Fresh crater with dark and bright material

PASADENA, Calif. -- This detail of a Dawn FC (framing camera) image shows a fresh scarp rimmed crater with a remarkable distribution of bright and dark material in its interior. Most of this bright and dark material originates from the crater rim but some originates much farther down the inwardly dipping crater walls. Especially curious is the left hand side of the crater where a layer of dark material crops out about half way down the crater wall, below the bright material which crops out from the crater rim. The high resolution of this image also allows the pitted floor of this crater to become visible. Radial streaks of ejecta surround the crater and are superimposed on the older, densely cratered landscape. This landscape is identified as being older than the scarp rimmed crater because the craters it contains are older with less fresh, more eroded rims.
NASA’s Dawn spacecraft obtained this image with its framing camera on October 2nd 2011. These images were taken through the camera’s clear filter. The distance to the surface is 670km and the image resolution is about 63 meters per pixel.
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.
