We just gotta hope that thing ,with so many critical elements, works as designed. We can't build a circuit board and go fix it.
I don't know how far it is from getting all of its bits and pieces set to go to work. The people who have spent the last years of their lives working on it are probably not sleeping well. I hope it makes them all cheer!
