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.
