Space Shuttle Projects

The sun rises on the Space Shuttle Discovery as it rests on the runway at Edward’s Air Force Base in California after a safe landing at 5:11 am (PDT) on August 9, 2005. The STS-114 landing concluded a historic 14 day return to flight mission to the International Space Station (ISS) after nearly a two and one half year delay in flight after the Space Shuttle Columbia tragedy in February 2003. Three successful space walks performed during the mission included a demonstration of repair techniques to the Shuttle’s thermal tiles known as the Thermal Protection System, the replacement of a failed Control Moment Gyroscope which helps keep the station oriented properly, and the installation of the External Stowage Platform, a space “shelf” for holding spare parts during Station construction. The shuttle’s heat shield repair was a first for Shuttle repair while still in space.
