CAPE CANAVERAL, Fla. – In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, workers take measurements of the Cupola module being aligned with the Tranquility module for assembly. Cupola and Tranquility are the payload for space shuttle Endeavour's STS-130 mission to the International Space Station. The module was built for the European Space Agency by Alenia Spazio in Turin, Italy. When attached to the Tranquility Node 3 module, Cupola will resemble a circular bay window that will provide a vastly improved view of the station's exterior. Just under 10 feet in diameter, the module will accommodate two crew members and portable workstations that can control station and robotic activities. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects.

KENNEDY SPACE CENTER, FLA. -- The International Space Station's (ISS) Unity node, with Pressurized Mating Adapter (PMA)-2 attached, awaits further processing in the Space Station Processing Facility (SSPF). The Unity 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. Unity has two PMAs attached to it now that this mate is completed. PMAs are conical docking adapters which will allow the docking systems used by the Space Shuttle and by Russian modules to attach to the node's hatches and berthing mechanisms. Once in orbit, Unity, which has six hatches, will be mated with the already orbiting Control Module and will eventually provide attachment points for the U.S. laboratory module; Node 3; an early exterior framework or truss for the station; an airlock; and a multi-windowed cupola. The Control Module, or Functional Cargo Block, is a U.S.-funded and Russian-built component that will be launched aboard a Russian rocket from Kazakstan
