Now there’s a creepy, sonar-like sound coming through one of Starliner’s speakers

Starliner is scheduled to undock from the Worldwide Area Station and make its return trip to Earth uncrewed in only a matter of days, however it apparently nonetheless has a couple of new mysteries left in it to throw on the staff earlier than it departs. On Saturday, astronaut Butch Wilmore alerted NASA’s Mission Management about an unexplained “unusual noise” coming from a speaker within the spacecraft, which you’ll hear in an audio clip of the dialog shared on a NASASpaceflight discussion board by meteorologist Rob Dale (noticed by Ars Technica). It begins at across the 45-second mark, ringing out on a gentle beat. “I don’t know what’s making it,” Wilmore stated.

After confirming they might hear the sound too, as soon as Wilmore introduced his mic over to the speaker, the flight controller in Houston stated, “It was form of like a pulsing noise, nearly like a sonar ping.” Wilmore then lets it play for about 20 seconds extra earlier than wrapping up the decision. “Simply to verify I’m on the identical web page, that is emanating from the speaker in Starliner,” Mission Management requested, “you don’t discover the rest, some other noises, any bizarre configs in there?” The astronaut notes that every little thing else appears regular.

It’s nonetheless unclear what brought about the sound. The Boeing spacecraft has been docked with the ISS since early June, and engineers have since had their arms full making an attempt to resolve the problems that arose throughout its first crewed flight. When Starliner lastly heads again to Earth on September 6, it’ll be leaving its crew — Wilmore and NASA astronaut Suni Williams — behind on the ISS, the place they’ll proceed to work for the following few months whereas they await a ride home from SpaceX in February 2025.
