. . . groan! . . . -100ºF is only a small part of it huh?


The atmospheric profile shows some interesting things. In the
Troposphere, the temperature drops pretty steadily until around 10 Km,
then it tends to stay pretty consistent until 20 Km. Above 20 Km, the
temperature actually rises somewhat until around 50 Km, at which point
it drops again until around 85 Km. At this point it becomes the
Thermosphere, in which the temperatures rise dramatically - they can get
from 500 to 1500 degrees C.



Yo for chrissake Mike, I just noticed this gem, 1500ºC is 2732ºF, over
a thousand degrees hotter than the melting point of steel!

. . WTF . . ?!


The atmosphere does indeed heat up in the area known as the Thermosphere

If you don't believe me, here is some info from NASA. They give even
higher values as a maximum.


http://liftoff.msfc.nasa.gov/academy...tmosphere.html

and

http://en.wikipedia.org/wiki/Thermosphere

gives a nice explanation of the Thermosphere, and there is a bit of info
there as to why Amateurs should be interested in it.


A good question is "Why doesn't everything that passes through the
thermosphere burn up?" Because they don't. In fact, despite these high
temps, things passing through this region would "feel" cold.

Why should Hams know about the Thermosphere?



I don't know how to water this down so I'll be blunt about it. You
really do need to consider biting the bullet and delegating the
technical aspects of this project to some technoid(s) and stick to
being the head cheerleader. Preferably before somebody gets hurt .



Thanks for the bluntness Brian. I always appreciate it.

I will be likewise blunt. You are completely wrong about the people
doing (or not doing) this. You *don't* understand some *very* basic
things about the atmosphere, things that you should know as a Ham. Given
those facts, I'll take your judgment of my qualifications to do this
thing under advisement.

Be ****ed or hate me, it's how it is.
