Apollo 11 as CMP, and Haise as LMP. Anders had flown with Lovell on Apollo 8. In early 1969, he accepted a job with the National Aeronautics and Space Council effective August 1969, and announced that he would retire as an astronaut at that time. Ken Mattingly was moved from the support crew into parallel training with Anders as backup CMP in case Apollo 11 was delayed past its intended July launch date, at which point Anders would be unavailable. Lovell, Haise, and Mattingly were later assigned as the prime crew of Apollo 13. During Projects Mercury and Gemini, each mission had

The "Apollo Manned Survey Mission" proposed an Earth-observation science module also based on the LM ascent stage, and would also have been launched using a S-IVB vehicle into a high-inclination orbit. It was also proposed that a surplus Saturn V would launch a manned lunar survey mission to establish suitable sites for later manned landings. The wet workshop space station concept provided for a low-budget Earth orbiting station. The original plan, as proposed by Wernher von Braun, used the S-II stage as the primary structure of the station, with the area normally filled by the S-IVB stage replaced
