Apollo 15 rollout
This image shows the Apollo 15 Saturn V getting wheeled out of the Vehicle Assembly Building prior to launch on July 26, 1971. In 1969, Apollo 11 became the first crewed mission to the lunar surface, and it was followed by five additional crewed landings, namely Apollo 12, 14, 15, 16, and 17. Three-stage Saturn Vs were used to launch Apollo missions, but a modified two-stage Saturn V rocket launched NASA’s Skylab Orbital Workshop in May 1973.
