STS-113 Mission Commander James Wetherbee practices driving an M-113 armored personnel carrier, part of emergency egress training during Terminal Countdown Demonstration Test activities. He and the rest of the crew are preparing for the mission aboard Space Shuttle Endeavour, which is scheduled to launch Nov. 10. The TCDT includes a 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.
