Overview

Space habitats are engineered environments designed to support human life beyond Earth. These structures range from modules on the International Space Station (ISS) to conceptual models for lunar bases, Martian colonies, and free-floating orbital stations. Space habitats are central to the future of human space exploration, enabling long-duration missions and potential colonization of other celestial bodies.
