  That's why we're going to need to build a portable mini magnetic shield. It might not be planet sized, but imagine having the auroras just out of reach. Plus, being able to say "Raise the shields" and it not be just a line in a movie would be cool on its own accord.

    It's possible, but that's also something that needs constant power and effort. Living in a cave or piling up rocks might be much more resilient

      It would also be useful on the ride to the new planet while in the metal tube for months on end.
