Origination of International Space Station

     The International Space Station is the synthesis  of several space station projects that includes the American Freedom, the Soviet/Russian Mir-2, the European Columbus and the Japanese Kibō that originates during  Cold War. After the failure of the NASA’s freedom, soviet’s Mir-2 as replacement for Mir because of budjeting. At the same time similar budgetary difficulties were faced by other nations with space station projects, which prompted the American government to negotiate with European states, Russia, Japan, and Canada in the early 1990s to begin a collaborative project. As a result  American president George H. W. Bush and Russian president Boris Yeltsin agreed to cooperate on space exploration in 1992. In September 1993, American Vice-President Al Gore Jr, and Russian Prime Minister Viktor Chernomyrdin announced plans for a new space station, which eventually became the International Space Station.The International Space Station program combined the proposed space stations of all participant agencies: NASA's Freedom, the RSA's Mir-2 (with DOS-8 later becoming Zvezda), ESA's Columbus, and the Japanese Kibō laboratory. When the first module, Zarya, was launched in 1998, the station was expected to be completed by 2003. Delays have led to a revised estimated completion date of 2011.
