Today, space debris has become the nightmare of telecommunications operators and space agencies. Since the beginning of the conquest of space at the end of the 1950s, the number of spacecraft launches has multiplied. Many of them, now useless, wander above the Earth and sometimes collide. Satellites carrying nuclear charges, stages or tanks of launchers have already fallen back to Earth, without causing any casualties until now. Faced with the danger, space actors are now constantly monitoring the clouds of waste, ready to divert their satellites or installations in an emergency.
