JSC Rapid Prototyping Lab To Conduct Joint Fault Management Simulation With Orion Crew and Flight Controllers

On February 10, the Rapid Prototyping Lab (RPL) at Johnson Space Center (JSC) will conduct a joint simulation of crew onboard the Orion spacecraft and flight controllers managing faults. The simulation will be conducted with astronauts (JSC CB/Astronaut Office) and Flight Operations Directorate staff (JSC CA and CM). The simulation will employ the current Orion cockpit displays and electronic procedures, and the Advanced Caution and Warning System (ACAWS) software evaluated during Exploration Flight Test 1 (EFT-1).

The simulation will include a series of faults in the Orion electrical system that 1) force the crew to work through procedures, and 2) force flight controllers to evaluate faults. The purpose of the simulation is to begin understanding how flight control and crew will work together using the novel technologies developed for Orion; these technologies and the associated protocols will be developed further for Exploration Mission 2 (the first human return to the Moon). Over the past month (and continuing through testing), this joint simulation has been showcased to a variety of high-profile visitors at JSC, including Astronaut Office rep Rex Walheim, JSC Center Director Ellen Ochoa, former ARC Center Director Scott Hubbard, and Advanced Exploration Systems Point Of Contact Richard McGinnis.

BACKGROUND: The goal of the Advanced Caution and Warning System (ACAWS) task is to develop essential technology that enables deep-space mission crews to more effectively handle off-nominal conditions. On deep-space missions, round-trip communication time delay makes it impossible to close the loop with Mission Control on Earth prior to taking critical actions. Even a small number of round-trip communications necessary for Earth-based mission control to provide guidance can exceed failure time to criticality. The ACAWS integrated suite of intelligent system technologies can provide crew support to identify the problems, decide when to take actions, and what actions to take. Determining what parts of the system are affected by failures – either becoming disabled or losing a level of redundancy – is a critical precursor to correcting a problem. ACAWS leverages the efforts of creating a diagnostic model of a system to reason about the propagation of failures through the system.
