English: PIA19547: Ceres RC3 Animation
http://photojournal.jpl.nasa.gov/catalog/PIA19547 http://www.jpl.nasa.gov/news/news.php?feature=4582 Selected frames cropped around crater with white spots. Contrast increased by gamma correction. Each frame is shown for 0.2 seconds, first and last frame 1.0 seconds, and repeated backwards. In this closest-yet view of Ceres, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. This is from an animation of sequences taken by NASA's Dawn spacecraft on May 4, 2015. This animation shows a sequence of images taken by NASA's Dawn spacecraft on May 4, 2015, from a distance of 8,400 miles (13,600 kilometers), in its RC3 mapping orbit. The image resolution is 0.8 mile (1.3 kilometers) per pixel. In this closest-yet view, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. However, their exact nature remains unknown. 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.
