Area of Science:

  • Space Medicine
  • Psychology
  • Human Physiology

Background:

  • Simulation studies are crucial for understanding crew dynamics during prolonged isolation.
  • International Space Station (ISS) crews will comprise international astronauts living in separate modules but sharing joint protocols.
  • Anticipating crew problems requires data from simulated long-duration confinement.

Purpose of the Study:

  • To investigate physiological parameters, specifically catecholamine excretions, during simulated ISS flight.
  • To evaluate the relationship between epinephrine/norepinephrine levels and group dynamics.
  • To predict adverse changes in health and work capability linked to psychological interactions in isolation.

Main Methods:

  • Studied two simultaneously functioning groups in a hermetic chamber simulating ISS flight conditions.

  • Monitored physiological parameters, including catecholamine excretions (epinephrine and norepinephrine).
  • Assessed group dynamics and social events to correlate with physiological data.

    • Main Results:

    • Physiological parameters such as catecholamine excretions were investigated in relation to confinement.
    • The study aimed to establish links between hormonal changes and group interactions.
    • Data was collected to predict potential health and work capability issues.

    Conclusions:

    • Understanding physiological responses to isolation is key for astronaut well-being.
    • Correlating catecholamine levels with social dynamics can help identify risks in confined environments.
    • This research contributes to predicting and mitigating challenges for future long-duration space missions.
