NASA Kennedy Space Center Space Patch - Mission STS-114 - Signed by Astronaut

Signed by astronaut Wendy Lawrence at NASA's Kennedy Space Center Visitor Complex "STS-114 Design No. 111371 Discovery's seven-member Return to Flight crew will fly to the International Space Station primarily to test and evaluate new safety procedures. There have been many safety improvements to the Shuttle, including a redesigned External Tank, new sensors and a boom that will allow astronauts to inspect the Shuttle for any potential damage. Two crewmembers, Steve Robinson and Soichi Noguchi, will venture outside the Shuttle three times on spacewalks. The first will demonstrate repair techniques on the Shuttle's protective tiles, known as the Thermal Protection System. During the second spacewalk, they'll replace a failed Control Moment Gyroscope, which helps keep the station oriented properly. Finally, they'll install the External Stowage Platform, a sort of space shelf for holding spare parts during Station construction."
