KENNEDY SPACE CENTER, FLA. - In the back transfer aisle of the Orbiter Processing Facility bay 3, a worker checks the resistance measurement of one of the Thermal Protection System (TPS) blanket ground wires to ensure a proper ground between the blanket to be installed and the Orbiter Boom Sensor System (OBSS). The installation will conclude TPS closeout prior to installation of the boom in the orbiter Discovery. The OBSS is one of the new safety measures for Return to Flight, equipping the Shuttle with cameras and laser systems to inspect the Shuttle’s Thermal Protection System while in space
