1989-084A
The fifth flight of Atlantis was another planetary deployment mission. The Galileo space probe with its IUS booster were mounted on an IUS tilt cradle in the payload bay. Special payload bay modifications handled the cooling of the probe's nuclear RTG power system. Galileo was successfully deployed only six hours after launch, in a 295 x 303 km x 34.3 deg orbit. The major secondary payload on this flight was the Solar Backscatter Ultraviolet experiment to measure the ozone concentration in the upper atmosphere; it was carried in GAS cans on the bay sidewall. The STEX and MLE experiments, IMAX camera and plant and polymer experiments were also carried. Atlantis landed at Edwards on Oct 23.
