STS115-S-034 (9 Sept. 2006) --- The Space Shuttle Atlantis and its six-member crew launch at 11:15 a.m. (EDT) to begin the two-day journey to the International Space Station on the STS-115 mission. Atlantis is slated to dock with the station on Monday Sept. 11, 2006. During the 11-day mission, the STS-115 crew of six will resume construction of the station. The shuttle and station crews will work with ground teams to install a girder-like structure, known as the P3/P4 truss aboard the station. The 35,000-pound piece includes a set of giant solar arrays, batteries and associated electronics. The arrays eventually will double the station's power capability.
