KENNEDY SPACE CENTER, FLA. - In the Orbiter Processing Facility bay 3, workers install the Orbiter Boom Sensor System (OBSS) onto the starboard side of Discovery’s payload bay. The 50-foot-long OBSS attaches to the Remote Manipulator System, or Shuttle robotic arm, and is one of the new safety measures for Return to Flight, equipping the orbiter with cameras and laser systems to inspect the Shuttle’s Thermal Protection System while in space. The Return to Flight mission, STS-114, has a launch window of May 12 to June 3, 2005.
