Scientists at the United States Space Agency NASA are from the viewpoint that an artificial shield of the magnet can make the Red Planet habitable. It's not clear how we would go about restoring Mars' magnetic field, but we might be able to build an artificial one. The shield would allow Mars to slowly restore its atmosphere. But it might not have been always so. This would result in Mars' thin atmosphere thickening due to the greenhouse effect, which would turn the Red Planet warmer.
Mars L1 comprises an enormous dipole, which is a closed electric circuit strong enough to generate an artificial magnetic field, a report by Popular Mechanics stated.
A Nasa scientist believes that by putting a man-made magnetic shield around Mars, the conditions on the Red Planet will not be as harsh and will make it easier for humans to settle there.
And, while the concept of terraforming Mars isn't completely impossible, to successfully do it you would need to protect against cosmic radiation, solar radiation and solar winds, increase planet temperature, add oxygen and nitrogen to the atmosphere, and do all of this in a way that could be self-sustaining.
If all of this were to occur as the team anticipates - and admittedly, that's a pretty fantastical if - it's possible that, within the space of a couple of generations, Mars could regain some of its lost Earth-like habitability.
The planet Mars is shown May 12, 2016, in this NASA Hubble Space Telescope when it was 50 million miles from Earth.
It may be a dry and desolate world now, but Mars was once an active planet covered in oceans with a thick atmosphere. Jumpstarting global warming in the planet would affect its temperature and melt water ice and carbon dioxide ice.
"A greatly enhanced Martian atmosphere, in both pressure and temperature, that would be enough to allow significant surface liquid water would also have a number of benefits for science and human exploration in the 2040s and beyond". There are planned missions to the Moon, and the first pioneers from Earth will voyage to Mars.
Now, onto the magnetic shield. The L1 Lagrange Point is a location of gravitational equilibrium that ensures the structure remains between Mars and the sun.
While the idea may sound wildly out-there, Green's group says that new research, including lab experiments and the application of full plasma physics codes, is showing that small-size magnetospheres can be used to protect spacecraft and human lives. Jim Green estimates that one-seventh of Mars' ancient ocean could be restored.
Even if we were to dump more atmosphere into Mars, it would just be stripped away again.
Researchers noted that although the plan is hypothetical at this point, a small scale magnetosphere that operates on a similar premise does exist and could serve as the model for an huge shield.
