Astronaut Scholarship Foundation guests at the Kennedy Space Center's Apollo/Saturn V Center listen as Skylab era astronauts celebrate the 40th anniversary of Skylab.

The gala commemorating the 40th anniversary of Skylab included six of the nine astronauts who flew missions to America's first space station. The orbiting laboratory was launched unpiloted from Kennedy on May 14, 1973. Between May 25, 1973 and Feb. 8, 1974, crews of three spent 28, 59 and 84 days living and working in low-Earth orbit aboard the station.
