has a way to defy gravity. Even if the ISS or an airplane is flying, gravity will bring it down if it has no lift to keep it defying gravity. I don't see the ISS having wings.
Now I think you have said you understand orbits, you just don’t consider them as free falling because they don’t go down. On the vomit comet you float because both you and the plane are being affected by gravity and nothing else, this causes you to not be pushed against any surface of the plane. Now in the ISS isn’t falling as in moving downwards, but it is accelerating downwards, so it’s not “free falling”, more “free accelerating”. It’s the “free accelerating” that causes things to float, since it means objects within it will not be pushed to one surface. If you think you would be pushed towards one surface of the ISIS, which one, down, up, backwards, and why.


I hate to say it, but you have me a little confused here. It sounds like, again, you are saying gravity is not enough force to push them down. There is gravity, almost as much as on earth. Why would they float if they push off something?

I understand what they mean by orbit. I understand that forward motion is counteracting gravity and the object will travel around the earth. You say that the object is free accelerating towards the earth and that is causing things to float. What happened to the forward motion of the object trying to prevent that from happening. It would hit the atmosphere in only 38 seconds. If what you say is true, then they would have to constantly fire the rockets to overcome the gravity.

You need to understand  circular motion. Acceleration and velocity are different things, F=ma not F=mv, an object can be accelerating downwards and keep a parallel velocity, the velocity doesn't counteract acceleration, because it doesn't, they are different things.  People never feel velocity, only accelation. Of cause you feel the air when you have velocity relative to the ground but that is not the same thing.

You plonker Rodney, I have explained to you all you really need to consider is Gravity Constant, Altitude and Orbital Velocity. All of  of which are identical for the ISS and the astronauts.. That Equals Equilibrium.

The astronauts are in the same frame of reference.

The  Orbital Velocity (orbital period of about 88 minutes) of  the ISS and Its crew has to be quick enough (7.66 km/s) through the very Low density atmosphere that it is traveling forwards (7.66 km/s) and falling (Gravity's effect 9.8 m/s^2) at the same rate as the Earth Curves away from it. (0.20m/km.)
The chosen Altitude for the ISS orbit was 400km above Sea Level.
The Earth is 40,075.16 kilometers round the Equator.


Test the theory,
Show me your workings
Lets find out why you believe the ISS would crash. (it would without occasional boosting)

I'm saying only that I linked a page describing centripetal force.  Do try to avoid putting words in my mouth.

the page linked says the force is orthogonal to the motion.

The way I've seen it described is when you accelerate in a straight line the force is forwards but you feel pushed back in your seat.  Similarly when turning in a circle you feel pushed to the outside but the force is opposite towards the center.

The cloths are forced by the tub to turn inward the same as centrifugal. A ball on a string twirling over your head is centrifugal force pushing the outwards.

No, centripetal force is in all of those examples as the inwards acceleration that causes the object to turn. The centrifugal force only appears in the reference frame of the object, take an ant standing on the ball, it would fell an outwards centrifugal force.

If the ant is on the ball as it spins round he would feel an outward force and it would be called centrifugal force. In that case the ones inside and outside the ISS are feeling centrifugal force as well.

The cloths are forced by the tub to turn inward the same as centrifugal.
The force of the tub wall causing the clothes to turn inward is centripetal.

Quote
A ball on a string twirling over your head is centrifugal force pushing the outwards.
Nothing is trying to push the ball outward, it's merely trying to travel in a straight path, which would be away from the center of it's circular path. 

Quote
If i let out some more string the ball will take up the slack and move further out.
As the centripetal force is lessened, yes the ball will move further out as it tries to go straight momentarily.

Quote
If when I let out more string the ball came closer to the center, that would be the opposite to  centrifugal force, centripetal force.
How would the ball come closer by letting out more string?  The centripetal force is what is making the ball follow it's circular path.  Pulling the string in would make the ball come closer to center.

Quote
Show me something that works like that.
A ball on a string.  Centripetal force makes it turn instead of going straight.

Or, do you want to see something that, when centripetal force is lessened or removed, curves inward even more instead of straightening out?

Okay, I believe we are on the right track about this. Let me show you what I found on the internet.

A piece of string with ball attached to one of the ends is held firmly by the hand. An impulse or motion is imparted to the ball by the hand, that motion being continued by the movement from the hand. The first impulse given to the ball by the hand represents the Primitive Impulse. The tension on the string which holds the ball to its controlling centre represents the Centripetal Force, while the opposite force on the string, which takes up the Primitive Impulse and continues it, is represented by the Centrifugal Force.

