SPACE reported that on Friday, NASA astronauts Chris Cassidy and Bob Behnken completed a spacewalk outside the ISS that lasted for 6 hours and 7 minutes. The walk concluded at 1:39 p.m. EDT, after the astronauts successfully “swapped out three aging nickel-hydrogen batteries for two more efficient lithium-ion batteries” in the “first of four excursions to upgrade” the ISS’ solar arrays. Cassidy and Behnken “finished the work so quickly that in their fifth hour, they started get-ahead tasks for their next spacewalk, planned for Wednesday (July 1), which will include another set of battery replacements.”
