MGS MOC Release No. MOC2-154, 19 July 1999
The scoured floor of Hrad Vallis is shown in the Mars Global Surveyor Mars Orbiter Camera (MOC) image above. This valley is located on the the other side of the planet relative to the Pathfinder site. Hrad Vallis is one of several channel systems that are found just west of the Elysium volcanoes (e.g., Elysium Mons--see MOC2-57). The image shown here is illuminated from the right and was obtained on July 20, 1998.
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.
