The translation of man from terrestrial to an extra terrestrial environment is accompanied by an upset in the servo-control of movement engendered by the removal of the normal gravitational signal. Unfortunately the "natural" response of the nervous system, to ocular and vestibular confusion, is to cause varying degrees of sickness which can only be avoided by choice of suitable space travellers i.e., those who are least upset by gravitational chaos. This will remain so until much more is learned about the fundamental physiological mechanisms whereby man maintains a correct head/trunk, head/eye, trunk/limb and eye/limb positional coordination and why if these are upset man's natural response is to vomit.
人类从陆地环境转移到地球外环境时，由于正常重力信号的消失，会导致运动的伺服控制失调。不幸的是，神经系统对视觉和前庭紊乱的“自然”反应是引发不同程度的恶心，只有挑选合适的太空旅行者，即那些受重力紊乱影响最小的人，才能避免这种情况。在更多地了解人类维持头部/躯干、头部/眼睛、躯干/四肢和眼睛/四肢位置协调的基本生理机制，以及为什么这些机制失调时人类的自然反应是呕吐之前，这种情况将一直存在。
