It has now been 50 years since astronauts last launched to the moon.
NASA's Apollo 17 mission lifted off on Dec. 7, 1972, sending Gene Cernan, Harrison Schmitt and Ronald Evans toward Earth's nearest neighbor. The trio arrived in orbit around the moon three days later.
Evans remained in lunar orbit aboard the mission's command module, named America. Cernan and Schmitt took the lunar module Challenger to the surface, touching down on the southeastern rim of the moon's Mare Serenitatis ("Sea of Serenity") on Dec. 11.
