The 10 day-work also included installation of several instruments and some other equipment . The first mission was coded STS 61 Endeavor .

The mission was considered the most manifold black market of task since the launch of the Hubble Space Telescope . It consists ofReplacing the High Speed Photometer with the COSTAR corrective optics package and toReplacing the WFPC with WFPC2 with intern! al opthalmic chastisement systemReplacing the solar arrays and their drive electronicsReplacing four of the gyroscopes used in telescope pointing system , two electrical control units , two magnetometers and other electrical componentsUpgrading the onboard computers and boosted telescope s orbit (this is necessary collectable to the orbital decaying phenomena (Brandt , 1994After the first servicing mission was accomplished researchers witnessed a great enhancement in the Telescopes capability of capturing spatial images . resultant servicing missions...If you want to get a full essay, place it on our website: BestEssayCheap.com
