ISS Again...

NASA asserts two things about the ISS:
1) It is within our atmosphere
2) Our atmosphere, at that altitude, is 4000 degrees

Source please?

I say again, the atmospheric drag at 350 kilometers is small enough to be negligible, and the external temperature of the station is on the order of a few hundred degrees, not a few thousand.

NASA asserts two things about the ISS:
1) It is within our atmosphere
2) Our atmosphere, at that altitude, is 4000 degrees

I'm not going to dispute those points. But I will ask again: Why is that a concern?

Are you extrapolating your experience at 90^o at standard pressure to 4000^o at negligible pressure? The energy contained in the first situation is many orders of magnitude greater than the second. The heating effect is likewise greatly diminished.

Why can't any RE'er explain how an orbiting space station can speed through our atmosphere without slowing down?

The main reason would be that an orbiting space station slows down while speeding through our atmosphere. Why would you think otherwise?

Well you re'ers keep pretending the ISS can stay afloat with a constant headwind.

The ISS would not stay afloat with the assistance of boosts from the rockets of visiting crafts. The very rarefied atmosphere's drag on the ISS is very slight but accumulates over months. The drag reduces the speed of the ISS and its orbit lowers. The boost from the visiting crafts raised the ISS back to a higher orbit and the process starts over.

I accept. But still, how are they not cooking at 4000 degrees?

Oi narc. just give us a fucking source you fucking retard!!!!!!!!!!!!!!!!!!!!

Or stop tugging on the apron and catch up to the conversation that left you.

Give us a source and I am sure that he will.

@Max, vdp and others unable to acquire information without it being spoonfed them.

1) What altitude is the ISS orbiting earth at?
2) What layer of the atmosphere is contained at that altitude?
3) What temperature is the atmosphere at that altitude?

You are free to use the information I gave you or you can use your own. Either way, we've moved on.

Either the way the ball is in your court.
A. Provide the source
B. Explain the reason that you extrapolated for one condition to another without considering the physics involved.

Lol, anything for an argument. Right gully?

Shut the hell up all of you!


RE'ers, stop feeding the troll, and actually look it up. The atmosphere at those altitudes is actually at close to that temperature. HOWEVER, the air pressure is so low at that altitude that this temperature is negligible.

Wow, what i said a page or two ago. But i got yelled at for not "understanding what was going on. I explained it really simple for the troll so people look at me like i'm simple.

Assfucks.

Agreed.

Once again:

1) The ISS is orbiting the Earth at an altitude of about 350 kilometers (as I have said in my previous posts.)

2) There is no significant atmospheric presence at that altitude.  It is, for all intents and purposes, a vacuum.  (As I have said in my previous posts.)

3) As a vacuum, it makes no sense to talk about its temperature.  The exterior of the station itself is heated to a few hundred degrees Fahrenheit, but this is due to direct heating from the sun, not atmospheric heating (as there is no significant atmosphere at that altitude.)



Okay, now I am going to make this as simple as I can.

You have claimed that NASA made the following statement

NASA asserts two things about the ISS:
1) It is within our atmosphere
2) Our atmosphere, at that altitude, is 4000 degrees

And now I ask you, plain and simple.





What is your source for this statement?

Where are you getting your information on the ISS?  Could you please provide a source?  Because your claim about it's orbital altitude is seriously in error.

http://spaceflight.nasa.gov/realdata/tracking/index.html

350 kilometers.  Well outside the bulk of Earth's atmosphere.

And where did you get 4000 degrees Fahrenheit?  While I'll admit that I can't find an official NASA source on the topic, I have learned from popular sources that the exterior temperature of the ISS is only a few hundred degrees F in direct sunlight.  And as you can see from the above link, the interior temperature is kept comfortably below that!

That temperature makes sense if you think about it.  In RE, the sun's surface temperature is about 6000 degrees C, and we are 150,000,000 kilometers away.  I'll run through the math if you want, but an object the size of the station simply can't intercept enough energy from the sun to raise it's temperature to several thousand degrees.

I think that nadbungles was referring to re-entry of a body through the ISS. He left that out intentionally, because even on his best days, Narcberry is a troll like no other.

Well Narcberry, your ability to post incomplete details about some things truly amazes me.
What's more amazing is that you then proceed to debate a subject and ask for evidence to the contrary.
Truly magnificent.
If you do have a coulpe of minutes, I would suggest that you take a look at this page.

If you will look at the very last paragraph you will find this:

The last atmospheric layer has an altitude greater than 80 kilometers and is called the thermosphere. Temperatures in this layer can be as high as 1200° C. These high temperatures are generated from the absorption of intense solar radiation by oxygen molecules (O2). While these temperatures seem extreme, the amount of heat energy involved is very small. The amount of heat stored in a substance is controlled in part by its mass. The air in the thermosphere is extremely thin with individual gas molecules being separated from each other by large distances. Consequently, measuring the temperature of thermosphere with a thermometer is a very difficult process.  Thermometers measure the temperature of bodies via the movement of heat energy.  Normally, this process takes a few minutes for the conductive transfer of kinetic energy from countless molecules in the body of a substance to the expanding liquid inside the thermometer.  In the thermosphere, our thermometer would lose more heat energy from radiative emission then what it would gain from making occasional contact with extremely hot gas molecules.

That Layered Atmosphere fellow is quite the sharp old bean.

"The thermosphere, named from the Greek θερμός (thermos) for heat, begins about 80 km above the earth. At these high altitudes, the residual atmospheric gases sort into strata according to molecular mass (see turbosphere). Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation by the small amount of residual oxygen still present. Temperatures are highly dependent on solar activity, and can rise to 2,000°C. Radiation causes the air particles in this layer to become electrically charged (see ionosphere), enabling radio waves to bounce off and be received beyond the horizon. At the exosphere, beginning at 500 to 1,000km above the earth's surface, the atmosphere blends into space.

The few particles of gas in this area can reach 2,500°C (4500°F) during the day. Even though the temperature is so high, one would not feel warm in the thermosphere, because it is so near vacuum that there is not enough contact with the few atoms of gas to transfer much heat. A normal thermometer would read significantly below 0°C."

It was a good attempt while it lasted narc.

This just in!!!

Space Stations can fly through atmosphere without drag, astronauts safe at 4000 degrees!
As it turns out, headwind is a negligeable force. This recent discovery gives much opportunity for aeronautical engineers, as they can now leave out this once-critical aspect of design.

Also temperature is a quanitity!! New designs for the home oven will now have a dial ranging from 200 degrees to lots and lots of 200 degrees. These new low temperature ovens will cook in half the time!!




You RE'ers will say anything to keep the iss floating in the atmosphere.

This just in. No, not really. We've know that dingleberry can't reason.

dingleberry has extrapolated his experience at standard pressures to the negligible pressures of the outer atmosphere. His reasoning being that only what he's experienced must apply everywhere.

Which are you arguing now? That it isn't hot up there or that there isn't enough 4000 degrees?

Which are you arguing now? That it isn't hot up there or that there isn't enough 4000 degrees?

Which are you arguing now:
1) Because you feel warmer at 90^o SP than at 70^o SP, you would feel even warmer at 4000^o at negligible pressure?

-or-
 
2) Your mother dropped you on your head many times before she left you at the orphanage?

-or-

both?

No you!

LOL
