There would be five more successful lunar landing missions, and one unplanned lunar swing-by, Apollo 13. The last men to walk on the moon, astronauts Eugene Cernan and Harrison Schmitt of the Apollo 17 mission, left the lunar surface on December 14, 1972. The Apollo program was a costly and labor intensive endeavor, involving an estimated 400,000 engineers, technicians, and scientists, and costing $24 billion (close to $100 billion in today’s dollars). The expense was justified by Kennedy’s 1961 mandate to beat the Soviets to the moon, and after the feat was accomplished ongoing missions lost their viability.
