Future exploration missions will introduce unique stressors to spaceflight crews. These stressors are often categorized into five major hazards: hostile closed environment, distance from earth, isolation and confinement, radiation, and altered gravity. Evidence has shown that these hazards can lead to operationally-relevant performance changes; for example, Holden et al. (2019) have demonstrated that gravity transitions can impact fine motor skills needed to efficiently operate system features such as a touch screen, while communication delays, a hallmark of missions that will be distant from earth, have led to reported task inefficiencies and crew well-being (Kintz et al., 2016). More recent research is investigating potentially additive or synergistic effects of hazards concurrently, e.g. rodent research including radiation, isolation and confinement, and altered gravity. 

These stressors require unique and challenging considerations for vehicle/habitat environmental factors (e.g., vehicle layout design, net habitable volume, lighting and noise), and the development and integration of computer displays, automation, mission tasks and processes, and training regimens. 

The effects of these exploration-mission demands on crew performance has not been quantified. Defining how these demands will pose risk to crew health and performance serves as a fundamental step in defining risk mitigation, including both countermeasures for crew as well as system design to enable crew health and performance. 

The approach for addressing this gap will leverage existing and upcoming analog and flight research to assess performance demands relative to future missions and will identify solutions and tools to mitigate performance decrements in exploration mission scenarios (i.e. increasingly autonomous). The focus of the gap will  refine outcomes, measures and metrics HSIA-101 established, and results emerging within the context of this gap will inform subsequent countermeasure gaps relative to HSIA. 

Target for Closure
HSIA standards and guidelines for human performance requirements (including hab design, suited and unsuited crew under vibration, inventory management), Validated tools and guidelines using a case study/simulation (e.g., HERA, ISS, other analogs), updated standards and guidelines for Agency stakeholders/NASA documents (e.g., NASA-STD-3001, HIDH).
  1. Key risk factors relative to future mission demands characterized; 
  2. Countermeasures for mitigating performance identified. 
Risk Risk of Adverse Outcome Due to Inadequate Human Systems Integration Architecture
You are here! Gap HSIA-201: We need to evaluate the demands of future exploration habitat/vehicle systems and mission scenarios (e.g. increased automation, multi-modal communication) on individuals and teams, and determine the risks these demands pose to crew health and performance.
