NASA has just provided an innovative proposal on “how to protect what is left of the planet Mars” and also facilitate crewed missions to the planet in the future: safeguard the planet with a magnetic shield.
We all know that Mars has water, which is essential for all forms of life but it is all ice. The red planet (Mars), was not always a cold and murky planet with a cold weather environment. At least it was not like this around 4.2 billion years ago. The Scientists believe that the planet died due to the deterioration of its magnetic field and all this happened around 4.2 million years ago. As there was no basic protection, the planet was vulnerable to solar winds and other harmful forms of radiation as well, which eventually scraped of its environment bit by bit over the years.
Thus, the honorable Director Jim Green of NASA’s Planetary Science Division presented the fantastic and ambitious idea of blanketing the red planet (Mars) with an artificial magnetic field. Jim Green along with his team proposed the magnetic shield to be on the top of the L1 Lagrange Point which is beyond the red planet itself, allowing the shield to generate an artificial magnetosphere which deflects the solar winds and harmful radiations which are affecting the planet Mars.
The director Jim Green said that new research is coming about due to the application of full plasma physics codes and laboratory experiments. He added that in the future it is entirely possible that an inflatable structure can generate magnetic dipole field at a level of about 1 or 2 Tesla as an active shield against the solar wind.
NASA claims that it will restore some of the planet’s water
“It may also be able to melt the carbon dioxide ice at the north pole of the planet Mars (greenhouse effect), owing to the magnetosphere’s thickness,” this is suggested by the Simulations of this magnetosphere. This may also be able to restore some of the planet’s water, which will be for sure much friendlier to long-term visits to the planet Mars.
These conditions would also allow all the explorers to study the planet in great detail, and also they could certainly pave the way for the colonization of Mars. But this will happen if the conditions can smoothen out and become habitable again. Till then, both SpaceX and NASA would have to wait for their ambitious plans of colonization to be executed.
