12/09/2006 - Space Shuttle Discovery seems to be standing on the fiery columns erupting from the solid rocket boosters as it lifts off Launch Pad 39B on mission STS-116. Liftoff occurred on time at 8:47 p.m. EST. This was the second launch attempt of Discovery on mission STS-116. The first launch attempt on Dec. 7 was postponed due a low cloud ceiling over Kennedy Space Center. This is Discovery's 33rd mission and the first night launch since 2003. 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.