In other words, a ball with a string attached hanging from your hand by the string is the Centripetal Force because the string is putting a force on the ball to keep it in the center or in your hand in this case. Now when you give the string and ball motion and the ball twirls around over your head that is Centrifugal Force because it is a force pulling the ball away from the center or your hand in this case. The string is supplying the Centripetal Force and the ball twirling is supplying the Centrifugal Force. These two forces work exactly opposite each other.

Now, I can understand this.

So the reason why astronauts float in space is due to centripetal/centrifugal? force or falling around the Earth at super speed?

Would this be right and if so, what else can make astronauts float in space?

Basically, yes. They have no net motion relative to nearby objects because they're all traveling and accelerating in the same direction at the same rate.

Maybe you can tell me why the Apollo astronauts were floating inside their craft when out of Earth's so called orbit?

Also as an added extra, how did the so called Apollo craft actually fly to the so called moon when it wasn't orbiting Earth and was on a supposed straight trajectory towards the so called moon, meaning it had no means to float and can't have used propulsion.

Now before you go into this, " an object in motion will stay in motion until acted upon by an opposite force" you have to tell me how this craft floated, bearing in mind that there is no up/down/side to side in so called space and is a so called vacuum or nothingness.

Let's see what you can come back with before I proceed.

I'll give you an answer. The other side probably can't use Google.

This is for Apollo 11.
The TLI burn began silently. But as the acceleration load went from zero to 1.5 Gs, our cabin began to shake. The Pacific tilted beneath us. Six minutes later, the burn stopped as abruptly as it had started, and my limbs began to rise once more in weightlessness. McCandless said the TLI burn had been excellent. We were travelling at a speed of 35,570 feet per second and were passing through 177 nautical miles above Earth. "Looks like you are well on your way now," he added.

Ok thanks, Yendor.
So basically the craft was travelling at 25,000 mph in 1969. Hmmmm.

I wonder if  anyone can tell me how they managed to slingshot the craft out to take a trajectory to the moon?
I was always under the impression that a person on Earth, or a plane or helicopter when they jump up, fly or hover, will still be carried by Earth's spin.

So given that thought, it stands to reason that a rocket craft separation that has just went into a 25,000 mph orbit is going to stay in that orbit unless it hits something that can change it's trajectory.
What that something is I'd like to know.

Obviously it cannot use brakes to slow down and then  about turn to go on a moon course, can it?
I honestly can't see how it manages this, let alone manages to go 25,000 mph in 1969 but I'm not too bothered about the speed, just the miraculous trans lunar injection thing, whatever that really is.


Anyway, brakes or slingshot or whatever? Tell me, anyone.
Title: Re: Why do astronauts on board ISS float around
Post by: Mainframes on January 08, 2016, 12:58:21 PM
Neither brake or slingshot.

If you accelerate in orbit your orbit increases in size. All you do is increase speed until your orbit intersects the path of the moon.

Who says they weren't in orbit around the Earth while en route to the Moon between trans-lunar injection and lunar orbit insertion? And it wasn't a straight trajectory; the trans-lunar injection burn put them in a highly-elliptical orbit, still with the Earth at one focus, but its apogee beyond the Moon's orbit. They used propulsion (the third stage engine was restarted) to change from the nearly circular low-earth orbit into the highly-elliptical trans-lunar one. During the "burn" (which supplies the force necessary to change the state of motion), they weren't floating. See Buzz Aldrin's quote (although not so designated) in Yendor's post (http://www.theflatearthsociety.org/forum/index.php?topic=65151.msg1746685#msg1746685) above.

Now before you go into this, " an object in motion will stay in motion until acted upon by an opposite force"
I think you mean:
Quote from: http://csep10.phys.utk.edu/astr161/lect/history/newton3laws.html
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Nothing about "opposite" in that. You must be conflating Newton's First Law of Motion with the Third.

Quote

I don't have to tell you anything. I will answer in the remote hope that you'll learn something useful, and for anyone else who is interested.

What's to tell? It's following an elliptical trajectory that is designed so the craft will arrive in the vicinity of the Moon a little "ahead" of the Moon in its orbit. What do human perceptions of "up", "down", etc. have to do with this? As far as I know, they were navigating using ECI (Earth-Centered Inertial) coordinates, and didn't use those terms.

17,000 mi/hr sounds about right, why?

If Yendor's quote is accurate, the TLI burn accelerated them to a bit more than twice about half again that speed.

The Apollo 11 was in Low earth orbit at 17,300 miles per hour for a few orbits then while over the Pacific ocean, the Saturn V rocket's third stage had to burn without stop for almost six minutes to reach 24,500 mph — escape velocity.
That gave them the  The Apollo 11 the boost needed to push the  into a new orbit that intersected with the moon. Once nearing the moon the Saturn 5 was once again steered, this time into lunar orbit.

