According to Dawn (who ought to know) the descent to the next mapping orbit is beginning now.
"NASA_Dawn NASA's Dawn Mission I'm done with Survey science operations today!! Time for a several-week transfer down to High Altitude Mapping Orbit (HAMO)!! 20 hours ago" Better pics on the way! Thanks, Dawn team, for the pictures so far. Will we learn of any preliminary nomenclature soon? Phil -------------------- ... because the Solar System ain't gonna map itself.

It's strange isn't it. I see areas on vesta that look like hummocky flow features -like land slide debris - covering the surface. But the half craters look younger than this debris. Could it be that this debris is varying in thickness and distribution so that the the cratering events here punched into only parts of this less consolidated stuff which partially slumped into these craters?

The differing depth of loose ejecta may come into it, the boundary of the slump in the lower crater certainly climbs the slope of the smooth wall to the south. But I think that the angle of incidence of the impact may also have an effect. The floor of the crater is not in the center.
