The International Space Station is a modular, continuously occupied research facility orbiting Earth, designed to serve as a microgravity laboratory for advanced scientific investigation. Its structure comprises interconnected modules and external truss segments, allowing for various experiments across multiple disciplines. Research conducted aboard the station focuses on areas such as life sciences, advanced physics, materials science, and astronomy, particularly studying biological responses and material behavior in the vacuum of space. The system relies on complex life support technologies, including regenerative systems for air and water reclamation, and utilizes precise orbital mechanics to maintain its operational altitude and stable trajectory.
