The crew is preparing for the mission aboard Space Shuttle Endeavour, which is scheduled to launch Nov. 10, by taking part in Terminal Countdown Demonstration Test activities. The TCDT includes a simulated launch countdown.. The primary payloads on mission STS-113 are the first port truss segment, P1, and the Crew and Equipment Translation Aid (CETA) Cart B. Once delivered, the P1 truss will remain stowed until flight 12A.1 in 2003 when it will be attached to the central truss segment, S0, on the Space Station. Also onboard Space Shuttle Endeavour will be the Expedition 6 crew who will replace Expedition 5, returning to Earth after 4 months.
