欧洲空间局（ESA）与美国国家航天局（NASA）宇航员在空间站外完成导航与科学太空行走

ESA, NASA Astronauts Complete Navigation and Science Spacewalk Outside Station

NASA宇航员Jessica Meir与ESA（欧洲空间局）宇航员Sophie Adenot于美国东部时间下午3:29结束了在国际空间站（International Space Station）外的太空行走。

NASA astronaut Jessica Meir and ESA (European Space Agency) astronaut Sophie Adenot concluded their spacewalk outside the International Space Station at 3:29 p.m. EDT.

在这次历时6小时49分钟的太空行走中，Meir和Adenot在空间站Harmony舱的前部端口安装了一个新的反射器，以支持航天器在交会对接操作期间的导航。两人更换了空间站桁架上的一台高清摄像头，并完成了对空间站外部的微生物拭子采样。她们还部分完成了电气系统跳线电缆的安装工作，并开始为未来太空行走中更换阿尔法磁谱仪（Alpha Magnetic Spectrometer）的散热器做准备。

During the 6-hour, 49-minute spacewalk, Meir and Adenot installed a new retroflector on the forward port of the space station’s Harmony module to support spacecraft navigation during rendezvous and docking operations. The duo replaced a high-definition camera on the station’s truss and completed a swab of the space station’s exterior for microorganisms. They also partially completed work to install jumper cables for electrical systems and started work to prepare for the replacement of the Alpha Magnetic Spectrometer’s heat-rejecting radiator on a future spacewalk.

任务控制中心推迟了为该谱仪更换散热器安装剩余导向柱的工作，以便工程师能够制定计划在未来的太空行走中完成这项任务。由于机组人员进度落后于时间表，任务控制团队还将剩余跳线电缆的安装及其他非关键任务推迟到了后续日期。

Mission Control deferred installing the remaining guide studs for the spectrometer’s replacement radiator so engineers can develop a plan to finish the work during a future spacewalk. As the crew fell behind the timeline, the mission control team also shifted completion of the remaining jumper cables and other noncritical tasks to a later date.

在太空行走期间，Adenot的左臂出现了一些活动障碍。Meir检查了Adenot的宇航服，确定是手套加热器线束可能被卡住，导致左肩关节活动受限。在机组人员进入气闸舱之前，解开该关节处的拉链似乎解决了这个问题。

During the spacewalk, Adenot experienced some mobility issues with her left arm. Meir took a look at Adenot’s suit and determined the glove heater harness was likely getting caught and causing limited movement in the left shoulder joint. Unzipping the joint seemed to resolve the issue ahead of the crew entering the airlock.

这是第99次美国太空行走，也是Meir的第七次和Adenot的第三次。Meir目前在NASA女性宇航员太空行走总次数排名中位列第三，仅次于Peggy Whitson（10次）和Suni Williams（9次）。这也是支持空间站组装、维护和升级的第284次太空行走。

U.S. spacewalk 99 was Meir’s seventh and Adenot’s third. Meir now ranks third all-time among woman at NASA for total spacewalks, behind Peggy Whitson (10) and Suni Williams (9). It also was the 284th spacewalk in support of space station assembly, maintenance, and upgrades.

这也是支持空间站组装、维护和升级的第284次太空行走。
