They will examine current vehicle "with fine tooth comb" maybe extra spacewalks. If need to abandon ship and use ISS as safe harbor, might wait to come back in simple/reliable Russian capsules or launch Atlantis with plenty of extra tiles, leading edge parts so they could repair any problem.
Old hands are now saying again "why didn't we stay with simple, disposable capsule idea, etc." "Why build spaceplane we never used (capabilities of?)
Why would they "need to abandon ship"? You're now just blowing hysteria smoke out your butt. This shuttle arrived in orbit with far less damage than most any of the previous ones.
