Scientists Propose Jumpstarting Mars' Magnetic Field to Make It Habitable - Futurism

Now, scientists from a star-studded list of universities and organizations, including NASA’s own chief scientist James Lauer Green, are suggesting that we protect humans on Mars from deadly atmospheric conditions by jumpstarting the planet’s magnetic field.

So just how much of a magnetic field would be needed to protect Mars and the humans that might someday live on it.

Needless to say, creating a magnetic field would require massive resources; the absolute bare minimum of power needed would be around is around 10¹⁷ joules, which was nearly the entire power consumption of all humans on Earth in 2020.

Although the authors caution that they aren’t saying a magnetic field is necessary for life on Mars, it seems pretty difficult to imagine a sustainable Martian presence without it.
