E is incorrect because it says 'as it launches'. This means that they are doing tests and repairs as the flight is occurring. Does this make sense? If I am an astronaut, I would pretty upset if my wing fell off while we were taking off. The meaning of the sentence is to convey that they do tests during the down time between flights.
Does this help?
