The vehicle processing team has a final goodbye and gathers for a photo in front of space shuttle Discovery after its exit from the Orbiter Processing Facility bay 3. The vehicle is rolling over to the Vehicle Assembly Building, where it will be lifted and mated with the external tank and solid rocket boosters on the mobile launcher platform. Discovery is targeted for launch to the International Space Station for mission STS-120 on Oct. 23. The crew will be delivering and installing the Italian-built U.S. Node 2, named Harmony. The pressurized module will act as an internal connecting port and passageway to additional international science labs and cargo spacecraft. In addition to increasing the living and working space inside the station, it also will serve as a work platform outside for the station's robotic arm. Photo credit: NASA/Charisse Nahser
