Resource Management Strategies for a Resilient Habitat Advanced Life Support (ALS) System

The proposed framework and software are directly applicable to NASA’s Sustainability Base, Lunar Orbital Platform-Gateway, and the International Space Station to improve the resiliency by identifying and mitigating faults, improving operational effectiveness, and predict degradation. Long-term spaceflights and space habitats are characterized by increased complexity resultant from environmental, physical, and human-in-the-loop challenges that leads to operational uncertainty. The space habitat must be resilient to unexpected anomalies without the need for human intervention. We propose to develop a “resilient-by-design” framework demonstrated in a prototype toolkit. A digital twin simulation will be used as a virtual test bed for analyzing emerging energy technologies and future scenarios providing situational awareness. The framework will accommodate assured levels of performance, reliability, and resilience under the presence of uncertainty and sparsity in knowledge or data. The methodology to implement a resource management strategy will be based on novel probabilistic threshold conditions. Relevant fault metrics including false alarm rate, missing detection rate, and detection time will be assessed. The prototype software will be developed on the Trick Simulator / core Flight System platforms to facilitate easy transfer to current systems.

The proposed framework and software are directly applicable to NASA’s Sustainability Base, Lunar Orbital Platform-Gateway, and the International Space Station to improve the resiliency by identifying and mitigating faults, improving operational effectiveness, and predict degradation. The framework will recognize acceptable changes, extract relevant features, and establish conditions upon which to act. The software will be developed on the Trick Simulator / core Flight System platforms to facilitate easy transfer to current systems.

This technology would also be useful for disaster planning, e.g., FEMA, fire planning, and urban design, and to any organization working on a design for resilience systems including applications that require validation of different solutions with a focus on quick and effective decisions. We will pursue an aggressive commercialization strategy to bring the technology into market place.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
