Hi,
Presumably then a similar story is true
for Martian meteorites? Any trace of chondritic material in Martians?

Mark, List,
There was an article in either Astronomy or Sky and
Telescope just a few years ago about how Mars would
actually be a GREAT place to find meteorites. I have
to leave now and can't search for it, but I'm sure
some of the members will remember it. The article
essentially stated that

Couple of points
One small meteorite was recovered in the Apollo
Program (Hadley Rill?).(Details anyone?) Didn't it
possess impact pockmarks?
Yes. There's one of the Apollo photos clearly shows an
ipact mark. A tiny crater in a large rock. I believe
this shows that there's not likely to be much

...lunar impacts are rarer than Earth ones due to the
weak gravity of the moon and not just it's smaller
cross-section.

Can you imagine hunting meteorites on the moon?

According to my Meteorites from A to Z (2nd ed.):
Bench Crater; CM1
Hadley Rille; EH
Already we're finding more than the usual L6 and H5s. However, being
exotics,
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
At what velocity do you think Canyon Diablo impacted?
I think we found some pieces of that asteroid.

without an atmosphere to slow them, the bulk of
meteoroids arrive at full cosmic speeds and are most
certainly vaporized by the collision. I haven't done
the math but under an extreme
