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
Apollo 1 bearing on the accident. Manned Apollo flights were suspended for 20 months while the command module's hazards were addressed. However, the development and unmanned testing of the lunar module (LM) and Saturn V Moon rocket continued. The Saturn IB launch vehicle for Apollo 1, AS-204, was used for the first LM test flight, Apollo 5. The first successful manned Apollo mission was flown by Apollo 1's backup crew on Apollo 7 in October 1968. AS-204 was to be the first manned test flight of the Apollo command and service module (CSM) to Earth orbit, launched on a Saturn IB rocket.
