央视网消息：此次神舟二十号、神舟十九号两个乘组在空间站天和核心舱完成在轨交接，是"神舟家族"第六次在太空传递"接力棒"。 27日下午，神舟二十号指令长陈冬从神舟十九号指令长蔡旭哲手中接过了空间站的钥匙，完成了中国空间站第6次在轨交接轮换。巧合的 是，这把空间站钥匙最初就是由陈冬传递出去的。 神舟十四号航天员陈冬称："我们即将完成神舟十四号任务，现在我将空间站钥匙交给你们，预祝你们圆满完成后续任务。" 神舟十五号航天员费俊龙称："谢谢你们，我代表神舟十五号，感谢你们前期为我们打下良好的基础，我们一定圆满完成神舟十五号飞行 任务。" 2022年12月2日晚，当时还是神舟十四号指令长的航天员陈冬，将空间站钥匙郑重交到神十五指令长费俊龙手上，这是中国空间站首次完 成两个乘组的有人交接轮换，标志着中国空间站正式开启长期有人驻留的时代。 首次在轨交接，第一、第二批航天员还是当时空间站阶段的主力；到了2023年第2、第3次在轨交接的时候，则是三批航天员"三代同堂"； 2024年第4次在轨交接，第二、第三批航天员已成为空间站应用与发展阶段的主力。半年后，第5次在轨交接，两名第三批的"90后"航天员也加 入了这场太空接力赛。 ...
