宇航员的工作场景

On June 26, 2020, spacewalkers Bob Behnken and Chris Cassidy completed the first of two scheduled spacewalks to replace batteries on one of two power channels on the far starboard truss (S6 Truss) of the International Space Station.

In this image posted by @AstroBehnken on Twitter, he said: “Yesterday, @Astro_SEAL snapped this shot from our worksite on @Space_Station – @SpaceX ’s Crew Dragon and @JAXA_en ’s HTV in clear view. Not bad for a view while working …”

During the spacewalk, Behnken and Cassidy removed five of six aging nickel-hydrogen batteries for one of two power channels for the starboard 6 (S6) truss, installed two of three new lithium-ion batteries, and installed two of three associated adapter plates that are used to complete the power circuit to the new batteries. Mission control reports that the two new batteries are working.

Cassidy and Behnken are scheduled to complete the upgrade to this initial power channel in a second spacewalk on July 1.

2020年6月26日，太空行走者鲍勃·本肯(Bob Behnken)和克里斯·卡西迪(Chris Cassidy)完成了两次太空行走中的第一次，更换了国际空间站远右板桁架(S6桁架)上两个电源通道之一的电池。

在这张由@AstroBehnken发布在推特上的照片中，他说:“昨天，@Astro_SEAL在@Space_Station上从我们的工作场所——@SpaceX的Dragon和@JAXA_en的HTV上清晰地抓拍到了这张照片。工作时看风景还不错……”

在进行太空行走时，本肯和卡西迪为右舷6号(S6)桁架的两个电源通道之一拆卸了六个老化的镍氢电池中的五个，安装了三个新的锂离子电池中的两个，并安装了三个相关联的适配器板中的两个，这些适配器板用于完成新电池的电源电路。任务控制中心报告说，两台新电池工作正常。

卡西迪和本肯计划在7月1日的第二次太空行走中完成对这条初始电源通道的升级。
