The Importance of Closed Loop Systems for Space Colonization

Closed loop systems are essential for sustaining human life in space habitats, as they recycle resources to minimize reliance on Earth. Experiments like Biosphere 2 aimed to create self-sufficient ecosystems where everything, including air and food, is produced internally. However, early attempts revealed significant challenges, such as inadequate food production and nutritional deficiencies when trapped in a sealed environment. These experiments underscore the necessity of developing efficient closed loop systems for future Mars colonization efforts, where food production and resource recycling will be critical to survival.
