NASA's plan to make Mars habitable for humans

NASA's plan to make Mars habitable for humans 

Mars used to look like Earth. The planet had a vast sea under oxygen rich skies. And as far as we know, all the right conditions for life. But while Earth was beginning to see its first glimpse of life, Mars was losing its chance of becoming a habitable world.

We don't know why, but roughly 4.2 billion years ago, Mars's magnetic filed disappeared. That magnetic field protected the young planet from a constant barrage of solar winds ejected from the sun. But once it was gone. Mars's warm, rich atmosphere was blown out of the solar system. And all that's left now, is the rocky, cold and inhabitable planet we know today.

Could we make Mars habitable again ?

NASA might have new strategy to do, just that they theorize that placing a larger magnetic dipole shield between Mars and the Sun. This can protect the planet from Sun's solar winds. And perhaps establish a new atmospheric equilibrium.
                Mars would live in the dipole's magneto tail essentially restoring its lost magnetosphere, giving the planet a chance to reestablish its long lost atmosphere.
