Space Architecture is the theory and practice of designing and building inhabited environments in outer space (it encompasses architectural design of living and working environments in space related facilities, habitats, and vehicles). These environments include, but are not limited to: space vehicles, stations, habitats and lunar, planetary bases and infrastructures; and earth based control, experiment, launch, logistics, payload, simulation and test facilities. Earth analogs to space applications may include Antarctic, airborne, desert, high altitude, underground, undersea environments and closed ecological systems. Designing these forms of architecture presents a particular challenge to ensure and support safety, sustainability, habitability, reliability, and crew efficiency, productivity and comfort in the context of extreme environments.
