A Moon Base is a planned or existing facility on the surface of the Moon designed for human habitation and scientific research. It aims to support astronauts for extended periods, allowing them to conduct experiments, explore the lunar environment, and prepare for future missions to other celestial bodies, such as Mars. These bases may include living quarters, laboratories, and systems for generating power and recycling air and water. Various space agencies, including NASA and ESA, are exploring technologies and designs for sustainable lunar habitats, which could serve as a stepping stone for deeper space exploration.
