Manufacturing of the International Space Station

The project began as Space Station Freedom, a US only effort, but was long delayed by funding and technical problems. Following the initial 1980's authorization (with an intended ten year construction period) by Ronald Reagan, the Station Freedom concept was designed and renamed in the 1990s to reduce costs and expand international involvement. In 1993, the United States and Russia agreed to merge their separate space station plans into a single facility integrating their respective modules and incorporating contributions from the European Space Agency and Japan.[3] In later months, an international agreement board recruited several more space agencies and companies to collaborate to the project. The International Organization for Standardization played a crucial role in unifying and overcoming different engineering methods (such as measurements and units), languages, standards and techniques to ensure quality, engineering communication and logistical management across all manufacturing activities of the station components.

Once manufactured or fabricated sufficiently, most of the space station elements were transported by aircraft (usually the Airbus Beluga or the Antonov An-124) to the Kennedy Space Center Space Station Processing Facility for final manufacturing stages, checks and launch processing. Some elements arrived by ship at Port Canaveral.[23][24]

Each module for aircraft transport was safely housed in a custom-designed shipping container with foam insulation and an outer shell of sheet metal, to protect it from damage and the elements. At their respective European, Russian and Japanese factories, the modules were transported to their nearest airport by road in their containers, loaded into the cargo aircraft and were flown to Kennedy Space Center's Shuttle Landing Facility for unloading and final transfers to the SSPF and or the Operations and Checkout Building in the KSC industrial area. The American and Canadian-built components such as the US lab, Node 1, Quest airlock, truss and solar array segments, and the Canadarm-2 were either flown by the Aero Spacelines Super Guppy to KSC, or transported by road and rail.[25]

After final stages of manufacturing, systems testing and launch checkout, all ISS components are loaded into a payload transfer container in the shape of the Space Shuttle payload bay. This container safely carries the component in its launch configuration until it is hoisted vertically at the launch pad gantry for transfer to the Space Shuttle orbiter for launch and in-orbit assembly of the International Space Station.[26]
