Operation-Aware ISHM for Environmental Control and Life Support in Deep Space Habitants

A life support systems’ reliability and survivability are critical to NASA especially in long-term space exploration missions. The Health Management of life support systems consists of several components among which power, water recovery, and biomass processing systems etc. which are of primary importance. Due to the crew’s critical dependence on such a complex system, the health management of life support systems becomes crucial to NASA’s mission success rates. In Phase I, we focus on the WRS system for proof-of-concept of ACM system. In Phase II, the work will be expanded to full scale LSS, including WRS, oxygen, food generation, waste processing, air revitalization, biomass production, etc. This will yield a system model which involves mechanical, electrical, hydraulic, chemical and biological components. We will also leverage existing models, such as BioSim, HabNet, V-HAB . With the LSS model, we will fully mature and develop the ACM system, which integrates data driven modeling, sensor/component failure isolation, hierarchical ACM system, and dynamic case-based reasoning.
