宇航员克里斯蒂娜·科赫在太空真空中工作

NASA astronaut Christina Koch worked while tethered near the Port 6 truss segment of the International Space Station to replace older hydrogen-nickel batteries with newer, more powerful lithium-ion batteries, during the October 11, 2019, spacewalk. Fellow NASA astronaut Andrew Morgan (out of frame) assisted Koch during the six-hour and 45-minute spacewalk.

On Friday, October 18, 2019, Koch and fellow astronaut Jessica Meir will conduct the first all female spacewalk. They will replace a faulty battery charge/discharge unit (BCDU). The BCDU failed to activate following the installation of new lithium-ion batteries on the space station’s truss earlier this month.

在2019年10月11日的太空行走期间,宇航员克里斯蒂娜·科赫(Christina Koch)在国际空间站的6号端口桁架附近工作,用更新、更强大的锂离子电池取代旧的氢镍电池。美国国家航空航天局宇航员安德鲁·摩根(不在画面中)在6小时45分钟的太空行走中协助科赫。

2019年10月18日星期五,科赫和他的同事杰西卡·梅尔将进行首次女性太空行走。他们将更换有故障的电池充放电单元(BCDU)。本月早些时候,在空间站的桁架上安装了新的锂离子电池后,BCDU未能启动。
