Historical Notes: This star chart was used by astronauts Charles Conrad Jr., Paul Weitz and Joseph P. Kerwin on their return, inside a Command/Service Module, from the Skylab space station. Skylab was launched on May 14, 1973, from Kennedy Space Center in Florida. The first manned mission to the station, Skylab 2, was launched on a Saturn 1B rocket on May 25, 1973. The three man crew was responsible for the repair of the station’s Sun and meteorite shield and solar array, both of which had been damaged during launch. In addition to repairs, the crew was responsible for performing scientific experiments, at least one of which confirmed the existence of holes in the Sun’s corona. In total, the Skylab 2 mission lasted 28 days, and was the first successful return to Earth of astronauts from a space station.
