This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows some of the troughs of the Granicus Valles system, located west of the Elysium volcanic rise near 27.1°N, 224.0°W. The floors exhibit abundant large ripple-like features deposited and shaped by wind. The dark dots on the valley floors are large boulders. The image covers an area approximately 3 km (1.9 mi) wide; sunlight illuminates the scene from the 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.