Neil Armstrong is quoted as saying. "Hey, Houston, the Saturn V gave us a magnificent ride." about this part of the journey.

S-IVB, the third stage of a Saturn-V rocket.

That's also correct, but bear in mind that the speed decreases as the distance from earth increases, as it must for a Keplerian orbit. In the case of Apollo, the things that could change its trajectory were the gravitational field of the Moon and the rocket motors it carried.

Quote

Why "slow down and then about turn"? That costs energy. They accelerated from the trajectory they were already in to a new one with the desired properties. 

Quote

The Saturn-V third stage contained a really powerful rocket engine (https://en.wikipedia.org/wiki/Rocketdyne_J-2). They could build those in 1969 despite your incredulity.

Quote

Since you think they had to stop and turn around to make that happen, it's no wonder it looks like a miracle to you. Fortunately, they had people who knew how to do this.

Neither. Acceleration using a rocket. The concept isn't difficult, as Mainframes already explained.

Right in the simplest terms I can....

sceptimatic, I am sorry to inform you but your mental age is possibly quite a bit less than your physical age. You show a degree of mental deficiency that quite frankly is disturbing. If some people refer to you as a moron, its OK that just means "a person of subnormal intelligence "  some people may also call you a half-wit, idiot, imbecile, retard, simpleton or even a mong "a person suffering from Down syndrome", that's OK to.

Help is at hand.

Search google (you can ask a friend to help you) for your local Special needs school for adults, and enroll yourself for a year long intellect booster course. You will learn many new concepts in a way that is simple to learn with many visual aids.  This may even help you to seek and find employment.

In about a year, come back to this thread and we might be able to explain things again. You may then have the foundations in place to understand these simple physical concepts and even be able to read through your prior posts and understand what a dunce you once were.

Good luck,
I'm rooting for you.

This mean they can't play, because to explain it in simple terms would to explain it in simple terms, which means that they make themselves look less than convincing in trying to show the magic of this amazing space rocket trajectory change.

Let me give you all a helping hand into what I'm talking about so you get the real insight.

When we argue about their spinning ball Earth and tell them that helicopters hovering above Earth's floor, do not notice any Earth rotation under them.
We get told that the reason for this is that the helicopter ios rotating at the same speed as the Earth and when it hovers, the atmosphere still carries it with the Earth at the same speed so we notice  nothing.

Of course we know that's preposterous but they have a silly argument for that by telling you that you can jump up in a plane or train whilst it's moving and you don't go flying off. Crazy I know but there you go.

Ok let them have that.
What about their rocket in orbit as Gene Cernan mentioned. It orbited about one and a half times around the Earth at 25,000 mph and then sling shots out towards the moon.

The problem is, I'm told it's not a sling shot or a snapped centripetal imaginary string or a braking system to deflect it towards the moon.

The trouble is they won't actually tell me in simple terms just what it is.
You see, this rocket is apparently spinning around the Earth in space. Like a super fast supposed satellite.

How does the rocket  go to the moon?

An object in motion (rocket) will stay in motion until acted upon by an external force. It could also be deflected by an external force but stay in motion. You know, like a space snooker white ball hitting a colour.
That could deflect the space rocket to the moon, eh?...maybe not because deflecting is a bad idea for destroying stuff as we seen in the film, gravity.


So what's to be done to get to this moon?
Apparently what happens (if they explained to me correctly) is that the rocket actually keeps orbiting the Earth and gets wider and wider with this orbit. A sort of - imagine drawing a ball and drawing a circle around it, then spiral outward so you have lot's and lot's of rings around the ball until you reach another ball (moon) and then spiral around that but only a singular circle as you orbit this.

Imagine doing this all the way to the moon at supposedly 240,000 miles away, just orbiting wider and wider and yet never falling back to Earth but always managing to spiral outward and then slowing down when you reach the moon, somehow.

Maybe that's not exactly how it works. I can't be certain if this is what the space scientists proposed happened because there doesn't seem to be any on here that can explain it by using a very simple analogy for how it happened.


Can anyone remember seeing the NASA Earth/moon trajectory  PENIS diagram that Papa Legba put up.
It was really funny at the time but it showed how they supposedly went to the moon.
What it didn't show was what was explained to me.
It showed an orbit and then a straight trajectory to the moon and around the moon , then back in a straight trajectory to Earth.

If anyone can find this diagram I'd appreciate it, because this diagram indicates a sling shot to the moon and the experts on here have already told us that it wasn't a sling shot.

