The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).[7][8] The ownership and use of the space station is established by intergovernmental treaties and agreements.[9] The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields.[10][11][12] The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars.
