Two NASA astronauts are facing an extended stay at the International Space Station due to issues with their Boeing capsule. Originally scheduled to return in mid-June after a week-long visit, Butch Wilmore and Suni Williams will remain in space until engineers resolve problems with the Starliner capsule.
The decision to delay their return was made after thruster failures and helium leaks were discovered on the capsule. Mission managers, including NASA's commercial crew program manager, Steve Stich, have not yet determined a new return date for the astronauts.
