Crew notes[edit]

John M. Fabian was scheduled to fly as Mission Specialist 1 on his third trip to space, but due to concerns and stress about the Centaur-G worst-case-scenarios, he resigned from this mission.[1] His replacement was Norman E. Thagard.[2] Most of the crew sans van Hoften flew on STS-30 in May 1989, with Mary Cleave taking the place of van Hoften and the addition of rookie Mark Lee. Galileo was launched on STS-34 in October 1989, using the Inertial Upper Stage booster instead of the Centaur-G (which was canceled in 1986).
