NASA astronauts (from top) Chris Cassidy and Robert Behnken work on U.S. spacesuits inside the International Space Station’s Quest airlock. The two are slated to conduct spacewalks on Friday, June 26, and Wednesday, July 1, to begin the replacement of batteries for one of the power channels on the orbiting laboratory.

The spacewalking astronauts will replace aging nickel-hydrogen batteries for one of two power channels on the far starboard truss (S6 Truss) of the station with new lithium-ion batteries that arrived to the station on a Japanese cargo ship last month. The battery replacement work is the culmination of power upgrade spacewalks that began in January 2017.

美国国家航空航天局的宇航员(顶部)克里斯·卡西迪(Chris Cassidy)和罗伯特·贝肯(Robert Behnken)在国际空间站的探索气舱内研究美国宇航服。他们两人将于6月26日(周五)和7月1日(周三)进行太空行走,以开始为轨道实验室中的一个电源通道更换电池。

太空行走的宇航员将用新的锂离子电池替换空间站远右板桁架(S6桁架)上两个动力通道中的一个老化的镍氢电池,这些电池是上个月由一艘日本货船运至空间站的。更换电池的工作是2017年1月开始的太空行走中能源升级的高潮。
