Funches 1 Macharia Funches Professor Judkins English 106 10/1/2010 The Telescope Step back for a moment and imagine life as you know it now. For the most part you have clean water, good hospital care, access to a wide variety of goods, and there are no real shortages of recourses. All of these factors are a result of the US’ once mighty and powerful economy. The fact of the matter is that the economy is largely driven by war. “Twenty-five hundred years ago the Chinese general Sun Tzu wrote, "If you know the enemy and know yourself, you need not fear the result of a hundred battles." But how are U.S. soldiers, operating covertly in unfamiliar and hostile territory, to know where their allies are, where their enemies are, and what each is doing? How are they to receive commands and report status? The answer is satellite communications.” A major reason why the US has been so successful in terms of its military experience is because of the enormous amount of intelligence which we are able to funnel into the country through our telescopic spy satellites in space. Our telescopic satellites also give us an advantage in terms of communications with our military personnel. Without these satellites we would be ignorant of our enemy’s actions and be without key communications, leaving the lifestyle that we are accustomed to up to chance.

Funches 2 Military satellites have evolved drastically since their first use in the 1960s. The first satellites were simply used for relaying signals from one part of the world to another. Over time the application of military satellites has changed dramatically. Satellites now have higher bandwidth and power, allowing them to be able to send and retrieve more information to and from variety of sources. Because of the improvement of Satellite electronics satellites are now able zoom in and view other nation’s military activity, allowing the US to always be in the know and as a result to always be prepared. However, the satellite wasn’t the first application of viewing one’s opponent from a distance. It was the telescope which eventually gave rise to the modern telescopic satellite. The oldest clear hint of a telescopic system dates back to Fracastoro in 1538. Although nothing more than a large blurry object could be seen through the first telescopic system, one fact remained crystal clear. This fact was that the magnification of an object or objects without allowing one to be able to view details was virtually useless. However, a simple change was made by a man named Johannes Lipperhey. This simple change allowed once blurry objects to be viewed in crystal clear detail. Until this day it is a mystery as to how Lipperhey was able to discover a solution for this problem. Lippperhey somehow managed to figure out to place a ten millimeter piece of paper diaphragm in front of the lenses, which essentially helped funnel the
