Space habitats are structures designed for humans to live and work in outer space. They provide essential life support systems, including air, water, and food, while protecting inhabitants from harsh environmental conditions like radiation and extreme temperatures. Examples of space habitats include the International Space Station (ISS) and future concepts for lunar or Martian bases. These habitats can be temporary or permanent and are crucial for long-term space exploration. They are equipped with sleeping quarters, laboratories, and recreational areas to support the physical and mental well-being of astronauts. Research in space habitats helps scientists understand how to sustain human life beyond Earth.
