uh oh. another nail. sorry guys.

And what is the alleged value of g on the silly fake ISS then?

In metres per second squared, please.

Spam it up and we'll do the math on it, eh?

I guarantee the math will state that it must be travelling at billions of miles per hour by now...

Off you go!

At 400 km altitude g = 8.6822 m/s².

Your turn.
What tangential speed at that altitude and that g is required to counter the weight of the ISS ?

EDIT: Earth radius - 6371 km, which makes ISS trajectory radius 6 771 km, or 6 771 000 m.

Back on topic, i.e. the rabbibot's madness:

You seem to have made the topic, "Gravity forces things down", so back to that:

When you can't even explain why gravity doesn't force the moon down to crash into the earth - after all the moon is a satellite of the earth.
What an ignorant loser!

So it looks like Papa Legba's still the ignorant loser!

You can't even explain what holds the moon up or why this stupid Papa Legarian gravity doesn't force all planes to crash,
since you claim that gravity forces things down!

Okay, so the silly fake ISS is being accelerated by gravity at nearly 20 mph every second it is in orbit.

There are over 31 million seconds in a year.

And the ISS was first put in orbit 20 years ago.

So, multiply 31 million by 20 by 20 and you'll have the number in miles per hour that gravity will have accelerated the silly fake ISS up to by now...

I get it in the tens of billions.

This is not debatable btw, which is why you've gone into mad AI shitpost frenzy mode trying to cover it up.

Because my post conclusively proved that the ISS cannot be orbiting the earth.

No you didn't!
The ISS is able to orbit the earth in exactly the same way that the moon orbits the earth.
So, when you finally work out how the moon orbits the earth, you will know how the ISS has stayed in orbit for over 19 years.

But a Haitian Vodou could not be expected to understand all this sciency stuff, so don't let it bother your poor feeble brain.

So the silly fake iss is exactly like the moon now?

How long before you drag this thing in to support your sci-fi fantasies?

The ISS was put together over the years......
Module after module floating in space while the spaceshuttle silently docked and assembled the building blocks together without interrupting it's orbit or velocity...
The powers of imagination have no boundaries in the realms of space......

Pretty cool right?

it is quite awesome to think we managed to do such a thing. It was from being a trivial task.

it is quite awesome to think we managed to do such a thing. It was from being a trivial task.

Who's this 'we', Paul?

And yes, the idea that a space station was somehow built without any blueprints or even records of it being built is far from trivial.

It is impossible.

Or do you have these blueprints and recordings?

Nope, sit down.

The ISS has been accelerated by gravity perpendicular to movement.
(Thing about vectors, not just intensities.)
Tangential speed won't change on its own.
We have to set it to correct value to counter g by centripetal acceleration in the same amount.
Weight F = m v² / r
g = F / m
g = v² / r
(does not depend on mass)
v = SQRT(g * r) = SQRT(8.6822 * 6 771 000) = 7667.28 m/s

Speed of ISS required to counter g by own centripetal acceleration is v = 7.67 km/s.
We will use boost of supply vehicle to adjust tangential speed to that value.

If the vacuum was total, the tangential speed would remain the same all the time.
The two transversal accelerations, centripetal and g, would balance each other and orbit would be stable.
Unfortunately, there are still some remaining molecules that create small drag, and we have to push ISS from time to time back to speed of 7.67 km/s.

EDIT: BTW, difference between balistic and satellite behavior is in further corrections of trajectory.
You are right that by only simple push directly from Earth one can't achieve stable orbit.
What is needed is later correction when the object is already there.

There is no centripetal acceleration on the ISS, as it is not physically tethered to a central axis of rotation or capable of creating friction with its environment:

http://hyperphysics.phy-astr.gsu.edu/hbase/cf.html
.
So your math is worthless.

There is only one force acting on the ISS - gravity.

And gravity will accelerate its velocity by 20mph for every second it is in orbit.

This is the simplest matter possible.

In this case the force is provided by gravity.

We already discussed force fields between molecules, and insignifficance of distances as long as forces are sufficient.
But somehow you decided to ignore that.

Now let's praise the power and conception of the rocket and his founding father :

In all his essence a marvel of modern technology,
Created by an infant of nazism that found a new ideology,

First he destroyed London with some V2 rocket,
But his name was cleansed from the criminal docket

A new episode was dawning for humanity
We left the earth below for a better destiny

Finally a crescent understanding became full
Singing, jumping ,driving ,...no single moment dull

We went back and forth the deep black void
But somehow all we knew was unknowingly destroyed

But we still have the pictures in a gloryfied book
I do hope that no one will notice the way they really look

Obvious, yes. You are blurring things deliberately.

ISS is in gravity force field. Gravity inflicts acceleration towards Earths center.
ISS moves along curve. Center of arc is in the center of the Earth. Movement along that curve inflicts centripetal acceleration opposite to gravity acceleration.
By regulating speed of the ISS we set that centripetal acceleration to be equal g at that altitude and with that radius of local trajectory arc.
When we set proper ISS speed, orbit becomes stable.

Rubbish! There is no "magic" involved.
If the speed or direction is not quite right the satellite goes into a more elliptical orbit than intended and guess what?
That is exactly what happened to the early satellites.

If you want a satellite to have a circular orbit at 400 km altitude the velocity ideally should be 7668.55 m/s.
If due to a burn error it ends up at 7640 m/s the satellite goes into an elliptical orbit of perigee 300 km and apogee 400 km.
But, the satellite doesn't come crashing down. Before the satellite progress far, the speed would be adjusted with a very short burn.

Small minds ridicule what they can't understand. More mature minds use it as the opportunity to learn something new.

You deliberately ignore facts again.
Let me remind you:

"Liquid fuel consists of two tanks, one with liquid hydrogen (or methane or such), another with liquid oxygen.
Solid fuel is mixture of burning material and oxidizer."

Now tell anyone how "nothig burns in vacuum".
And you will be right.
Fuel burns elsewhere: in combustion chamber.

Just about, in a shonky home made vacuum chamber...



Space is a vastly harder vacuum than that.

But try powering a satellite with thermite and see how that works out for you, eh?

And a combustion chamber is not an enclosed space.

It has a big hole in one end and is thus open to the vacuum of space.

Talk about ignoring facts!

<< Irrelevant stuff deleted >>

The fuel in a rocket is not burned in a vacuum, but in the combustion chamber!
The combustion chamber pressure of Saturn F-1 engine was 1,015 psi. Does that seem like a vacuum to you?

Only an ignorant demented Voodoo Priest would be stupid enough to call 1,015 psi a vacuum!

Nah, flat Earther Papa Legba likes the title voodoo priest.
