Changing Winds

This infrared image shows part of Zephyria Planum. This region is well named, Zephyria is one of the winged mares of Selene (the moon goddess of Greek mythology), and this region has been subject to intense wind activity. Each level of surface in this image records a different wind direction. Note the small double-circle opening in the thumbnail which reveals a surface etched in a NW/SE direction beneath one etched by the wind in a NNW/SSE direction.

Image information: IR instrument. Latitude -0.1N, Longitude 151.6°E. 98 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.
