No. It has no magnetosphere so the atmosphere would just get torn away by solar winds.

Yes.

Yes. I'm scheduling for the beginning of the terraformation of Mars for 2044.

>Question One: If you terraform Mars, making it into a Garden of Eden, won't this be temporary, since Mars isn't big enough to permanently hold onto an atmosphere.
>Answer: You are absolutely correct. Mars is a small planet, and hence it's gravitational field is not strong enough to permanently hold onto a dense atmosphere, but it is sufficient to hold onto an atmosphere for thousands to millions of years, which is enough for us. Once we terraform Mars, there will be enough of an atmosphere to take of all our needs for generations to come.

Is that what's created because the molten metal in the core moves really fast or was that just a movie?

Holy responses to my post batman.

Interesting.

>>2008035
>implyinig we have spare molten iron to deposit in the core of a planet half the size of ours.

>>2008057
/sci/ has a hardon for a green and blue Mars.

>>2008061
Smash Mercury into it.

/Not serious

>>2008035

It's simple: We build a bunch of PATENT FUCKING PROTECTED (lol Zubrin) magsails in the Lagrange points near Mars, and block the solar wind. It's really that easy. But it should have a heavy counterweight as to not get pushed by the damn thing.

>>2008067
Then you have got to have some insane gravitational power beyond the power can master at this stage. Another star will do that, however all of the planets orbits will change too.

>Smash Mercury into it.

/Not serious

Actually thats really cool. Let's do that.

>>2008061
>Implying that's the only way to generate one.

>>2008077
The only thing stopping it from having an atmosphere is its lack of magnetic field to stop the solar wind from pushing it away. As far as I can tell...that would work.

After you set up that sail, however, you have to push phobos into mars. It needs to happen.

>Implying that's the only way to generate one.

Fuckin magnetospheres. How do they work?

Probably generated through large quantities of molten metal. Not enough iron? How about lithium or berilium? Them alkaline earth metals and alkali metals work?

>>2008079
Well, you either need a lot of power, or a lot of time. A single mass driver could do it, given enough time.

Mercury is much more useful for power generation, however, so wasting it trying to make Mars habitable would be silly. Making Venus habitable is, to me, a much more interesting challenge. It's also more feasible to convert the Venusian atmosphere than it is to give Mars and atmosphere.

>>2008102
Yesssss
Don't worry, I'll set up cameras to record the impact from right on the impact site, and many more on other parts of Mars. and some in space of course.

but surely if you plant enough trees- which love carbon dioxide- most of the atmosphere IS that, the trees will convert the atmosphere to oxygen- then TADAA!

>>2008085
Ok. What other ways can we create mass affects beyond mars' crust to get that iron already there to start spinning and not to lose its magnetosphere again? It is beyond our reach as of yet. Maybe 200yrs in the future

>>2008133
Durp solar wind plays push it somewhere else patrick all over your nascent atmosphere.

>>2008135
Simple. We drill down into Mars' core with a drillship made out of material that strengthens as more pressure is put on it, and generates electricity from heat. And then we'll explode a whole bunch of nukes and make it spin again.

>>2008105
>Implying Mars have an atmosphere at all.

>Implying Mars have an atmosphere at all.

I never implied that.

>>2008061
Actually, try Uranium. Earth is still very warm inside thanks to a very small Uranium core inside of the molten Iron core. A little radiation goes a looong way, man. Want to bring Mars back to life? Gotta refuel the core!

>>2008119
Making venus habitale for us is more sensible the way i think it. If we find some way to lose the atmospheric pressure to near something very very close to earth and deflecting some of the suns power, Plant some mocrobacterial shit there then we might create an atmosphere

>>2008147

Thanks for the inspiration. I like proving people wrong.

Does /sci/ agree with my water level? I think it gives the close to the greatest amount of shoreline.

It also looks good.

Wtf am I looking at?

>>2008266
Mars with water.

>>2008201
Would you like to join my government?

>>2008266
>>2008269

Exactly. Unfortunately, due to Mar's topological weirdness, the northern hemisphere ends up mostly underwater.

>>Mars with water.

Where are you getting this water from?

>>2008282
> Made using NASA heightmaps.

Basically, all land below a certain altitude I turned to water. It should be *almost* accurately how Mars would look with (this much) water.

>>2008282
Fantasyland. It's still an interesting way to point out the sharp topoligical differences between the Earth and Mars.

>>2008295
It's not fantasy. It's altitude-based.

>>2008300
He was asking where the water would come from. I told him that it came from nowhere. To actually add the millions of km3 of water that are present in that picture would require...

Well, crashing Europa into it would be a fair start.

>>2008315
Yeah, I misunderstood. I forget what altitude I based it on, but it would, of course, be a tremendous amount of water.

One of the most feasible ways of freeing up water on the planet is to get some cold-thriving black algae growing on the polar ice. This would warm the planet poles-first.

Also comets

>>2008352
You're going to need damn near every comet we know about to even start to make oceans on Mars.

