Spacesuit battery glitch forces early end to Russian spacewalk

A Russian spacewalk outside the International Space Station ended hours earlier than planned on Wednesday after a cosmonaut discovered an electrical issue with his spacesuit, U.S. and Russian officials said. Oleg Artemyev was roughly two hours into a six-hour spacewalk when voltage levels in his spacesuit's battery began to unexpectedly drop, prompting flight controllers in Moscow to repeatedly order the cosmonaut's immediate return to the space station's airlock.
