CAPE CANAVERAL, Fla. - In Orbiter Processing Facility-3 at NASA's Kennedy Space Center in Florida, the orbiter boom sensor system, or OBSS, removed from space shuttle Discovery's payload bay, is lowered onto a transporter. The 50-foot-long OBSS attaches to the end of the shuttle’s robotic arm and supports the cameras and laser systems used to inspect the shuttle’s thermal protection system while in space. The OBSS' inspection boom assembly, or IBA, is removed from the arm every other processing flow for a detailed inspection. After five consecutive flights, all IBA internal components are submitted to a thorough electrical checkout in Kennedy's Remote Manipulator System Lab. Discovery next will deliver the first Permanent Multi-purpose Module, or PMM; the Express Logistics Carrier 4; and critical spare parts to the International Space Station on the STS-133 mission. Launch is targeted for Sept. 16.
