Skylab 3
With the first Skylab crew having salvaged the first American space station, the second crew – designated Skylab 3 – lifts off for another long-term stay in space. Alan Bean, Jack Lousma and Owen Garriott spend 59 days aboard Skylab, performing a spacewalk to conduct further repairs to their damaged space station, investigating the effects of long-duration weightlessness and space travel on the human body, and observing the sun through Skylab’s solar telescope system. A thruster leak in the Apollo command/service module forces NASA to consider a rescue mission.
