NASA has decided it’s too risky to bring two astronauts back to Earth in Boeing’s troubled new capsule. They’ll have to wait until February for a ride home with SpaceX.
Boeing engineers tested the thrusters and managed to replicate the issue. They found that there issue was caused by a bulging of a Teflon valve.
However they don’t understand the root cause of why the Teflon is bulging.
So Boeing said it’s safe for the astronauts to return on Starliner but they also said that they fixed the thruster issues they had on the previous flight.
Not all NASA is confident that the Starliner is safe enough.
IIRC, the whole thing is a bit of misconception in the popular imagination. It’ll reenter just fine if it manages the right maneuvers. The risk is hitting the ISS on the way out.
