Space settlements are habitats designed for humans to live and work in outer space. These structures can be built on celestial bodies like the Moon or Mars, or in orbit around Earth. They aim to support long-term human presence beyond our planet, providing essential resources like air, water, and food. The concept of space settlements often involves advanced technologies, such as solar power and life support systems. Notable proposals include the O'Neill Cylinder, which envisions rotating habitats to create artificial gravity. As space exploration advances, the idea of establishing permanent communities in space becomes increasingly feasible.
