Context image

While the crater in this VIS image was crated by an impact event, the resultant form is not the normal circular shape. There are several factors that can create 'out of round' craters. The most common is subsurface faulting from tectonic activity. Pre-existing subsurface fractures can deflect impact pressures along the fault faces, rather than uniformly radially from the center of impact. Meteor Crater in Arizona has "corners" due to the same tectonic forcing of impact pressures.

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.
