In April, 2012, the Dawn spacecraft was a mere 272 kilometers (170 miles) from the surface of the asteroid Vesta when it took this wonderful picture of the crater Licinia:
[And oh yes, you want to click to envirgingoddessenate - it links to a picture of the area around the crater as well.] Licinia is about 25 km (15 miles) across - too big to fit in Dawn's field-of-view from that height. But it does show spectacular detail, including what look like landslides into the bowl from the crater rim; you can see them as dark streaks running down the crater wall. Mounds of material at the base of the crater wall indicate bigger landslides, too.

While I was inspecting the crater floor, I ...
