研究表明，航天员在太空失重环境中容易产生心肺功能减弱、血量减少、下肢肌肉萎缩、骨流失等问题，长期下去会影响航天员的健康和在轨工作能力。太空跑台就是针对这些不利影响而采取的一项防护手段。在神舟十二号任务中，航天员每天运动时间一般不少于两小时。 跑台设计人员余新明告诉记者，太空跑台与人们所见的跑步机外观类似，不同的是，由于太空的微重力环境，跑台要有隔振设计、束缚带和力负荷加载装置等。 对于中...
Spacesuits keep astronauts safe Share CLOSE Screen image taken at Beijing Aerospace Control Center on July 4, 2021, shows Chinese astronaut Liu Boming walking out of the space station core module Tianhe. Chinese astronauts Liu Boming and Tang Hongbo both slipped out of the space station core module Tianhe at 11:02 am (Beijing Time) on July 4, starting extravehicular activities, according to the China Manned Space Agency. [Photo/Xinhua] China's domestically developed spacesuits have ensured the safety of astronauts during their stay in the space station's core Tianhe modu...
Homemade spacesuits ensure safety of Chinese astronauts in space 1 2021-07-08 08:16:37Xinhua Editor : Li Yan ECNS App Download China's self-developed spacesuits have ensured the safety of astronauts during their stay in the space station core module Tianhe and while performing extravehicular activities (EVAs) outside the module. The space gears include intravehicular spacesuits and extravehicular spacesuits, according to different scenarios, said Zhang Wanxin, director of the astronaut suit project under the Astronaut Center of China (ACC). Intravehicular spac...
机器人或自动化技术通常是人类出舱活动的替代方案，但目前设计能执行预期任务之外或超出已知任务参数范围的机器人成本高，且技术尚不成熟，无法完全取代人类。而航天员的出舱活动效率较高，并且对意外故障和突发事件做出响应的能力较强。正如建造摩天大楼需要建筑工人和起重机一样，出舱活动需要航天员和机器人共同完成舱外作业。 美国航天局认为，宇航员在舱外维修卫星或其他航天器，可以避免将它们带回地球修理；在舱外...
“且不说它的承压材料要经过多少轮的选择、测试，光密封加缝合就耗时两个月，一共完成47道工序。”中心研发与总装测试部副部长邓小伟说，就拿面窗除尘来说，先吹洗，再不间断擦拭两小时左右，直到肉眼看不到一丝灰尘。 其中，粘胶要分多轮逐步进行。每次粘胶，都要将其放到恒温恒湿箱里进行胶固化，再进行气密性测试以及低温露点测试，可视区还要进行充分的氮气置换，防止夹层中残留的水汽在低温情况下起雾影响视线。 这一套严密的...
