Feast your eyes on an intriguing crater with bright material on its walls. This image, taken by NASA's Dawn spacecraft, shows a portion of the southern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image, with a resolution of 450 feet (140 meters) per pixel, was taken on August 21, 2015.
Dawn began spiraling down to its third Ceres science orbit on June 30 but experienced a problem almost immediately and went into a protective "safe mode." The mission team has now determined what happened and cleared Dawn to return to work.
