Arkhangelsky Crater Dunes
Date: 28 Sep 2010
These dunes lie within Arkhangelsky crater, which is located in the Martian southern hemisphere. This type of dune is known as "barchan." Barchan dunes have a steep slip face nestled between two downwind pointing "horns." If you look closely you may be able to see the tracks of Martian dust devils on the dunes and crater floor.

JPL, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace & Technologies Corporation and is operated by the University of Arizona.
