国际空间站周四安装最后一面太阳翼：7小时太空行走完成发电系统升级
国际空间站第75远征队11月3日继续为本周的太空行走做准备：加拿大航天局飞行工程师 Joshua Kutryk 与美国国家航空航天局（NASA）飞行工程师 Anil Menon 当天整理工具、检查安全绳，并复习定于周四（11月5日）美东时间上午8时30分开始的太空行走程序。这将是为空间站发电系统升级而安排的两次太空行走中的第二次、也是最后一次。
这次约7小时的出舱任务将把第八面、也是最后一面展开式太阳能电池翼安装到空间站右舷桁架上。安装完成后，一项始于2021年6月的多年升级工程就此收官，空间站发电能力将由160千瓦提升至约215千瓦。NASA+ 等流媒体平台将从周四美东时间上午7时起对太空行走作连续直播。
NASA 飞行工程师 Jessica Watkins 与 Luke Delaney 同样研习了周四的程序：两人将协助 Kutryk 与 Menon 穿脱舱外航天服、监控出舱过程，并操作 Canadarm2 机械臂。Delaney 当天还在 Destiny 实验舱内穿戴 Bio-Monitor 传感背心与头带踩踏健身车，监测心肺系统在失重环境下的适应情况，为未来登月、火星及更远深空任务的乘员健康措施提供数据。
货物方面，Delaney 与 Menon、Watkins 一起在 SpaceX 的 Dragon 货运飞船内调换载荷：该飞船10月15日对接 Harmony 节点舱，预计11月中旬装载已完成的科学实验与空间站硬件返回地球。空间站站长、俄罗斯航天员 Pyotr Dubrov 当天在俄罗斯舱段安装了对地观测设备，飞行工程师 Sergey Teteryatnikov 与 Anna Kikina 分别完成心电血压监测收尾与 Progress 96 货运飞船的水转运、通风系统检查。

Final Solar Array to Be Installed Thursday on the Space Station: Seven-Hour Spacewalk Completes Power Upgrade
Expedition 75 aboard the International Space Station continued preparations on November 3 for this week's spacewalk: Canadian Space Agency flight engineer Joshua Kutryk and NASA flight engineer Anil Menon organized tools, inspected tethers and reviewed procedures for a spacewalk scheduled to begin at 8:30 a.m. EST on Thursday, November 5. It will be the second and final spacewalk in a series to upgrade the station's power generation system.
During the roughly seven-hour excursion, the pair will install the eighth and final roll-out solar array on the station's starboard truss. The job completes a years-long upgrade that began in June 2021 and raises the station's power generating capacity from 160 kilowatts to about 215 kilowatts. NASA+ and other streaming platforms will begin continuous live coverage at 7 a.m. EST on Thursday.
NASA flight engineers Jessica Watkins and Luke Delaney also studied Thursday's procedures: they will help Kutryk and Menon in and out of their spacesuits, monitor the spacewalkers and operate the Canadarm2 robotic arm. Delaney also pedaled on the Destiny laboratory module's exercise cycle wearing the Bio-Monitor's sensor vest and headband, measuring how the cardiorespiratory system adapts to weightlessness to inform crew health measures for future missions to the Moon, Mars and beyond.
On cargo work, Delaney joined Menon and Watkins in swapping payloads inside a SpaceX Dragon cargo spacecraft that docked to the Harmony module on October 15; Dragon is expected to return to Earth in mid-November packed with completed science experiments and station hardware. In the Roscosmos segment, station commander Pyotr Dubrov installed Earth observation gear, while flight engineers Sergey Teteryatnikov and Anna Kikina completed a 24-hour heart and blood-pressure monitoring session and transferred water from the Progress 96 cargo ship and inspected Zvezda ventilation systems, respectively.
