NASA was established by law on 29 July 1958. One day later, the 50th Redstone rocket was successfully launched from Johnston Atoll in the south Pacific as part of Operation Hardtack I. Two years later, NASA opened the Marshall Space Flight Center at Redstone Arsenal in Huntsville, and the Army Ballistic Missile Agency (ABMA) development team led by von Braun was transferred to NASA. In a face-to-face meeting with Herb York at the Pentagon, von Braun made it clear he would go to NASA only if development of the Saturn were allowed to continue. Von Braun became the center's first director on 1 July 1960 and held the position until 27 January 1970.
