Context image

This VIS image shows an unnamed crater in Acidalia Planitia. The margins of the ejecta are lobate and higher than the ejecta closer to the crater. This type of ejecta blanket is called rampart and it is thought that a volitile material like water may have played a role in creating this morphology. The crater is fairly pristine, and therefore relatively young.

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.
