Space research-human fascination with outer space

The idea of space research is vital, for space research has fascinated humans for as long as there was an understanding of outer space.

For many years human beings believed the Earth was flat and if they went too far on Board would fall. But even with this idea dangerous, a space was never far from the minds of those more adventurous types.

Explorers Grecian and azteca, used to describe the Earth as a flat surface and it was a Greek mathematician, Eratosthenes, calculated as the diameter of the Earth by a simple technique to use the shadows cast by the Sun. But people were intrigued by what lay over the land and wanted desperately to find ways to go into space, the search for other planets and perhaps other forms of life.

For thousands of years of research space applications continued to dominate all of those who were fascinated by what was contained in the universe. Astrologers and astronomers tried to answer questions, but, for the most part, seeking space remained a big black hole, until the 20th century. In the twentieth century was that astronomers and scientists begin to look scientifically at what was out there and the possibility of an expedition to space research. And, in April 1961, Yuri Gagarin did what so many others had wanted to do before him and became the first man in space.

Gagarin's triumph was the culmination of a battle between USA and Russia-each country wanted to be the first to put a man into space and begin an era of space research. The Americans had Alan Shepherd waiting in the wings broke off into outer space and had little or no idea that the Russians were ready with Gagarin.
Shepherd became the second man in space and to start a search space only a few weeks later, when he was fired for about 15 minutes.

Since then, the search space has been a constant battle between the two countries with the United States astronauts and cosmonauts from Russia, striving to explore more, to find more and more space.
Space research has some major hot showers in recent years, particularly with the Challenger in 1986, which was destroyed only a few minutes into its flight and, more recently, with the Columbia broke up in 2003 that the re-entry into the Earth's atmosphere, killing all aboard. Space flights did not resume until 2005, with attention being paid to them around the world.
International space station is still in use, with a skeleton staff on board.
Until man has conquered every corner of the known universe, that would seem to be a feat unlikely, it seems that humans will always be obsessed by space research. Is fear of the unknown, as well as the chance to explore other forms of life that draws us closer. Right now, Richard Branson is preparing to take the first space tourism flights in the atmosphere, and it is not clear where it will stop the charm.
