                         [3]Apollo 17 Crew, [4]NASA

   Explanation: [5]Fifty three years ago, in December of 1972, Apollo 17
   astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours
   [6]on the Moon exploring the [7]Taurus-Littrow valley, while colleague
   Ronald Evans [8]orbited overhead. This [9]snapshot from another world
   was taken by Cernan as he and Schmitt [10]roamed the lunar valley's
   floor. The image shows Schmitt next to the [11]lunar rover parked at
   the southeast rim of [12]Shorty Crater. That location is [13]near the
   spot where geologist Schmitt discovered [14]orange lunar soil. The
   Apollo 17 crew returned with 110 kilograms of [15]rock and soil
   samples, more than was returned from any of the other lunar landing
   sites. [16]And for now, Cernan and Schmitt are the last to walk [17]on
   the Moon.
