Motion sickness was studied in Skylab crewmen. By mission-day 8 (MD 8), astronauts were virtually free of motion sickness symptoms after rotation and linear acceleration tests. None of the Skylab-II astronauts (crewmen 1-3) was motion sick aloft, but astronaut 6 of the Skylab-III crew experienced motion sickness within an hour after transition into orbit. All three astronauts (4-6) of Skylab-III experienced motion sickness in the workshop, where astronaut 6 was most susceptible and astronaut 4 least susceptible. The higher susceptibility of SL-III crewmen in the workshop, as compared with SL-II crewmen, may be attributable to the fact that they were based in the command module (CM) less than one-third as long as were SL-II astronauts. I.e., the unnatural movements permitted in the open spaces of the workshop entrained more complex interactions of unusual vestibular and visual stimuli than did those in the CM. The observed reduced liability to kinetosis relative to earth may be due to absence of the gravity stimulus to the otolith organs.
