Space Shuttle Discovery stands ready for launch on mission STS-103 as rain falls all around it.

In the early morning at Launch Complex 39B, Space Shuttle Discovery stands ready for launch on mission STS-103 as rain falls all around it. Uncooperative weather also caused the scrub of a launch attempt Friday evening at about 8:52 p.m. EST. The STS-103 mission, to service the Hubble Space Telescope, is now scheduled for launch on Dec. 18 at 8:21 p.m. EST. Mission objectives include replacing gyroscopes and an old computer, installing a backup solid state recorder, and replacing damaged insulation on the telescope
