This compendium, written by active researchers in the field, encompasses topics ranging from anatomical and physiological subjects, through analyses of stimulus characteristics, prediction of sickness, and consideration of human factors, to pharmacological and behavioral therapeutic measures for terrestrial as well as microgravity travelers. Material often found scattered in diverse journals, paper-bound proceedings of symposia, difficult-to-find laboratory reports, or included with other topics in collections having a diffuse focus, are presented here in one volume dedicated to a single theme. The critical up-to-date- reviews are a first source for researchers and research program managers as well as an essential information source for engineers and practitioners.
This report contains a summary review of space and motion sickness, comment on the current and projected NASA research program, and the conclusions and suggestions of the ad hoc Working Group. The frame of reference for the report is ground-based research.

The objective of this proposal is to determine the relationship of motion sickness susceptibility to vestibulo-ocular reflexes (VOR), motion perception, and behavioral utilization of sensory orientation cues for the control of postural equilibrium. The work is focused on reflexes and motion perception associated with pitch and roll movements that stimulate the vertical semicircular canals and otolith organs of the inner ear. This work is relevant to the space motion sickness problem since 0 g related sensory conflicts between vertical canal and otolith motion cues are a likely cause of space motion sickness. Results of experimentation are summarized and modifications to a two-axis rotation device are described. Abstracts of a number of papers generated during the reporting period are appended.

The objectives of this project were to explore systematically the determiners of transfer of perceptual adaptation as these principles might apply to the space adaptation syndrome. The perceptual experience of an astronaut exposed to the altered gravitational forces involved in spaceflight shares much with that of the subject exposed in laboratory experiments to optically induced visual rearrangement with tilt and dynamic motion illusions such as vection; and experiences and symptoms reported by the trainee who is exposed to the compellingly realistic visual imagery of flight simulators and virtual reality systems. In both of these cases the observer is confronted with a variety of inter- and intrasensory conflicts that initially disrupt perception, as well as behavior, and also produce symptoms of motion sickness.

Reviews the space sickness problem in both an operational and psychological context. Describes experiments planned by a team of vestibular researchers from the USA and Canada to study space sickness and associated sensory-motor adaption to weightlessness during space-lab missions 1 and 4, and the German spacelab mission D-1.
