NASA/JPL生命支持系统分析(LISSA)软件工具被用于执行月球前哨的生命支持系统分析和技术交易。生命支持系统是使用一个化学过程模拟程序建立的,每天一个人在稳态的基础上。LISSA模型的输入包括代谢平衡负荷数据、卫生负荷数据、技术选择、流程操作假设和任务参数假设。使用了一套基线技术,并通过运行22个具有技术替代的案例对其进行了比较。比较了4名机组人员以及90天和600天任务的系统、子系统和技术的重量和功率。通过给功率赋权重值,比较等价的系统权重。与基准相比,一些不太发达的技术显示出潜在的优势。固体废物处理技术显示出重量和电力方面的劣势,但人们可能会受益于减少危险废物和执行非常长的任务。建议发展技术,以减轻再补给的重量和更轻的建筑材料。还建议,由于技术是为开发提供资金的,应要求承包者生成和报告有助于进行定量技术比较的数据。
The NASA/JPL life support systems analysis (LISSA) software tool was used to perform life support system analysis and technology trades for a Lunar Outpost. The life support system was modeled using a chemical process simulation program on a steady-state, one-person, daily basis. Inputs to the LiSSA model include metabolic balance load data, hygiene load data, technology selection, process operational assumptions and mission parameter assumptions. A baseline set of technologies has been used against which comparisons have been made by running twenty-two cases with technology substitutions. System, subsystem, and technology weights and powers are compared for a crew of 4 and missions of 90 and 600 days. By assigning a weight value to power, equivalent system weights are compared. Several less-developed technologies show potential advantages over the baseline. Solid waste treatment technologies show weight and power disadvantages but one could have benefits associated with the reduction of hazardous wastes and very long missions. Technology development towards reducing the weight of resupplies and lighter materials of construction was recommended. It was also recommended that as technologies are funded for development, contractors should be required to generate and report data useful for quantitative technology comparisons.
