What is the Saturn V?

The Saturn V was designed by NASA's Marshall Center under the direction of Wernher von Braun with a single goal: to meet the commitment of landing a human being on the Moon before 1970. It was a three-stage vehicle. The first stage, S-IC, burned kerosene and liquid oxygen in five F-1 engines, the most powerful single-chamber liquid-propellant engines ever to fly. The second stage, S-II, and the third, S-IVB, used liquid hydrogen and oxygen with J-2 engines; the S-IVB reignited in orbit for trans-lunar injection. Each stage was built by a different contractor: Boeing built the S-IC, North American the S-II, and Douglas the S-IVB. At the top sat the command and service module and the lunar module.

At 110.6 m tall, 10.1 m in diameter, and about 2,900 t on the pad, it could place roughly 140 t into low Earth orbit or send about 48 t toward the Moon. Its first flight, Apollo 4, lifted off on November 9, 1967, uncrewed, from Launch Complex 39A at the Kennedy Space Center. Apollo 8 flew it with astronauts for the first time in December 1968, and Apollo 11 carried Armstrong, Aldrin, and Collins in July 1969. In total, 13 units flew: two test flights, ten crewed Apollo missions, and, in May 1973, a two-stage version that launched the Skylab space station.

No rocket exceeded its payload capacity for more than fifty years. Three complete examples survive, at the Kennedy Space Center, the Johnson Space Center in Houston, and the U.S. Space & Rocket Center in Huntsville. Its cryogenic-stage architecture and vertical integration procedures directly inspired the Space Launch System, the Artemis program's lunar rocket, and the F-1 remains a benchmark for high-thrust engines.
