Two astronauts aboard the International Space Station (ISS) conducted a spacewalk to continue the process of increasing the Station’s electrical power generation output. U.S. EVA-72 was conducted by NASA astronaut Kate Rubins and Japan Aerospace Exploration Agency astronaut Soichi Noguchi, who officially began the sojourn at 06:37 EST/11:37 UTC.
The spacewalk ended with the major tasks completed but the lesser tasks deferred to a future spacewalk when work at the solar array site took longer than planned and spacesuit battery limits mandated a conclusion to the EVA after 6 hours 56 minutes.
