Space Motion Sickness and Vestibular Experiments in Spacelab 820833
Approximately 43 percent of Apollo, Skylab, Soyuz/Salyut and Shuttle crewmen have experienced symptoms resembling motion sickness during their first several days in space. This paper reviews the the space sickness problem in both an operational and physiological context, and describes experiments planned by a team of vestibular researchers from the USA and Canada to study apace sickness and associated sensory-motor adaptation to weightlessness during Spacelab missions 1 and 4, and the German Spacelab mission D-1.
