KENNEDY SPACE CENTER, FLA. -- At Launch Pad 39B, the payload canister for Space Shuttle Discovery, for mission STS-103, is lifted up the Rotating Service Structure. Installation of the payload into Discovery is slated for Friday, Nov. 12. The mission is a "call-up" due to the need to replace portions of the pointing system, the gyros, which have begun to fail on the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will also be replacing a Fine Guidance Sensor and an older computer with a ne — NASA KSC · 1999.
