2019年3月29日，宇航员尼克·黑格进行太空行走。他和另一名宇航员克里斯蒂娜·科赫(图外)成功地连接了三块更新、更强大的锂离子电池，取代了之前的六块镍氢电池，这些电池为国际空间站的一对太阳能电池阵列上的一个通道提供电力。新的电池提供了一个更先进、有效的电力能力的运作。

Astronaut Nick Hague performs a spacewalk on March 29, 2019. He and fellow astronaut Christina Koch (out of frame) successfully connected three newer, more powerful lithium-ion batteries to replace the previous six nickel-hydrogen batteries that provide power for one channel on one pair of the International Space Station’s solar arrays. The new batteries provide an improved and more efficient power capacity for operations.
