This is a Mars Orbiter Camera view of the cratered uplands located between the Amenthes Fossae and Hesperia Planum. This ancient, cratered surface sports a covering of windblown dunes and ripples oriented in somewhat different directions. The dunes are bigger and their crests generally run east-west across the image. The ripples are smaller and their crests run in a more north-south direction. The pattern they create together makes some of the dunes almost appear as if they are giant millipedes!This picture covers an area only 3 kilometers (1.9 miles) wide. Illumination is from the top.

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, CA. 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, CA and Denver, CO.
