Space Telescope Research Paper
1.0 Introduction
The Hubble Space Telescope was created by and named after astronomer Edwin P. Hubble. He was known for his creation of Hubble’s Law which is used to calculate the rate at which the universe is expanding. He is also known for his discovery of the galaxies that are outside the Milky Way. The Hubble Space Telescope is a large telescope that is placed in orbit around the earth. Scientists have figured out that by placing a telescope in space, putting it outside of earth’s atmosphere, a telescope can escape any atmospheric disturbances that hinder the quality of the pictures that taken. Since the Hubble became operational in 1990 it is well known because of the discoveries that it has contributed to astronomy. The Hubble is …show more content…
The reason behind the Hubble’s success is that not only is it in space to escape the earth’s atmosphere but also because of a system called the Optical Telescope Assembly. This assembly of mirrors essentially redirects incoming light down a tube with baffles which are used to keep stray light out, and the light eventually hits a series of mirrors that lead to the onboard scientific instruments that piece together the picture. The mirrors used in the Hubble are made out of an ultra low expansion glass and is coated with a layer of pure aluminum and magnesium fluoride that help to give a more reflective surface all these are done to prevent the mirror from warping. One part of the telescope that has since been replaced is part of the optical telescope assembly called the Corrective Optics Space Telescope Axial Replacement (COSTAR). What the scientist first discovered was that there was a flaw in their primary mirror called spherical aberration and this caused a fuzzy image to be produced. To correct this problem the scientist created a corrective lens much like eyeglasses for a human to restore the Hubble’s vision. This was where COSTAR came into place where it was installed during servicing missions in order to fix the flaws on Hubble. However the COSTAR was removed when the new Advanced Camera was sent to replace
