KSC-2009-1191

CAPE CANAVERAL, Fla. – In the Payload Changeout Room on Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers check the progress of the payload for the STS-119 mission as it is transferred to space shuttle Discovery's cargo bay (bottom of photo). The payload consists of the integrated truss structure S6 and solar arrays. During Discovery's 14-day mission, the shuttle's seven astronauts will install the S6 truss segment and solar arrays to the starboard side of the International Space Station, completing the station's truss, or backbone. Launch of Discovery on the STS-119 mission is targeted for Feb. 12. Photo credit: NASA/Kim Shiflett
