Incredible Discovery Shuttle Footage
Discovery (OV-103), the third of NASA's fleet of reusable, winged spaceships, arrived at Kennedy Space Center in November 1983. It was launched on its first mission, flight 41-D, on August 30, 1984. It carried aloft three communications satellites for deployment by its astronaut crew. Other Discovery milestones include the deployment of the Hubble Space Telescope on mission STS-31 in April 1990, the launching of the Ulysses spacecraft to explore the sun's polar regions on mission STS-41 in October of that year and the deployment of the Upper Atmosphere Research Satellite (UARS) in September 1991. Discovery is named for two famous sailing ships; one sailed by Henry Hudson in 1610-11 to search for a northwest passage between the Atlantic and Pacific Oceans, and the other by James Cook on a voyage during which he discovered the Hawaiian Islands.
