使用等效系统质量（ESM）的方法，其中所有重要的成本转换为质量单位的火星任务的生命支持方法进行评估。由最低使命无害环境管理界定的最佳办法取决于若干使命参数，特别是持续时间、环境和随之而来的基础设施成本、乘员人数以及现有技术的特点。一般来说，对于所审议的飞行任务，物理化学再生是最具成本效益的。然而，生物再生很可能用于生产任何使命所需的色拉作物，用于生产中期任务所需的主食作物，以及用于长期任务（持续十年）所需的大多数食物、空气和水的再生。需要进一步考虑就地资源利用的潜在应用。(C)2002年由Elsevier Science Ltd代表空间研委会出版。
Life support approaches for Mars missions are evaluated using an equivalent system mass (ESM) approach, in which all significant costs are converted into mass units. The best approach, as defined by the lowest mission ESM, depends on several mission parameters, notably duration, environment and consequent infrastructure costs, and crew size, as well as the characteristics of the technologies which are available. Generally, for the missions under consideration, physicochemical regeneration is most cost effective. However, bioregeneration is likely to be of use for producing salad crops for any mission, for producing staple crops for medium duration missions, and for most food, air and water regeneration for long missions (durations of a decade). Potential applications of in situ resource utilization need to be considered further. (C) 2002 Published by Elsevier Science Ltd on behalf of COSPAR.
