Moon Rock Suggests the Young Moon Had a Fiery Core and

Regarding meteorites on the Moon...
There is a great deal of meteoritic matter on the Moon, but very
few meteorites. The two miniscule fragments that Martin Altmann mentioned
are the best known ones from the Apollo collection, but I'm aware of 2
others
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

I'm aware of 2 others even smaller.
Virtually all meteoroids 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

Fascinating piece of info Martin

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,
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

Actually, physics-ly speaking, Earth holds far more
meteorites than the moon does. Be it remembered, that
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

Hello Tracy and List,
a) Bench Crater - shocked CM1 (contains water-bearing minerals)
b) Hadley Rille - EH
Two meteorites found on the Moon have been named: Bench Crater and
Hadley Rille. There are an additional two probable iron meteorite
fragments, a 2-mm fragment recovered from the fines fraction of
Apollo 11 regiolith sample 10085-18, and a 0.3x0.4-mm iron
fragment from Apollo 16 regolith core
Hi, List,
Will any meteorite survive impact on the Moon?
In general, a meteorite will remain intact on impact (or only
crack into large fragments) if it hits a hard surface at a speed
slower than the velocity of sound inside the body of the
meteorite.
Huh? Well, the shock wave of
