Who put together the international space station?

The International Space Station (ISS) is a collaborative project involving multiple space agencies, primarily NASA (United States), Roscosmos (Russia), ESA (European Space Agency), JAXA (Japan), and CSA (Canadian Space Agency). Construction began in 1998, with the first module, Zarya, launched by Russia. Since then, numerous modules and components have been added through various missions, resulting in the ISS as a symbol of international cooperation in space exploration.
