STS-103 - - 1999 Dec 20 - Assignment: Prime Crew. Flight Time: 7.97 days. Flight details: STS-103.
Hubble Space Telescope (HST) servicing mission SM-3A, delayed repeatedly by technical problems with the shuttle fleet after the near-disastrous previous launch. Finally launched after the last possible day to avoid Y2K computer problems; one spacewalk was cancelled so that the shuttle could return by December 28. Hubble was in a 591 km x 610 km x 28.5 deg orbit at launch. After separation of the external tank ET-101 the Orbiter was in a 56 km x 587 km x 28.5 deg transfer orbit. The OMS 2 burn at 0134 UTC raised the orbit to 313 km x 582 km. The payload bay contained:
Hubble was grabbed by the shuttle's robot arm at 0034 UTC on December 22. Following completion of repairs HST was released on December 25 at 2303 UTC. The deorbit burn at 2248 UTC on Dec 27 placed the orbiter in a 50 km x 616 km descent orbit. Discovery landed on runway 33 at Kennedy Space Center at 0001 UTC on December 28.
