The Mir system is a Russian space station that was operational from 1986 to 2001. It was one of the largest human-made structures in space and served as a platform for scientific research and international cooperation. The station was modular, allowing for various components to be added over time, which enhanced its capabilities. During its 15 years in orbit, the Mir system hosted numerous astronauts from different countries, contributing to advancements in space science and technology. It played a crucial role in the development of future space missions, including the International Space Station (ISS), by providing valuable experience in long-duration spaceflight.
