神20乘组讲述:返回地球前一天发现舷窗上有一个三角形,像是粘了片小树叶,用40倍显微镜才看清楚是裂纹
Xin Lang Cai Jing· 2026-02-16 08:47
陈冬:我的感觉是不是玻璃外面粘了一片小树叶,但是我后来马上就意识到不对,这是在太空,这怎么 可能有落叶呢? 记者:那个时候外面是亮的还是黑的? 陈冬:亮的,如果真要是黑天的话,可能更不好判断。 神舟二十号是陈冬执行的第三次飞行任务。当时在返回舱内的还有首次飞天的航天员陈中瑞,他正在固 定他们计划带回地球的物品。 神舟二十号航天员乘组原本按计划应于2025年11月5日返回地球。然而,就在启程前一天对返回舱进行 最终检查确认时,陈冬发现了这处异常。他回忆说,当时是他去检查,用肉眼看的过程中发现舷窗上有 一个三角形的东西。 王杰:我不是很确定,从不同的角度来看的话,给人的感觉是不一样的,很难确定它是一个什么样的形 态,感觉外边有一个裂纹,然后里边也有,但是两边有没有贯穿,这个就很难确定。 记者:你紧张吗? 王杰:我其实不太紧张,因为这个舷窗,最外层是一层防护层,它里边还有两层是压力层,只要压力不 会发生变化,那么我们还是安全的,我也了解咱们航天人,就是不管发生什么事,他们肯定会通过分 析,实验,确定我们能不能返回,影不影响我们的安全,最终才会下结论,所以我并不太担心。 为了看清楚舷窗上究竟是什么,神舟二十号乘组尝试 ...
