1. Introduction The Hubble Space telescope has been Orbiting the Earth for over two decades, Hubble has helped to answer some of the most compelling astronomical questions of our time – and uncovered mysteries we never knew existed. Investigating everything from black holes to planets around other stars, Hubble has changed the face of astronomy, ushering in a new chapter of humanity’s exploration of the universe. Although named to honor astronomer Edwin Hubble, the telescope was championed by astronomer Lyman Spitzer. Launched in April of 1990 and poised for many more years of trailblazing science ranging from our own solar system to the edge of the observable universe, NASA’s Hubble Space Telescope is fulfilling the hopes astronomers…show more content…
As most of the ultraviolet radiations are blocked by the Ozone layer, so it was very difficult to study ultraviolet radiations from earth’s surface. In order to better understand the Ultraviolet radiation an observatory was created and sent beyond the Earth’s atmosphere. IUE was the first telescope that used Ultraviolet technology. Its purpose was to explore astronomical objects such as galaxies, comets, asteroids, and stars. It weighed 1,420 lbs. and measured 14 feet by 5 feet by 5 feet. It surveyed the sky for 18 years using 45 cm aperture telescope and two spectrographs. The major success of IUE mission was the identification of exploding star supernova 178A and comet Hyakutake as it underwent chemical changes for five days. Originally, IUE was made to last for five years but it lasted for nineteen years. It also received U.S Presidential Award for design Excellence. 3. NASA’s Early Space Programs The evolution of Spitzer Space Telescope started with the development of infrared technology. Just like Gamma ray, X- ray, radio, and UV ray technologies, infrared was another huge step towards the new achievements of space. The idea of infrared telescopes (Ref 9) developed during 1960’s when scientists started attaching huge balloons with telescopes to take them to the lower atmosphere of Earth. Later, in 1970’s
