A fish-eye view curves the fixed service structure toward Space Shuttle Atlantis as it hurtles past, propelled by columns of fire from the solid rocket boosters. Below, the smoke and steam billows across Launch Pad 39B. At the lower left is the White Room that, when extended against Atlantis, gave the mission crew access to the orbiter. Atlantis is heading for a rendezvous with the International Space Station on mission STS-115. Liftoff was on-time at 11:14:55 a.m. EDT. After several launch attempts were scrubbed due to weather and technical concerns, this launch was executed perfectly. Mission STS-115 is the 116th space shuttle flight, the 27th flight for orbiter Atlantis, and the 19th U.S. flight to the International Space Station. During the mission, Atlantis' astronauts will deliver and install the 17.5-ton, bus-sized P3/P4 integrated truss segment on the station. The girder-like truss includes a set of giant solar arrays, batteries and associated electronics and will provide one-fourth of the total power-generation capability for the completed station. STS-115 is scheduled to last 11 days with a planned landing at KSC
