Deployment from the Shuttle

The Galileo spacecraft and its Inertial Upper Stage booster rocket were deployed from the space shuttle Atlantis October 18, 1989. Shortly thereafter, the booster rocket fired and separated, sending Galileo on its six-year journey to the planet Jupiter. Upon its arrival at Jupiter in December 1995, Galileo released a probe into the atmosphere so that scientists could survey the composition of the planet's clouds. The orbiter has relayed probe information, surveyed its surroundings, and photographed Jupiter and some of its major satellites.

Getting Ready for Launch

This photo shows the Galileo spacecraft being prepared for mating to its Inertial Upper Stage. The black and gold fabric that covers the spacecraft is designed to protect it from both the heat of the sun and the chill of interplanetary space. The conical structure near the bottom of the spacecraft conceals the atmospheric probe, which dropped into the Jovian atmosphere on December 7, 1995.
