The International Space Station is a modular space station in low Earth orbit.

It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA.

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 circles the Earth in roughly 93 minutes, completing 15.5 orbits per day.
