This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows
the remains of two impact craters that were filled, buried, and then
exhumed from within layered sedimentary rock in the martian crater,
Gale. Wind erosion has sculpted tapered yardang ridges in the uppermost
rock layers exposed at this location.|
This is the 1000th captioned image release from the MGS MOC team. The first release occurred in July 1997, when the spacecraft was still speeding toward the red planet. Many people have asked "why are the releases numbered starting with 'MOC2'?" The MGS MOC is the second MOC, so it is designated "MOC2". The first MOC was flown on the Mars Observer spacecraft, which was lost just before arrival at Mars in August 1993. The MOC science investigation was originally selected by NASA in 1986. The MGS MOC effort is currently in its third extended mission, and is funded through at least October 2006.

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.
