A space station is a large spacecraft that remains in low Earth orbit, allowing astronauts to live and work in space for extended periods. These stations are equipped with life support systems, laboratories, and living quarters, enabling scientific research and experiments in microgravity. The most well-known space station is the International Space Station (ISS), which is a collaborative project involving multiple countries. Space stations serve as platforms for studying various scientific fields, including biology, physics, and astronomy. They also provide valuable experience for future long-duration missions to other celestial bodies, such as Mars. By conducting research in space, scientists can gain insights that are not possible on Earth.
