空间站最后一块卷轴式太阳能电池阵展开：发电能力升至约215千瓦
美国国家航空航天局（NASA）宇航员阿尼尔·梅农与加拿大航天局宇航员约书亚·库特里克11月5日完成一次太空行走，于美东时间下午3时35分结束出舱，在国际空间站3B通道上安装并展开第八块、也是最后一块卷轴式太阳能电池阵（IROSA），空间站的电力增容升级就此全部完成。这次出舱历时6小时59分钟。
空间站的电力增容工作始于2021年2月，此后宇航员共完成18次太空行走来准备电力通道设备并安装这八块电池阵。八块卷轴式电池阵全部就位后，空间站的发电能力从160千瓦提升至约215千瓦，为站上的科学实验与关键系统、乃至空间站寿命末期的安全受控离轨提供电力保障。
这次出舱是美国第101次太空行走，也是支持空间站组装、维护与升级的第286次太空行走；梅农累计完成5次太空行走，库特里克完成2次。（来源：美国国家航空航天局）
Final Roll-Out Solar Array Deployed on Space Station: Power Capacity Rises to About 215 Kilowatts
NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk completed a spacewalk outside the International Space Station on November 5, concluding at 3:35 p.m. EST after six hours and 59 minutes. During the walk they installed and deployed the eighth and final International Space Station Roll-Out Solar Array (IROSA) on the station's 3B channel, completing the station's power augmentation upgrades.
Work to augment the station's power generation began in February 2021, and astronauts have since completed 18 spacewalks to prepare power channel equipment and install the eight arrays. Together, the roll-out arrays increase the station's power generation capacity from 160 kilowatts to approximately 215 kilowatts, supporting critical station operations including its safe and controlled deorbit at the end of its life.
U.S. spacewalk 101 was Menon's fifth and Kutryk's second, and it was the 286th spacewalk in support of space station assembly, maintenance and upgrades. (Source: NASA)
