NASA News National Aeronautics and Space Administration John F. Kennedy Space Center Kennedy Space Center, Florida 32899 AC 321-867-2468 ____________________________________________________________________________ _______________________________ For Release: Jan. 15, 2003 KSC Contact: Bruce Buckingham (321) 867-2468 KSC Release No. 09 - 03 SHUTTLE MISSION STS-107 LAUNCH TIME ANNOUNCED FOR LAUNCH ON JAN. 16 Managers today confirmed the launch of Space Shuttle Columbia for Thursday, Jan. 16 at 10:39 a.m. EST. The launch window extends for 2 hours and 30 minutes. This announcement comes following a final review of Shuttle processing activities and a satisfactory engineering analysis of the Ball Strut Tie Rod Assembly (BSTRA). STS-107 is a scheduled 16-day mission with a planned KSC landing at about 8:53 a.m. EST on Saturday, Feb. 1. This mission is the first Shuttle mission of 2003. Mission STS-107 is the 28th flight of the orbiter Columbia and the 113th flight overall in NASA's Space Shuttle program. Mission STS-107 is an international mission devoted to space research, the first dedicated research mission to be flown by the Shuttle in almost three years. Columbia will carry in its payload bay the SPACEHAB Research Double Module, a pressurized environment accessible to the crew. The module and the Shuttle's middeck will hold most of the mission's more than 80 experiments - involving more than 70 scientists worldwide - that will investigate space, life and physical sciences. The STS-107 crew includes Commander Rick Husband, Pilot William McCool, Mission Specialists David Brown, Laurel Clark, Kalpana Chawla and Michael Anderson, and Payload Specialist Ilan Ramon with the Israel Space Agency.
