The Saturn V rocket took a dozen astronauts toward the Moon during 1969-1972 and is considered one of the greatest engineering achievements in history. This Saturn V is one of the three that are still in existsnce and is on loan to the Johnson Space Flight Center at Houston, Texas. The other two, also on loan from the Smithsonian Institution, are at the Kennedy Space Center, near Cape Canaveral, Florida, and at the U.S. Space and Rocket Center at Huntsville, Ala.
The first stage of this Saturn V is the S-I-C-14 and was scheduled for the Apollo 18 mission that was cancelled. The second stage is the S-II-15, that was a Skylab backup vehicle. The third stage is the S-IV-513, meant for the Apollo 18 mission. The spacecraft was also meant to fly on a later Apollo mission. This Saturn V is therefore the only existing Saturn V with all flyable stages. The rocket was transferred to the Smithsonian from the NASA Johnson Space Flight Center in 1978.
