NASA Has Plans to Give Mars a “Magnetic Shield” to Enable Colonization
Many scientists and science fiction enthusiasts have, over the years, speculated at the possibility of terraforming Mars. Finding innovative ways to make the surface of the red planet gradually more conducive to human living. There have been many ideas and models created in the hopes of successful terraforming. Engineers designed a shell that could be placed around a small planet which could protect the planet from radiation and help to facilitate an atmosphere over time. Others thought that by breaking apart the Martian crust they could release enough CO2 to build up an atmosphere. There have been many attempts, but the issues of cosmic and solar radiation paired with the unsurvivable atmosphere and dry terrain are always too much.
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. Not impossible, but currently posing serious obstacles.
