NASA is yet to announce a return date for Boeing's troubled Starliner spacecraft, currently docked at the International Space Station (ISS). Astronauts Sunita Williams and Butch Wilmore, who arrived safely earlier this month, are now facing an indefinite stay as NASA and Boeing have delayed their return journey multiple times without scheduling a new date.
The return trip has been postponed three times due to ongoing technical issues, including five helium leaks in the Starliner's thruster system. These leaks, discovered before and after the June 5 launch, have hampered the spacecraft's ability to maneuver, causing it to miss its initial docking window with the ISS. Although a second attempt was successful, allowing the astronauts to board the station, the helium leaks continue to be a concern.
NASA's Commercial Crew Program manager Steve Stich emphasized the importance of taking time to understand and resolve these issues. He stated that the agency is following its standard mission management process, using data to guide decisions regarding the helium leaks and thruster performance observed during docking.
In the meantime, Williams and Wilmore will remain on the ISS until at least July 2, following a scheduled spacewalk. Despite the delays and technical challenges, officials remain hopeful about Starliner's future. Starliner program manager Mark Nappi highlighted the positive feedback from the crew and the importance of learning from this mission to improve future flights.
