Response to caloric stimulation was examined in two subjects in the weightless environment of orbital flight. Using air insufflation, a binaural temperature stimulus profile was performed twice on each subject during flight. In all but one test, which was carried out on the first mission day, a caloric nystagmus was registered. This zero-g nystagmus was similar to ground-based pre- and postflight responses with regard to its intensity, its temporal correlation with the stimulus profile (nystagmus was always directed towards the warmer ear) and the subjective sensations reported by the tested subjects. These findings demonstrate that mechanisms other than thermoconvection are involved in the elicitation of the caloric nystagmus response. At each stage of the temperature stimulus profile, linear acceleratory stimulation was presented in the form of oscillations in the X-axis. Some differences were found between one-g and zero-g conditions in the resultant modification of the nystagmus response.
在轨道飞行的失重环境中，对两名受试者的热刺激反应进行了检测。在飞行过程中，通过空气吹入对每位受试者进行了两次双耳温度刺激曲线测试。除了在首个任务日进行的一次测试外，在所有测试中均记录到了冷热性眼震。这种零重力眼震在强度、与刺激曲线的时间相关性（眼震总是指向较热的耳朵）以及受试受试者报告的主观感受方面，与地面飞行前和飞行后的反应相似。这些发现表明，热对流以外的机制参与了冷热性眼震反应的诱发。在温度刺激曲线的每个阶段，以X轴振荡的形式施加线性加速度刺激。在1g和零重力条件下，眼震反应的最终变化存在一些差异。
