This mission has proven how much skill it takes to be an astronaut. These professionals are in a place where they can’t just drive to the store to pick up some extra parts. When something goes wrong or breaks, as in the solar panel that happened on this mission, they have to work with what is around them. It is a remarkable example of planning for everything.
