Long-duration future habitation of space involving great distances from Earth and/or large crew sizes (eg, lunar outpost, Mars base) will require a controlled ecological life-support system (CELSS) to simultaneously revitalize atmosphere (liberate oxygen and fix carbon dioxide), purify water (via transpiration), and generate human food (for a vegetarian diet). Photosynthetic higher plants and algae will provide the essential functions of biomass productivity in a CELSS, and a combination of physicochemical and bioregenerative processes will be used to regenerate renewable resources from waste materials. Crop selection criteria for a CELSS include nutritional use characteristics as well as horticultural characteristics. Cereals, legumes, and oilseed crops are used to provide the major macronutrients for the CELSS diet. A National Aeronautics and Space Administration (NASA) Specialized Center of Research and Training (NSCORT) was established at Purdue University to establish proof of the concept of the sustainability of a CELSS. The Biosphere 2 project in Arizona is providing a model for predicted and unpredicted situations that arise as a result of closure in a complex natural ecosystem.
未来在远离地球的太空进行长期居住以及/或者拥有大量人员规模（例如月球前哨站、火星基地），将需要一个受控生态生命支持系统（CELSS），以便同时实现空气再生（释放氧气并固定二氧化碳）、水净化（通过蒸腾作用）以及为人类生产食物（提供素食）。光合高等植物和藻类将在CELSS中发挥生物质生产力的基本功能，并且将结合物理化学和生物再生过程，从废料中再生可再生资源。CELSS的作物选择标准包括营养利用特性以及园艺特性。谷物、豆类和油籽作物用于为CELSS饮食提供主要的大量营养素。美国国家航空航天局（NASA）在普渡大学设立了一个专门研究与培训中心（NSCORT），以证明CELSS可持续性概念。亚利桑那州的生物圈2项目正在为复杂自然生态系统封闭后出现的可预测和不可预测情况提供一个模型。
