Recently, the Shenzhou-20 astronaut crew publicly recounted a near-miss incident they encountered during their mission shortly after returning to Earth. According to mission commander Li Ming, during an extravehicular activity (EVA), one astronaut’s spacesuit communication system suddenly failed, causing a brief loss of contact with both the space station and ground control. Facing this emergency, the crew swiftly activated contingency protocols, using hand signals and backup communication equipment to coordinate effectively. Within 15 minutes, they successfully reestablished communication and safely returned to the cabin. Although the incident did not significantly impact the overall mission, it highlighted the critical importance of emergency response capabilities in human spaceflight. The China Manned Space Agency stated that a thorough review of the incident has been conducted, and improvements to spacesuit design and training procedures will be implemented to enhance safety margins for future missions. The astronauts emphasized that their rigorous, high-fidelity daily training enabled them to remain calm and resolve the crisis effectively. This experience served not only as a technical test but also as a real-world validation of China’s space station operational readiness.
近日，神舟二十号航天员乘组在返回地球后首次公开回忆了任务期间遭遇的一次太空险情。据指令长李明介绍，在执行舱外活动（EVA）过程中，一名航天员的舱外服通信系统突发故障，导致其与空间站及地面控制中心短暂失联。面对突发状况，乘组迅速启动应急预案，依靠手势信号和备用通信设备协同配合，最终在15分钟内成功恢复联络并安全返回舱内。此次事件未对任务整体造成重大影响，但凸显了载人航天任务中应急处置能力的重要性。中国载人航天工程办公室表示，已对相关系统进行复盘分析，并将进一步优化舱外服设计与训练流程，以提升未来任务的安全冗余。航天员们强调，正是日常高强度、高仿真的训练，才使他们在关键时刻能够冷静应对、化险为夷。这次经历不仅是一次技术考验，更是对中国空间站常态化运营能力的一次实战检验。
