NASA's Mars Odyssey spacecraft captured this image in July 2003, showing the western slope of the Tharsis volcanic bulge. This landscape on Mars shows the effect of the large-scale wind regime of the region.


Released 24 July 2003

Located on the western slope of the Tharsis volcanic bulge, this landscape shows the effect of the large-scale wind regime of the region. The northwest/southeast trending yardangs may have been eroded by winds from both directions, but there are some indicators, primarily on the lower left mesa, that the streamlined forms resulted from downslope (to the northwest) winds.

Image information: VIS instrument. Latitude -5, Longitude 200.3 East (159.7 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.
