NASA astronaut reports strange noise from Boeing Starliner at ISS, not a major concern.

NASA astronaut Butch Wilmore reported a strange, sonar-like pulsing noise from the Boeing Starliner spacecraft at the International Space Station (ISS). While the source of the sound remains unclear, it is not considered a major concern. Starliner, facing past issues including thruster failures, is scheduled for an autonomous return to Earth on September 6. Wilmore and astronaut Suni Williams will return to Earth in February 2025 aboard a SpaceX spacecraft.
