KENNEDY SPACE CENTER, FLA. -- STS-113 Commander James Wetherbee arrives at KSC's Shuttle Landing Facility to get ready for launch. STS-113 is the 16th American assembly flight to the International Space Station. The primary objective of the mission is bringing the Expedition 6 crew to the Station and returning the Expedition 5 crew to Earth. The major task of the mission is delivery of the Port 1 (P1) Integrated Truss Assembly, which will be attached to the port side of the S0 truss. Three spacewalks are planned to install and activate the truss and its associated equipment. Launch of Space Shuttle Endeavour on mission STS-113 is targeted for no earlier than Nov. 22 between 7 and 11 p.m. EST.
