Warrego Valles is a suite of branching valleys located in the martian southern hemisphere near 43°S, 92°W. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows some of the valleys of this system. They are old and have been partially filled with material that today forms an eroded, rugged texture. Prior to the MGS mission, it had been hoped that MOC would show evidence as to how valleys such as those in the Warrego system formed, but many of the valleys turned out to have been modified by later processes that obscure the original geologic features related to their origin. This image is illuminated from the upper left.
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.
