Oblique view of Gale Crater Mound

MGS MOC Release No. MOC2-265E, 4 December 2000


A mound more than 2.3 kilometers (1.4 miles) thick found in the middle of Gale Crater at 5.4°S 222.2°W exhibits a complex history of sediment deposition, followed by lithification---i.e. hardening to form rock---followed by erosion, cratering, and then more deposition and lithification. This oblique view of Gale Crater, looking toward the southeast, was generated using Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle images and MGS laser altimetry. The colored box represents a geologic map of the different layers in the mound that were observed in MOC narrow angle image M03-01521 taken in July 1999. The colored map appears in the three pictures that follow this one, "Layered Unit in Gale Crater Mound," "Unconformity in Gale Crater Mound," and "Massive Unit in Gale Crater Mound," to illustrate different aspects of the complicated geology revealed by MOC in this area. For additional information about this picture, see Sediment History Preserved in Gale Crater Central Mound, MOC2-260, December 4, 2000.

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.
