The Apollo Moon Missions

The actual NASA's plan called for seven missions to the first manned moon landing. These were the missions A to G:Mission A: Unmanned test of Saturn V and Apollo spacecraft in Earth orbit (performed twice with Apollo 4 and Apollo 6).Mission B: Test of Unmanned Lunar Module (LM for Lunar Module) (performed with Apollo 5).Mission C: Manned test of the Apollo spacecraft in Earth orbit (using Apollo 7).Mission D: Testing the combination of the command module and lunar module in a low Earth orbit (originally planned as Apollo 8, Apollo 9 as renumbered, because a moon flight (Mission C ') was inserted as Apollo 8).Mission E: Testing the combination of the command module and lunar module in orbit distant geomagnetic (Mission was deleted, the mission team took over C ').Mission Q: Testing the combination of the command module and lunar module in lunar orbit (using Apollo 10).Mission G: First landing on the moon (using Apollo 11).Apollo 8 carried out with the first Mondumkreisung, Christmas 1968 was not actually provided by NASA and was inserted with the mission designation C 'between the C and D missions.Also unclear was the configuration of the first moon flight. The initial plans of the 1960s saw before a single spacecraft for landing on the moon and return to Earth, it was unclear whether Rendevouzmanöver and couplings of two spacecraft were possible. It soon became apparent that these plans were unrealistic. In particular, at the instigation of John C. Houbolt Therefore, the end of 1961 we went to a more complex, but optimized configuration of separate spacecraft. This allowed not only to manage with a single missile, but also allowed the optimization of individual components on their exact purpose. This concept will benefit from proposed Space Launch system unchanged.In addition, the emission H, I and J were planned:H mission: landing on the moon with advanced scientific experiments (performed with Apollo 12 and Apollo 13, Apollo 14th was not successful, Apollo 15 was also originally planned as a mission-H).Mission I: Manned flight in lunar orbit for research purposes, no landing intended. Concrete plans for missions I did not exist.J Mission: Landing on the moon with advanced scientific experiments, and the lunar rover (using Apollo 15, Apollo 16 and Apollo 17).
