Thermosphere is a part of the atmosphere and starts with aititude 100 kms and finishes about 700 kms.
Thermosphere has a temperature between the low one is 200 Celsius degrees that about double of the boiling temperature of water; and the highest one goes to 1600 Celsius degrees that about %80 of oxygen gas welder.
Thermosphere in this state is like as a small hell.
So entering thermosphere is same with entering hell for all human, animal, live or inanimate.
If NASA had really passed that "HELL", then must show on the earth how an rocket passing from an area has 200 to 1600 celcius temperature about a time while same vehicle has human on it and don't dead.
Is somebody see a test like this? i don't think so. Who want to enter to the hell? But it is easy to pass a hell on a computer animation
Just how long do have to put up with these ignorant statements that keep being made about the thermosphere?
It is true that the
temperature of the gases in the thermosphere is extremely high,
but to transfer heat to an object (spacecraft or satellite) the amount of thermal energy is also extremely important.
The nominal start of space (and the
thermosphere) is the Kármán line at 100 km altitude.
At this the air density is about
1/2200000 the density on the surface, and decreases roughly exponentially above that.
The table on the right shows the number of molecules (air or otherwise) at various altitudes relative to the number at sea level (altitude = 0 km).
As you can there is essentially nothing at those altitudes to contain any heat - the "heat capacity" is close enough to ZERO.
| | Altitude | | Relative Density | | Or if you like a lot of 0's | 0 km | | 1.0000 | | 1 | 40 km | | 0.0033 | | 1/307 | 100 km | | 4.67E-07 | | 1/2,140,000 | 200 km | | 2.82-10 | | 1/3,550,000,000 | 400 km | | 4.15E-12 | | 1/241,000,000,000 | 1,000 km | | 2.14E-14 | | 1/46,800,000,000,000 |

This makes to gas in the thermosphere an almost perfect insulator.
We can make insulating tiles that have such a low heat capacity and low thermal conductivity that a white hot tile can be held safely in the hand!
Take a look at this picture an video.These tiles have a density of
140 kg/m3. That looks a lot, but remember that water has a density of
1,000 kg/m3.
Air at sea level has a
density of 1.225 kg/m3 and the "atmosphere" at even 100 km has a density of roughly (it varies a lot) is only
5.7 x 10-7 kg/m3 (or
1/1,750,000 kg/m3 if you prefer).
So just imagine how much less the
heat capacity and
thermal conductivity of the thermosphere is than these tiles!
Now please put this question to bed! The thermosphere does not burn anything up because there if virtually nothing there!
And while we are at it the atmosphere does not FLY AWAY because at these extreme altitudes there is no atmosphere "to fly away", it is all held lower by gravity.It's just more of "I don't understand the globe, so the earth must be flat".
I know İntikam will not read this. Well, I could not care less, he is simple so ignorant that he will never learn, but just possibly others might look further into it!
