神舟二十三号乘组开展脑电、触觉与精细动作测试

中国载人航天工程办公室11月8日发布的在轨记录显示，神舟二十三号三名航天员使用脑电采集设备，开展涉及脑网络和视觉运动加工的测试，并进行了触觉感知与力量控制实验。这些数据将用于研究长期太空飞行过程中，脑功能网络、手部感知与精细动作控制如何变化。此轮披露的是实验任务进展，分析结果尚待研究。

乘组同时维护多项微重力物理实验设施，包括清理无容器实验柜腔体、更换样品、维护轴心机构电极，以及检查两相系统实验柜。常规保障项目还有舱内压力服检查、应急救生训练以及温度和风速测量。健康监测方面，航天员接受了视功能、眼压、眼底及经眶超声检查，并使用在轨身体质量测量装置追踪微重力环境下的身体变化。这些工作覆盖三个并行环节，航天员担任实验受试者、维护科学载荷，以及检查空间站日常运行状态。
