I read an article in a science mag. awhile back entitled "The ten misconceptions NASA tour guides hear". They said that air friction is not responsible for the heating of fast moving objects through the atmosphere, but highly compressed air at the leading edges. Now that I am enlightened, could anyone tell me the PSI that the shuttle sees on its nose area? Also the temp? This may be a tough one, but how about the PSI and temp of a meteor entering our atmosphere? Thanks Guys!
