KENNEDY SPACE CENTER, FLA. -- As part of the Crew Equipment Interface Test, members of the STS-112 crew look at the S1 Integrated Truss Structure, part of the payload for their mission to the International Space Station. From left are Pilot Pamela Melroy and Mission Specialists Piers Sellers and Sandra Magnus. At right, looking up, is Commander Jeffrey Ashby. The S1 truss is the first starboard (right-side) truss segment, whose main job is providing structural support for the orbiting research facility's radiator panels that cool the Space Station's complex power system. The S1 truss segment also will house communications systems, external experiment positions and other subsystems. The S1 truss will be attached to the S0 truss. Launch of STS-112 is scheduled for Aug. 22, 2002 KSC-02pd0990
