Area of Science:

  • Space medicine
  • Human physiology
  • Vestibular system

Background:

  • Space motion sickness impacts a significant percentage of astronauts and cosmonauts.
  • It shares etiological factors with terrestrial motion sickness.
  • Understanding spatial orientation and sensory-motor adaptation is key to predicting causes.

Purpose of the Study:

  • To investigate the factors contributing to space motion sickness.
  • To explore the relationship between individual susceptibility and adaptation rates.
  • To correlate susceptibility during microgravity with vestibular function.

Main Methods:

  • Analyzing etiological factors of space motion sickness.
  • Assessing individual variability in susceptibility and adaptation.
  • Relating microgravity motion sickness to vestibular function under 1G and 0G conditions.

Main Results:

  • Space motion sickness is influenced by multiple etiological factors.
  • Individual susceptibility varies, but adaptation rates are relatively consistent.
  • Vestibular function under different gravity conditions is being investigated in relation to susceptibility.

Conclusions:

  • Space motion sickness is a complex condition with multifactorial causes.
  • Individual differences in adaptation are notable.
  • Further research aims to link vestibular function to space motion sickness susceptibility.
