KENNEDY SPACE CENTER, FLA. -- At Launch Complex 36-A, Cape Canaveral Air Force Station, a Lockheed Martin Atlas Centaur IIA (AC-144) rocket is lifted up the launch tower. The rocket will be used in the launch of TDRS-J, scheduled for Nov. 20. The third in a series of telemetry satellites, TDRS-J will help replenish the current constellation of geosynchronous TDRS satellites. The TDRS System is the primary source of space-to-ground voice, data and telemetry for the Space Shuttle. It also provides communications with the International Space Station and scientific spacecraft in low-Earth orbit such as the Hubble Space Telescope. This new advanced series of satellites will extend the availability of TDRS communications services until about 2017.

KENNEDY SPACE CENTER, FLA. - From the Payload Changeout Room on Launch Pad 39A, the P1 truss payload, plus the Crew and Equipment Translation Aid (CETA) cart B, are moved into the payload bay of Space Shuttle Endeavour. Scheduled to launch Nov. 10 on mission STS-113, Endeavour will make the 16th assembly flight to the International Space Station. 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. The mission will also deliver the Expedition 6 crew to the Station and return Expedition 5 to Earth.
