保护地球，探索宇宙，发现文明
国际空间站是美国国家航空航天局（NASA）阿尔特弥斯（Artemis）计划的基石，该计划将在2024年前将第一位女性和下一位男性登上月球。作为对微重力环境中生存如何影响生物体（尤其是人类）进行长期研究，以及测试使人类得以月球上工作的技术的唯一场所，空间站是在月球上建立可持续存在的一项独特资产。 登月任务将包括在“门户”（Gateway）月球空间站上、在月球表面以及包括“猎户座”(Orion)飞船和人类着陆系统在内的多个航天器上的时间组合。探索月球的技能和技术将有助于建立未来火星任务所需的能力。国际空间站这个轨道实验室为通向月球和火星所做的贡献如下所示。 人的因素 使宇航员在太空中保持安全是月球任务的重中之重，这需要对微重力环境下生活如何影响人类有广泛的了解。国际空间站提供了近20年的人类研究机会，这是其他平台无...
This image of star trails was compiled from time-lapse photography taken by NASA astronaut Christina Koch from aboard the International Space Station, taken in July 2019. This composite image was made from more than 400 individual photos taken over a span of about 11 minutes as the station traveled from Namibia toward the Red Sea. The image includes many nat...

2019 October 19 All Female Spacewalk Repairs Space Station Image Credit: NASA TV, Expedition 61 Explanation: The failed unit was beyond the reach of the robotic Canadarm2. Therefore, this repair of the International Space Station would require humans. The humans on duty were NASA’s Jessica Meir and Christina Koch. This was the fourth spacewalk for Koch...
来源：NASA TV 北京时间10月18日19时50分，NASA宇航员Christina H Koch和Jessica Meir开始执行空间站首次全女性宇航员太空行走，时长6.5小时，以更换失效的电源控制器。 值得一提的是，Christina Koch和Anne McClain原计划于今年三月执行首次全女宇航员的太空行走，但由于宇航服的尺寸大小不合适，从而放弃了。 来源：NASA video 这段视频回顾了35年前的女宇航员首次太空行走, 1984年,俄罗斯宇航员Svetlana Savitskaya进行了首次太空行走。同年10月，NASA女宇航员Kathy Sullivan进行了太空行走，从此以后，12名美国女宇航员共完成了40次太空行走，这次的太空行走是Christina H Koch第四次太空行走任务，对...
NASA astronaut Christina Koch worked while tethered near the Port 6 truss segment of the International Space Station to replace older hydrogen-nickel batteries with newer, more powerful lithium-ion batteries, during the October 11, 2019, spacewalk. Fellow NASA astronaut Andrew Morgan (out of frame) assisted Koch during the six-hour and 45-minute spacewalk. O...