Confusing isn't it?

Obviously it's not confusing to the experts on here who will no doubt call me a retard and  what not, as if that actually answers the questions.  ;D

Sceptimatic - the swing ball is an analogy. Learn what that means. There is no literal string.

The string represents the force of gravity ( or acceleration due to gravity if we want to be exact). If there are any other forces acting on the spacecraft then the net force will determine the acceleration and in what direction. Simple case of of vector mathematics.

So when the rocket engine is fired an additional force is imparted on the rocket (in addition to gravity). This additional force in the case of TLI was used to accelerate the orbital speed creating an elliptical orbit that had its apogee intersecting the moons orbit.

I'd still like to know how the moon astronauts floated inside their space ship on the way to the moon. How did they float and for what reason?

On the way to the moon the forces that are acting on the spacecraft are exactly the same as those acting on the astronauts. Therefore they will be accelerating in exactly the same direction and magnitude as the spacecraft. This means that the astronauts will be free to float inside.

Nothing about this is hard.

Apollo was in orbit around the earth. The trans lunar injection pushed the spacecraft into an elliptical orbit that intersects the moon.
Well let's see if we can clear a few things up.
I recall Gene Cernan mention that they orbited the Earth about one and a half times, then off on a trajectory towards the moon.
Ok, I can accept this bit for the sake of it.
How fast was the orbit around the Earth for that one and a half times?...any idea?
Pretty dam fast, but the whole "object in motion remains in motion" thing means that you don't feel velocity, only acceleration.

There really isn't a force that causes the astronauts to float. It just that there is no relative acceleration between them and the ship. When the engines are on they aren't weightless, because the ship is then accelerating.

Think about it this way, when you jump out of a plane with weighing scales at your feet, your weight will be zero, because you are accelerating downwards at the same rate as the scales.
Now imagine an astronaut in the iss with scales. He puts the scales at his feet, again because both the person and the scales are accelerating at the same rate, he weighs nothing.
If anyone doesn't understand, say which way the astronaut should weight, should he weigh downwards(towards earth), forwards (direction the iss is going), or backwards or upwards.

Post by: Empirical on January 09, 2016, 06:05:15 AM
And about how the rocket gets to the moon, it changes it's orbit to be an ellipse around the earth the intersects with the moon.
And did someone say that a helicopter hovering should be moving because it's no longer rotating with the earth, do you know what inertia is?

Yeah; that's a 'clamp'?

So it's SUSPENDED FROM the gantry, then?

Not what you originally said is it, Walt?

You said it was CLAMPED TO the gantry...


Have you never seen a gantry crane before?    They are used for lifting and moving things...  Can you see it now? 
Oh, so it's a gantry-CRANE now?

Again; not what was originally stated...

So now, rather than being CLAMPED TO THE GANTRY, it's SUSPENDED FROM THE GANTRY-CRANE...

The story-telling evolves!

And yes, I do see it; flimsy thing ain't it?.

And I also see your multi-billion dollar shpayze-ship is slung from that ONE flimsy beam by at most TWO cables.

So ONE failure anywhere in the system would result in disaster.

Not much redundancy there, eh?

Could NASA not afford a more secure attachment system?

Or did they not care, because it is a stage-prop?

Pathetic...

Oh, & 'Empirical'; stop double-shitposting, eh?

Although its a game I think some flat Earthers would benefit from playing kerbal space program to understand how orbital mechanics work. They have applied they same physics that earth has on the fake planet Kerbin such as gravity, different levels of atmosphere, lift vs drag, ect. Its a great learning experience and funny while you learn.
Explain how the Apollo crew managed to do this with their craft. This appears to look like a sling shot. Tell me how this was managed.

How about you explain how they managed to do this.

*Sigh*

Managed to do what? We've already gone over the getting to the Moon part. The rest is similar; they fire a rocket motor to change from one orbit to another.

The TLI burn of the S-IVB put the craft in an elliptical orbit that intersects the Moon's orbit (lower left part of your diagram).  As it nears the Moon, this orbit is perturbed by the Moon's gravity; for the early Apollo lunar missions, the orbit was designed so that, after passing the Moon, if nothing was done, the new orbit, after being influenced by the Moon's gravity, would return the craft to the Earth along a favorable trajectory - the free-return trajectory[nb]The calculations necessary to design this are not trivial, but could be done, even using "only" the computing power available in the '60s.[/nb]. As it was, a Lunar Orbit Injection burn of the Command Module's main engine was accomplished, which altered the orbit enough so that the craft entered an elliptical orbit about the Moon (larger loop, lower right), clockwise in the diagram then another burn to maneuver into the desired low circular orbit (the smaller loop inside larger loop around the Moon, still at lower right).

