MOFFETT FIELD, Calif. (NASA PR) — The Advanced Exploration Systems’ (AES) Autonomous Systems and Operations (ASO) team, including members from NASA Ames’ Intelligent Systems Division, developed and demonstrated new technologies designed to automate the operation of Gateway, a key element of the Artemis mission. (Gateway will be an outpost orbiting the Moon that provides vital support for a long-term human return to the lunar surface, as well as a staging point for deep space exploration.)

These novel technologies are designed to perform tightly integrated planning, plan execution, fault detection, fault impacts reasoning, and fault recovery on the spacecraft power distribution system and life support systems. The ASO team demonstrated fault-isolation and ‘most functional state’ restoration capabilities, and infused this technology into the Gateway Program’s Vehicle Systems Management Design Team at Johnson Space Center for subsequent development and maturation as part of the Gateway flight software.

The demonstration scenario featured replanning of a spacecraft “burn” (firing of its onboard rocket motors) after a fault. The replanned burn causes numerous disruptions to the mission timeline, requiring replanning. This year’s work leveraged prior years’ efforts, ...
