Node 1, the first U.S. element for the International Space Station, and Pressurized Mating Adapter-1 (PMA-1) continue with prelaunch preparation activities at KSC's Space Station Processing Facility. The node and PMA-1 are seen here on a workstand getting ready to be moved the next day to a weight and balance stand for an interim weight and center of gravity determination. (The final determination is planned to be performed prior to transporting Node 1 to the launch pad.) Upon completing the interim determination, the node and PMA will be hoisted into the Shuttle payload transportation canister and the doors will be closed for a two-week leak check. Node 1 is a connecting passageway to the living and working areas of the space station. Node 1 is scheduled to fly on STS-88.
