The Galileo spacecraft and its Inertial Upper Stage (IUS) booster were deployed from the cargo bay of STS-34 Atlantis. Deployment occurred at 7:15 P.M. EDT on October 18, 1989. Beginning an hour after deployment, two rocket stages of the IUS fired in succession. Galileo separated from the IUS' second stage at 9:05 P.M. and began its ballistic flight to Venus for the first of three gravity-assisted flybys, which will take Galileo to Jupiter.
The Jet Propulsion Laboratory, Pasadena, CA manages the mission for NASA's Office of Space Science, Washington, DC.