>>2008360
Lol no
>Liquid water cannot exist on the surface of Mars with its present low atmospheric pressure, except at the lowest elevations for short periods[11][12] but water ice is in no short supply, with two polar ice caps made largely of ice.[13] In March 2007, NASA announced that the volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 11 metres.

>>2008412
That's actually remarkably little compared with Earth, but still quite a lot.

>>2008431
It's enough so we don't have to worry about comets. Leave the Kuiper Belt for Venus.

Do you know in the video game franchise Halo, Mars is influenced and probably populated by Filipinos.

I got the schematics right here!

We can/get very close to, one of the biggest hurtles is the issue of $$$$$$$$$$ and world cooperation

>>2008691
Don't worry I'm working on it.

>>2008027
There's enough magneticism on Mars to produce a magnetosphere, it just needs a huge slap to the face to stir up. This is where the whole "Smack Phobos into it" thing came from, since smacking Mars' moon into it is enough of an impact to get the magnetosphere working. It'll take years obviously, but still worth a shot. And even if it doesn't work, at least we can say we smacked a moon into a planet.

>>2008729
Phobos was suggested but I doubt it has enough mass to restart Mars' magnetic field. To crash something large enough would destroy mars' usefulness in CO2, water etc

>>2008008
>terraform the Moon

Seriosuly! Who started this shit? The Moon can't hold an atmosphere and will never hold an atmosphere. YOU HAVE TO BE A FUCKING BRAINLESS ASSHOLE TO NOT GET IT!!

>>2008781
>>2008781

Lets just nuke the damn thing until it can sustain life.

For terraforming Mars see this book:
http://books.google.com/books?id=BnPE37Ms5awC&lpg=PR2&pg=PR2#v=onepage&q&f=false

I doubt that we will see a terraformed mars in this century but we can set a colony there.

>>2008828
Radioactivity.
>>2008814
Wrong. it's just harder to terraform the moon. If you were to surround the moon with a artificial magnetic field and smacked enough comets into it you will have a fairly habitable moon.

>>2008843
PLEASE!!!! PLEASE!!!! GET A GUN AND SHOOT YOURSELF YOU ASSHOLE!!!

SINCE WHEN ARE NITROGEN AND OXYGEN MAGNETIC???????????? WHY DO YOU START TALKING ABOUT SHIT YOU ONLY HAVE READ COMICS ABOUT????????

Let's put some oxygen around a small rock with the strongest magnetic field mankind can produce and throw it into space!!! Let's see what happens!!

>>2008843
Terraforming the Moon!?!?!? Shut that asshole you have for a mouth!!!

>>2008856
Please tell me now, what strips gases away from gravitational sources?
>>2008863
Why so butthurt? I'm not advocating it as a near goal, but one that should start happening this millennium.

>>2008781
My dreams are ruined!

>>2008856
To be fair, oxygen really is magnetic...

>In normal triplet form, O2 molecules are paramagnetic. That is, they form a magnet in the presence of a magnetic field—because of the spin magnetic moments of the unpaired electrons in the molecule, and the negative exchange energy between neighboring O2 molecules. Liquid oxygen is attracted to a magnet to a sufficient extent that, in laboratory demonstrations, a bridge of liquid oxygen may be supported against its own weight between the poles of a powerful magnet.

But I doubt that there is a feasible way to terraform the Moon, It would be easier to make a really big city there inside a dome...

>>2008878
Don't worry, Mars can be terraformed and made fairly habitable. With the further distance from the sun, and it's three times thicker atmosphere (but not more pressurized, because lower gravity) means that getting sunburns and such will be easier. However solar flares may pose a large threat. In the near future (2100 - 2500) humanity will most likely have the technology to implement a planetary artificial magnetic field on Mars, right around the time when Mars becomes fully habitable (oxygen/nitrogen atmosphere, vast swathes of forests and grasslands)

>>2008872
Every small force you could imagine!

This millenium?????? You piece of shit! Stop talking about something you don't have the slightest idea about!! Fucking magnets crap doesn't make me rage but thius terraforming the Monn retardism is the only thing that really makes me rage everytime!!

Be it as small as you want! Each and every small force drives gas away from the Moon.

>>2008887
I still wanted to smack Phobos into it...

>>2008893
The moon has sufficient gravity to hold back its atmosphere if shielded from the solar wind. Any depletion in gases could easily be reproduced over the centuries.

>>2008898
That's still happening. North Martian Pole, 2047.

>>2008900
>Any depletion in gases

What's all the terraforming for if you have to replenish it every millennium?

>>2008903
I'm not finding much information on this. Elaborate please.

>>2008917
The amount of depletion is so little that it doesn't matter. Look at Venus. It has less gravity than Earth, no magnetic field, and 90x the air pressure of Earth.
The point of terraforming is having habitable planets with minimal to no maintenance.

>>2008929
I'm dedicating the next 30 years of my life to create a Manna-like society for scientists, artists, and all that wish to do research. A better society.
