KENNEDY SPACE CENTER, FLA. -- Boeing technicians move a piece of hardware into position on Node 1 of the International Space Station (ISS) in KSC's Space Station Processing Facility in preparation for mating with Pressurized Mating Adapter (PMA)-2. The node is the first element of the ISS to be manufactured in the United States and is currently scheduled to lift off aboard the Space Shuttle Endeavour on STS-88 later this year, along with PMAs 1 and 2. The 18-foot-in-diameter, 22-foot-long aluminum module was manufactured by the Boeing Co. at Marshall Space Flight Center. Once in space, Node 1 will function as a connecting passageway to the living and working areas of the ISS. It has six hatches that will serve as docking ports to the U.S. laboratory module, U.S. habitation module, an airlock and other space station elements
