This image from NASA's Mars Odyssey spacecraft shows a portion of the floor of Ophir Chasma on Mars. At top is a landslide deposit. In the center is a wind and perhaps water eroded highland. At bottom wind appears to be the main agent of erosion.

This VIS image shows a portion of the floor of Ophir Chasma. At the top of the frame is a landslide deposit. In the center is a wind and perhaps water eroded highland. At the bottom part of the image wind appears to be the main agent of erosion.

Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, 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.
