AKA: Skylab. Launched: 1973-07-28. Returned: 1973-09-25. Number crew: 3 . Duration: 59.46 days. Location: NASA Lewis Research Center, Cleveland, OH.
Continued maintenance of the Skylab space station and extensive scientific and medical experiments. Completed 858 Earth orbits and 1,081 hours of solar and Earth experiments; three EVAs totaled 13 hours, 43 minutes.
The space vehicle, consisting of a modified Apollo command and service module payload on a Saturn IB launch vehicle, was inserted into a 231.3 by 154.7 km orbit. Rendezvous maneuvers were performed during the first five orbits as planned. During the rendezvous, the CSM reaction control system forward firing engine oxidizer valve leaked. The quad was isolated. Station-keeping with the Saturn Workshop began approximately 8 hours after liftoff, with docking being performed about 30 minutes later.

The Skylab 3 space vehicle was moved to KSC Launch Complex 39, Pad B, on 11 June in preparation for launch. The space vehicle consisted of a Saturn IB launch vehicle S-IB-207 first stage, S-IVB-207 second stage, and a S-IU-208 instrument unit; a CSM; and a spacecraft lunar module adapter.

Twice-weekly experiment planning meetings were being instituted for the 59-day Skylab 3 mission. The purpose of the meetings was to formulate a balanced set of experiment requirements for each upcoming week based on a consideration of plans for the remainder of the mission.
Continued maintenance of the Skylab space station and extensive scientific and medical experiments. Installed twinpole solar shield on EVA; performed major inflight maintenance; doubled record for length of time in space. Completed 858 Earth orbits and 1,081 hours of solar and Earth experiments; three EVAs totalled 13 hours, 43 minutes.
The space vehicle, consisting of a modified Apollo command and service module payload on a Saturn IB launch vehicle, was inserted into a 231.3 by 154.7 km orbit. Rendezvous maneuvers were performed during the first five orbits as planned. During the rendezvous, the CSM reaction control system forward firing engine oxidizer valve leaked. The quad was isolated. Station-keeping with the Saturn Workshop began approximately 8 hours after liftoff, with docking being performed about 30 minutes later.
The Skylab 3 crewmen experienced motion sickness during the first three visit days. Consequently, the Orbital Workshop activation and experiment implementation activities were curtailed. By adjusting the crew's diet and maintaining a low workload, the crew was able to complete the adjustment to space flight in five days, after which flight activities returned to normal. On 25 September, the command module was reactivated and the crew performed the final OWS closeout. Following undocking and separation, the command module entered the atmosphere and landed in the Pacific Ocean approximately 300 km southwest of San Diego. Splashdown was at 6:20 p.m. EDT. The recovery ship, U.S.S. New Orleans, retrieved the command module and crew 42 minutes after landing. The total flight time was 1427 hours 9 minutes 4 seconds. Additional Details: here....
On 2 August the service module reaction control system engines were inhibited, and the isolation valves closed because of another leak. Acceptable control modes and deorbit and entry procedures were defined, consistent with the constraints imposed by the two reaction control system problems.
Installed second sunshade. Replaced solar camera film cartridges. During EVA by crew members of Skylab 3, a twin-boom sunshade, developed by MSFC, was deployed over the parasol of the OWS. A redesigned and refined thermal parasol had been launched with Skylab 3. However, its use would have required jettisoning the parasol deployed by crew members of Skylab 2, with the possibility of creating the same thermal problems that existed on the OWS prior to the parasol deployment. Following erection of the twin-pole sunshade, the cabin temperature stayed at a comfortable 293-297 K (67.7°F-74.9°F).
Influenced by the stranded Skylab crew portrayed in the book and movie 'Marooned', NASA provided a crew rescue capability for the only time in its history. A kit was developed to fit out an Apollo command module with a total of five crew couches. In the event a Skylab crew developed trouble with its Apollo CSM return craft, a rescue CSM would be prepared and launched to rendezvous with the station. It would dock with the spare second side docking port of the Skylab docking module. During Skylab 3, one of the thruster quads of the Apollo service module developed leaks. When the same problem developed with a second quad, the possibility existed that the spacecraft would not be maneuverable. Preparation work began to fit out a rescue CSM, and astronauts Vance Brand and Don Lind began preparations to rescue astronauts Bean, Garriott, and Lousma aboard the station. However the problem was localized, work arounds were developed, and the first space rescue mission was not necessary. The Skylab 3 crew returned successfully in their own Apollo CSM at the end of their 59 day mission.
An ad hoc committee to analyze the vestibular problems which occurred in previous manned space flights. An ad hoc committee was established to analyze the vestibular problems which occurred in previous manned space flights and to make recommendations concerning prevention and control on future flights. Particular emphasis was placed on the experiences of the Skylab 3 crew. As a result of the committee meeting, it was recommended that the crewmen of SL-4 take anti-motion-sickness medication immediately upon orbital insertion and follow this with periodic doses for the first three days of flight.
Among the items covered were a plan for measuring both the pre- and postflight cardiac outputs of the SL-4 crew; elimination of all activities in the deactivation sequence not absolutely required; and a plan for accommodation of the circadian shift necessary for missions of various durations.
