The P-1 truss (top of photo), a component of the International Space Station, nears its work stand in the Operations and Checkout Building where it will undergo processing. Scheduled to fly in spring of 2002, the P-1 is part of a total 10-truss, girder-like structure on the Station that will ultimately extend the length of a football field. Astronauts will attach the 14-by-15 foot structure to the port side of the center truss, S0, during the spring assembly flight. The 33,000-pound P-1 will house the thermal radiator rotating joint (TRRJ) that will rotate the Station’s radiators away from the sun to increase their maximum cooling efficiency
