Here’s an exceptionally beautiful image taken by the HiRISE camera on the Mars Reconnaissance Orbiter showing rippling dunes within a crater on Mars’ southern hemisphere.
The way the dunes are lit reminds me of a Salvador Dali painting, the central area reminiscent of the lower part of a human face. The brightest areas are most likely carbon dioxide frost – dry ice – as the region was in winter when this image was taken.
