NASA's Mars Global Surveyor shows a portion of Corasis Fossae valleys. These subdued valleys and pits show structural control. The pattern of pitting suggests removal of subsurface support may have played an important role in valley formation.

Portion of Corasis Fossae valleys (MOC 8205). These subdued valleys (35.6°S, 75.4°W) show structural control, as do pits in the center of the upper half of image. The pattern of pitting suggests removal of subsurface support may have played an important role in valley formation. The adjacent upland surface is not dissected. This slightly oblique view (emission angle = 20.7°) was taken at low incidence angle (25.4°); the downtrack scale is 11.5 m/pixel and the crosstrack scale is 6.6 m/pixel.

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, CA. 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, CA and Denver, CO.
