Once complete, it obviated the need for the E-type objective of a medium Earth orbital test. The D-type mission was instead performed by Apollo 9; the F-type mission, Apollo 10, flew the CSM/LM spacecraft to the Moon for final testing, without landing. The G-type mission, Apollo 11, performed the first lunar landing, the central goal of the ...
Hadley–Apennine is a region on the near side of Earth's Moon that served as the landing site for the American Apollo 15 mission, the fourth crewed landing on the Moon and the first of the "J-missions", in July 1971. [1] [2] The site is located on the eastern edge of Mare Imbrium on a lava plain known as Palus Putredinis.
The first three lunar missions (Apollo 8, Apollo 10, and Apollo 11) used a free return trajectory, keeping a flight path coplanar with the lunar orbit, which would allow a return to Earth in case the SM engine failed to make lunar orbit insertion. Landing site lighting conditions on later missions dictated a lunar orbital plane change, which ...
Apollo 13 was slated to be the third landing on the moon after Apollo 8 (1968) and Apollo 12 (1969). Launched on April 11, 1970, the crew was led by commander Lovell, along with command module ...
Apollo 1, initially designated AS-204, was planned to be the first crewed mission of the Apollo program, [1] the American undertaking to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module .
NASA's Apollo Lunar Surface Journal (ALSJ) [1] records the details of each mission's period on the lunar surface as a timeline of the activities undertaken, the dialogue between the crew and Mission Control, and the relevant documentary records. Each photograph taken on the mission is catalogued there and each photographic sequence (i.e ...
1969 saw humanity step onto another world for the first time. On 20 July 1969, the Apollo 11 Lunar Module, Eagle, landed on the Moon's surface with two astronauts aboard. . Days later the crew of three returned safely to Earth, satisfying U.S. President John F. Kennedy's challenge of 25 May 1961, that "this nation should commit itself to achieving the goal, before this decade is out, of ...
Apollo 4 and Apollo 6 were "A" missions, tests of the Saturn V launch vehicle using an uncrewed Block I production model of the command and service module (CSM) in Earth orbit. Apollo 5 was a "B" mission, a test of the LM in Earth orbit. Apollo 7, scheduled for October 1968, would be a "C" mission, a crewed Earth-orbit flight of the CSM ...
