English: PIA20000: Dawn HAMO Image 57

http://photojournal.jpl.nasa.gov/catalog/PIA20000

This image of Ceres, taken by NASA's Dawn spacecraft, demonstrates how the relative ages of impact craters can be revealed by their positions relative to each other. In many cases, as with the craters at the center of this view, younger craters are seen to be "superposed" on -- meaning located on top of -- older craters below.

The largest feature in the image scene is the 48-mile-wide (77-kilometer-wide) Geshtin crater, which is superposed by the younger Datan crater, which is 37 miles (60 kilometers) in diameter. On its upper-left rim, Datan is superposed by a smaller, even younger unnamed crater.

The image was taken on Oct. 2, 2015, from an altitude of 915 miles (1,470 kilometers), and has a resolution of 450 feet (140 meters) per pixel. The image is centered at approximately 59 degrees north latitude, 258 degrees east longitude.

Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK, Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.
