THEMIS ART #83
Tilt your head to the right to "see" the frowning ghost with prominent eyes. This nighttime infrared image shows part of the region of outwash where Mawrth Vallis empties into Chryse Planitia. The dark regions are colder than the bright regions. At night rock retains heat better than dust, so the dark "eyes" are small craters with dust on the floors surrounding a rocky central peak or pit.
Image information: IR instrument. Latitude 26.4N, Longitude 339.4E. 103 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.
