July 26, 2010 - Return to Flight

Return to Flight Following the loss of the shuttle Columbia in February 2003, the space shuttle fleet was grounded for more than two-and-a-half years while new procedures and tools were developed to prevent a similar accident. When Discovery lifted off on the STS-114 mission five years ago this week, ground cameras and onboard cameras watched for any insulating foam that could have damaged the orbiter during ascent. Discovery executed a graceful backflip maneuver—now standard—when it reached the International Space Station, allowing further examination of its surfaces by the ISS crew. Finally, the new Orbiter Boom Sensor allowed remote inspection of Discovery’s thermal protection system. Spacewalking astronauts also tested new techniques for repairing damaged tiles in flight.
