Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                 Ares 3 Landing Site: The Martian Revisited
               [3]HiRISE, [4]MRO, [5]LPL (U. Arizona), [6]NASA

   Explanation: [7]This close-up from the Mars Reconnaissance Orbiter's
   HiRISE camera shows weathered craters and windblown deposits in
   southern [8]Acidalia Planitia. A striking shade of blue in standard
   HiRISE image colors, to the human eye the area would probably look grey
   or a little reddish. But human eyes have not gazed across this terrain,
   unless you count the eyes of NASA astronauts in the scifi novel [9]The
   Martian by Andy Weir. The novel chronicles the adventures of Mark
   Watney, an astronaut stranded at the fictional Mars mission Ares 3
   landing site corresponding to the coordinates of this cropped HiRISE
   frame. For scale Watney's 6-meter-diameter habitat at the site would be
   about 1/10th the diameter of the large crater. [10]Of course, the Ares
   3 landing coordinates are only about 800 kilometers north of the (real
   life) Carl [11]Sagan Memorial Station, the 1997 [12]Pathfinder landing
   site.
