 Due to a NASA management error, crewed Skylab mission patches were designed in conflict with the official mission numbering scheme.  Left to right: Carr, Gibson and Pogue Skylab program | |
Skylab 4 (also SL-4 and SLM-3[2]) was the third crewed Skylab mission and placed the third and final crew aboard the first American space station.
The mission began on November 16, 1973, with the launch of Gerald P. Carr, Edward Gibson, and William R. Pogue in an Apollo command and service module on a Saturn IB rocket from the Kennedy Space Center, Florida,[3] and lasted 84 days, one hour and 16 minutes. A total of 6,051 astronaut-utilization hours were tallied by the Skylab 4 astronauts performing scientific experiments in the areas of medical activities, solar observations, Earth resources, observation of the Comet Kohoutek and other experiments.
The crewed Skylab missions were officially designated Skylab 2, 3, and 4. Miscommunication about the numbering resulted in the mission emblems reading "Skylab I", "Skylab II", and "Skylab 3" respectively.[2][4]