A few days later, the craft is still orbiting the Moon (still clockwise, of course, at upper right in this drawing), after the Moon moved partway around its orbit around the Earth while at the same time the CM is orbiting the Moon. The diagram is showing the location of the Moon at approximate times of arrival and departure, but not the time between; is that confusing you?

The CM's main engine is fired again to accelerate the craft away from the Moon (upper right, just below the Moon in the drawing) and into an orbit that intercepts the Earth's outer atmosphere (left, above earth in the drawing), which slows the craft as it passes around the planet until it is traveling slow enough to deploy parachutes and make a soft landing in the ocean (far left of the drawing).

In addition, the diagram shows the lander's path from lunar orbit to the surface and back.

Keep in mind that the drawing is schematic; it isn't to scale.

Does that help?

I have a question that I don't know the answer to. Maybe one of you space cowboys can answer it for me. NASA say,"Once in Earth orbit, the last stage of the Saturn rocket fires, boosting the Apollo spacecraft and its three-man crew into its flight trajectory to the moon." Okay they fire the last stage of a big rocket to put them into flight trajectory to the moon. My question is, how come when they leave the moon's orbit they don't need to fire a big rocket to put them into flight trajectory to the earth. NASA says,"Upon return to Earth, the command and service modules separate, leaving the command module to plunge into the Earth's atmosphere at a velocity of 25,000 mph." I've looked at the command and service module and I don't see anything that looks like the last stage of a Saturn rocket. Wouldn't they need the same power to get to earth as it does to get to the moon? Another thing, Look a the command module, how does that thing enter the earth's atmosphere perfectly with the shield pointing down and not tumbling every which way and not burning up?

The part of any space fight that takes the most energy is getting into low earth orbit, getting back to earth is controlled falling.

The amount of fuel needed increases exponentially with distance, the simple reason is that as you add more fuel, the rocket get heavier so you get less distance out of the fuel. So halving the distance reduces the fuel needed by a lot more than a half.
So when your returning from the moon, the rocket weights a lot less, and when returning to earth you have gravity on your side, so you don't need a very large engine.

And someone mentioned Kerbal Space Program, a lot things aren't realistic (it is a game) but it is correct on how orbits work.
I you want to know how space ships get to the moon, download the demo. It uses the patched conic approximation if anyone wants to know how it works.

Video showing how you get to the mun in the game.


And to answer the question, once the rocket is in a circular orbit, it burns prograde to make it's orbit path elliptical and intersect with the moons orbit, when the rocket gets near the moon it is captured by the moons gravity, the rocket then burns retrograde so that is slows down so it goes into a  circular orbit of the moon.

They do need a big rocket (https://en.wikipedia.org/wiki/Apollo_Command/Service_Module#Service_Propulsion_System), just not nearly as big as the one that got them there.

It doesn't have to be as big for two reasons:

1. It takes less thrust to accelerate a given mass away from the Moon than from the Earth because the Moon is much less massive.

2. The CSM's engine doesn't have to accelerate nearly as much mass as the S-IVB had to. At TLI, the S-IVB's J-2 engine had to lift the Command Module with three astronauts and provisions for more than a week, the fully-fueled Service Module, and the fully-fueled LM with its tools, fuel, and supplies and the S-IVB stage itself with a partial fuel load. When leaving lunar orbit, the Service Propulsion System (the CSM's AJ-10 engine) had to lift the Command Module with three astronauts and provisions for three days plus a few hundred pounds of samples, and the Service Module with its partially-depleted fuel supply (probably about half at the start of the insertion burn, but that's a guess). Everything else was left behind or consumed.

It may be small compared to a J-2, but that's still a pretty honkin' big rocket compared to the size of the craft it's bolted to.

Quote
Wouldn't they need the same power to get to earth as it does to get to the moon?
Nope. See above.

According to Wikipedia, the SM's AJ10-137 engine has about 9% as much thrust as the S-IVB's J-2 engine (91 kN vs 1001 kN).

Another thing, Look a the command module, how does that thing enter the earth's atmosphere perfectly with the shield pointing down and not tumbling every which way and not burning up?
Careful design, planning, and execution. They had very good rocket scientists and aerospace engineers working on it, and a well-trained crew aboard.

This is the insides of the service module. I don't see much in the line of fuel. So, you are saying that once it leaves the moon the inertia will carry it 238,900 mi. to earth and how do they steer this thing towards earth? It doesn't show any rockets to steer it by.
(http://i.imgur.com/47L5Hqk.jpg)

Careful design, planning, and execution. They had very good rocket scientists and aerospace engineers working on it, and a well-trained crew aboard.

