Design features of the Centaur upper stage for the Shuttle are described, noting interfaces with the Orbiter and intended missions. The Shuttle will carry the Centaur stage into a 241 km eastward orbit, open the payload doors, and by the fourth orbit rotate the Centaur 45 deg so it points out of the bay. An integrated support system will limit the actual equipment added to the Orbiter to 122 kg. Separation from the Orbiter will be effected by a spring-loaded mechanism that will impart a 1/3 m/sec velocity to the Centaur, which carries its own LOX/LH2 fuel supply for two RL 10A-3-3A engines. The fuel is moved to the bottom of the tanks by auxiliary thrusters which propel the Centaur forward. Planned missions for the Shuttle-Centaur are boosting the ESA Solar Polar Mission and launching the Galileo probe in 1986, possibly followed by a Venus radar mapper mission in 1988.
