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 ...
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 ...
Orbital photo of the Hadley-Apennine site; Apollo 15 landing site is marked with a circle. 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.
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 ...
English: Apollo 17 flight trajectory from liftoff to end of S-IVB first burn. - Altitude is given above Fischer Ellipsoid. E.g. at time 400s: EPO altitude 172km = 6545km geocentric distance = 167km above a spherical Earth of radius 6378.1 km
Despite its historic nature, the primary purpose of Apollo 11 was simple; to perform a manned lunar landing and return [3].All other aspects were considered as bonuses, including the Extravehicular Activity/EVA on the surface (AKA Moonwalk) which was kept to the barest minimum of placing a few experimental devices, grabbing a few rocks, and taking a few photographs.
NASA's Apollo Lunar Surface Journal (ALSJ) [1] records the details of each mission's time 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 is also recorded.
