Gateway Management through Adaptive, Autonomous, Fault Identification & Diagnosis and Reconfiguration/Replanning/Rescheduling Optimization

The lunar Gateway is a lunar space station that will orbit the Moon in a highly elliptical Near-Rectilinear Halo Orbit (NRHO). The Gateway is envisioned as a multi-purpose spacecraft serving as a temporary habitat for astronauts, a science laboratory (for crewed and un-crewed experiments), a communications store/relay, a holding area for other spacecraft and devices, etc. The Gateway requires autonomous system and operations management, including the ability to follow commands (from ground stations and astronauts), fault/degradation detection and diagnosis; warnings, recovery; preventative/precautionary measures; and more. The Gateway includes many subsystems such as the Electrical Power System (EPS) and Communications. The EPS underlies much of the PPE, the HAO, and the Gateway as a whole.nbsp;We propose Gateway-MAESTRO (GatewayManagement throughnbsp;AdaptivE, autonomous, faulTidentification amp; diagnosis,nbsp;Reconfiguration/replanning/reschedulingOptimization) to manage the Gateway system and operations.nbsp;During normal operations, Gateway-MAESTRO monitors onboard sensor values in order to: automatically characterize Gateway components and to be prepared to detect failures; based on that characterization, automatically predict resource availability over time; and automatically schedule the actions (i.e., determine what activities will occur and when (along with the modes of the associated equipment)). During a failure scenario, Gateway-MAESTRO would first detect the problem; immediately safe the spacecraft to minimize damage; diagnose the problem and determine the root cause; determine potential feasible courses of action (COAs) given the failed components or set of possible failed components; determine the impact and ramifications of each COA; select the most appropriate COA; generate the detailed schedule/sequence of actions to implement the COA; and finally adaptively execute the required actions.
