KENNEDY SPACE CENTER, Fla. - During suitup, STS-109 Payload Commander John M. Grunsfeld shows his readiness for launch. Liftoff of Space Shuttle Columbia is scheduled for 6:22 a.m. EST March 1. On mission STS-109, the crew will capture the Hubble Space Telescope using the Shuttle's robotic arm and secure it on a workstand in Columbia's payload bay. Four mission specialists will perform five scheduled spacewalks to complete system upgrades to the telescope. More durable solar arrays, a large gyroscopic assembly to help point the telescope properly, a new telescope power control unit, and a cooling system to restore the use of a key infrared camera and spectrometer unit, which has been dormant since 1999, will all be installed. In addition, the telescope's view of the Universe will be improved with the addition of the Advanced Camera for Surveys (ACS), which replaces the Faint Object Camera, the last of Hubble's original instruments. Mission STS-109 is the 27th flight of the orbiter Columbia and the 108th flight overall in NASA's Space Shuttle program. After the 11-day mission, Columbia is scheduled to land about 4:35 a.m. EST March 12
