Exploration missions are characterized as having increased crew autonomy, communication delays, reduced support from ground control, and limited resupply opportunities. In addition to these exploration mission attributes, microgravity and mission duration, pose unique stressors to the human physical state (e.g., spinal elongation) and cognitive capability. The impact of these mission characteristics to crew performance and to vehicle/habitat design is unknown.

Current data suggest that long-duration crewmembers may suffer performance decrements due to the spaceflight environment (spatial disorientation, cognitive and perceptual changes, sleep loss, fatigue, deconditioning, workload). Spaceflight crews will also demand more from their habitat and human-computer interfaces due to the increased autonomy that will be characteristic of long-duration missions. Current guidelines may be inadequate to mitigate these factors.

Currently we do not know the acceptable threshold or ranges for habitable volume and the preferred internal layout for a vehicle/habitat for a given set of mission attributes (e.g. volume relative to extended mission duration). There are a number of guidelines and measurement techniques for designing and assessing vehicles/habitats that need to be developed and validated for predetermined mission attributes.

Future spacecraft will need to accommodate long-duration spaceflight conditions, and the resultant impacts to human performance. Many operations are moving toward portable computing solutions that take advantage of multiple modalities (visual, auditory, tactile). Identifying thresholds is critical.

Development and validation of tools and guidelines for informing habitat design; performance evaluation relative to various volume and habitat configurations over extended mission durations; assessment of performance based on changes in  displays and under varying modal conditions; analog and flight data collection that integrate physiological and behavioral changes in relevant conditions, to inform development of adaptive displays and ‘smart’ habitability features (e.g. lighting) in future vehicles are approaches needed for addressing this gap. 

Target for Closure
  1. Tools and guidelines for habitat design development including HCI standards, guidelines and recommendations; 
  2. Evidence based guidelines and validated countermeasures relative to habitability and interface design, to mitigate impacts of the spaceflight environment on operational performance.
Risk Risk of Adverse Outcome Due to Inadequate Human Systems Integration Architecture
You are here! Gap HSIA-401: We need to determine how HSI can be applied in the vehicle/habitat and computer interface Design Phase to mitigate potential decrements in operationally-relevant performance (e.g. problem-solving, execution procedures), during increasingly earth-independent, future exploration missions (including in-mission and at landing).
