On December 17, 1972, a Saturn V rocket streaks through the night, carrying the Apollo 17 crew. The astronauts were the last humans to explore the moon. Leaving the lunar surface, Commander Gene Cernan said, "We leave as we came, and, God willing, we shall return, with peace and hope for all mankind." The three-stage Saturn V stood over 36 stories tall and had a cluster of five first-stage engines fueled by liquid oxygen and kerosene capable of producing 7.5 million pounds (3.4 million kilograms) of thrust.
