This VIS image shows part of the inner rim of an unnamed crater in Terra Sabaea. Numerous dark streaks mark the slopes of the inner rim. There are several suggested mechanisms to form these features. Two of the mechanisms are that the dusty surface has been altered to reveal darker rock beneath from motion of downward moving dust, or the surface is darkening by fluid or other surface staining.

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.
