2025年8月1日，在美国佛罗里达州肯尼迪航天中心，搭乘"龙"飞船前往空间站的4名宇航员与媒体见 面。 2025年8月1日，"龙"飞船搭乘"猎鹰9"火箭从美国佛罗里达州肯尼迪航天中心发射升空。 在地球上，人们患病可前往医院就诊。离开地球、进入浩瀚太空的宇航员，若出现健康问题，又该如何 应对？ 由于一名宇航员身体抱恙，在国际空间站执行任务的一个4人宇航员团队搭乘美国太空探索技术公司 的"龙"飞船，于1月15日提前返回地球。这是国际空间站自2000年11月开始接待轮换宇航员乘组以来的 首次医疗撤离事件。 太空紧急事件已非首次发生 1 所有宇航员都要接受专业医学训练 美航天局首席健康和医疗官詹姆斯·波尔克日前在新闻发布会上指出，在国际空间站运行的25年里，美 航天局处理了一系列与宇航员健康有关的情况。宇航员配备了相应设备、药品及所需物资，使他们得以 在太空被诊断或治疗。 在进入国际空间站之前，所有宇航员都要接受专业的医学训练，以便在紧急情况下进行一些基础医疗操 作，比如缝合伤口、拔牙、打针以及读取超声图像等。若出现宇航员未曾接受相关训练、无法应对的情 况，就需要向地球上的医生"呼救"。宇航员可以就超声图像等与地面团 ...

据中国载人航天工程办公室消息，今天9点34分，神舟二十号飞船返回舱在东风着陆场成功着陆。经现场检查确认，神舟二十号飞船返回舱外观总体正 常，舱内下行物品状态良好，神舟二十号飞船返回任务取得圆满成功。 中国航天科技集团邵立民：目前看来应该都是符合预期的，我们其实更关注的是后续舷窗怎么改进。我们想在舷窗结构上加强，它必须能硬扛空间碎片。 后续可能还要进一步加强更微小的空间碎片的监视，大碎片、中等碎片主要就是靠躲避，小碎片主要靠飞船本身舷窗结构的强度，后续会改进。 飞船为何必须有"窗"？ 有人可能好奇，舷窗这么易碎，如果飞船上不安装窗户，是不是就可以避免被太空碎片撞击导致紧急情况的发生。其实，飞船的舷窗不仅仅是航天员观察 外界的窗口，更是在紧急情况下保障生命安全的关键设备，是飞船上不可或缺的一部分。 神舟飞船舷窗的首要作用是安全观察。无论是在发射段进行应急逃逸，还是飞船执行应急返回任务，航天员都需要通过舷窗直接观察返回舱外的着陆环 境，判断是否存在风险，因此舷窗必不可少。 直面太空挑战，神舟二十号舷窗舱内加固 在这次返回任务中，大家最关心的就是神舟二十号飞船的舷窗裂纹。航天员在舱内实施了舷窗裂纹处置装置安装，这项任 ...
