Discovery was NASA's third space shuttle orbiter to join the fleet, arriving for the first time at the Kennedy Space Center in Florida in November 1983.
Shuttle Discovery was named for several sailing ships used to explore the world. One of those sailing vessels used in the early 1600s by Henry Hudson explored Hudson Bay searching for a northwest passage from the Atlantic to the Pacific.
