|This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a tongue of debris at the base of the wall of a large crater in Terra Tyrrhena. The tongue is the combined product of landsliding and emplacement of crater ejecta—a ~3 km (1.9 mi) wide impact crater formed on the rim of the larger crater and, when it did, it caused the movement which created the tongue. About one third of the crater that caused this can be seen near the southwest (lower left) corner of the image.|

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.
