Lunar Rover Map, Apollo 17
q The last men to walk on the moon used this map in the lunar rover to find something nobody was expecting: patches of orange soil among the dark gray dust of crater Shorty. (The orange was vivid enough that even pilot Ron Evans could see it from the orbiting Command Module.) In the mission transcript, an incredulous Commander Gene Cernan asks, “How can there be orange soil on the moon?” Answer: Shorty is an impact crater, and the impact uncovered a layer of volcanic glass. Luckily, the mission included Harrison “Jack” Schmitt, the only geologist to be sent to the moon. He reacted to the discovery “like a boy at Christmas,” recalled CAPCOM Robert Parker. The map belongs to Jim Ruddy, who runs the website Moon Collector ( ).
