Apollo 20 hardware reassigned to Skylab

NASA formally cancels the planned Apollo 20 mission to the moon’s Copernicus crater in order to begin converting the upper stage of the mission’s Saturn V rocket into the Skylab space station, to be launched in the early 1970s. Construction of the Apollo command/service module and lunar module scheduled to fly this mission was halted before either vehicle was completed. The crew would have consisted of Stu Roosa, Paul Weitz and Jack Lousma; ironically, Weitz was transferred to the first Skylab crew, while Lousma was part of the second Skylab crew. Both later flew on shuttle missions.
