Space garbage

European Space Agency (ESA, in the acronym in http://www.esa.int/esaCP/index.html) English divulged in this tuesday images of the space garbage in orbit in return of the Land.
According to agency, between the first launching, in 1957, and January of 2008, about 6 a thousand satellites already they had been sent for the terrestrial orbit. Of these, only 800 would be active and 45% would be located to a distance of up to 32 a thousand kilometers of the terrestrial surface.

Beyond the disactivated satellites, the satellite photos show space residues as fragmentos of space aircraft that if they had broken, they blown up or they had been abandoned. In accordance with the ESA, approximately 50% of the objects that can be tracked is derived from explosions or collisions in the terrestrial orbit.
The launching of the Sputnik - the first artificial satellite, launched in 1957 for the Soviets, marked the beginning of the use of the space for science and the commercial activity.

During the Cold War, the space if became the main land of competition between the United States and the old Soviet Union - a dispute that reached its apex with the race to conquer the Moon, in the decade of 60.
By occasion of the Olimpíadas of Tokyo, in 1964 the first satellite of television for the terrestrial orbit was launched, with the objective to transmit the Olímpicos Games.

Later, the Russian launchings had diminished and other countries had inaugurated its space programs.
A estimate of the ESA indicates that the object number in the terrestrial orbit grew in steady way since the first launching. According to given, about 200 new objects they are launched every year.
In 2001, the American researchers Donald Kessler and Philip Anz-Meador, that study the space garbage, had affirmed have a possibility of that, in twenty years, already it is not more possible to carry through operations in orbits next to the Land.
