It’s red alert on our skies. Above us there are indeed hundreds of millions of pieces of garbage space travel in different orbits ranging from the lowest, between 200 and 2000 kilometers, to the geostationary one of 36,000 kilometers. But that is not all. According to the data provided by Day there would be 30,000 debris larger than 10 centimeters (there are also satellites, now dead, as big as a wagon), more than 600,000 pieces ranging one to ten centimeters and a few hundred million smaller than a centimeter like paint flakes, bolts and particles created by collisions. A news that, when compared to the Chinese rocket in free fall in these days, is much more worrying.

In space there is really everything. Indeed – continues the newspaper – floats an astronaut’s glove of Gemini 4, lost during a spacewalk and the camera of Michael Collins that got out of hand during the Gemini 10 mission. Although small and insignificant these objects, if they get close to the atmosphere, arouse terror. So much so that it is necessary to rethink the disposal of this real space junk.

“To private space agencies – he admitted to Day professor Roberto Battiston former president of ASI (Italian space agency), who has repeatedly concerned himself with the problem – cleaning up space is relatively interesting because of the heavy investments that are necessary. National Agencies are taking care of it and carrying out projects that are in an advanced study phase. We talk about build the next satellites with a particular system that, at the end of their life, projects them into a cemetery orbit where they do not constitute a danger for the future. Another study is to send particular satellites that with of the pulverizzino lasers the larger fragments “. Battiston, however, wanted to reassure the most fearful, explaining that very few debris fall on Earth. The satellites and crews of space missions are more at risk.” The impact with a spacecraft – he explained – it could even be fatal even if it’s a simple bolt. ”In short, setting your eyes to the sky doesn’t seem like such a bad idea.
