Discovery retired

Having completed its last mission, Space Shuttle Discovery is retired, stripped of working engine parts and other items, and donated to the Smithsonian Air & Space Museum by NASA. The workhorse of the shuttle fleet, Discovery flew in space 39 times starting in 1984, visiting both Mir and the International Space Station, and racking up a cumulative total of an entire year in orbit. Discovery takes the place of the test orbiter, Enterprise, which has been on display at the Smithsonian since the 1980s.
