We attended the special day at the Udvar-Hazy Smithsonian Air & Space Museum yesterday for when they pulled out the Enterprise shuttle and brought in the Discovery Shuttle. Lots of fanfare, speeches, and fun for the family. Discovery looked amazing with its space dust and burn marks all over it from its 39 missions. Talked with a NASA employee as Discovery was being tugged in, she said the rust looking marks on the sides are from damage done by "atomic oxygen" which vehicles get exposed to in space. Enterprise is still bright white in color because it was built as a spare shuttle and has never flown in space. The two shuttle were parked nose-to-nose for a photo opportunity for only about 3 hours yesterday. Enterprise will get loaded onto the 747 and will go to New York City. Here are some pictures.
