About ISS:

  • The International Space Station (ISS) is a modular space station (habitable artificial satellite) 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).
  • The ownership and use of the space station is established by intergovernmental treaties and agreements.
  • 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.
  • The ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations and the U.S. Skylab.
  • It is the largest artificial object in space and the largest satellite in low Earth orbit, regularly visible to the naked eye from Earth's surface.
  •  It maintains an orbit with an average altitude of 400 kilometres and circles the Earth in roughly 93 minutes, completing 15.5 orbits per day.
  • The station is divided into two sections: the Russian Orbital Segment (ROS) is operated by Russia, while the United States Orbital Segment (USOS) is run by the United States as well as many other nations.
