OK, but how would we strengthen Mars' magnetic field so that it can block out radiation?

might not be possible with any conceivable technology, as it would involve rebuilding Mars so that it had a substantially mobile magnetic metallic core. according to Tim Sharp at Space.com, Mars' center probably has a solid core composed of iron, nickel, and sulfur of roughly 1,800-2,400 miles in diameter. The core is immobile, and so Mars has no magnetic field. Without the shield of a magnetic field, radiation bombards the planet making it relatively hostile a place compared to Earth.


Couldn't we build an external one, like an exoskeleton of sorts? I was thinking maybe they could start out making a relatively small "habitable zone", then they could spread out from there. Like the way I'm thinking of it, you could put up some radiation-hardened towers, and find some way to generate a magnetic field between the towers, then put your bases or whatever in the middle surrounded by the towers.

it has to be mostly planet-wide or the bulk of the atmosphere would take the path of least resistance into space.

Are you talking about Uranus and Neptune, or Mars?


He probably meant Uranus and Neptune (the two farthest from the sun true planets). Mars is one of our two next door neighbors. Though its not exactly balmy either.

mars is like the kernel of corn in the cosmic popper that didn't quite pop.

Ah, but I wouldn't implement an atmosphere until it's planet-wide. In its starting phases, it would just be a radiation shield, nothing more, nothing less.

maybe an advanced level 1 [kardachev scale] civilization might be able to swing it. for reference, we are level 0 at present.

Of course. I wasn't implying we actually had the technology for it yet, it's just a little far-fetched sci-fi type idea I had. ;)

Thanks. :) I actually come up with ideas like this all the time, though being that I have no scientific background, and that the only science courses I've taken past 10th grade were the 11th grade levels of chemistry and biology, both of which I barely passed, I doubt anyone in the scientific community would take any of them seriously.

Correct?

the two moons of Uranus and the rings of uranus


Don't forget avoiding the event horizon of the black hole. :lol:

First we have to learn how to send a person further than the moon before we start worrying about terraforming planets and setting up colonies. We're not quite as advanced as we often pretend to be! A big reason for that is that space travel, in its current state, is a huge money sink and doesn't generate any profits. If we could find a way to make trillions of dollars by sending people into space, I'm sure we'd have colonies on Pluto by the end of the decade!

I wonder how much could be made by mining the moon [among other business and industrial propositions]?

The unmanned progams are very profitable. Think of all the communication satellites out there They are what joins the world together.

The manned programs are money sinks.

Terraforming is a pipe dream. Even Mars can never be terraformed because it has no magnetic field as a result of geological death.

If Ur anus is big enough to terraform I would suggest laying off fast food.

Sorry guys, I couldn't resist :cry:
