Did you know that more than 600,000 objects described as space junk orbiting the Earth today?

 Now that, through the U.S. space policy issued by the government of Barack Obama, NASA and the Defense Department have increased responsibilities (especially pressure) to clean up orbital, have decided to begin lobbying and awareness explaining where has appeared much "filth."

Of the 4700 space mission (known) that have occurred since the beginning of the space program, one third of the total space junk that orbits the planet Earth is the product of only 10 space missions. Of these, six were held in the last 10 years. United States, China and the former Soviet Union are the main contributors.
