Hubble Telescope

Conceived in the 1940’s, designed in the 1970’s, built in the 1980’s, it was in April of 1990 that the Hubble telescope was placed into orbit by the crew of the space shuttle Discovery. A major problem during its design was that the lenses were incorrectly calculated, so the first images were blurry. A repair mission three years later basically outfitted Hubble with glasses.
