Mars Odyssey THEMIS Image: Destination: Gusev
 Image Context:  Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] Yesterday, a Delta II rocket successfully lifted off from Cape Canaveral, Florida carrying the Mars Exploration Rover named Spirit. Its destination is a crater called Gusev in the southern hemisphere of Mars. This crater may have been the site of an ancient lake whose sediments could be sampled by Spirit. The THEMIS image covers a portion of the center of the elliptical region in which the rover is expected to land nearly seven months from now. The scene contains wispy dark streaks that probably arise from the removal by wind of a layer of bright dust. Just to the south of the dark streaks is a boundary that may represent the edge of a layer of material that has flowed in from the south. With luck, Spirit will have access to a variety of interesting rock types and terrains that will settle the question of whether Gusev crater hosted a lake.

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.
