Current Research
Physics-Based Diagnosis Model and Digital Twin Simulation for Space Habitats
Duration: Aug, 2024 - May, 2028 (Ongoing)
Advisor: Prof. Daniel Selva
Institution: Texas A&M University, Systems Engineering, Autonomy and Knowledge Laboratory (SEAK)
Funding: NASA Human Research Program (Grant #80NSSC19K0656) & NASA STTR Phase II (Award #80NSSC24CA028)
Project Overview
This research focuses on developing autonomous anomaly resolution systems for space habitats using physics-based diagnostic models and digital twin simulations. The work is part of a larger effort to support astronauts during long-duration space exploration missions where communication delays with mission control make real-time support impossible.
Key Components
- Daphne-AT Virtual Assistant: A web-based application with natural language interface connected to real-time telemetry from NASA's Habitat Support System (HSS)
- Digital Twin Development: Real-time telemetry data assimilation into physics-based models to create habitat digital twins
- Multi-Agent Autonomous Anomaly Resolution System (MaARS): Integration with robotic agents for NASA's Gateway mission
- Anomaly Detection & Diagnosis: Physics-based reasoning capabilities for proactive anomaly detection and diagnosis
