KENNEDY SPACE CENTER, FLA. -- With umbilical lines still attached, the payload canister containing the Italian-built U.S. Node 2 module, called Harmony, is lifted up toward the payload changeout room on Launch Pad 39A. Once in place, the canister will be opened and the module transferred inside the payload changeout room. The payload will be installed in space shuttle Discovery's payload bay after the vehicle rolls out to the pad. Discovery is targeted for launch to the International Space Station for mission STS-120 on Oct. 23. The pressurized module will act as an internal connecting port and passageway to additional international science labs and cargo spacecraft. Photo credit: NASA/George Shelton
