This week in 1964, hydrostatic testing of the Saturn V S-IC — the first stage test fuel tank — was successfully conducted at NASA’s Marshall Space Flight Center. The S-IC stage was powered by five F-1 engines, which used liquid oxygen and kerosene as its propellants. When completely assembled, the Saturn V S-IC stage was 138 feet tall, 33 feet in diameter, and capable of delivering 7.5 million pounds of thrust from its five engines. Now through December 2022, NASA will mark the 50th anniversary of the Apollo Program that landed a dozen astronauts on the Moon between July 1969 and December 1972, and the first U.S. crewed mission — Apollo 8 — that circumnavigated the Moon in December 1968. The NASA History Program is responsible for generating, disseminating, and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA’s activities in aeronautics and space.
