The Pressurized Mating Adapter is moved on an air pallet toward Node 1 in KSC's Space Station Processing Facility.

The Pressurized Mating Adapter (PMA)-2, seen here in its yellow workstand, is moved on an air pallet toward Node 1, the International Space Station’s (ISS'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. Node 1 can be seen directly behind PMA-2. 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.
