Dune
In this image 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.
