The ISS is a joint project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits Earth at an average altitude of approximately 400 km and travels at a speed of 28,000 km/h, completing an orbit every 90 minutes. The station has hosted astronauts from 19 different countries and has been instrumental in advancing understanding of microgravity’s effects on the human body, material science, and biological research.
