This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows details near the front edge of a lava flow in the Daedalia Planum region. Daedalia Planum is a vast region covered with the extremely large lava flows of southern Tharsis. The trough in the lower third of the image is a graben formed by extension and faulting of the martian crust. This image is located near 28.1°S, 135.0°W, and covers an area approximately 3 km (1.9 mi) across. Sunlight illuminates the scene 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.
