A NASA astronaut at the International Space Station (ISS) on Saturday reported hearing a “strange noise” coming from the Boeing Starliner spacecraft just days before it is set to leave the station and return to Earth on autopilot.
The astronaut, Butch Wilmore, radioed Mission Control at Johnson Space Center in Houston to inquire about the noise.
On an audio recording of the exchange, Wilmore holds up a phone to the speakers so that Mission Control could hear the noise he was referring to. A pulsating sound emanating at steady intervals can be heard through Wilmore’s device.
