"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.

Subject: [meteorite-list] Meteorites on the moon
Can you imagine hunting meteorites on the moon?
Crustless Diogenites, Eucrites, Howardites strewnabout everywhere.
Pristine Pallasites unaltered by atmospheric pressure or humidity
sticking out of the lunar dust like a gem.
How excited Nasa was when they found one on Mars. I'm surprised there
wasn't a manless mission planned to go to the moon to extract and
return some of these pristine meteorites utilizing a rover. Obviously
it would be tremendously expensive, but, compared to what is spent on
the mars mission as well as expeditions in the arctic its a no -
brainer.
The moon is a meteorite goldmine. 100% impact rates, craters
everywhere pinpointing the spot of impact.
I wonder if Nasa found one gram out of the relatively miniscule amount
of specimens returned from the moon to be of non-lunar origin.
I believe if we want to make monumental advancements in Meteoritics we
need to take advantage of the abundance on the moon. Who knows what
never before seen meteorite types are laying up there right now.
What do you think, Mike? You don't have to worry about any Norwegian
export laws.
