The International Space Station (ISS) is a large spacecraft and space laboratory that orbits Earth. It serves as a microgravity research laboratory where scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is a joint project involving space agencies from multiple countries, including NASA (United States), Roscosmos (Russia), ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), and CSA (Canadian Space Agency). It orbits the Earth at an average altitude of approximately 400 kilometers (about 250 miles) and travels at a speed of about 28,000 kilometers per hour (about 17,500 miles per hour). The ISS hosts a rotating crew of astronauts and cosmonauts who live and work on board for extended periods, typically conducting experiments and maintaining the station’s systems.
