Studies of bioregenerative life support systems for use in space indicate that they are scientifically feasible. Preliminary data suggest that they would provide cost- and weight-saving benefits for low Earth orbit, long duration space platforms. Concepts of such systems include the use of higher plants and/or micro-algae as sources of food, potable water and oxygen, and as sinks for carbon dioxide and metabolic wastes. Recycling of materials within the system will require processing of food organism and crew wastes using microbiological and/or physical chemical techniques. The dynamics of material flow within the system will require monitoring, control, stabilization and maintenance imposed by computers. Future phases of study will continue investigations of higher plant and algal physiology, environmental responses, and control; flight experiments for testing responses of organisms to weightlessness and increased radiation levels; and development of ground-based facilities for the study of recycling within a bioregenerative life support system.
对用于太空的生物再生生命支持系统的研究表明，它们在科学上是可行的。初步数据表明，这些系统将为近地轨道、长期太空平台带来成本和重量节省方面的益处。此类系统的概念包括使用高等植物和/或微藻作为食物、饮用水和氧气的来源，以及作为二氧化碳和代谢废物的吸收体。系统内材料的循环利用将需要使用微生物学和/或物理化学技术处理食物生物体和船员废物。系统内物质流的动态变化将需要由计算机进行监测、控制、稳定和维护。未来的研究阶段将继续对高等植物和藻类的生理学、环境响应及控制进行研究；进行飞行实验以测试生物体对失重和辐射水平增加的反应；以及开发用于研究生物再生生命支持系统内循环利用的地面设施。
