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.
