The International Space Station (ISS) is a massive research laboratory orbiting Earth. Built by multiple space agencies, it serves as a hub for scientific studies, testing new technologies, and preparing for deep-space missions. Astronauts from around the world live and work aboard the ISS.
The station orbits Earth at 28,000 km/h, completing a full trip every 90 minutes. It provides valuable insights into space travel, microgravity effects, and the potential for future Mars missions. The ISS remains one of humanity’s greatest engineering achievements.
