NASA astronauts extend their stay at the International Space Station because of delays with Boeing's Starliner.
Reading
Two astronauts will stay longer on the space station because of problems with their ride home. The astronauts were supposed to come back in June, but their Boeing capsule had some issues.
NASA is not sure when the astronauts will be back, but they are working to fix the problems. They might use a SpaceX capsule as a backup plan if needed.
Engineers are looking into the cause of the thruster failures on the Boeing capsule. They believe that bad seals might be the reason for both the thruster and helium leak problems.
The capsule has small thrusters for maneuvering and bigger engines for landing. The parts with the problems will be discarded before landing, so engineers can't study them after the flight.
Boeing was hired by NASA to fly astronauts to the space station after the space shuttles retired. This was Boeing's first crewed test flight, and they have faced several problems in previous tests.
