File Description:
Skylab 2 25 May 1973 13:00 GMT. Duration: 28.03 days. Call Sign: Skylab. Backup Crew: McCandless, Musgrave, Schweickart. Nation: USA. Agency: NASA. Launch Site: Cape Canaveral . Launch Complex: LC39B. Launch Vehicle: Saturn IB . LV Configuration: Saturn IB s/n SA-206. Program: Skylab. Class: Manned. Type: Lunar spacecraft. Spacecraft: Apollo CSM. Payload : Apollo CSM 116. Mass: 19,979 kg. Location of Spacecraft: Naval Aviation Museum, Pensacola, FL. Perigee: 427 km. Apogee: 439 km. Inclination: 50.0 deg. Period: 93.2 min. Epic repair mission which brought Skylab into working order. Included such great moments as Conrad being flung through space by the whiplash after heaving on the solar wing just as the debris constraining it gave way; deployment of a lightweight solar shield, developed in Houston in one week, which brought the temperatures down to tolerable levels. With this flight US again took manned spaceflight duration record. When the meteoroid shield ripped loose, it disturbed the mounting of workshop solar array "wing" two and caused it to partially deploy. The exhaust plume of the second stage retro-rockets impacted the partially deployed solar array and literally blew it into space. Also, a strap of debris from the meteoroid shield overlapped solar array "wing" number one such that when the programmed deployment signal occurred, wing number one was held in a slightly opened position where it was able to generate virtually no power. In the meantime, the space station had achieved a near-circular orbit at the desired altitude of 435 kilometers (270 miles). All other major functions including payload shroud jettison, deployment of the Apollo Telescope Mount (Skylab's solar observatory) and its solar arrays, and pressurization of the space station occurred as planned. Scientists, engineers, astronauts, and management personnel at the NASA Marshall Space Flight Center and elsewhere worked throughout the first ten-day period of Skylab's flight to devise the means for its rescue. Simultaneously, Skylab--seriously overheating--was maneuvered through varying nose-up attitudes that would best maintain an acceptable "holding" condition. Because of the loss of the meteoroid shield, however, this positioning caused workshop temperatures to rise to 52 degrees Celsius (126 degrees F). During that ten-day period and for some time thereafter, the space station operated on less than half of its designed electrical system, in the partially nose-up attitudes, was generating power at reduced efficiency. The optimum condition that maintained the most favorable balance between Skylab temperatures and its power generation capability occurred at approximately 50 degrees nose-up. The crew rendezvoused with Skylab on the fifth orbit. After making substantial repairs, including deployment of a parasol sunshade which cooled the inside temperatures to 23.8 degrees C (75 degrees F), by June 4 the workshop was in full operation. In orbit the crew conducted solar astronomy and Earth resources experiments, medical studies, and five student experiments; 404 orbits and 392 experiment hours were completed; three EVAs totalled six hours, 20 minutes. Skylab 3 28 July 1973 11:10 GMT. Duration: 59.46 days. Call Sign: Skylab. Backup Crew: Brand, Lenoir, Lind. Nation: USA. Agency: NASA. Launch Site: Cape Canaveral . Launch Complex: LC39B. Launch Vehicle: Saturn IB . LV Configuration: Saturn IB s/n SA-207. Program: Skylab. Class: Manned. Type: Lunar spacecraft. Spacecraft: Apollo CSM. Payload: Apollo CSM 117. Mass: 20,121 kg. Location of Spacecraft: NASA Lewis Research Center, Cleveland, OH. Perigee: 422 km. Apogee: 442 km. Inclination: 50.0 deg. Period: 93.2 min. 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. Skylab4 16 November 1973 14:01 GMT. Duration: 84.05 days. Call Sign: Skylab. Backup Crew: Brand, Lenoir, Lind. Nation: USA. Agency: NASA. Launch Site: Cape Canaveral . Launch Complex: LC39B. Launch Vehicle: Saturn IB . LV Configuration: Saturn IB s/n SA-208. Program: Skylab. Class: Manned. Type: Lunar spacecraft. Spacecraft: Apollo CSM. Payload: Apollo CSM 118. Mass: 20,847 kg. Location of Spacecraft: National Air and Space Museum (Smithsonian Institution), Washington, DC. Perigee: 422 km. Apogee: 437 km. Inclination: 50.0 deg. Period: 93.1 min. Included observation and photography of Comet Kohoutek among numerous experiments. Completed 1,214 Earth orbits and four EVAs totalling 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.
