Apollo 12 was the second manned mission to the moon and the only one that boasted an all-Navy crew of Comdr. Charles “Pete” Conrad, Comdr. Richard F. “Dick” Gordon, and Comdr. Alan L. Bean.
Apollo 12 lifted off on 14 November and on 19 November Conrad and Bean became the third and fourth humans to walk on the moon.
The crew of Apollo 12 boated many accomplishments, including: the first precision manual moon landing; the first time the pilot maneuvered the Command Module into a different orbiting trajectory, a requirement for future missions; an extended visit to the lunar service–almost three times as long as Apollo 11–including two separate moonwalks and recovery of equipment from an earlier unmanned probe; and finally, the first deployment of an automated scientific analysis package, which remained operational for eight years and provided a wealth of information.
The excellent performance of the spacecraft, the crew, and the support personnel ranked this “all-Navy” mission as one of the most successful in NASA history.
