An orbital habitat is a living space designed for humans to reside in while orbiting Earth or other celestial bodies. These habitats are built to provide essential life support systems, including air, water, and food, while protecting inhabitants from space radiation and microgravity effects. Examples include the International Space Station (ISS), which serves as a research facility and living quarters for astronauts. Orbital habitats can vary in size and complexity, ranging from small modules to larger structures that can support multiple crew members for extended periods. They are crucial for future space exploration missions, such as those planned for Mars and beyond, as they enable long-term human presence in space.
