Vestan Dawn: the rising sun casts long shadows across the giant asteroid Vesta, as seen from very low orbit by NASA’s ion-engined Dawn spacecraft, now only 124 miles above the surface. Rockslides are visible on the sunlit side of the impact crater to the right, and chains of pits across Vesta’s surface mid-image show the aftermath of another impact that threw material across the asteroid’s face (image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA).
