A good home for a great workhorse

The Smithsonian (more properly, the National Air & Space Museum) got a great donation from NASA, a space shuttle:

Discovery has earned a place of honor in the collection of national treasures preserved by the Smithsonian National Air and Space Museum. Discovery is the champion in the space shuttle fleet, having achieved an especially rich history in its 27-year career. The longest-serving orbiter, Discovery flew 39 times from 1984 through 2011—more missions than any of its sister ships, spending altogether 365 days in space. Discovery also flew every type of mission during the space shuttle era and its record of distinctions well represents the full scope of human spaceflight.

Rico says it's a nice gesture, but what else were they gonna do with it?
