The Apollo program included three other crewed missions: Apollo 1 (AS-204) did not launch and its crew died in a ground-based capsule fire, while Apollo 7 and Apollo 9 were low Earth orbit missions that only tested spacecraft components and docking maneuvers. Apollo missions 18, 19, and 20 were canceled.
Apollo 9 (March 3–13, 1969) was the third human spaceflight in NASA's Apollo program.Flown in low Earth orbit, it was the second crewed Apollo mission that the United States launched via a Saturn V rocket, and was the first flight of the full Apollo spacecraft: the command and service module (CSM) with the Lunar Module (LM).
This is an alphabetical list of astronauts, people selected to train for a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. For a list of everyone who has flown in space, see List of space travelers by name. More than 600 people have been trained as astronauts.
On the way back to Earth, the Apollo 10 crew reached a speed of 24,791 miles per hour (39,897 km/h), the highest speed attained by a crewed vehicle. He returned to the Moon in April 1972 as commander of Apollo 16 , the fifth crewed lunar landing, becoming the ninth person to walk on the Moon and the second to fly to it twice.
The Earth-orbit test would become Apollo 9. [32] The crew who had been scheduled for Apollo 8, led by Jim McDivitt, became the Apollo 9 crew, [33] and Worden became part of that mission's support crew along with Mitchell and Jack Lousma. [34] Worden was named as backup command module pilot (CMP) for the Apollo 12 flight.
Although Deke Slayton (who was responsible for all flight assignments as Director of Flight Crew Operations) opined that Schweickart "would have been a logical lunar module pilot" on subsequent lunar missions—indeed, the standard rotation of the era would have placed him on the backup crew for Apollo 12 and the prime crew of Apollo 15 [13 ...
Two Apollo missions were failures: a 1967 cabin fire killed the entire Apollo 1 crew during a ground test in preparation for what was to be the first crewed flight; [6] and the third landing attempt on Apollo 13 was aborted by an oxygen tank explosion en route to the Moon, which disabled the CSM Odyssey's electrical power and life support ...
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. [77] 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 ...
