Long before the MER landers were named or launched, the two orbiters at Mars were asked to examine landing sites. Both the Odyssey and Mars Global Surveyor spacecraft have been collecting landing site data for the past two years. The MGS and ODY data were used as part of the decision making process in the final selection of the two landing sites. The types of data collected by the two orbiters included not only images of the surface but also thermal data about the surface composition, atmospheric data about the climate at each location, and the tracking of major dust storms in the region prior to landing. The presence of, and data collected by, the MGS and ODY orbiters have proven invaluable in MER mission planning.

This infrared image covers most of the eastern side of Gusev crater, slightly to the east of Spirit’s landing spot. To the south, it shows the northern end of Ma’adim Vallis, which is thought to have brought water into Gusev crater in the distant past. This image was taken on 2 August 2002.

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.
