Crew Completes Late Inspection

Space shuttle Atlantis’ crew completed today’s inspection of the shuttle’s thermal protection system at 10:30 a.m. EDT. They used the 50-foot long Orbiter Boom Sensor System to conduct a high fidelity, three-dimensional scan of areas of the shuttle that experience the highest heating during entry—the wing leading edges and nose cap. Managers and engineers in Mission Control will review the data today and tomorrow to validate the heat shield’s integrity.

This marks the final use of the shuttle’s robotic arm, dating back to its inaugural flight on the shuttle Columbia in October 1981on the STS-2 mission, operated by Commander Richard Truly and Pilot Joe Engle for approximately 10 hours of checkout operations. Canadarm deployed and retrieved its first payload, the Plasma Diagnostic Package, on Columbia’s STS-3 mission of Commander Jack Lousma and Pilot Gordon Fullerton.
