This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows the lobate fronts of a large flow or series of smaller flow features in Kasei Valles. The rubbly surface of the flow has been interpreted to suggest that this might have been a mud flow, rather than a lava flow, but final determination will someday require a person to visit this landform "in the field." This picture is illuminated from the right and covers an area approximately 8 km (5 miles) wide near 15.7°N, 77.7°W.
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.
