The Hubble space telescope


The Hubble space telescope was carried into space by a space shuttle in April 1990. it was named after the American astronomer Edwin Hubble. Although not the first space telescope, Hubble is one o9f the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy. The HST is a collaboration between NASA and European Space Agency, and is one of NASA’s great observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
Space telescopes were proposed as early as 1923. Hubble was founded in the 1970’s, with a proposed launch in 1983, but the project wasn’t launched till 1990 due to technical delays, budget problems and the challenger disaster. When launched scientists found that the main mirror had been ground incorrectly severely compromising the telescope’s capabilities However, After a servicing mission in 1993 the telescope was restored to its intended quality.
