The four arrows in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image point to active dust devils captured around 2 p.m. local time on a flat plain west of the large basin, Schiaparelli. This image is located near 5.1°S, 348.9°W; and covers an area 3 km (1.9 mi) wide. The dust devil shadows point toward the northeast (upper right) because sunlight illuminates the scene from the southwest (lower 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.
