太空行走者乔什·卡萨达准备展开太阳能电池阵列

Dec. 22, 2022 — Expedition 68 Flight Engineer and NASA spacewalker Josh Cassada prepares a roll-out solar array for its deployment on the International Space Station’s (ISS) Port-4 truss segment as the orbiting lab flew 262 miles above the Atlantic Ocean off the coast of Namibia.

Astronauts Frank Rubio and Josh Cassada conducted a spacewalk on Thursday, Dec. 22, 2022, for seven hours and eight minutes to install the new roll-out solar arrays to upgrade the station’s power system. The new ISS Roll-Out Solar Arrays (iROSAs) will increase power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts.

It was the 257th spacewalk in support of space station assembly, upgrades, and maintenance, and was the third spacewalk for both astronauts.

2022年12月22日，第68号远征队飞行工程师和NASA太空行走者乔什·卡萨达在纳米比亚海岸大西洋上空262英里处的轨道实验室中，准备在国际空间站（ISS）的特拉斯段部署一个展开式太阳能电池阵列。

宇航员弗兰克·卢比奥和乔什·卡萨达于2022年12月22日（星期四）进行了7小时8分钟的太空行走，以安装新的展开式太阳能电池阵列，升级空间站的电力系统。新的国际空间站展开式太阳能阵列（iROSA）将使发电能力提高30%，使空间站的总可用电力从160千瓦增加到215千瓦。

这是支持空间站组装、升级和维护的第257次太空行走，也是两名宇航员的第三次太空行走。
