This mosaic image of Valles Marineris - colored to resemble the martian surface - comes from the Thermal Emission Imaging System, a visible-light and infrared-sensing camera on NASA's Mars Odyssey orbiter.Built from more than 500 daytime infrared photos, the mosaic shows the whole valley. Despite the valley's huge extent - including its western extension through Noctis Labyrinthus, it reaches some 3,000 kilometers (2,000 miles) long - the smallest details visible in the image are about the size of a football field: 100 meters (328 feet).
