The Hephaestus Fossae are a series of collapsed pits and troughs in central Elysium Planitia. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) provides a high resolution view of the floors, walls, and terrain surrounding a few of the pits and troughs in this region. The image is located near 23.0°N, 239.4°W and is about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower 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.
