This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows landforms in southeastern Ius Chasma, part of the Valles Marineris trough system. Near the top of the image are light-toned rock outcrops; at the bottom center is a small butte--the remnant of some formerly more extensive rock unit. The lower two thirds of the picture is dominated by dark, windblown sand dunes. The image is located near 8.7°S, 79.2°W, and covers an area about 3 km (1.9 mi) across. Sunlight illuminates the terrain from the lower left.
Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, California. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, California and Denver, Colorado.
