New Girder Bolted to Station

Atlantis

astronauts Jerry Ross and Lee Morin completed a seven hour spacewalk on Saturday to finish bolting the newly installed S0 truss to the International Space Station. Dubbed the Silver Team because of their age (both are grandfathers), the two astronauts found some of the 54 bolts they tightened were a little sticky. The truss will hold the station's giant solar wings and serve as a track for the Canadarm 2 to travel across the station.
