The International Space Station

The International Space Station.
The Space Station could say it's like a floating laboratory in space also remains in orbit at an altitude of 400 km above Earth and humans will host for the next 10 or 15 years. The International Space Station is the biggest structure created by the human being who has " surfed" the space. The Space Station weighs about 450 tons and measured as a football field . Inside the Space Station be a crew of up to 7 people who made ​​countless experiments and investigations. Today, there is a powerful enough to transport the space station from earth to space rocket , therefore, the Space Station is carried by parts. It's like a puzzle of 100 pieces to be transported on 50 spacecraft launches . In the Space Station are 4 laboratories : Russian ' Zvezda ' American 'Destiny' , the Japanese Kibo and European ' Columbus ' .
Europe , through the European Space Agency Space is exclusively responsible for the Columbus laboratory and another essential element of the season: the Automated Transfer Vehicle
European participation :
The first European to visit the ISS was the Italian Umberto Guidoni , who traveled in April 2001 . Many of the brightest minds in Europe are working at the forefront of science and technology of the XXI century
Where is the European season:
The ISS orbits the Earth in an orbit approximately 400km away from this . When weather conditions permit, the ISS can be seen from Earth as if it were a star . Although the ISS always follow the same orbit on its way , not always pass through the same point on Earth . The orbit of the ISS covers 85% of the surface of the Earth , including countries that are home to 95% of the world population.
How to get the ISS stay in orbit :
To put the ISS into orbit a rocket help is needed. To reach orbit and stay in it, the ISS needs a certain speed . The velocity necessary to remain in orbit depends on the distance from the Earth . If the speed is too low , the ship would fall to Earth. If the speed is too high , and would ship fired into space . To build speed, it is necessary to apply a force to accelerate the space station. If the applied force is not enough, the force of the earth ( gravity) will pull the ship back to Earth. If excessive force is applied , the forces of gravity on Earth will not be powerful enough to keep the spacecraft in orbit.
Personal opinion:
In my opinion this article on the International Space Station is very interesting, because it was unknown and a topic that has very interesting sections that almost everyone know. It is an article with which the children can learn and play.
