1984: The space shuttle Discovery launched from Kennedy Space Center on its first mission (41-D), to deploy three communications satellites. Since that inaugural flight, Discovery flew 149 million miles in 39 missions, completed 5,830 orbits, and spent 365 days in orbit in over 27 years. Discovery flew more flights than any other Orbiter Shuttle. In 1990, Discovery carried the Hubble Space Telescope into space, and provided both the second and third Hubble servicing missions in 1997 and 1999. Discovery was the first orbiter to undergo Orbiter Major Modification (OMM) period at the Kennedy Space Center. On March 9, 2011, Discovery made its final touchdown at Kennedy Space Center.
