This image shows impact craters of varying size and morphology. The crater with the visible central peak on the southern edge of the image displays spectacular wall slumps, which form when material on the steep walls of the crater collapses. This crater also has secondary craters and ejecta radiating from its center. Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington
