The linear depressions in this image from NASA's 2001 Mars Odyssey spacecraft are graben. Graben are formed from tectonic activity with large blocks of material moving downward between paired faults.
Context Image

The linear depressions in this VIS image are graben. Graben are formed from tectonic activity with large blocks of material moving downward between paired faults. The crater in the bottom half of the image is oval rather than round, which could have been due to impacting into this region of tectonic deformation.

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.
