Skylab vestibular experiments: motion sensitivity test in a rotary chair

(January 1,1972) The base houses the motor for the rotary chair. Skylab's Human Vestibular Function experiment (M131) was a set of medical studies designed to determine the effect of long-duration space missions on astronauts' coordination abilities. This experiment tested the astronauts' susceptibility to motion sickness in the Skylab environment, acquired data fundamental to an understanding of the functions of human gravity reception under prolonged absence of gravity, and tested for changes in the sensitivity of the semicircular canals. Data from this experiment were collected before, during, and after flight. The Marshall Space Flight Center in Redstone Arsenal, Alabama, had program management responsibility for the development of Skylab experiments.
