International Space Station IS

The International Space Station (ISS) is a modular space station (habitable artificial satellite) in low Earth orbit. The ISS program is a multi-national collaborative project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).

It is an international collaborative effort between multiple countries. The ownership and use of the space station is established by intergovernmental treaties and agreements. It evolved from the Space Station Freedom proposal.
