Remains orbit the Earth in an uncontrolled way and add up to 166,000 million waste of a diameter greater than one millimeter and less than one centimeter. Some 750,000 are between one and 10 centimeters in diameter. Another 21,000 are much larger.
If we continue at this rate, space junk it will prevent us from traveling within a century without risk of collision.
Invited to the space conference that the European Space Agency (ESA) has held this week in Darmstadt and attended by 400 experts from around the world, the prediction of the hundred years are words of astrophysicist Donald Kessler, to whom we owe the definition of the so-called Kessler effect. His exact words were:
In a hundred years, we will no longer be able to put more satellites into orbit and travel to space will have become too dangerous, because it will be almost inevitable not to collide with any piece of space scrap. Something needs to be done as soon as possible and, unfortunately, NASA's budget for the space debris problem has not changed in the last 20 years, which means that more will be necessary with fewer resources.
Although some technological solutions are being projected to solve this problem, Kessler is skeptical because they are technologies that have not yet been tested. It suggests, therefore, that stricter regulation is necessary first of all, and that satellites should be constructed more impact-proof.
