NASA astronaut Butch Wilmore reported hearing an unusual, sonar-like pulsing noise from the Boeing Starliner spacecraft, which is currently docked at the International Space Station (ISS). The sound was captured and relayed to Mission Control, who confirmed its existence and indicated they would investigate further. This incident occurs as the Starliner is set to return to Earth autonomously on September 6, after Wilmore and fellow astronaut Sunita Williams were unable to return as originally planned due to multiple technical issues. The Starliner has faced significant setbacks, including thruster failures and helium leaks, prompting NASA to opt for SpaceX’s Crew Dragon for future crew returns. Wilmore's inquiry about the strange noise has drawn attention to the ongoing challenges faced by Boeing’s Starliner program, which has been plagued by delays and cost overruns. The situation continues to unfold as NASA works to decipher the cause of the noise and ensure the safety of future missions.
