The Habitat Automation (HA) team integrated three existing tools that were previously developed in Code TI: The Advanced Caution and Warning System (ACAWS), the Extensible Universal Remote Operations Planning Architecture (EUROPA) automated planner, and the Scheduling and Planning Interface for Exploration (SPIFe). During the demonstration, the user operated the ACAWS Graphical User Interface (GUI) to select a failure in the Deep Space Habitat (DSH). The Failure Consequence Assessment System (FCAS), which is part of ACAWS, then automatically determined the impacts of this failure. The impacts are the components that have not failed, but have stopped functioning because of a failure in another component. For example, when a Power Distribution Unit (PDU) fails, all of the components that are powered by the PDU are impacted.
The impacts were displayed in the ACAWS GUI, and also communicated to EUROPA. EUROPA determined which of the scheduled crew activities would be impacted by the loss of capability, and annotated the impacted activities in the crew schedules displayed in SPIFe. Finally, EUROPA replanned and rescheduled crew activities to include a repair of the failed component. The updated crew schedules were also displayed in SPIFe. This demonstration completed a controlled milestone for the Game Changing Development (GCD) program.
BACKGROUND: The Habitat Automation (HA) project element is building technology to automate the operations of a future habitat in which people could live on the surface of a moon, planet, or asteroid, or in deep space on the way to and from such destinations. An important part of habitat automation is the ability to automatically detect and diagnose failures in habitat systems, and to then automatically respond to those failures.
The Deep Space Habitat (DSH) is a prototype of a future habitat that could be used to house astronauts. It was developed by the Advanced Exploration Systems (AES) Deep Space Habitat project.
