The backup crew consisted of Pete Conrad as commander, Command Module Pilot Richard F. Gordon Jr. and Lunar Module Pilot Alan L. Bean. This crew flew as prime on Apollo 12 in November 1969. The support crew for Apollo9 consisted of Stuart A. Roosa, Jack R. Lousma, Edgar D. Mitchell and Alfred M. Worden. Lousma was not an original member of the Apollo9 support crew, but was assigned after Fred W. Haise Jr. was moved to the position of backup lunar module pilot on Apollo 8—several astronauts were shifted in the wake of Michael Collins being removed from the Apollo8 prime crew because of treatment for bone spurs.
