In the future, the Earth's orbit can be cleared of faulty satellites using a space tug using magnetic forces.
Magnetic attraction is considered a safe method of cleaning the orbit from metal debris left by previous missions. Every year the problem is becoming more serious, and more debris. And to cope with it is not so easy, because some fragments reach several tons in weight and at such speeds can harm not only working equipment, but also cosmonauts on the ISS.
Various methods are considered as methods of struggle, including nets, harpoons and even robots. Emilian Fabach from the University of Toulouse (France) is now offering magnetic capture. This will ensure garbage collection at a safe distance.
Darwin’s planetary flotilla of six telescopes and satellites will be observed from space to analyze the atmospheres of terrestrial planets. This mission is still pending. Emilian proposes to use a magnet to push satellites out of orbit or destroy them. Moreover, such devices do not need to equip in advance. The tug will focus on electromagnets taking into account the magnetic field of the Earth.
A strong magnetic field will be generated using superconducting wires cooled to cryogenic temperatures.
Space tugs using reliable electromagnets and the planet’s magnetic field can be used to remove defective satellites from Earth’s orbit.
Such mechanisms will work from a distance of 10-15 m and guarantee accuracy up to 10 cm. Emilian argues that he will be able to build a model taking into account the constantly changing state of the earth's magnetosphere.
