Satellites
Satellites Satellites Satellite is probably the most useful invention since the wheel. Satellites have the capability to let you talk with someone across the nation or let you close a business deal through video communication. Almost everything today is heading towards the use of satellites, such as telephones. At&t has used this communications satellite (top right) ever since the late 1950s. TVS and radios are also turning to the use of satellites. RCA and Sony have released satellite dishes for Radio and Television services. New technology also allows the military to use satellites as a weapon. The new ION cannon is a satellite that can shoot a particle beam anywhere on earth and create an earthquake. They can also use it's capability for imaging enhancement, which allows you to zoom in on someone's nose hairs all the way from space. Robert Gossard (left) was one of the most integral inventors of the satellite. He was born on October 5, 1882. He earned his Masters and Doctoral degree in Physics at Clark University. He conducted research on improving solid- propellant rockets. He is known best for firing the world's first successful liquid-propellant rocket on March 16, 1926. This was a simple pressure-fed rocket that burned gasoline and liquid oxygen. It traveled only 56m (184 ft) but proved to the world that the principle was valid. Gossard Died August 10, 1945. Gossard did not work alone, he was also in partnership with a Russian theorist named Konstantin Tsiolkovsky. Tsiolkovsky was born on September 7, 1857. As a child Tsiolkovsky educated himself and rose to become a High School teacher of mathematics in the small town of Kaluga, 145km (90mi) south of Moscow. In his early years Tsiolkovsky caught scarlet fever and became 80% deaf. Together, the theoretical work of Russian Konstantin Tsiolkovsky and the experimental work of American Robert Gossard, confirmed that a satellite might be launched by means of a rocket. I chose the satellite to research because many things such as computers, TVS and telephones are using satellites, and I thought it would be a good idea to figure out how they work and the history behind them before we start to use them more rapidly. I also picked the satellite because I think that my life would differ without it. For instance, The Internet or World Wide Web would run very slowly or would cease to exist altogether. We wouldn't be able to talk to people across the world because telephone wires would have to travel across the Atlantic, and if they did, the reception would be horrible. We wouldn't know what the weather would be like on earth, or what the stars and planets are like in space. We wouldn't be able to watch live television premiers across the country because all those are via satellite. A satellite is a secondary object that revolves in a closed orbit around a planet or the sun, but an artificial satellite is used to revolve around the earth... This is ONLY a preview of the article.
