来源：央视新闻客户端 神舟二十号舷窗异常情况出现后，2025年11月10日，中国载人航天工程总指挥部正式启动应急预案和措 施，决定神舟二十号三名航天员换乘神舟二十一号飞船返回地球，并同步启动神舟二十二号飞船的16天 应急发射任务。 确定换乘神舟二十一飞船后，乘组还面临一项重大变化，神舟二十号飞船返程是5圈返回的方式，而神 舟二十一号飞船采用的是"3圈自主快速返回"方案，这项原计划在2026年神舟二十一号乘组返回时才实 施的关键技术，因这次应急任务提前启用。 记者：你们要重新学习一下吗？ 陈冬：程序发生了变化，需要我们去重新学习。因为5圈的正常返回跟3圈的返回，缩短了3个小时。缩 短3个小时，落实到具体的是流程发生了一些变化，我们需要重新去梳理，这个也是在我们准备的项目 里面的。地面跟我们进行讲解，我们乘组也进行了两次推演。 2025年11月14日，告别的时刻终究还是到来了。 记者：你们等于走了两次，本来要走没走成，后来真走了，怎么和下一个乘组告别？ 陈冬：真走的时候，就会感觉不舍，因为一旦离开又是好几年，也不知道会是多少时间。 其实也没有把空间站当成一个铁疙瘩，就是当成我们朝夕相处的朋友，和我们并肩战斗。 陈 ...
