This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image, acquired in March 2004, shows gullies formed in the wall of a south middle-latitude crater wall near 39.7°S, 208.6°W. The banked, curved nature of the channels in each gully are among the key indicators that a fluid, such as liquid water, may have been required to form them. The picture covers an area about 3 km (1.9 mi) across 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.
