Today's Image of Mars shows a portion of the dunes in Richardson Crater, a 55km diameter crater in the south polar region of Mars. This image was taken as the dunes began to thaw and the carbon dioxide ice started to sublimate. You can see this in the dark patches where the ice has already sublimated.
This image was taken in 2009 by HiRISE aboard the Mars Reconnaissance Orbiter. Click image to see the original captioned image.
