2026年10月30日，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乔舒亚·库特里克共同执行了一次历时7小时11分钟的太空行走，任务于东部夏令时间下午3:08结束 1。此次作业在国际空间站的2A电力通道上成功安装了第七个卷展式太阳能阵列（IROSA）1。该次任务被指定为美国进行的第100次太空行走，也是支持国际空间站组装和维护的第285次太空行走 1。
计划在11月5日进行的下一次太空行走中，将在3B电力通道安装第八个也是最后一个新阵列 1。全部八个新阵列安装完成后，空间站的可用电力将从160千瓦增加到约215千瓦，提升幅度达30% 1。这一电力升级旨在支持空间站的关键运行及最终的受控离轨 1。
NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk completed a spacewalk lasting 7 hours and 11 minutes to install the seventh International Space Station Roll-Out Solar Array (IROSA). 1 The operation, which concluded at 3:08 p.m. EDT on October 30, placed the new array at the station's 2A power channel. 1 This milestone marked the 100th U.S. spacewalk and the 285th walk dedicated to supporting the assembly and maintenance of the orbital laboratory. 1
The installation is a precursor to the final phase of the solar upgrade, scheduled for a spacewalk on November 5 that will see the eighth and last array deployed at the 3B power channel. 1 Once all eight new arrays are fully operational, they will increase the station's available electrical power from 160 kilowatts to approximately 215 kilowatts, representing a 30% boost. 1 This enhanced capacity is essential for sustaining critical operations and facilitating the station's eventual controlled deorbit. 1
