This VIS image shows a large linear depression in the center of an unnamed crater in Noachis Terra. This crater and the nearby Maunder and Asimov craters share this odd morphology. The crater floors have been filled to the rim and then depressions have occurred in that fill material. In the case of Maunder and Asimov, the depressions occur along the inner rim of each crater. In this crater, the depression is located in the middle of the crater fill.

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.
