The spacewalk is began at 11:31 UTC April 8, 2019.
Some of the activities performed during the spacewalk included running cables and relocating a battery adapter plate to facilitate the replacement of a failed lithium-ion battery with two old nickel-hydrogen units. A replacement lithium-ion unit is expected to be orbited by a future cargo ship.
