Vestibular Reactions to Spaceflight: Human Factors Issues

Aviat Space Environ Med. 2000 Sep;71(9 Suppl):A100-4.


Vestibular function, along with other sensory systems influencing spatial orientation, can have a profound influence on the ability of astronauts to function effectively. Beyond the well-known problems of space motion sickness, vestibular effects can influence astronaut well-being and performance during all phases of a space mission. This paper discusses some of the major vestibular reactions affecting human factors encountered in all space missions, and covers them chronologically in the following sequence: launch, early on-orbit, late on-orbit, EVA, artificial gravity, re-entry, and post-landing.
