Skylab Skylab Skylab was a United States space station launched and operated by NASA, and occupied for about 24 weeks between May 1973 and February 1974 – the only space station the U.S. has operated exclusively. In 1979 it fell back to Earth amid huge worldwide media attention. Skylab included a workshop, a solar observatory, and other systems necessary for crew survival and scientific experiments. It was launched unmanned by a modified Saturn V rocket, with a weight of . Lifting Skylab into low earth orbit was the final mission and launch of a Saturn V rocket (famous for carrying the
Earth orbit rendezvous Earth orbit rendezvous Earth orbit rendezvous (EOR) is a potential methodology for conducting round trip human flights to the Moon, involving the use of space rendezvous to assemble, and possibly fuel, components of a translunar vehicle in low Earth orbit. It was considered and ultimately rejected in favor of lunar orbit rendezvous (LOR) for NASA's Apollo Program of the 1960s and 1970s. Three decades later, it was planned to be used for Project Constellation, until that program’s cancellation in October 2010. The Agena target vehicle (ATV) was used for testing Earth orbit rendezvous in the NASA Gemini Program. Gemini 6
