On January 10th, 1962 NASA released plans to build a C-5 rocket. A year later, this rocket was picked to fly to the moon and was named the Saturn V. The first flight of a Saturn V rocket was an unmanned flight in 1967, and subsequently 12 more rockets were launched between 1967 and 1973, carrying Apollo missions and the Skylab space station. Each rocket took different amounts of time to make, but the first one took about five years of research and development.
