Posted on 03/01/2017 6:58:45 PM PST by BenLurkin
Such a shield could leave Mars in the relatively protected magnetotail of the magnetic field created by the object, allowing the Red Planet to slowly restore its atmosphere. About 90 percent of Mars's atmosphere was stripped away by solar particles in the lifetime of the planet, which was likely temperate and had surface water about 3.5 billion years ago.
According to simulation models, such a shield could help Mars achieve half the atmospheric pressure of Earth in a matter of years. With protection from solar winds, frozen CO2 at Mars's polar ice caps would start to sublimate, or turn directly into gas from a solid. The greenhouse effect would start to fill Mars's thin atmosphere and heat the planet, mainly at the equator, at which point the vast stores of ice under the poles would melt and flood the world with liquid water.
"Perhaps one-seventh of the ancient ocean could return to Mars," said Green.

What could go wrong dont mess with mother nature
Very cool. Where there is water...there can be beer.
Agriculture and fire directly mess with mother nature.
It seems to me that, if they want to grow the atmosphere, they need to grow the mass of the planet. Mars isn’t that much bigger than our moon and its lack of gravitational pull would make it hard to hold onto an atmosphere.
The future of Man doesn't lie in gravity wells.
Horrible for Earth, but OK on Mars?
NASA is missing a great opportunity. They should restrict movement of people to Mars to only Democrats. Exclude the frozen CO2 since Democrats know that CO2 is VERY harmful and let them live their wonderful Democrat life in a CO2 free atmosphere!
The cool thing about this, is that if the magnetic poles on Earth are about the change, and if in the interim the magnetic field dies down significantly, then a similar apparatus could be placed between the Sun and Earth during the transition to protect our atmosphere.
You talking for Marvin?
So what if he gets very, very angry [again]? Who cares?
What's he going to do-- send us an earth-shattering ka-boom?
Here in the U.S. they want to prevent global warming while in space they evidently want to increase global warming.
I remember an old SF novel - “The Sands of Mars” by Arthur C Clarke. They solved the issue by lighting Deimos on fire to create a new sun IIRC.
Amen! I’d buy martian beer on mars.
Funniest two-liner ever.
Here is just one example of what could go wrong:
An artificial magnetic device capable of protecting Mars from solar winds etc. may disrupt the magnetic field of Earth that protects all life here from solar winds and other radiation. The disruption would be at a maximum when Earth and Mars are in conjunction (i.e., aligned). Then we get baked.
IOW, it could kill us all.
. So when they figure it out that it was only about 6,000 years ago, I assume that would be a bit of a problem for the theory behind this scheme, no?
What happened to Mars 6,000 years ago?
