Context image

Today's VIS image contains a section of one of the many channel forms found on the northwestern side of the Elysium Mons volcanic complex. The channel features are thought to have both a tectonic and volcanic origin. The linear depression resembles a graben (formed by tectonic forces) and the smaller sinuous channels to the top of the image more closely resemble features caused by fluid flow - either lava or water created by melting subsurface ice by volcanic heating.

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.