But what keeps it from wobbling when it enters earth's atmosphere. It stays at the perfect angle as it is coming in and the shield is hot enough to melt butter and then it deploys parachutes for a soft landing in the water and then it deploys a tubular life raft around the thing to keep it from sinking. Like this picture shows.
 (http://i.imgur.com/ChoV3Ex.jpg)
My question is, where do they keep this inflatable raft so it doesn't get burned up? You can see it is attached right at the part that is going to get pretty darn hot.

No scientists will say that rockets get to the moon by sling shot. Once the ship is in low earth orbit, it accelerates prograde, this changes the orbit path to an ellipse, which intersects with the orbit of the moon.
How about, in nice simple easy for a child to understand, words, you explain how this prograde acceleration works to sling shot/alter/manoeuvre this spacecraft so that it takes a virtual straight trajectory to the moon like in that penis and balls diagram that NASA are literally taking the piss with.

No silliness and expecting people know the mumbo jumbo. Just explain what happens.

I'll try and help you out in how best to explain.

I'm whizzing around the wall of death on my motorbike. I'm accelerating, then all of a sudden an obstacle protrudes from the side wall and I deflect off of it with my bike. I deflect up and out of the wall of death container and into the air.
If there was a dangling moon above me, you could say I hit it.

Let's say I'm playing swing ball. I keep batting the ball on the string, faster and faster until the string snaps. My ball then launches into a straight line from wherever it snapped.


I'm using atmosphere from which you have none, other than this gravity/centripetal force kind of thing and a weak moon gravity as we get told.

You're fine to call me as many names as you want to but at least explain this magic for me.
Prograde acceleration that takes a craft out of orbit and near straight as a dick to the moon.
Title: Re: Why do astronauts on board ISS float around
Post by: Empirical on January 09, 2016, 03:56:02 PM
When did I call you names, your the one resorting to profanity.
And I can't explain  it simply enough for a child, it is fairly compacted.
In the picture that path isn't a straight line, its an elliptical curve.
Conics curves are circles, ellipses, parabolas and hyperbolas. The path of an orbit will always be one of these curves, with a focus if the curve being the position of the planet. The prove of this is to complex for me to put here, if you want to argue this point look up the maths behind it and try and find something wrong with it.
When the ship is going in a circle path, it accelerates in the direction it is going, this causes the orbit path to change from a circle to an ellipse, the ship has to accelerate at the right time and amount so that the ellipse orbit will go past the moon. When the ship gets to the moon, it slows down relative to the moon, so that it starts orbiting it.

So what you're saying is, the spaceship slingshot's outwards upon acceleration but in doing so it's like a baseball pitcher throwing a sort of curve ball towards the bat?

Basically you''re saying that I can swing a ball (spaceship) around my head and then let go so it arc's into the air and comes back down behind a football 50 yards away?

What snaps the string on acceleration for it to do this bendy trajectory?
Who put's the pitcher curve on it to do this deed?

Here's where the problem lies. Think about this.
If that space  ship is WHIZZING around the Earth at 25,000 mph as it accelerated, then even if it widened it's orbit, it would still be whizzing around the Earth in a wider orbit all the time and could not just do a 240,000 mile bendy curve ball behind the moon trick.

How in the hell are you people believing this crap?
Title: Re: Why do astronauts on board ISS float around
Post by: Empirical on January 09, 2016, 04:18:38 PM
Its nothing like a baseball pitcher, because a baseball will always have gravity pulling it in the same direction. The ship with have the direction of gravity changing as it moves.
And a string isn't a proper analogy, the string stops an object getting any futher than a set distance, gravity doesn't do that.
When it goes between the moon and the earth it is still in an orbit, and elliptical one.

The circle around the earth is a circular orbit, the path between the earth and moon is a section of an elliptical curve around the earth, untill near the moon, when the rocket changes it's trajectory to a elliptic orbit around the moon, which is then stabilized to a circular orbit around the moon.

You think you're 'explaining' things, but you're just stringing words together.

It's pretty sad.

You may as well say: 'Santa accelerates to every house in his Sleigh, stops via a retrograde reindeer-burn, climbs down the chimney, eats milk & cookies & leaves presents, depending on who's been Naughty or Nice, then re-climbs the chimney, accelerates his sleigh again via a booster reindeer burn, and repeats the process until all presents are delivered'.

Forget around the moon. I want to know about the slight bend in the penis before we even reach the balls.
I need to know how the rocket does a one and a half turn around the bell end to then bend along the shaft on the penis to the moon balls.

