Terrastializing Mars..........How?

An atmosphere alone will not provide enough protection from cosmic radiation. You need a strong magnetic field for that. Cosmic radiation is indeed lethal to human life, and the exposure limit is quite small. This is one reason why proposed off planet habitats for both the Moon and Mars often depict structures buried in the local soil, to act as a shield from cosmic radiation.

A solid iron core wont do the trick. You need a separately spinning molten core to generate a strong enough field. Here is why...

A Wiki explanation of the Geo-Dynamo that powers up the Earths Magnetosphere:

The internal field of the Earth (its "main field") appears to be generated in the Earth's core by a dynamo process, associated with the circulation of liquid metal in the core, driven by internal heat sources. The Earth's core is hotter than 1043 K, the Curie point temperature at which the orientations of spins within iron become randomized. Such randomization causes the substance to lose its magnetic field. Therefore the Earth's magnetic field is caused not by magnetized iron deposits, but mostly by electric currents in the liquid outer core. Convection of molten iron, within the outer liquid core, along with a Coriolis effect caused by the overall planetary rotation that tends to organize these "electric currents" in rolls aligned along the north-south polar axis. When conducting fluid flows across an existing magnetic field, electric currents are induced, which in turn creates another magnetic field. When this magnetic field reinforces the original magnetic field, a dynamo is created which sustains itself.

Thus a solid iron core would not produce the same type of magnetic field, if any at all. You need a liquid iron core that is hotter that the Curie point temperature, to create the electric current that drives the magnetic dynamo.

(As a side note, "Geo" means Earth, thus Mars would not have a Geomagnetic field. In addition the Magnetosphere is not actually spherical in shape, The solar wind makes it somewhat oblong)

True, but it would provide more protection than if one did not exist at all.

Well I'm terrible at paraphrasing something if I have'nt memorized it, so here's the
article about what I was thinking about.

Hundreds of miles below, however, a molten sea of iron, nickel and sulfur churns. And new research suggests the gooey core will eventually solidify-either from the outside-in, forming an iron-nickel core, or from the inside out, forming a core of a fool's-gold-like minerals.

Andrew Stewart, a planetary geochemist at the Swiss Federal Institute of Technology, said Mars' cooling core might restore magnetism to the red planet. "If liquid metal moves around a solid core, it could create a natural dynamo like the one found in Earth's core,".

Personally though, I like the idea from the older thread about using strategically placed
Iron asteroids in orbit as a way to protect the planet.

Would it not be more feasable to alter humans to live in differant enviorments rather then trying alter an entire planet or moon? Just trying to think outside of the box

Considering that Mars also appears to be warming right along with Earth, we may be able to just sit back and watch the ice caps melt. However when the system-wide warming trend wanes, it will be a total kill-joy for any terraforming efforts underway.

No matter with the missing magnetosphere though. Just be sure to bring your SPF 5,000,000 lotion. You'll be fiiiiine.

Yes, that would indeed be a possibility, though bioforming (the term for altering the
organism for its environment) in the near future (next hundred years or so) would not
allow one to just live on Mars as is, since even if you could do with breathing the
incredibly thin atmosphere and it's abundance of C02 and survive the hard radiation and
extreme cold, you'd still need food and other such essentials.

All in all we most likely will using bioforming on permanent Martians, if for nothing else than
to adjust there bodies to be able to act normally within the low gravity environment.

It's a good idea by the way, and really one that I see few people really think about.

That is somewhat like saying that wearing a T-shirt is better that wearing nothing when you are getting shot at.

Cosmic radiation is no joke, and it easily goes through a relatively thin atmosphere like a 9mm bullet through a Disney sweatshirt. The only thing keeping us safe here on Earth is the magnetosphere and not the atmosphere. The atmosphere is OK for filtering out some of the Suns less harmful radiation, but it does almost nothing for cosmic radiation. Most cosmic radiation does not originate from the Sun. Only the Earths magnetic field shields us from the more serious stuff. High energy neutrinos regularly pass right through the Earth like it wasn't there, and only the Magnetosphere deflects the more harmful stuff. Cosmic rays can have energies of over 1020 eV, far higher than the 1012 to 1013 eV that man-made particle accelerators can produce. Ionizing radiation such as Alpha and Beta particles, X-rays, Gama rays, Muons, Protons, Pions, and Neutrons cause DNA damage and death. The scientific research base shows that there is no threshold of exposure below which low levels of ionizing radiation can be demonstrated to be harmless or beneficial. The health risks – particularly the development of solid cancers in organs – rise proportionally with exposure. Cancers associated with high dose exposure include leukemia, thyroid, breast, bladder, colon, liver, lung, esophagus, ovarian, multiple myeloma, and stomach cancers. United States Department of Health and Human Services literature also suggests a possible association between ionizing radiation exposure and prostate, nasal cavity/sinuses, pharyngeal and laryngeal, and pancreatic cancer.

The research done by Andrew Stewart regarding the possibility of a cooling solid/gooey planetary core generating a sufficient magnetosphere for Mars is less than conclusive. It is based on guesses and even then he only offers it as a possibility. He clearly states that he needs more data to determine if it is even possible. As we have no examples of such a system we have to rely on the current fact that the magnetosphere of Mars is almost nonexistent. If we are to consider terraforming Mars in the next century, as this topic started on, then we must include a manner of generating a protective shield for the planet. I'm just not certain how we would go about that. Generating an atmosphere is far simpler than generating a magnetosphere by comparison.

Quick question, could you use atomic explosions or something like that to help make an atmosphere?

edit: or to help with what ever the problem is

[edit on 26-6-2007 by earth2]

Yes, you could. Nuke = radiation. You could also build a giant mirror in space and reflect heat down to boost a certain spot by 10 degrees. Giant mirror = expensive. Or you could bombard mars with asteroids to increase the temperature with very little damage to us when comes colonizing time. Asteroids = FTW!?!?

