本周以太空行走准备和空间运动研究收尾

Week Ends With Spacewalk Preps and Space Exercise Research

第75远征队（Expedition 75）机组人员以准备太空行走结束了本周的工作，此次行走旨在完成国际空间站（International Space Station）上一台高速天线的安装。这些轨道居民还探索了新的空间运动技术，研究了人类呼吸系统，并完成了一次地球（Earth）观测任务。

The Expedition 75 crew wrapped up the work week getting ready for a spacewalk to finish installing a high-speed antenna on the International Space Station. The orbital residents also explored new space exercise techniques, studied the human respiratory system, and completed an Earth observation session.

周五，美国国家航天局（NASA）的飞行工程师Anil Menon和欧洲空间局（European Space Agency，ESA）的Sophie Adenot轮流在Quest气闸舱内整理他们将在周二美国东部时间上午8:35进行的太空行走中所使用的工具。两人配置了用于固定在轨道前哨站上的系绳，检查了装有各种专用工具和零件的工具包，并将它们放置在Quest内以备使用。Adenot还在计算机上使用3D动画软件研究了她的太空行走程序，该软件描绘了她在轨道前哨站外的任务。

On Friday, flight engineers Anil Menon of NASA and Sophie Adenot of ESA (European Space Agency) took turns inside the Quest airlock organizing the tools they will use during a spacewalk scheduled for 8:35 a.m. EDT on Tuesday. The pair configured the tethers they will use to stay secured to the orbital outpost, checked the bags carrying an array of specialized tools and parts, and staged them for readiness inside Quest. Adenot also studied her spacewalking procedures on a computer using 3D animation software that depicts her tasks outside of the orbital outpost.

周二的舱外活动期间，太空行走人员将由飞行工程师Jack Hathaway和空间站（space station）指令长Jessica Meir协助，他们均为NASA宇航员。Hathaway和Meir周五共同研究了Canadarm2机械臂的操作，这些操作对于支持Menon和Adenot在空间站Unity舱段上方的Z1桁架段安装备用空地天线至关重要。

The spacewalkers will be assisted throughout Tuesday’s excursion by flight engineer Jack Hathaway and station commander Jessica Meir, both NASA astronauts. Hathway and Meir joined each other Friday and studied the Canadarm2 robotic arm maneuvers necessary to support Menon and Adenot as they install a spare space-to-ground antenna to the Z1 truss segment above the station’s Unity module.

在周二的太空行走中，Menon将乘坐Canadarm2并取回由Adenot从外部平台释放的备用天线。随后，两人将移动至Z1，安装天线，并进行精确的电气和数据连接，以激活与任务控制中心的高速传输。接下来，Adenot将把从Z1临时存放处取下的故障空地天线交给Menon。他们随后会将旧天线安装在存放备用天线的同一个外部平台上，从而完成更换。如果时间允许，太空行走人员还将更换Harmony舱前端口上的一个后向反射器，这将改善SpaceX Dragon等来访航天器的导航、跟踪和对准数据。

During Tuesday’s spacewalk, Menon will ride the Canadarm2 and retrieve a spare antenna released by Adenot from an external platform. The duo will then translate to Z1, install the antenna, and make the precise electrical and data connections required to activate high‑speed transmissions with mission control. Next, Adenot will hand Menon the failed space-to-ground antenna from its temporary stowage on Z1. They will then install the old antenna on the same external platform that housed the spare finishing the swap. If time allows, the spacewalkers will also replace a retroreflector on the forward port of the Harmony module, which improves navigation, tracking, and alignment data for visiting spacecraft such as the SpaceX Dragon.

Hathaway和Adenot周五还有时间研究先进的锻炼方法，以在微重力环境下生活和工作时保持肌肉和骨骼健康。Hathaway开始了他的轮班，采集了血液样本，作为肌肉刺激实验的一部分进行分析。之后，他在Columbus实验舱内将自己固定好并放松，同时在腿部贴上电极，发送电信号刺激肌肉。Adenot穿着装有电极的EasyMotion-2套装，在Tranquility舱的跑步机上慢跑时触发肌肉收缩。这些研究的结果可能会改善空间运动，并使宇航员在返回地球重力后能够更快地恢复肌肉。

Hathway and Adenot still had time scheduled on Friday to study advanced workout methods to maintain muscle and bone health while living and working in microgravity. Hathaway began his shift collecting his blood sample to be analyzed as part of the Muscle Stimulation experiment. Afterward, he applied electrodes to his legs that sent electrical signals stimulating his muscles as he strapped himself in the Columbus laboratory module and relaxed. Adenot wore the EasyMotion-2 suit packed with electrodes that triggered muscle contractions while she jogged on the Tranquility module’s treadmill. Results from the investigations may enhance space exercise and enable faster muscle recovery after returning to Earth’s gravity.

Menon和Meir在本周结束时的额外时间里专注于硬件维护。Menon在Kibo实验舱工作，从Kibo的气闸舱中取出了一个曾暴露在太空真空环境下的科学载荷。Meir为航天服水箱和液体冷却通风服加注了水，以便为航天服系统提供热调节，并确保宇航员在太空行走期间保持舒适。

Menon and Meir focused on hardware maintenance with their extra time at the end of the week. Menon worked in the Kibo laboratory module and removed a scientific payload from Kibo’s airlock that had been exposed to the vacuum of space. Meir refilled a spacesuit tank and a liquid cooling and ventilation garment with water to provide thermal conditioning to suit systems and keep astronauts comfortable during a spacewalk.

俄罗斯国家航天集团（Roscosmos）飞行工程师Andrey Fedyaev周五开始协助科学家了解失重如何影响呼吸系统，他在颈部佩戴了一个声学传感器，记录了他的快速呼气过程。接下来，他记录了从Nauka、Zvezda和曙光号（Zarya）舱段收集的辐射暴露测量数据。飞行工程师Pyotr Dubrov和Anna Kikina在轮班开始时共同卸载了自动地球观测设备，这些设备在机组人员睡眠期间拍摄了地面地标。随后，Dubrov检查了以太网电缆和网络连接，而Kikina则对存放在空间站俄罗斯舱段各处的实验室硬件进行了清点和拍照。

Roscosmos flight engineer Andrey Fedyaev started Friday helping scientists understand how weightlessness affects the respiratory system by wearing an acoustic sensor around his neck that recorded his rapid exhalation. Next, he documented radiation exposure measurements collected from the Nauka, Zvezda, and Zarya modules. Flight engineers Pyotr Dubrov and Anna Kikina joined each other at the beginning of their shift and uninstalled automated Earth observation gear that photographed landmarks on the ground during the crew’s sleep shift. Dubrov then inspected ethernet cables and network connections while Kikina took inventory and photographed lab hardware stowed throughout the station’s Roscosmos segment.
