NASA said the mysterious pulsing sound was a feedback issue. The Boeing Starliner is scheduled to return to Earth uncrewed on Saturday.
NASA astronaut Butch Wilmore radioed NASA Mission Control reporting that he was hearing a heavy, pulsing sound coming from the Boeing Starliner spaceship.
“There’s a strange noise coming through the speaker”, Williams said in a recording obtained by Ars Technica. “I don’t know what’s making it”, he later added.
