[meteorite-list] Meteorites on the moon

[Chris Peterson]

"Unaltered by atmospheric pressure" also implies unslowed by any 
atmosphere. So everything that hits the Moon is doing so at a minimum of 
around 2.5 km/s, and usually a lot more. I don't think you'll find many 
meteorites.

As thin as the Martian atmosphere is, it is enough to provide 
aerobraking. The rover cameras have apparently recorded a few meteors.