That is how the real world works. The world works in simple ways. It's just made into gobbledegook so people cannot fathom just how simple it is.

The bullshit is what keeps the elites from the downtrodden. The tricksters who ask you which cup the ball is in and show you how easy it is to pick, until you pick the empty cup.
Manipulation and sleight of hand.
Stand back and take your time to decipher the bullshit then the sleight of hand and you start to see the pattern.

If you want 1+1 to equal 2 then have a reason for it to do that. If you find that 1+1 does not equal 2 according to a physics professor, then ask yourself if there's a physical end product to that calculation. If you find there is only a theory as an end product, then discard it and stick to the reality which can be physically calculated.

This is the insides of the service module. I don't see much in the line of fuel.
They don't need a lot. The SPS engine only burns for a few minutes.

Two of the four fuel tanks are sketched in outline in that drawing so you can see the helium tanks behind them. The arrow labeled FUEL STORAGE TANK points near the bottom of one, FUEL SUMP TANK points at the bottom of the other. There are two more like them on the other side.

Here's a another interior view. The two large cylinders are the SPS fuel tanks.
(http://www.spaceacts.com/apollo%2013_pressure_mystery_files/image002.jpg)

Quote
So, you are saying that once it leaves the moon the inertia will carry it 238,900 mi. to earth
Essentially, yes. The engine doesn't need to fire continuously to keep moving. In fact, it speeds up as it approaches closer and closer to earth. It's falling toward earth, remember?

Quote
and how do they steer this thing towards earth?
If they start out in the correct trajectory, they will arrive at the desired point. This is accomplished by burning the SPS for the correct amount of time in the correct direction at the proper place in the orbit around the Moon. Errors in the initial trajectory are adjusted by making midcourse corrections along the way - generally short burns in a calculated direction at a calculated spot.

Quote
It doesn't show any rockets to steer it by.
(http://i.imgur.com/47L5Hqk.jpg)
Yeah it does. Each RCS Quad has four small rockets (hence "quad"), and there are four of these quads [IIRC] spaced evenly around the outside of the SM that are used to orient the craft in space by firing in specific directions in combinations.

Quote
Careful design, planning, and execution. They had very good rocket scientists and aerospace engineers working on it, and a well-trained crew aboard.

But what keeps it from wobbling when it enters earth's atmosphere. It stays at the perfect angle as it is coming in
There's a whole branch of aerodynamics called "blunt body dynamics" that has the answers to this question. Apparently a body shaped like this will tend to remain oriented flat side first, but this is far from my field of expertise. You're the aerospace guy. Look it up and you tell us.

and the shield is hot enough to melt butter and then it deploys parachutes for a soft landing in the water and then it deploys a tubular life raft around the thing to keep it from sinking. Like this picture shows.

My question is, where do they keep this inflatable raft so it doesn't get burned up? You can see it is attached right at the part that is going to get pretty darn hot.
Presumably behind the heat shield which, IIRC, is jettisoned after the parachutes open. You're good at Google. I'm sure you can find it.

In rabinoz's defense, it's hard to tell if you're being facetious or not, given many of the astonishingly wrong things you often say here. Are all the outrageously wrong things you say here in jest, only the wildly understated ones, or some of either or both?

It will get tedious asking (and reading) "are you kidding?" before replies to wacky assertions from you, so please give us some guidelines so we can assess when you're just kidding and when you're not, or something like a winky-face emoji when you're being facetious; that's what they were invented for.

Maybe you missed the earlier answer (http://www.theflatearthsociety.org/forum/index.php?topic=65151.msg1746894#msg1746894). Here's the "good part", in case you don't recognize it:
The TLI burn of the S-IVB put the craft in an elliptical orbit that intersects the Moon's orbit (lower left part of your diagram).  As it nears the Moon, this orbit is perturbed by the Moon's gravity
Now, you may think the word "perturbed" is worth a giggle - who knows - but it has a specific meaning that refers to orbits being affected by the presence of other objects, and has nothing to do with genitalia or sex[nb]Sorry![/nb].

At any rate, it means that the presence of the (rather substantial) mass of the Moon affects the orbit of the Apollo spacecraft substantially when it's in the vicinity of the Moon. You can't just "forget around moon". Reality doesn't work that way.

Quote
If you can't do it then that's fine. If no one else can, then that's fine again because it means there's a good reason. It means the so called science behind it all, is bullshit.
Perhaps, or, more likely, you simply don't, or refuse to, understand he answers you get. Not being able to help you understand may be inadequate explanations, or it may be your problem. There's nothing anybody by but you can do about the latter.

Nice try, though.

