Human space flight missions often requires long-term isolation of crewmembers in extreme environments. The space flight environment introduces stressors to both crewmember physiology and behavioral psychology. Specific human-factors stressors include long-duration isolation, sleep loss, circadian desynchronization, and high workload. These present a real, tangible risk of performance decrements, which could have significant negative impacts on the mission objectives. Research conducted in space flight analogs such as NASA’s Human Exploration Research Analog (HERA) provide a unique opportunity to study these effects, in a larger sample size than International Space Station (ISS) crews, and develop essential metrics to identify and prevent performance decrements in an operationally-relevant setting.

In the field of human space flight, real-time performance metrics and the quantification of performance during operationally-relevant tasks and scenarios have the potential to make existing operations safer and more efficient, and improve the design of future vehicles. The identification of critical performance decrements, either in measures of task performance, workload, or situational awareness, may be used to alter the human-automation task allocation or suggest changes to crew resource management.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
