An astronaut's snapshot of the Moon
===================================

Apollo 17 astronauts Dr. H. Jack Schmitt and Gene Cernan took this image of the Moon's Taurus-Littrow 
valley. The view shows the lunar roving vehicle near the rim of Shorty crater. In the distance are the 
mountain-like massifs that define the Taurus-Littrow valley. This region marks the last time ? December 
1972 ? that humans walked and drove on the Moon's surface.
