Area of Science:

  • Spaceflight physiology
  • Neuroscience
  • Human factors in aerospace

Background:

  • Commercial suborbital flights offer brief microgravity exposure.
  • Passengers will experience significant sensorimotor challenges due to rapid transitions between hypergravity and zero gravity.
  • Previous research in parabolic and orbital flights indicates a high likelihood of neurovestibular disturbances.

Purpose of the Study:

  • To identify potential sensorimotor challenges for suborbital passengers.
  • To propose pre-flight adaptation protocols to mitigate these challenges.
  • To establish a method for evaluating passenger readiness for spaceflight.

Main Methods:

  • Development of sensorimotor tests including angular vestibulo-ocular reflex (VOR), ocular skew, subjective visual vertical, and roll vection assessment.

  • Correlation of pre-flight test performance with in-flight experiences (motion sickness, disorientation).
  • Utilizing questionnaires and cabin video recordings for in-flight data collection.

    • Main Results:

    • Pre-flight sensorimotor tests can identify individuals susceptible to spaceflight-induced disturbances.
    • Understanding adaptation to microgravity from prior research informs protocol development.
    • Potential correlations between specific sensorimotor deficits and reported in-flight symptoms were investigated.

    Conclusions:

    • Pre-flight sensorimotor evaluation is crucial for preparing passengers for suborbital spaceflight.
    • Tailored adaptation protocols based on test results may reduce adverse effects.
    • Further research can refine these protocols for enhanced passenger safety and experience.
