The International Space Station (ISS) is an international research facility mounted on a low-altitude orbit 2,000 km above the Earth’s surface. It can be seen with the naked eye.
The current space station is longer than its predecessors and is a satellite that orbits the Earth and is visible to the naked eye.
Scientists have used the International Space Station as a microgravity laboratory for extremely low gravity, and for biological, Biology Chemistry Physical, and medical experiments are performed. They observe space and weather.
