Phobos could help create an artificial magnetic field on Mars; understand

a reclaim Mars It may not be necessary for future human exploration, as scientists consider some “primitive” means of survival, so to speak, such as Building shelters with a special type of cement. But reclamation will also be welcome, and for this it will be necessary to create a file magnetic field. now New study Provide some ideas on how to do this.

On Earth, the magnetic field is important because it protects us from the solar wind and helps maintain the density of our atmosphere for our survival. With its weak magnetosphere, Mars has a much less dense atmosphere. If an astronaut inadvertently takes off his suit on the Red Planet, the water in his lungs, eyes and saliva will automatically boil, according to scientists.

Our magnetosphere is created by the dynamo effect in the Earth’s core, due to the convection of iron alloys. But the interior of Mars is much smaller and cooler than our planet, and we can’t just heat it up to create a dynamo. However, in theory, there are other ways to create an artificial magnetic field, some of which have already been presented in the past and others are described in a new scientific article.

The study suggests that the artificial magnetic field can be created by a strong flow of charged particles, both in and around the planet. As we already know, the first option is not very viable for human technology, but the second idea seems a little more feasible. The authors propose to create a ring of charged particles around Mars with the help of Loa Phobos.

Phobos is the largest of Mars’ two moons and orbits the planet very closely, so it orbits Mars every 8 hours. So the team proposes using this space object, ionizing particles from its surface and then accelerating them so that they create a hoop of plasma along the orbit of Phobos. This would be enough to create a strong magnetic field capable of protecting Mars and enabling it to reshape. Also, the plasma ring would not harm our satellites around Mars.

At this point, you might be wondering what a “but” is, so far the idea seems relatively easy to implement. Well, the problem is the engineering challenges to get the job done. The minimum energy requirement would be about 10 joules, which is equivalent to nearly all of humanity’s energy consumption on Earth in 2020. This means that using nuclear fission reactors as an energy source may be necessary if we want to modify Mars to allow future explorers to live in some comfort there.
