This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows v-shaped troughs in the Hephaestus Fossae region of Mars. Light-toned, windblown ripples reside in the very lowest parts of the troughs, as well as on the cratered upland outside the troughs. Boulders and other types of debris, which were derived from the layered rock exposed near the top of the troughs, are seen resting on the trough floors and perched on the sloping trough walls. |

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.
