A space colony is a human settlement located in outer space, typically on a celestial body like the Moon or Mars. These colonies are designed to support human life by providing essential resources such as air, water, and food. They often utilize advanced technology to create sustainable living environments, allowing people to live and work in space for extended periods. The concept of space colonies has been popularized by science fiction and is being explored by organizations like NASA and private companies such as SpaceX. Research into space habitats focuses on overcoming challenges like radiation exposure, microgravity effects, and resource management to ensure the safety and well-being of inhabitants.
