Boeing Struggles to Resolve Starliner Thruster Issues, Delaying Astronauts' Return

NASA and Boeing engineers continue to analyze data from ground tests to ensure the spacecraft's safe return from the ISS.

Starliner has been docked at the ISS since June 6 due to thruster failures and helium leaks.
Astronauts Butch Wilmore and Suni Williams remain on the ISS, awaiting clearance for their return.
Recent ground tests replicated inflight conditions to understand the thruster malfunctions.
NASA confirms that Starliner can safely return in an emergency, but thorough checks are ongoing.
The spacecraft's return date is still undetermined as engineers dissect test results.
