 Finally, they did launch and two more problems popped up. First, there were several leaks in a helium system that is part of the system that allows the spacecraft to maneuver. And then there were separate problems with the thrusters, which are also used to return to Earth. Now, Boeing says this is a test flight. They say none of this prevents this spacecraft from going back if it needs to. But NASA has stayed very quiet about the whole thing. They haven't said anything publicly since a week ago.
