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.

Indeed, Vesta's midsection does look as if it has been worked on a lathe. But the rotational axis on an actual lathe is maintained by a mechanically rigid piece of machinery. For a pair of free-spinning celestial bodies, it is hard to see how they could maintain just the right distance for several revolutions so to gouge out the grooves without bouncing off, melting, breaking up, merging, etc. The sort of light, plowing, contact that monty is considering is a pretty unstable situation. That said, I don't have a better idea to explain how the grooves got there. I assume some common cause must operate on vesta, phobos, lutezia, maybe even iapetus, but most of the contending stories have holes in them. Let's keep working on it.
