On the morning of the second launch attempt Space Shuttle Discovery is ready on Launch Pad 39B.

On the morning of the second launch attempt, Space Shuttle Discovery is ready on Launch Pad 39B. It is still surrounded by the rotating service structure, hiding all but the top of the external tank. On the left side is the fixed service structure, topped by the 80-foot-tall lightning mast. The first launch attempt of STS-116 Dec. 7 was postponed due a low cloud ceiling over Kennedy Space Center. The next launch attempt was scheduled for Saturday, Dec. 9, at 8:47 p.m. This will be Discovery's 33rd mission and the first night launch since 2002. The 20th shuttle mission to the International Space Station, STS-116 carries another truss segment, P5. It will serve as a spacer, mated to the P4 truss that was attached in September. After installing the P5, the crew will reconfigure and redistribute the power generated by two pairs of U.S. solar arrays. Landing is expected Dec. 19 at KSC. Photo credit: NASA/Ken Thornsley
