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.
