Record flight duration. Final Skylab mission; included observation and photography of Comet Kohoutek among numerous experiments. Rebellion by crew against NASA Ground Control overtasking led to none of the crew ever flying again.

AKA: Skylab. Launched: 1973-11-16. Returned: 1974-02-08. Number crew: 3 . Duration: 84.05 days. Location: National Air and Space Museum (Smithsonian Institution), Washington, DC.

Final Skylab mission; included observation and photography of Comet Kohoutek among numerous experiments. Completed 1,214 Earth orbits and four EVAs totaling 22 hours, 13 minutes. Increased manned space flight time record by 50%. Rebellion by crew against NASA Ground Control overtasking led to none of the crew ever flying again. Biological experiments included two Mummichog fish (Fundulus heteroclitus).

The space vehicle consisted of a modified Apollo CSM and a Saturn IB launch vehicle. All launch phase events were normal, and the CSM was inserted into a 150.1- by 227.08-km orbit. The rendezvous sequence was performed according to the anticipated timeline. Stationkeeping was initiated about seven and one-half hours after liftoff, and hard docking was achieved about 30 minutes later following two unsuccessful docking attempts. Planned duration of the mission was 56 days, with the option of extending it to a maximum of 84 days.
