Suspended by an overhead crane in the Space Station Processing Facility, the International Space Station’s P4 truss moves toward a workstand. Below and behind it on the floor is the Multi-Purpose Logistics Module Raffaello, another segment of the Space Station. Part of the 10-truss, girder-like structure that will ultimately extend the length of a football field, the P4 is the second port truss segment that will attach to the first port truss segment (P1 truss). The P4 is scheduled for mission 12A in September 2002.
