A Saturn V rocket emerges from the massive Vehicle Assembly Building, still the largest single-story structure in the world.
Following numerous modifications and upgrades, Juno II became Juno V, a colossal multi-stage “Super-Jupiter” rocket that was designed but never produced due to the shift of space responsibilities from the Army to NASA. Between 1958 and 1961, NASA inherited virtually all of the Army’s space research, including the ballistic missile program, facilities at Redstone Arsenal, the Redstone rockets, the Explorer satellite program, and even space race mastermind Werner von Braun himself. His entire staff followed. Some 6500 people departed the Army Ballistic Missile Program for von Braun’s civilian spaceflight operation at NASA. The Juno rocket also followed von Braun. In 1960 it was renamed Saturn.
