 So really what we're doing is just taking the time to make sure that we have looked under every rock and every stone and just to make sure that there's nothing else that would surprise us. All of Starliner's issues are in its service module under the crew capsule. But the service module is discarded before Starliner re-enters the Earth's atmosphere. Studying its problems in space is the only option. We trust that the tests that we're doing are the ones that we need to do to get the right answers to give us the data that we need to come back.
