Layers of wall rock, windblown drifts, and landslide deposits can be seen in this new view of the wall of Tithonium Chasma in the Valles Marineris trough system. The picture covers an area 3 kilometers (1.9 miles) wide by about 11 kilometers (6.8 miles) long and is illuminated from the lower right. The Mars Orbiter Camera on board the Mars Global Surveyor spacecraft acquired this dramatic picture in early April 1999.
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.
