About ISS
The International Space Station is the largest human-made structure in space, orbiting Earth approximately every 92 minutes at an altitude of around 408 km. It serves as a microgravity research laboratory where crew members conduct experiments in biology, physics, astronomy, and materials science. The ISS has been continuously occupied since November 2000 and is a joint project among five space agencies. It travels at roughly 7.66 km/s, completing about 16 orbits per day, and is often visible to the naked eye from the ground.
