Space Shuttle Discovery
Discovery has earned a place of honor in the collection of national treasures preserved by the National Air and Space Museum. 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 has a record of distinctions. Discovery well represents the full scope of human spaceflight in the period 1981-2011.
