The main purpose of the International Space Station (ISS) is to serve as a research laboratory and observatory, enabling scientific experiments in a microgravity environment. It facilitates research in various fields, such as biology, physics, astronomy, and materials science, that would be impossible or difficult to conduct on Earth. The ISS also provides valuable insights into human health and behavior in space, which are crucial for future long-duration space missions. In addition to its scientific mission, the ISS fosters international cooperation in space exploration, with contributions from space agencies like NASA, Roscosmos, ESA, JAXA, and CSA.
