Giant magnetic shield could make Mars habitable
Scientists at NASA have proposed that launching a giant magnetic shield into space to protect Mars from solar winds could give the Red Planet its atmosphere back and make it habitable for humans.
​New York: Scientists at NASA have proposed that launching a giant magnetic shield into space to protect Mars from solar winds could give the Red Planet its atmosphere back and make it habitable for humans.
Mars now appears to be a cold desert world and it has no global magnetic field. The cold temperatures and thin atmosphere on the red Planet do not allow liquid water to exist at the surface for long.
But it might not have been always so. Scientists believe that the Red Planet once had a thick atmosphere necessary to maintain liquid water, and a warmer, potentially habitable climate.
It is the collapse of the protective magnetic field billions of years ago that eventually made Mars what it is today -- cold and arid.
The researchers believe that the magnetic shield could helpMars regain some of its lost Earth-like habitability within the space of a couple of generations.
