Caption:
The pattern of ejecta from a young crater is still preserved on the floor of Van de Graaff crater. The variations in albedo (bright and dark areas in the ejecta) indicate either different surface exposure times, grain sizes, or composition. Image is from NAC frame M110479695L with a width of 650 meters (2132 feet) and an incidence angle of 30°.
Background Info:
NASA's Goddard Space Flight Center built and manages the mission for the Exploration Systems Mission Directorate at NASA Headquarters in Washington. The Lunar Reconnaissance Orbiter Camera was designed to acquire data for landing site certification and to conduct polar illumination studies and global mapping. Operated by Arizona State University, LROC consists of a pair of narrow-angle cameras (NAC) and a single wide-angle camera (WAC). The mission is expected to return over 70 terabytes of image data.
