PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Large impacts produce uplifted central structures, either peaks, or pits, or an uplifted peak with a central pit. This crater south of Aurorae Chaos has a central pit exposing bedrock units with diverse colors, indicating diverse rock compositions.

This crater includes clay-rich minerals identified by the CRISM instrument on MRO. See this enhanced-color cutout over the eastern half of the central pit.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 53.4 centimeters [21.0 inches] per pixel [with 2 x 2 binning]; objects on the order of 160 centimeters [63.0 inches] across are resolved.) North is up.

This is a stereo pair with ESP_044930_1690.

The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.
