In Orbiter Processing Facility bay 1 at NASA's Kennedy Space Center, workers complete installation of the orbiter boom sensor system into Atlantis' payload bay. The 50-foot-long boom attaches to the shuttle arm and is one of the new safety measures added prior to Return to Flight last year. It equips the orbiter with cameras and laser systems to inspect the shuttle's heat shield while in space. Atlantis is scheduled to launch on mission STS-115 no earlier than Aug. 28.
