Biomedical findings in the area of space motion sickness of the Skylab missions are reviewed and compared with the results of laboratory simulations. The motion sickness experiences of the three Skylab crews are related, and it is pointed out that of the nine astronauts, four were not sick at all, and of the five who were sick, only two vomited. In addition, it is noted that soon after recovery all five were immune in a provocative test based on the generation of cross-coupled angular accelerations while they executed head movements during rotation, in which they had manifested symptoms before the flight. Is is concluded that the findings indicate that susceptibility to motion sickness on earth is not a reliable predictor of susceptibility to motion sickness in orbit, and that free fall is a partial motion environment. Difficulties in dealing with motion sickness under operational conditions and the limitations of antimotion sickness remedies are noted.
