European contribution to the International Space Station : ウィキペディア英語版 | European contribution to the International Space Station The European contribution to the International Space Station comes from 10 members of the European Space Agency (ESA) and amounts to an 8% share in the programme. It consists of a number of modules (primarily the Columbus laboratory) in the US segment, ATV supply ships, launchers, software and €8 billion. ==History==
In the 1980s, ESA devised plans for its own space station called Columbus which could be attached to NASA's Space Station Freedom. America objected to ESA's using Columbus as building block of a future European space station, and were concerned that they would facilitate the creation of a potential competitor if the manned space outpost fulfilled its promise as supplier of commercially viable products, such as new materials and pharmaceuticals. Plans were scaled down as a result, and by 1988, Europe proposed to participate with three elements: Attached Pressurized Module, Man Tended Free-Flying platform, plus an unmanned polar remote sensing platform. This would be supported by the Ariane 5 rocket and the Hermes spaceplane (a mini space shuttle). However, after German reunification, ESA's budget reductions meant something had to be cancelled.〔(【引用サイトリンク】title=ESA Polar Platform )〕〔(【引用サイトリンク】title=Columbus space station module )〕 The collapse of the Soviet Union and the Space Shuttle Challenger disaster meant a radical change in plans for a space station. The US and Russia decided to cooperate on an International Space Station. ESA cancelled much of its space station programme to focus on the Columbus module, reconfigured for the ISS.〔 The module was approved in 1995 but delays in station construction meant Columbus would not fly until 2008.〔(From Spacelab to Columbus ), ESA〕
