NASA astronaut Robert Behnken works during the Wednesday, July 1, 2020, six-hour and one-minute spacewalk to swap an aging nickel-hydrogen battery for a new lithium-ion battery on the International Space Station’s Starboard-6 truss structure.

NASA astronauts Chris Cassidy and Behnken concluded their spacewalk at 12:14 p.m. EDT. During the spacewalk, the two NASA astronauts completed half the work to upgrade the batteries that provide power for one channel on one pair of the station’s solar arrays. The new batteries provide an improved and more efficient power capacity for operations.

They successfully moved and connected one new, powerful lithium-ion battery and its adapter place to complete the circuit to the new battery and relocated one aging nickel-hydrogen battery to an external platform for future disposal.

The following day, spacesuit checks were on the schedule for the Expedition 63 crew following a spacewalk to replace aging batteries on the space station. The duo also recharged batteries and refilled water tanks inside their U.S. spacesuits.

美国宇航局宇航员罗伯特·本肯(Robert Behnken)在2020年7月1日(星期三)进行了六个小时又一分钟的太空行走,在国际空间站的Starboard-6桁架结构上将老化的镍氢电池换成新的锂离子电池。

美国东部时间下午12点14分,美国宇航局宇航员克里斯·卡西迪和本肯结束了他们的太空行走。在太空行走中,两名NASA宇航员完成了一半的工作,升级了为空间站一对太阳能电池阵列的一个通道提供电力的电池。新的电池为操作提供了改进和更有效的电力能力。

他们成功地移动并连接了一个新的、强大的锂离子电池及其适配器,以完成与新电池的电路连接,并将一个老化的镍氢电池转移到一个外部平台上,以备将来处置。

第二天,第63号远征队宇航员在太空行走更换空间站老化的电池后,对他们的宇航服进行检查。两人还为美国太空服的电池和箱充电。
