The Earth's atmosphere does NOT end at 100 km: http://en.wikipedia.org/wiki/Earth%27s_atmosphere
The 100 km figure was just someone at NASA making an executive decision because someone insisted on a number.

I don't have an exact numbner of miles up from earth, but I have an interesting factoid to make a comparison between the size of Earth and the depth of its atmosphere.
If the Earth were an apple, the atmosphere would be thinner than the apple's skin

Hi. Most agree that 100 km is the end of the atmosphere. Look up ' SpaceShipOne '
