on the Moon on the
Apollo 15 mission Although training continued until September 1967, Shepard assigned them to six branches of his office on October 3, 1966. Engle, Lousma, Pogue and Weitz were assigned to the Apollo Applications Branch, which was headed by
Group 3 member
Alan Bean, with
Bill Anders as his deputy. Brand, Evans, Mattingly, Swigert and Worden were assigned to the
CSM Block II Branch, which was headed by
Group 2 member
Pete Conrad, with Group 3 member
Richard Gordon as his deputy. Bull, Carr, Haise, Irwin and Mitchell were assigned to Group 2 member
Neil Armstrong's
LM/
LLRV/
LLRF Branch. Givens was assigned to John Young's Pressure Suits/
PLSS Branch; Lind and McCandless were to
Owen Garriott's Experiments Branch; and Duke and Roosa to
Frank Borman and C.C. Williams's Boosters/Flight Safety Panels Branch. In earlier groups, the senior astronaut had assumed the role of command module pilot while the more junior was the lunar module pilot, but the Nineteen were divided into CSM and LM specialists. Slayton asked each of the Nineteen which speciality he preferred, but made the final decision himself. This early division of assignments would have a profound effect on their subsequent careers. Brand, Evans, Givens, Mattingly, Pogue, Roosa, Swigert, Weitz and Worden became CSM specialists, while Bull, Carr, Duke, Engle, Haise, Irwin, Lind, Lousma, McCandless and Mitchell became LM specialists. 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. Support crew assignments soon became the stepping stone to assignment to a backup, and then a prime crew. For
Apollo 1, which would not carry a LM, the support crew consisted of three CSM specialists: Givens, Evans and Swigert. For Apollo 2, which would test the LM, two LM specialists, Haise and Mitchell, were assigned to the support crew, along with Worden, a CSM specialist. For Apollo 3, the support crew consisted of LM specialists Bull and Carr, and CSM specialist Mattingly. The schedule was disrupted by the deaths of
Gus Grissom,
Ed White and
Roger Chaffee in the Apollo 1 fire on January 27, 1967, Givens in a car crash on June 6, and C.C. Williams in an air crash on October 5. Pogue replaced Givens on the first support crew, which now supported
Apollo 7. conducts an EVA during the
STS-41-B mission Haise became the first of the Nineteen to be promoted to a backup crew assignment when he joined Armstrong's backup crew for the
Apollo 9 mission, followed by Mitchell, who joined
Gordon Cooper's backup crew for
Apollo 10. They were replaced by Lousma and Roosa, respectively, while Brand replaced Bull, who had been forced to resign due to ill-health. Apollo 8 and 9 subsequently exchanged prime, backup and support crews, so Brand, Carr and Mattingly became the support crew of Apollo 8, and Lousma, Roosa and Worden became that of Apollo 9. Originally, Mitchell was in line to be the first member of the group to fly in space, but due to the swap of
Apollo 13 and
Apollo 14 crews, Swigert and Haise became the first. Starting with Apollo 13, each crew consisted of a senior astronaut from Group 1, 2 or 3, and a CM and LM specialist from the Nineteen, except that
geologist Harrison Schmitt from Group 4 was designated as the Lunar Module pilot of Apollo 18, and then took Engle's place on
Apollo 17 when Apollo 18 was canceled. Of the 24 men who flew to the Moon on Apollo missions, nine were from the Nineteen, the most of any group. Three of them—Mitchell, Irwin and Duke—walked on the Moon, and Worden, Mattingly and Evans conducted deep space EVAs on the way back from the Moon. Four more of the Nineteen flew on the three Skylab missions, and also performed EVAs. Brand flew as command module pilot on the Apollo-Soyuz Test Project in July 1975, becoming the last of the Nineteen to fly in an Apollo spacecraft. With no more space flights in prospect, ten of the Nineteen left NASA in the 1970s. The seven that remained would all fly Space Shuttle missions. Veteran astronauts Engle, Lousma, Mattingly, Brand and Weitz commanded STS-2, STS-3, STS-4, STS-5 and STS-6 respectively. McCandless was the only one of the Nineteen to perform an EVA from a shuttle, which he did as a mission specialist on his first space flight, the STS-41B mission in February 1984. Lind had to wait even longer; flying in space for the first time as a mission specialist on STS-51B in April and May 1985, nineteen years after he was first selected as an astronaut in April 1966, and fifteen after Haise and Swigert had become the first of the Nineteen to fly on Apollo 13 in April 1970. The last mission flown by any of the Nineteen was STS-35 in December 1990, which was commanded by Brand, who became the last member of the group to leave the Astronaut Office when he departed in 1992. Between them, the Nineteen had flown 29 Space Shuttle missions. == Notes ==
