This week in 1966, NASA’s Marshall Space Flight Center successfully static-fired S-IC-2, the first stage of the second Saturn V flight vehicle. The stage was powered by five F-1 engines, each capable of producing 1.5 million pounds of thrust. The S-IC-2 was one of the first two flight models of the S-IC stage and was used on the Apollo 6 mission. Here, the S-IC-T, a static firing test stage, is installed and awaits the first firing of all five F-1 engines at the Marshall static test stand. 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.
