Wind erosion has created yardang ridges and revealed the location of a formerly-buried meteor crater (see lower left corner) in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image. This scene is located in the Apollinaris Sulci region near 11.4°S, 181.6°W, and covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the landforms from the left/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.
