Yes this is the real Discovery. It is, in a word, even more amazing in the flesh, so to speak. You simply can't appreciate the scale of this beast until you see it. The fact that it flies, well sort of, is amazing it itself. These shots show some detail of the intricate life savling tile network and how the entire craft contributes to its lift when it returns to the atmosphere.
BTW, you can see these and any of the other photos in a larger scale by clicking the photo and clicking on show image at the photo bucket site.
My one regret is not being able to get inside (for any of these exhibits in fact). There are good reasons why you can't but there are also answers to those problems so hopefully the gods of museum budgets will sort that out eventually.
More from both hangers later.
