Space motion sickness is a significant operational concern in the American and Soviet space programs. Nearly 70% of all astronauts and cosmonauts are affected to some degree during their first several days of flight. It is now beginning to appear that space motion sickness like terrestrial motion sickness is the consequence of multiple etiological factors. As we come to understand basic mechanisms of spatial orientation and sensory-motor adaptation we can begin to predict etiological factors in different motion environments. Individuals vary greatly in the extent to which they are susceptible to these different factors. However, individuals seem to be relatively self-consistent in terms of their rates of adaptation to provocative stimulation and their retention of adaptation. Attempts to relate susceptibility to motion sickness during the microgravity phases of parabolic flight maneuvers to vestibular function under 1G and 0G test conditions are described.
太空晕动病是美国和苏联太空计划中的一个重大操作问题。近70%的宇航员在飞行的头几天都会受到不同程度的影响。现在看来，太空晕动病与地面晕动病一样，是多种病因的结果。随着我们开始了解空间定向和感觉运动适应的基本机制，我们可以开始预测不同运动环境中的病因。个体对这些不同因素的易感性差异很大。然而，个体在对刺激性刺激的适应率和适应的保持方面似乎相对一致。本文描述了在抛物线飞行机动的微重力阶段，将晕动病易感性与1G和0G测试条件下的前庭功能联系起来的尝试。
