CAPE CANAVERAL, Fla. – In the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, the external fuel tank for space shuttle Atlantis' STS-125 mission is raised from the checkout cell in order to move it to high bay 3. There it will be lowered onto the mobile launcher platform and attached to the solid rocket boosters already installed. Atlantis' STS-125 mission is the fifth and final shuttle servicing mission to NASA’s Hubble Space Telescope. Launch is targeted for May 12. Photo credit: NASA/Jack Pfaller

CAPE CANAVERAL, Fla. – In the Payload Changeout Room on Launch Pad 39A at NASA's Kennedy Space Center in Florida, the payload for the STS-119 mission is being transferred to space shuttle Discovery's cargo bay. 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
