Crew Decision Systems Group Demonstrates Integrated System On Desert Rats’ Deep Space Habitat

The Advanced Caution and Warning Systems (ACAWS) and Discrete Controls (DC) teams demonstrated an integrated system on the Habitat Demonstration Unit (HDU) - Deep Space Habitat (DSH) at the Desert Research and Technology Studies (D-RATS) site. ACAWS and DC technologies are critical for enabling crew autonomy for deep-space missions by decreasing the requirements for real-time communication with ground-based flight controllers. The technologies demonstrated included automated system health monitoring, automated diagnosis, automated recommendation of malfunction procedures, human interaction with troubleshooting and repair procedures using an electronic procedure viewer, and automated execution of repair procedures. ACAWS was used to support field operations in the on-site mission support tent, successfully alerting operators to inoperative equipment. The SHIELD systems were evaluated by the HDU test conductor and the ACAWS JSC/MOD customer representative on injected failures inside the HDU; a human-factors analysis of the results is underway.

Specific tools used include the Inductive Monitoring System (IMS), developed by NASA/ARC; Qualtech Systems, Inc. (QSI) TEAMS-RDS, developed in collaboration with NASA/ARC through Small Business Innovation Research (SBIR) funding; and Procedure Display (PD) and Universal Executive (UE), collaboratively developed by NASA/JSC and NASA/ARC.

BACKGROUND: NASA’s Desert Research and Technology Studies (D-RATS) team evaluates technology, human-robotic systems, and extravehicular equipment in the high desert near Flagstaff, Arizona. Field testing provides a knowledge base that helps scientists and engineers design, build, and operate better equipment, as well as establish requirements for operations and procedures.

The Advanced Caution and Warning System (ACAWS) is a fault management tool that combines dynamic and interactive graphical representations of spacecraft systems, systems modeling, automated diagnostic analysis and root cause identification, system and mission impact assessment, procedure and flight rule identification, and interaction with other tools to help spacecraft flight controllers and crew understand and respond to anomalies more effectively. Each of these capabilities provides critical support in monitoring the performance of vehicle systems as well as supporting the real-time decision process of Mission Control Center (MCC) flight controllers and crew in dealing with spacecraft anomalies and failures. In addition to real-time mission support, ACAWS’ capability to create and interact with malfunction scenarios will support the analysis and training tasks associated with spacecraft operations.

The goal of Discrete Control (DC) Technology is to command robots, spacecraft, or spacecraft systems according to a previously developed plan. DC’s electronic procedure system can be used with an operator-settable level of automation, providing a spacecraft autonomy environment in which procedures can be executed by an operator, by a computer with operator consent, or automatically by a computer.
