NASA astronauts Butch Wilmore and Sunita Williams have reported a 'strange noise' resembling a sonar ping from the Boeing Starliner aboard the International Space Station (ISS). Wilmore contacted Mission Control to investigate the sound, which was described as a pulsing noise coming from the spacecraft's speakers. This incident adds to the ongoing issues faced by the Starliner, which had previously encountered helium leaks and thruster failures, leading to an extended stay for the astronauts since June. NASA has decided that it is too risky to return Wilmore and Williams on the problematic Starliner; instead, they will return home on a SpaceX Crew Dragon capsule in 2025. While the source of the noise is still undetermined, experts emphasize the importance of investigating it thoroughly, as it could indicate underlying issues with the spacecraft's systems. The situation has drawn attention, raising questions about the safety and reliability of the Starliner, which is still in its testing phase after significant investment.
