Terraced Wall Crater

Today's image shows an unnamed crater located in Arabia Terra. The small crater seen in the image is located on the floor of a much larger crater. The details visible in the crater indicate that it is a relatively youthful crater exhibiting pre-erosion morphology. This crater shape is a central peak with two rims that are close together. The inner ring is actually part of the original rim that slumped downward during the impact event. The inner rim is mostly a flat terrace, giving this a crater morphology type the name terraced wall crater. Small dark dunes are visible in the lower left corner of the image.

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.
