Missions to the Stars
The International Space Station (ISS) is a modular space station 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 ISS serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. It is the largest artificial object in space and the largest satellite in low Earth orbit.
The station is divided into two sections: the Russian Orbital Segment (ROS), which is operated by Russia, and the United States Orbital Segment (USOS), which is shared by many nations. The ISS has been continuously occupied for over 20 years, supporting a long-term human presence in space.
