If you've ever wanted see what it would look like to orbit the asteroid Vesta in 3D, now's your chance. You have to have red/green glasses, but I bet after seeing all the anaglyph posts I've made, a lot of you do. Anyway, this animation was made by NASA/JPL using data from the space probe Dawn when it was orbiting Vesta at a height of about 2700 km (1700 miles):

Very cool. I was struck the most by how the gigantic mound in the center of the south pole basin has actual and substantially-sized craters in it from impacts! Airless bodies have craters all over them -- unless they resurface themselves, like Io's volcanoes do or they have undersurface oceans like Enceladus and Europa -- so it's natural to see craters on a mountain. But usually mountains are relatively small, so big craters would wipe them out. But that mound on Vesta is huge -- it rises 23 km (14 miles) above the basin floor! So there's easily room on it for big craters.

Vesta's a weird place, and I'm glad we're studying it so closely. Even more closely than before in fact, since a couple of months ago Dawn dropped to only 750 km from the surface. The images it's returning now are really amazing... as you can see for yourself!
