But the thing that protects us is not geomagnetism, it's the ionosphere and the ozone layer, but they are regulated by different mechanisms. Have lightning storms on Mars and you will have ozone.

Now, according to MARSIS, the south pole of the planet Mars contains an enormous amount of ice, enough to engulf the whole planet in 10 meters of water. If we could focus a laser beam or some controlled explosion on this chunk of ice, terraforming Mars would be an much simpler process. "A much simpler process"? If you want to talk about terraforming Mars, you should start by figuring out how we're going to give it a proper, denser atmosphere and a warmer surface temperature. Then the ice would melt on its own, anyway (and stay melted, for that matter). Then we'd have to find a way to stop all life from getting irradiated to death by the solar wind, since Mars isn't protected by a magnetic field like the Earth is. I guess it's nice to know for sure that there's water there already so that we don't need to import it ourselves. But we still have a lot to figure out. Most people, however, don't realize that a laser is the most cost-ineffective and undesired thing after wooden sticks when you want to warm up something. And ffs a laser that could melt 1231231 cubic meters of ice would probably be powered by a nuclear explosion anyway, provided you can find an active medium that can stand such power. EDIT: I've just checked, Mars indeed has lower geomagnetism than Earth and is thus devoid of magnetosphere. This has an effect on its environment and is the reason for thinning of its atmoshpere. Ultraviolet radiation is still being absorbed by ozone though and radio frequencies by ionosphere. Magnetoshpere deals with particles not photons (that are, as em-field bosons, not affected by magnetic field directly) but those can be as dangerous as photons to life. | ||

but none of these methods really work, because even if you use nukes for heating (barring atmospheric effects), the increase in temperature will be only temporary. planets dissipate heat very rapidly; consider how much cooler it is on earth at night to see how fast the heat dissipation works. To make a permenant change you have to use a constant source of energy for heating. The sun, for instance. Therefore the only plausable approach, IMO, increase the amount of greenhouse gases on mars (using engineered life forms or nanotechnology), in a controlled manner, until average temperature reaches something reasonable, then somehow work towards making the atmosphere breathable without lowering the temperature too much. I'm not sure any of this is even possible with our current technology. It should probably be feasible to start it with 22nd century tech There's also a problem with the atmosphere of mars, because it has smaller mass, and thus gravitational pull, its atmosphere is thinner than earth's. It isn't going to be as effective at blocking radiation as the earth's atmosphere. | ||

Does the word "coherent" mean anything to you?I think "lasers" is supposed to mean "masers" (in other words, the machine inside a microwave oven). And how is that energy inefficient? Last time I checked, microwave ovens were quite economical at heating stuff. Though since most methods of generating electricity involve something heating water in a boiler, we better use that heat directly rather than produce electricity and spend it on heating, which is ought to lose some energy along the way. but none of these methods really work, because even if you use nukes for heating (barring atmospheric effects), the increase in temperature will be only temporary. planets dissipate heat very rapidly; consider how much cooler it is on earth at night to see how fast the heat dissipation works.

This doesn't even mean anything, because ice doesn't absorb microwave energy nearly as effectively as water in liquid state. | ||

Terraforming: 1 transporting the necessary equipment to mars on a large scale. 2 Creating a suitable atmosphere Is the enough Oxigen, Nitrogene, and carbon in the soil and the polar caps to release to support the most basic liveforms to reach a cascade reaction. Nanotech? Engineered bacteria, fungus etc. Otherwise it takes a huge amount of energy to harvest these gasses. 3 creating a greenhouse effect so water stays liquid 4 Mars needs an ozonelair to protect the surface from to much UV 5 What about protection from solar flares? 6 are there enough geological formations that allow mining of metals, minerals etc. to set up industies with a minimal dependence on the very expensive supplies from earth. | ||
