This April 2004 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a dark wind streak on the lee (downwind) side of a small meteor impact crater in western Daedalia Planum. The substrate in this region consists of large lava flows (larger than the image shown here). The winds responsible for the streak came from the east/northeast (right). This picture is located near 15.4°S, 138.1°W, and covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene 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.
