The top half of this THEMIS visible image shows interior layered deposits that have long been recognized in Valles Marineris. Upon close examination, the layers appear to be eroding differently, indicating different levels of competency. This, in turn, may be interpreted to indicate different materials, and/or depositional processes. At the bottom of the image, materials eroded from the walls of the canyon form dunes and other aeolian bedforms.
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.
Image information: VIS instrument. Latitude -6.5°, Longitude 287.3° East (72.7%deg; West). 19 meter/pixel resolution.
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.
