NASA astronauts Butch Wilmore and Suni Williams, who launched aboard Boeing’s Starliner spacecraft to the International Space Station (ISS) in June, have reported a repetitive ‘pulsing sound’ coming from the spacecraft, NASA confirmed on Monday.
The two astronauts contacted NASA’s ground crew on Saturday seeking assistance with the unusual sound, according to audio recordings between the astronauts and Mission Control in Houston.
