Skylab 2: mission accomplished
Having repaired and secured the damaged Skylab over the course of three spacewalks, the space station’s first three-man crew leaves the station and returns to Earth after 28 days in space, experiencing gravity after nearly a month of zero-G.
The first Skylab crew’s stay in space sets a new record, twice as long as the previous longest American manned spaceflight, Gemini 7 in 1965.
