Ares 3 Landing Site: The Martian Revisited

This close-up from the Mars Reconnaissance Orbiter's HiRISE camera shows weathered craters and windblown deposits in southern Acidalia Planitia. While shown here in blue, to the human eye, the area would likely appear grey or reddish. This terrain is also known as the landing site for the fictional Ares 3 mission in the novel 'The Martian'.
