Today's VIS image shows one of the graben that make up Hyblaeus Fossae. This fracture system is located on the southwest part of the Elysium Volcanic complex and is related to the volcanic and tectonic activity that created Elysium Mons. The whole fossae system is approximately 375km (233 miles) long. Linear depressions of this type are called graben, which form by the down drop of material between two parallel faults.

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.
