Mankind polluted Earth’s oceans and atmosphere in an impressive way. According to the European Space Agency (ESA) it also polluted space in such a way that it represents a danger for satellites for the next 10,000 years !
To their website: “Since 1957, more than 4,800 space launches have led to an on-orbit population today of approximately 13,200 trackable objects, with sizes larger than 10 cm.”
Additionally, any object bigger than a centimeter represents an important danger for satellites because of their speed. There are up to 600,000 of them in terrestrial space.
