Just 'cause I said I would...
Hopefully, though, this whole episode has made its point -- NASA isn't afraid to tell overbudget missions to stand down. I just *really* wish we could get the magnetometer back on the beastie, though... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

As a matter of fact, the fact that a lot of the asteroids may still have been partially melted when they ran into (or near) each other has immediate relevance to the most startling of the theories: Erik Asphaug's belief that a lot of the asteroids were broken apart, not by direct impacts, but by tidal forces when they happened to fly near the larger protoplanetary embryos that still existed in the Belt during its earliest days. (Apparently, for instance, a single such encounter would do a much neater job of pulling all the silicate mantle off an asteroid's already-solidified iron core than even a series of repeated impacts would do.) As I say, more on all this later.
