Welcome to the Mars Orbiter Camera (MOC) Image Gallery! This site contains the pictures of Mars acquired by NASA's Mars Global Surveyor (MGS) orbiter through August 2000.
MOC is operated daily at Malin Space Science Systems (MSSS). MOC consists of three cameras: A narrow angle system that provides grayscale high resolution views of the planet's surface (1.5 to 12 m/pixel in the Mapping Phase of the mission), and red and blue wide angle cameras that provide daily global weather monitoring, context images to determine where the narrow angle views were actually acquired, and regional coverage to monitor variable surface features such as polar frost and wind streaks. Most of the high resolution images are obtained by careful planning and inspection of predicted MGS orbits by Mars scientists working at and/or visiting MSSS. The company is also responsible for archiving the data once they are received on Earth.
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.
