V-Shaped Dune Field Formation on Mars
In this space wallpaper of a dune field on Mars in a large crater near Mawrth Vallis, some of the dunes appear to be in a V-shaped formation. For dune fields, the spacing of individual dunes is a function of sand supply, wind speed, and topography. (Image credit: NASA/JPL-Caltech/Univ. of Arizona)

In this space wallpaper of a dune field on Mars in a large crater near Mawrth Vallis, some of the dunes appear to be in a V-shaped formation. For dune fields, the spacing of individual dunes is a function of sand supply, wind speed, and topography. This image was acquired by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter on Dec. 30, 2013.
