Caption:

The topic for the Image of the Day for the weeks of March 7-18 will be mountains on Mars.

This is an image of Hydraotes Chaos, the large chaos terrain just east of Valles Marineris. Chaos is typically interpreted to be a collapse terrain; it is the blocky landscape after the transport and removal of subsurface support.

A good diagram showing the structural difference between simple and complex craters is here: http://www.lpi.usra.edu/expmoon/science/craterstructure.html

Image information: VIS instrument. Latitude 1.6, Longitude 325.6 East (34.4 West). 19 meter/pixel resolution.

Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.

Background Info:

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, 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.
