Space Shuttle Discovery astronauts Soichi Noguchi of JAXA and Stephen K. Robinson of NASA performed the second of three scheduled spacewalks for STS-114. The two astronauts conducted tests on materials designed to service the orbiter's heat-shielding tiles and replaced a 600-pound (272.2-kilogram) gyroscope on the exterior of the ISS. The device was one of four gyroscopes that help maintain the station's orientation in space.
