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 tThis is ONLY a preview of the article. If you would like to view the entire document, you must subscribe to Electronic References. Please register below now!
