NASA is developing preflight adaptation trainers (PATs) to help astronauts adapt to microgravity and return to Earth. These trainers aim to reduce sensory disturbances and Space Motion Sickness (SMS).

Area of Science:

  • Aerospace Medicine
  • Human Factors Engineering
  • Neuroscience

Background:

  • Astronaut adaptation to microgravity and readaptation to Earth present significant challenges.
  • Sensory and sensorimotor disturbances, including Space Motion Sickness (SMS), are common issues.
  • Current countermeasures are being enhanced to mitigate these effects.

Purpose of the Study:

  • To develop and describe two part-task preflight adaptation trainers (PATs).
  • To preadapt astronauts to novel sensory stimuli mimicking microgravity conditions.
  • To facilitate adaptation to microgravity and improve readaptation to Earth's gravity.

Main Methods:

  • Discusses design principles for two novel PAT devices.
  • Presents a detailed description of the two PAT devices.

  • Summarizes four ground-based investigations using a PAT to assess sensory stimulus effects.

    • Main Results:

    • Investigated changes in compensatory eye movements, postural equilibrium, and motion sickness symptoms.
    • Evaluated electrogastroic responses under various novel sensory stimulus conditions.
    • The PAT effectively simulated conditions to study astronaut adaptation.

    Conclusions:

    • Preflight adaptation trainers are crucial for minimizing sensory and sensorimotor disturbances.
    • The PATs support the concept of dual-adapted states for spaceflight.
    • Ongoing research will further refine these countermeasures for future missions.
