The Apollo program included both manned and unmanned space missions, flown by NASA between 1961 and 1975. They culminated with a series of manned Moon landings between 1969 and 1972. ==Launch vehicles== The Apollo program used four types of launch vehicles: *Little Joe II - unmanned suborbital launch escape system development. *Saturn I - unmanned suborbital and orbital hardware development. *Saturn IB - preparatory unmanned missions, and Apollo 7, the first manned (Earth orbit) mission. *Saturn V - unmanned and manned earth orbit and lunar missions. The Marshall Space Flight Center, which designed the Saturn rockets, referred to the flights as Saturn-Apollo (SA), while Kennedy Space Center referred to the flights as Apollo-Saturn (AS). This is why the unmanned Saturn 1 flights are referred to as SA and the unmanned Saturn 1B are referred to as AS. Dates given below are dates of launch. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of Apollo missions」の詳細全文を読む スポンサード リンク
