The Hubble Space Telescope

superior Speed Photometer were replaced by COSTARCorrective Optics Space telescope Axial (COSTARCostar was a system designed to correct the world(a) aberration for light focused at the FOC , FOC and GHRS . The system consisted of twain mirrors in the light path , one of which would be judge o correct the aberrationFine Guidance Sensors (FGSThe FGS are accompanimental scientific instruments laid within the Hubble Space telescope . Their function is to keep on accuracy during an observation . all the same , they can also be used for an extremely accurate astrometry with measurements accurate to within 10 .0003 arcsecond (Burrows , 1991Previous and Future Service Missions of the TelescopeAccording to the designers of the telescope , the device has ceaselessly been designed so that it can be regularly serviced . However , the problem with flawed mirror brought a much greater importance to the offset servicing mission . In addition of the scheduled servicing activities , the astronauts would have to carry out big work n the telescope to install corrective optics . The 10 day-work also included installation of several instruments and other equipment . The first mission was coded STS 61 Endeavor .

The mission was considered the most confused range 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 internal ocular correction systemReplacing the solar arrays and their drive electronicsReplacing four of the gyroscopes used in telescope pointing system , dickens electrical control units , two magnetometers and other electrical componentsUpgrading the onboard computers and boosted telescope s orbit (this is necessary due(p) 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 . subsequent servicing missions...If you want to get a full essay, tramp it on our website: Ordercustompaper.com
