Space Exploration
Space Exploration is the quest to use space travel to discover the nature of the universe beyond earth. Today's Space Exploration started in 1957 with the launch of the first artificial satellite, but since ancient times people have dreamed of leaving their home planet and exploring other worlds. Every era through out history has had a belief as to what the "heavens" are made form. The Greeks believed that the stars and space were made of a material called "Quitenses", and other culture once thought that the stars were made of their peoples passed away. We know now what stars (or suns) are really made of; they are made of various gases that explode over and over again.Mankind has come along ways from the days when we could only guess what was out there. The history of Space Exploration really began in 1957 with the launch of the first artificial satellite, Sputnik 1, sent into space by the Soviets. Up until about 43 years ago people did not have the means to travel to or send objects into space. The hardest part of traveling into space was developing rockets that were powerful enough and reliable enough to boost an object into space. These rockets needed more then just brute force, they also needed a
Over the course of the 43 years of today's space Exploration history, there have been three major tragedies. There were two tragedies in 1967, with the explosion of the Apollo spacecraft at cape Kennedy and with the twisting of the parachute lines in the Soyuz spacecraft. The third tragedy happened in 1986 with the explosion of the spaceship Discovery, on aboard were seven people. This marked a day in space history because it was the first time that a person with a cause was going into space. This person was a schoolteacher who tragically, also died in the explosion. 1.
