Strange sound heard from inside Sunita Williams's Starliner

In what appears like mounting troubles for the stranded Nasa astronauts Sunita Williams and Butch Wilmore, the astronaut duo has reported hearing "strange noises" emanating from the faulty Starliner capsule.

This development surfaces just days ahead of the scheduled departure of the uncrewed Starliner from the station for its return to Earth. According to a Fox News report, the audio captures a rhythmic, pulsating sound occurring at regular intervals.

With a considerable journey ahead before reaching Earth, the seasoned astronauts, currently aboard the International Space Station (ISS), have described the noise as a "pulsing noise, almost like a sonar ping," according to a recording first shared by meteorologist Rob Dale.
