Media representatives await the arrival of the STS-116 crew at the Shuttle Landing Facility. On this mission, the crew will deliver another truss segment, P5, to the International Space Station and begin the intricate process of reconfiguring and redistributing the power generated by two pairs of U.S. solar arrays. The P5 will be mated to the P4 truss that was delivered and attached during the STS-115 mission in September. Launch of Discovery is scheduled for 9:35 p.m. Dec. 7. Photo credit: NASA/Kim Shiflett
