The spacecraft is scheduled to undock from the International Space Station without crew no earlier than Friday.

Key Takeaways:

  • Astronauts aboard Boeing's Starliner spacecraft reported an eerie "sonar-like" noise, which NASA later explained as audio configuration feedback between the spacecraft and the International Space Station.
  • NASA confirmed the noise has ceased and had no technical impact on the crew, Starliner, or station operations, including Starliner's planned uncrewed undocking.
  • Despite the noise being resolved, the Starliner astronauts, Butch Wilmore and Suni Williams, will return to Earth via a SpaceX Dragon spacecraft due to an earlier NASA determination that Starliner posed too much risk for crew return.

NASA on Monday addressed an eerie noise heard aboard Boeing’s Starliner spacecraft by astronaut Butch Wilmore, who along with astronaut Suni Williams arrived at the International Space Station (ISS) in June during Starliner’s inaugural crew flight test (CFT).

The spacecraft is scheduled to autonomously undock from the ISS no earlier than Friday, making way for a SpaceX Dragon spacecraft carrying NASA’s two-person Crew-9 astronaut rotation mission. Wilmore and Williams will hitch a ride home on that Dragon, rather than Starliner, after NASA determined the beleaguered Boeing spacecraft poses too much risk to return with crew as planned.
