The space shuttle Atlantis undocked from the International Space Station Wednesday afternoon after completing its mission to install a truss on the orbiting facility. Atlantis undocked from the station at 2:31 pm EDT (1831 GMT), a week after arriving at the station. During its stay at the station the crew of STS-110 added to the station the S0 truss segment, the first portion of the station's backbone, completing the installation during a series of four spacewalks. Atlantis is scheduled to land back at the Kennedy Space Center, Florida at 12:37 pm EDT (1637 GMT) to conclude its 11-day mission.
