航天员"改签"回地球 神二十返回舱玻璃裂纹是个三角形 专家：神二十返回舱玻璃裂纹为不足1毫米空间碎片撞击导致 按照指令，神舟二十号航天员在不同的角度、不同的光线下对异常位置进行拍照，同时利用空间站机械 臂上的摄像机从舱外对舷窗进行辅助拍照。照片传回地面，地面组织了国内十多个玻璃相关行业的专家 对损伤情况进行研判。 近年来，空间碎片数量呈现激增态势，对在轨运行的航天器、人造卫星乃至航天员的生命安全构成的威 胁与日俱增。2025年11月5日，因在飞船舷窗上发现裂纹，神舟二十号返回任务被按下紧急暂停键。 中国航天科技集团五院载人飞船系统总设计师 贾世锦： 这次的裂纹，我们初步判断空间碎片的尺寸应 该不到1毫米，但是因为它的速度太快了。整个裂纹尺寸十几毫米，我们看一角，感觉像是被击穿的样 子，但是毕竟在轨没有办法亲眼去看，可能等神舟二十号飞船回来之后，我们再仔细观察。 永远"空缺"的神舟二十二号乘组 特殊意义在哪儿？ 2025年11月5日，神舟二十号返回任务被按下紧急暂停键。在计划返回前一天对飞船返回舱的例行检 查中，神舟二十号航天员乘组发现舷窗的边缘有一个局部的异常现象。中国航天科技集团五院载人飞船 系统总设计师贾 ...

来源：央视新闻 2025年11月5日，因在飞船舷窗上发现裂纹，神舟二十号返回任务被按下紧急暂停键。经过20多天的高 效应对，随着神舟二十二号飞船返回舱舱门顺利打开，一场牵动无数人心弦的"太空应急大考"画上了圆 满的句号。此次发射的神舟二十二号飞船，除了装载航天食品、新鲜果蔬，还上行了针对神舟二十号飞 船舷窗裂纹的处置装置。业内人士指出，最后神舟二十号会以无人的状态返回地球，返回的过程也会拿 到最真实的试验数据，这个数据对后续相关工作也是非常宝贵、非常有意义的。 随着神舟二十二号应急发射，后续飞船的研制节奏已全面提速。原定明年三月出厂的神舟二十三号飞 船，预计将提前两个月完工；神舟二十四号飞船也瞄准明年夏季的出厂目标，全力推进。由于航天员乘 组编号通常与所执行的飞船任务编号一致，下一个乘组将被命名为"神舟二十三号航天员乘组"，这意味 着"神舟二十二号航天员乘组"在序列中永远空缺。 ...

Core Insights - The Shenzhou-20 mission was temporarily halted due to a crack found in the spacecraft's window, leading to an emergency response that culminated in the successful return of the Shenzhou-22 spacecraft, which carried supplies and a device to address the crack issue [1][2]. Group 1: Mission Response - The Shenzhou-22 spacecraft was launched with a device to handle the crack in the Shenzhou-20 window, demonstrating a proactive approach to mission challenges [1][2]. - The Shenzhou-20 will return to Earth unmanned, providing valuable data for future missions [2]. Group 2: Space Debris Concerns - The increase in space debris poses significant threats to operational spacecraft and astronauts, necessitating enhanced protective measures within China's space program [6]. - The crack in the Shenzhou-20 window was preliminarily attributed to a piece of space debris less than 1 millimeter in size, highlighting the dangers posed by high-speed debris [5]. Group 3: Future Developments - The Shenzhou-23 spacecraft's production has been accelerated, with completion expected two months earlier than originally planned, while the Shenzhou-24 is targeted for summer production [7]. - The absence of a crew for the Shenzhou-22 mission serves as a reminder for continuous improvement and vigilance in the space program, emphasizing that achieving perfection is an ongoing pursuit [9].

Core Points - China is set to launch its new generation crewed spacecraft "Dream Boat" in 2026, with the first flight taking place at the Wenchang Space Launch Site using the Long March 10A rocket [1] - The 2026 mission will include four flight tasks: Tianzhou-10, Shenzhou-22, Shenzhou-23, and Dream Boat-1, focusing on various space operations [1] - The Dream Boat spacecraft is an upgraded version of the Shenzhou spacecraft, featuring a modular design consisting of a return capsule and a service module for transportation to and from the space station [1] Mission Details - The Tianzhou-10 cargo spacecraft will be responsible for transporting supplies for astronauts, including extravehicular suits, maintenance parts, propellants, and various payloads for application tasks, while also managing the disposal of waste in orbit [2] - The Shenzhou-22 and Shenzhou-23 missions will involve extravehicular activities by astronauts, cargo airlock operations, and continued space science experiments and technology tests [1] - Notably, one astronaut from the Shenzhou-22 crew will participate in a long-term stay experiment lasting over one year [1]
