Craters on Vesta
Different personalities of craters on Vesta, as seen in the images taken during a rotation characterization on July 24, 2011. All are at about the same scale, with each square very roughly 75 kilometers across. Clockwise from top left: one of the splashy fresh craters with its strange cascades of dark material; a larger, crisp-looking crater, one of the Snowman triplet; what I think is a crater similar in size to the Snowman one, but heavily degraded and covered with other, smaller impact craters; and some southern hemisphere terrain, featuring a couple of small fresh craters but also some crater-free intercrater plains, suggesting this area is more youthful than the northern hemisphere.
