The STS-114 mission delivered supplies to the International Space Station. However, the major focus of the mission was testing and evaluating new Space Shuttle flight safety techniques, which included new inspection and repair techniques. The crew conducted three spacewalks while at the station. The first demonstrated repair techniques on the Shuttle's Thermal Protection System. During the second, the spacewalkers replaced the failed gyroscope. On the third, they installed the External Stowage Platform and repaired the shuttle, the first time repairs had been carried out during a spacewalk on the exterior of a spacecraft in flight. The flight provided unprecedented information on the condition of an orbiter in space. Noguchi and Robinson did three successful spacewalks at the International Space Station and Discovery transported tons of equipment and supplies to and from the Station. Viewers get to experience all of the action first hand spend each day on board with the crew.
