This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a variety of dark sand dune patterns and shapes in the north polar region of Mars. Small, aligned dunes in some cases have merged to form elongated dunes. These features are located near 76.4°N, 272.9°W. The image covers an area approximately 3 km (1.9 mi) across and is illuminated by sunlight from the 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.
