The Hubble Space Telescope becomes operational. The Hubble Telescope, built under the supervision of the U.S. National Aeronautics and Space Administration (NASA), is placed into orbit above the Earth's obscuring atmosphere. After an optical flaw is corrected, Hubble examines the universe at high resolution in wave lengths from the ultra-violet to the infrared.
