(02/17/1998) --- The Pressurized Mating Adapter (PMA)-2 for the International Space Station (ISS), seen here in its yellow workstand, is moved on an air pallet toward Node 1, the space station’s structural building block, in KSC’s Space Station Processing Facility. This PMA is a cone-shaped connector to Node 1, which will have two PMAs attached once PMA-2 is mated with the node. The node and PMAs, which together will make up the first element of the ISS, are scheduled to be launched aboard the Space Shuttle Endeavour on STS-88