Terraforming Mars is wrongminded as we now conceive of it,since there are living people and animals at the surface who don't even know us yet. We can't just go forward blindly affecting /effecting a planetary civilization we currently know so little about.That would be like the "War of the Worlds " in reverse. Nasa,by keeping GOOD SCIENTISTS with great minds in the dark has allowed us to think in totally wrong directions for lack of basic info on the lifeforms currently thriving on Mars. Now,that said,in the future there may be a joint need for some type of similar mutual plan to regenerate Mars atmosphere to some former level,a sort of recovery project.But that would be up to the leaders of Mars civilization,not solely the Earth people. That would be invasive if done against the will and approval of Mars people. It may be an important bargaining tool in interplanetary trade.The first step should be communication with them. You see 2 Mars people from the same panorama of Spirit rover? Well I can. I work for them as an advocate.

could a system like HAARP be used to create a magnetisphere? or is it possible to use HARRP to make or own grow? stretch it round mars?

If you had a system set in the northe and one in the south could you create the ness protection?

I was watching a program last night that raised the possibility that 1/3 of Earth's gravity would not be enough to sustain for ourselves a healthy life. Though the fellow doubted it, he did raise it as a possibility.

Maybe mars in going to be easy to terraform, because it has always been capable of supporting life. Just a thought.

If any of you recall pictures of mars from the late 70s/early 80s, mars always had these giant pole caps, just like earth. Now they are gone.

In the late 70s/early 80s, pictures from mars ALWAYS showed a red sky. Now, pictures show it as blue. I wonder why that is?

Maybe terraforming is going to be "easy" by the end of the century because they are already doing it.

Two faced mars...Inversions rule this planet.

Why is the Phoenix a theme?

To rise from the ashes to live again. The truth is a hard pill to take.

The lie - truth, yin yang the dragon that chases it's own tail rules us as we speak. It's the two sided coin with two heads. They are the coin! Literally.
What you think the trillions the Fed has is even close the untold vast riches of the leaders in the darkness? To only look at the light you blind yourself with pride.

You really think the faces and the structures are just a hoax? Mars is the symbol of a religion that rules us. The sun of god. Laugh all you want, but it's those are told what to think who can't see their hands in front of their faces.

Not only is Mars terraformed our favorite Area 6 is too. Look what's just been posted. www.youtube.com...

Stairway to Heaven.

There are two paths you can go by, but in the long run there's still time to change the road your on.

The inverse of this is found on the internet look it up. It again is no accident.

V is the two false choices that power the lie of control.
Invert the lie to reveal the devil between the lions.

EVIL

The only way to see the light is to not allow the pipers music to tell you what to think.

Inversions - Divided they Stand

Again this isn't by chance. Are you listening can you understand?

Mars it'self shows the law of control. To be a ruler on Earth you must know the law or you will not be allowed to live.

The Christian message has been perverted by those who worship the Phoenix. Why? Because who we pray to isn't who we think he is. Jesus on the cross is really an image of us riding the dragon. Human sacrifice.

The upside down cross is the Phoenix.

Still not just by chance.

We are about to witness the birth of Mars and the rise out of the shadows of the scary ones.

The arctic is being treansformed too. Why? Look at which way all the faces on area 6 align with.

Get it yet? Are you listening to the harrp play? Is it downing out reality?

The angels aren't going to greet you with fluffy wings.

They will greet us with fire.

Do you think that this is still just all by chance?

The number 11, 23 showing up everywhere? You think this can just happen? If you've ever programmed anything you know nothing is built without planning. It's not random. It's perfection.

They own it, everything. You the lie, the coin everything. Still chasing the dragons tail to find the truth are we? You will never be told the truth without a lie following. Never, it's the way of their GOD and of the Face that always faces the light and has a face you never see.

THE MOON is this representation. The two faces, yin yang, the dragon.

Still not awake are we people?

When you wake up, don't allow the Happening message tell you to give up.

Because it's a lie.

We are told the truth, you have to find it.

Though I walk through the valley of the shadow of death I shall fear no evil.
There is nothing to fear but fear itself. (he knew)

Give me the child (real jesus). Through dangers untold and hardships unnumbered, I have fought my way here to the castle beyond the Goblin City to take back the child that you have stolen. For my will is as strong as yours, and my kingdom is as great...(he knew)

Ok did you shave your head or something? I swear the radiation is creating static in your brain. You wonder what the military shaves your head? Why do wizards of lore have long hair? Again you all this it's just by chance.

Mc-fly hello are you in there Mc-fly? Oh yeah you wouldn't want to talk back to the Bully now would you?

All you have to do is believe and not be afraid.

Divided they Stand...

Only together though unity are we free. The UN is an inversion.

It's time to crawl out of your cave. Dyings easy, it's living that's hard.

Don't believe and the pipers music will take you away.

I think terraforming Mars is a waste of time thinking about it without the current life on Mars part of the equation and solution.The people on Mars may be against the plan from the outset as tampering with their environment.However,if by the time we can communicate with Mars people and have a building environment coalition,with all in agreement,we could proceed in slow and gradual building so as not to harm but indeed help the native humanoids and animals.There may well be other advanced species on Mars we currently know nothing about,so their considerations would be taken into account if they are known to exist(from native info).That's the wild card right now,advanced Mars species besides the native Mars humanoids. Much more important than any terraforming considerations are the first steps in Mars humanoid to Earth humanoid communications. We desperately need to talk to them and exchange info before we ever go there.They have the shortcuts to knowledge that we require.
