Title: Buzz Aldrin
Content:  Apollo8 crew. When Collins recovered he joined Armstrong's crew as CMP. In the meantime, Fred Haise filled in as backup LMP, and Aldrin as backup CMP for Apollo 8. While the CMP usually occupied the center couch on launch, Aldrin occupied it rather than Collins, as he had already been trained to operate its console on liftoff before Collins arrived. Apollo11 was the second American space mission made up entirely of astronauts who had already flown in space, the first being Apollo 10. The next would not be flown until STS-26 in 1988. Deke Slayton, who was responsible for astronaut flight assignments, gave Armstrong the option to replace 
Title: Zhai Zhigang
Content:  commander, on 17 September 2008. On 25 September 2008, at 21:10 CST, they launched into space as the first three-man crew for China, China's third human spaceflight mission. On 27 September 2008, Zhai became the first Chinese astronaut to spacewalk, completely outside the craft. Fellow crew member Liu Boming stood by at the airlock and could be seen straddling the portal. Zhai successfully completed his spacewalk at 18:25 CST. Zhai wore the Chinese developed Feitian space suit, while Liu wore the Russian derived Orlan-M space suit. Zhai was selected as commander to fly on the Shenzhou 13 alongside Wang Yaping and Ye Guangfu as his second spaceflight mission to the Tiangong space station. On 7 November 2021, Zhai carried out his second spacewalk alongside Wang who became China's first woman to perform a spacewalk.
Title: Apollo 8
Content:  The backup crew assignment of Neil Armstrong as Commander, Lovell as CMP, and Buzz Aldrin as LMP for the third crewed Apollo flight was officially announced at the same time as the prime crew. When Lovell was reassigned to the prime crew, Aldrin was moved to CMP, and Fred Haise was brought in as backup LMP. Armstrong would later command Apollo11, with Aldrin as LMP and Collins as CMP. Haise served on the backup crew of Apollo11 as LMP and flew on Apollo13 as LMP.
Title: Apollo 8
Content:  The initial crew assignment of Frank Borman as Commander, Michael Collins as Command Module Pilot (CMP) and William Anders as Lunar Module Pilot (LMP) for the third crewed Apollo flight was officially announced on November 20, 1967. Collins was replaced by Jim Lovell in July 1968, after suffering a cervical disc herniation that required surgery to repair. This crew was unique among pre-Space Shuttle era missions in that the commander was not the most experienced member of the crew: Lovell had flown twice before, on Gemini VII and Gemini XII. This would also be the first case of a commander of a previous mission (Lovell, Gemini XII) flying as a non-commander. This was also the first mission to reunite crewmates from a previous mission (Lovell and Borman, Gemini VII). As of 2021, all three Apollo 8 astronauts remain alive.
Title: Zhai Zhigang
Content:  Zhai Zhigang (born 10 October 1966) is a Chinese major general of the People's Liberation Army Strategic Support Force (PLASSF) in active service as a People's Liberation Army Astronaut Corps (PLAAC) taikonaut. During the Shenzhou 7 mission in 2008, he became the first Chinese citizen to carry out a spacewalk. He was a People's Liberation Army Air Force (PLAAF) fighter pilot.
Title: Buzz Aldrin
Content:  Lovell and Aldrin were assigned to an Apollo crew with Neil Armstrong as Commander, Lovell as Command Module Pilot (CMP), and Aldrin as Lunar Module Pilot (LMP). Their assignment as the backup crew of Apollo 9 was announced on November 20, 1967. Due to design and manufacturing delays in the lunar module (LM), Apollo 8 and Apollo9 swapped prime and backup crews, and Armstrong's crew became the backup for Apollo 8. Under the normal crew rotation scheme, Armstrong was expected to command Apollo 11. Michael Collins, the CMP on the Apollo8 prime crew, required surgery to remove a bone spur on his spine. Lovell took his place on 
Title: Zhai Zhigang
Content:  In 1996, Zhai was selected to trial for the taikonaut program and was selected to be the first group of fourteen in 1998. He was one of three members of the final group to train for the Shenzhou 5 flight. Yang Liwei was picked for the flight, with Zhai Zhigang ranked second ahead of Nie Haisheng. Zhai was one of the six taikonauts in the final training for Shenzhou 6. The Ta Kung Pao newspaper had reported that Zhai Zhigang and Nie Haisheng were the leading pair, after having been in the final group of three for Shenzhou 5. However, Zhai had been paired with Wu Jie during training. Fei Junlong and Nie Haisheng flew the flight. Zhai, along with Liu Boming and Jing Haipeng was selected for prime crew on Shenzhou 7, with Zhai 
Title: Apollo 8
Content:  During Projects Mercury and Gemini, each mission had a prime and a backup crew. For Apollo, a third crew of astronauts was added, known as the support crew. The support crew maintained the flight plan, checklists, and mission ground rules, and ensured that the prime and backup crews were apprised of any changes. The support crew developed procedures in the simulators, especially those for emergency situations, so that the prime and backup crews could practice and master them in their simulator training. For Apollo8, the support crew consisted of Ken Mattingly, Vance Brand, and Gerald Carr. The capsule communicator (CAPCOM) was an astronaut at the Mission Control Center in Houston, Texas, who was the only person who communicated directly with the flight crew. For Apollo8, the CAPCOMs were Michael Collins, Gerald Carr, Ken Mattingly, Neil Armstrong, Buzz Aldrin, Vance Brand, and Fred Haise. The mission control teams rotated in three shifts, each led by a flight director. The directors for Apollo8 were Clifford E. Charlesworth (Green team), Glynn Lunney (Black team), and Milton Windler (Maroon team).
Title: Gemini 9A
Content:  The promotion of Stafford and Cernan from backup to prime crew meant that a new backup crew was required. Jim Lovell and Buzz Aldrin were originally the backup crew for Gemini 10. This is significant as the standard crew rotation meant that a spot on the backup crew of Gemini 10 would have placed Buzz Aldrin on the prime crew of the non-existent mission after Gemini 12 (the crew rotation usually meant that after serving on a backup crew, an astronaut could expect to skip two missions and then be on a prime crew). Being moved up to the backup crew of Gemini 9 meant that Aldrin flew as part of the prime crew on Gemini 12, which played a major part in his selection for the Apollo 8 backup and Apollo 11 prime crews, ultimately making him the second human on the Moon.
Title: NASA Astronaut Group 8
Content:  first mission, STS-1, when Ed Gibson retired. Once the OFTs were completed, the Space Shuttle could commence its designated role of launching satellites. The pilots of the STS-1 and STS-2, Bob Crippen and Dick Truly, were given command of STS-7 and STS-8 respectively, with TFNGs Rick Hauck and Dan Brandenstein assigned as their pilots. This established a pattern that would continue of a pilot astronaut flying as a pilot on one mission, and then as a commander on the next. NASA management wanted a woman and an African American flown as soon as possible, so George Abbey selected Sally Ride and Guion Bluford. Chris Kraft thought that this decision should be considered further, so Bob Crippen, Carolyn Huntoon, Leonard S. Nicholson
