Hi Shawn and Vestoids,

I've been following the Dawn mission (and Ron's regular links) with
great interest. I feel like such a total geek, but this mission has
me excited all across the board - for NASA, for space science, for
planetary science, and for meteoritics.

I think many of us would just love to see close-up photos and data
from the surface of Vesta (and Ceres). Wouldn't it be wonderful to
see big piles of eucrites, howardites, diogenites, and other
meteorites laying around the surface of Vesta?

I think, but I am not sure, that "eucrite-mmict" is a eucrite, monomict breccia.

Meteorite nomenclature is an evolving beast. At one time, CK
meteorites were part of the CV class - CV4, CV5. One thing about
meteorite terminology is for certain - it can change when new data
emerges.

Best regards,

MikeG
