First manned mission. 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 totaled six hours, 20 minutes.
