The Nile River is seen during the third spacewalk, Aug. 3, 2005. Mission Specialist Steve Robinson's shadow is also visible.
Robinson made unprecedented repairs during the spacewalk, going beneath Discovery's belly to remove two protruding strips of tile filler that engineers thought could lead to dangerous overheating during the trip home.

President Bush, left, smiles after finishing a conversation with the space shuttle Discovery and international space station crews, seen on screen, in the Roosevelt Room of the White House, Aug. 2, 2005. President Bush phoned Discovery's astronauts, thanking them for being "risk takers for the sake of exploration."

Astronaut Soichi Noguchi waves from the shuttle payload bay, backdropped by the Earth below, Aug. 1, 2005. During the mission's second spacewalk, Noguchi and Discovery crewmate Steve Robinson replaced a failed gyroscope, which keeps the International Space Station in the proper position in orbit.

Astronauts Steve Robinson, left, and Soichi Noguchi prepare for the first of three spacewalks, July 30, 2005.
They restored power to a gyroscope on the international space station. Only two of the four gyroscopes that control the orientation of the orbiting science lab have worked recently. NASA hoped to have all four gyroscopes operating simultaneously for the first time in three years.

Space shuttle Discovery performs a unprecedented backflip to allow the international space station to take detailed photos of the craft's heat shield, July 28, 2005.
All the photography and laser imaging being aimed at normally hard-to-see spots on the craft revealed a couple of short strips of fabric dangling from the craft's underside.

Members of the space shuttle Discovery crew are seen on board the international space station, July 28, 2005. The astronauts were greeted with hugs and bread and salt - a Russian tradition thought to bring good luck when visiting another's home -- when they entered the orbital lab.

The docking came after a huge setback, in which NASA decided to ground future shuttle flights because a chunk of insulating foam flew off Discovery's fuel tank during liftoff -- as it did in Columbia's doomed mission. This time, the foam apparently missed the spacecraft. The area of missing foam is indicated by a light spot near the upper edge of the tank in this photo, which was taken after the launch, July 26, 2005.
