Astronauts to remain on ISS as NASA delays Boeing Starliner’s return to Earth after helium leaks

NASA has delayed the Boeing Starliner’s return to Earth, forcing two astronauts to remain aboard the International Space Station with an unspecified return date, as the agency investigates the helium leaks and thruster failures that occurred during the spacecraft’s docking earlier this month, officials said Friday.

NASA astronauts Suni Williams, 58, and Barry “Butch” Wilmore, 61, will return to Earth no earlier than June 26 to give their teams more time to analyze data from Starliner,
