CAPE CANAVERAL, Fla.—A pair of spacewalking astronauts tackled the final set of battery swaps outside the International Space Station on Thursday.

NASA’s Bob Behnken and Chris Cassidy ventured out on their third spacewalk over the past few weeks. They needed to remove six more old batteries in the space station’s power grid, and replace them with new, improved ones.
