Full data on this image has now been released via the THEMIS Data Releases website.



The Odyssey spacecraft has completed a full Mars year of observations

of the red planet. For the next several weeks the Image of the Day

will look back over this first mars year. It will focus on five

and expansion of the caps; 2) craters – with a variety of morphologies

relating to impact materials and later alteration, both infilling

and exhumation; 3) channels – the clues to liquid surface flow;

4) volcanic flow features; and 5) dunes. While some images have helped answer

questions about the history of Mars, many have raised new questions

that are still being investigated as Odyssey continues collecting

data as it orbits Mars.

The channel shown on the image is part of the Tinia Vallis region. It was collected July 11, 2002 during southern autumn season. The local time is 4pm. The image shows a small channel with a delta.

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.
