The International Space Station (ISS) is a space station, or habitable artificial satellite, located in low Earth orbit. It is a collaborative project involving multiple space agencies, including NASA (the United States), Roscosmos (Russia), ESA (the European Space Agency), JAXA (the Japan Aerospace Exploration Agency), and CSA (the Canadian Space Agency). The ISS serves as a microgravity research laboratory where astronauts and cosmonauts from various countries conduct scientific research and experiments in a variety of fields, including biology, physics, astronomy, and Earth science.

NASA, the National Aeronautics and Space Administration, plays a significant role in the operation and maintenance of the International Space Station. NASA's contributions to the ISS program include launching crewed missions to the station, providing transportation for astronauts and cargo using spacecraft like the Space Shuttle and SpaceX's Crew Dragon, and conducting a wide range of experiments and research on the station.

The ISS has been continuously inhabited since the year 2000, and it represents one of the most significant international collaborations in space exploration. It serves as a platform for scientific research and technological advancements while also promoting cooperation among nations in space endeavors.
