Cognitive performance, fatigue, emotional and physiological strains in simulated long-duration flight missions

Crew fatigue during simulated, long duration B-1B bomber missions.

Crew fatigue associated with successive and unaugmented 36 h missions was evaluated in B-1B simulators. Data were obtained from 32 operationally qualified crewmembers. All crew-members completed three consecutive, long duration missions, each preceded by 33 to 35 h of crew rest. Oral temperature, salivary melatonin and cortisol, as well as actigraph and subjective measures, were collected durin...

Dynamic Modeling of Crew Performance for Long-Duration Space Missions

Activity Planning for Long Duration Space Missions

For long duration, manned exploration to be cost-effective, it is necessary to automate routine manual operations. To enable such automated control, activity plans must coordinate the activities of the crew with other automated “agents” including robots, life support systems, and vehicle systems. An important challenge is assisting the crew in using automated planning software to construct and ...

Artificial gravity as a countermeasure for mitigating physiological deconditioning during long-duration space missions

In spite of the experience gained in human space flight since Yuri Gagarin's historical flight in 1961, there has yet to be identified a completely effective countermeasure for mitigating the effects of weightlessness on humans. Were astronauts to embark upon a journey to Mars today, the 6-month exposure to weightlessness en route would leave them considerably debilitated, even with the impleme...

Goal-Driven Autonomy and Robust Architecture for Long-Duration Missions

During the most recent period of performance, the team has refined the major implemented functions of our MIDCA architecture at the cognitive level (Cox, 2013; Paisner, Cox, Maynord, & Perlis, 2014) and has started work on an analogous metacognitive cycle at the meta-level (Dannenhauer, Cox, Gupta, Paisner & Perlis, 2014; Perlis & Cox, 2014). We produced substantial progress on the knowledge-ri...
