Miniaturizing the Earth's biogeochemical cycles to support human life during future space missions is the goal of the NASA research and engineering program in advanced life support. Mission requirements to reduce mass, volume, and power have focused efforts on (1) a maximally simplified agro-ecosystem of humans, food crops, and microbes; and, (2) a design for optimized productivity of food crops with high light levels over long days, with hydroponics, with elevated carbon dioxide and other controlled environmental factors, as well as with genetic selection for desirable crop properties. Mathematical modeling contributes to the goals by establishing trade-offs, by analyzing the growth and development of experimental crops, and by pointing to the possibilities of directed phasic control using modified field crop models to increase the harvest index.
将地球生物地球化学循环小型化以在未来太空任务期间支持人类生命，这是美国国家航空航天局先进生命支持研究与工程项目的目标。减少质量、体积和功率的任务要求，已将工作重点放在：（1）人类、粮食作物和微生物的最大限度简化的农业生态系统；以及（2）一种设计，该设计通过水培法、提高二氧化碳水平及其他可控环境因素，以及通过对理想作物特性进行基因选择，来实现长日照高光水平下粮食作物的优化生产力。数学建模通过建立权衡关系、分析实验作物的生长和发育以及指出使用改良大田作物模型进行定向阶段控制以提高收获指数的可能性，来推动这些目标的实现。