The only reason why many things are made so complicated to understand for people is because the populace has to be separated into classes so the slaves can be repetitive in serving the masters and are bred to DO - not to think.

Things are only difficult depending on who is explaining or showing you.
The major issue with most people is the fact that they dare not accept simplicity in understanding because they fear it makes them appear to stand out as backward when confronted with a person who has memorised the complicated  bullshit that takes them around the perimeter rather than through the clear shortcut.
That's your so called science world.

Your rocket science is exactly the same. It's not rocket science, is a term used to make out something is easy whilst rocket science is deemed scientifically complicated in it's set up.
A rocket is simple in reality but complicated when the bullshit of space gets involved.

Wow.  What utter hogwash.  The reason that many thing are made so complicated to understand is because the closer you look, the more complicated they are.  For example, in principle, starting a car's engine is very simple -  turn the key and it starts.  But what's happening when you turn the key?  Well, turning the key turns activates a whole sequence of events that need to happen in order to start the engine.  If you look deeper, each of those events requires more things to happen and so on.  Most people don't really care what happens when they turn the key so long as the engine starts.  Does that mean that they're slaves to the auto industry masters?

Same thing with floating in orbit.  The principle is fairly simple, but the closer you look, the more complexity you run into.

The concept of a rocket is simplicity in itself and one of the easiest examples of newtons 3rd and conservation of momentum you could possibly see. Space makes things very simple as the forces involved are straight forward. Orbital mechanics can be a little trickier though.

Rockets get complicated when you build them in reality due to the engineering requirements of fuel supply, guidance and materials.

You open the box to see thousands of little jigsaw pieces.

You decide to find the 4 corners and all the straight edge borders. Then you look for the most stand out colours.

There's also a reason why basic logic outweighs basic bullshit. There's a reason why simplistic reasoning far outweighs nonsensical fantasy.

The only reason why many things are made so complicated to understand for people is because the populace has to be separated into classes so the slaves can be repetitive in serving the masters and are bred to DO - not to think.
Wow.  What utter hogwash.  The reason that many thing are made so complicated to understand is because the closer you look, the more complicated they are.  For example, in principle, starting a car's engine is very simple -  turn the key and it starts.  But what's happening when you turn the key?  Well, turning the key turns activates a whole sequence of events that need to happen in order to start the engine.  If you look deeper, each of those events requires more things to happen and so on.  Most people don't really care what happens when they turn the key so long as the engine starts.  Does that mean that they're slaves to the auto industry masters?

Same thing with floating in orbit.  The principle is fairly simple, but the closer you look, the more complexity you run into.
You get a large 10,000 piece jigsaw. You see a picture on the front of the box. It looks a nice picture. It's a picture of a Porsche.
You open the box to see thousands of little jigsaw pieces.
It now looks daunting. Too many pieces to put together.

You decide to find the 4 corners and all the straight edge borders. Then you look for the most stand out colours.
Before long you have built the jigsaw from bottom up.

Do that with science and things start to look more simple and can be explained in a simple way that can re-start the logic of the most stubborn indoctrinated/ignorant mind.

Perhaps you ought to try that then.

I suggest you go forth and build some jigsaws then, because you are well and truly indoctrinated by FE trolls. You talk a load of bollox but it just dosn't have the jizz

Already have. It works. It allows your mind to see past the bullshit.

A jigsaw puzzle is just one level of complexity.  Many things that science deals with have several levels of complexity.

Take a car, for example.

At first glance you have a car that you can get in and drive just fine.

Then you look under the hood and see the engine, transmission, suspension and other major components.

Look at the engine and you will see that the engine has cylinders, pistons, fuel injectors, and so on.

Look at a piston and you will see that it is made of a special alloy of metals that has been precision machined to optimize performance.

See, layers of complexity.

Of course. If you read between the lines, it's exactly what I'm saying and it's down to breaking everything right down to the bare bones and realising that there is a simplicity about all of it. The major issue is when that simplicity is shrouded in secrecy and mystery.
Instead of making things easier for people, they sling them a curve ball in certain circumstances if it can further an agenda.

In this case it's space craft of all descriptions from probes to rockets to stations to satellites and so on.
Take the shuttle bi-pod bolt. You wonder how a bolt can be so strong to hold this mammoth machine to a tank and wonder what metal it's made of.
Apparently it's unobtanium.

They might as well tell us it's made of rocking horse shit.

Rather than wonder, why not look it up?

What are the specs?

Even if they've quit making new ones, there may still be some NOS in storage somewhere.

Is that more suitable for this application than unicorn feces?

At any rate, if you care, you could probably find out. If you don't care, what's your point?
