NASA Considers Magnetic Shield to Help Mars Grow Its Atmosphere
Popular Mechanics ^ | Mar 1, 2017 | Jay Bennett

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.

Liquify the core? That’s a lot of mass.

Not to worry. NASA has already selected to mission crew.

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.

Not really. Reading the article, the shield would be at the Sun-Mars LaGrange1 point 1 million Km from Mars and more than 70 Million from Earth at the closest. Disruption to Earth's magnetic field would be miniscule - and downstream with respect to the solar wind.

What happened to Mars 6,000 years ago?

Genesis 1:14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: 15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.

I’ve been turning over ideas for a Mars-global artificial magnetic field for a few months now. If we want to make the planet truly habitable we need to warm it up, but without a magnetic field the solar wind would simply strip it away at a faster rate as heat expansion made the atmosphere larger.

Any global field would require a lot of energy due to the flux, but it wouldn’t have to be very strong at any one point (although I’ve been mulling the benefits of large distributed infrastructure that produce weak fields over a large area vs. large numbers of small infrastructure elements that each produce very strong fields in a small area).

We don’t need a global magnetic field on Mars to establish an outpost, but if we plan to have humans stay there forever, then we do need one. The technology isn’t new by any stretch, but we’ll need to establish real manufacturing on Mars to make it happen.

They could also drop rocks on us from Mars.

I can’t believe the PC dweeb at the end of the presentation who said that “Let’s take it” sounded imperialistic to him and asked if the presenter was speaking as a human or as a representative of the United States Government. I so wanted to kick him in the sack.

In another 500 to 1000 years it might be possible.

No, us hardasses or our descendants would, and the libtards would show up after to leach off the invested sweat equity...

Wouldnt the water evaporate and block the weak sunlight...cooling the planet? Dont you really need enuf gravity to hold the gases in the atmosphere...for colonization...probably better to construct underground magnetically shielded environment...either way...a daunting problem...will earth last that long? Will our progeny die on a lifeless mars?

I thought Mar’s relatively weak gravity was the reason for it’s thin atmosphere.

Suddenly occurs to me:
“So you are saying you want to create Global Warming?”

The irony is rich...

It’s science and there is a consensus on this thing.

Get with it, heretic...

The arrogance of “man”.

This is RIDICULOUS. PREPOSTEROUS. HUBRIS.

and in trying, What could possibly go WRONG?

Anybody knows all we need to do is...

“... go in, set up these big atmosphere processors to make the air breathable. Takes decades. It’s what we call a shake-n-bake colony.”

Aliens (1986)
