2 January 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a dark sand dune field in a crater in the Noachis Terra region. Martian dunes are darker than their typical terrestrial counterparts because they contain minerals with a higher abundance of iron and magnesium, and somewhat lower amounts of silica.
