Inside the Operations and Checkout Building, the S1 truss, a segment of the International Space Station, is lowered toward workstand number three. Manufactured by the Boeing Co. in Huntington Beach, Calif., this component of the International Space Station 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. Primarily constructed of aluminum, the truss segment is 45 feet long, 15 feet wide and 6 feet tall. When fully outfitted, it will weigh 31,137 pounds. The truss is slated for flight in 2001
