This image of Ceres, taken by NASA's Dawn spacecraft, shows three prominent craters located to the northeast of a terrace (the terrace feature being located at left in this image). The lower two craters, which are larger, have polygonal rims. The steep crater walls, distinct rim and visible ejecta of the upper smaller crater, called Oxo, hint at a fresh impact. Oxo is about 6 miles (9 kilometers) in diameter. Another interesting feature in this view is a short, linear slump, where a mass of material has dropped below the surface, to the east (or right in this view) of Oxo.
The image was taken on Oct. 8, 2015, from an altitude of 915 miles (1,470 kilometers), and has a resolution of 450 feet (140 meters) per pixel. The image is located at 42 degrees north latitude, 358 degrees east longitude.
The Dawn mission to Vesta and Ceres is managed by NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA’s Science Mission Directorate, Washington D.C. UCLA is responsible for overall Dawn mission science.
The Dawn framing cameras have been developed and built under the leadership of the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany, with significant contributions by DLR German Aerospace Center, Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The framing camera project is funded by the Max Planck Society, DLR, and NASA/JPL.
