NASA's Mars Odyssey spacecraft captured this image in July 2003, showing the strange landscape of the eroding Medusa Fossae Formation. In the southern portion, small mounds of sedimentary material are all that remains of a once more continuous layer.


Through the haze of a dissipating dust storm in the southern hemisphere, the strange landscape of the eroding Medusa Fossae Formation is still evident. In the southern portion of this image, small mounds of sedimentary material are all that remains of a once more continuous layer. This former layer was deposited on a pre-existing landscape that was itself already heavily eroded and disrupted.

Image information: VIS instrument. Latitude -4, Longitude 155 East (205 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.

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.
