In 1962, the USA’s National Academy of Sciences recommends building a large space telescope. In 1977, Congress votes to fund the project and construction of Hubble Space Telescope begins. Construction of Hubble Space Telescope was completed in 1985. The launch of Hubble was delayed due to the 1986 Space Shuttle Challenger disaster. Hubble was launched on the space shuttle on April 25, 1990.
