This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows low, broad sand dunes and sheets in southern Briault Crater near 10.1°S, 270.7°W. In this case, winds have swept up all available sand in Briault Crater, and moved it toward the south side of the basin. The wind streak pattern of these landforms indicates that the dominant winds blow from the north (top) toward the south. The image covers an area about 3 km (1.9 mi) wide and is illuminated by sunlight from the upper 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.
