But these constructions all leave behind scrap metal, which continues to orbit the earth at high speed.

For almost 60 years, Americans, Russians, numerous other nations and an increasing number of private companies have been launching rockets and satellites into space. Once these rockets and satellites exceed their lifespan, they usually remain in orbit. Millions of pieces of debris are now orbiting hundreds of kilometers above our heads, at breakneck speed. 

Scientists warn that space exploration beyond our planet will be almost impossible in 30 years' time because the debris will be out of control. This space trash will also affect the communication systems that structure our everyday lives.

How can space debris be captured and disposed of? It’s a question that is becoming increasingly urgent, if we want to avoid impending disasters.
