Living on MarsOn the surface, the red planet’s freeze-dried world of rocks, ice, and dust looks like an unlikely place to plant a garden.

But rocks and minerals found by the Mars rovers show it must once have had warmer, habitable living conditions.

Now, using photo-realistic CGI visualizations, we’ll make a science fiction dream of Mars - a world of trees, rivers, and blue skies - a plausible future, bringing it to life after three-and-a-half billion years in a deep freeze.

The first and most important step in making Mars habitable is to warm it up, raising the average temperature 35 to 55 degrees Fahrenheit. (Average Mars temperature is about -81 degrees Fahrenheit.)

Bold concepts on how to warm up Mars range from detonating hydrogen bombs and guiding space rocks on a collision course with Mars to setting up little factories on the planet whose intent is to produce greenhouse gases.

Much of the new Mars would be an icy world, like summer above the Arctic Circle, with atmospheric pressure equivalent to a mountain twice the height of Mt. Everest.

The next step is turning Mars green and producing a breathable atmosphere, which will be a much longer and more difficult process.

Lichen and moss, which thrive on carbon dioxide, will be the first imports of plant life from Earth, perhaps 50 to 100 years after warming begins. They build soil, create more nutrients and pave the way for grass and woody shrubs.

Once established, Martian forests will spread on their own, improving the soil and the atmosphere, creating a livable world for more than just plants.

It could take 100,000 years for trees to transform an icy blue Mars with a carbon dioxide atmosphere into a warm, green planet with enough oxygen for humans to breathe.

A fully terraformed Mars may never be as warm and wet as Earth because it’s too small and too far from the sun. Low elevations where the atmosphere is thicker and regions near the equator will be the warmest.

  1. Ha ha. If you're lucky enough to read my comment, don't waste your time on... *alternative fuel* wink wink.
    Just from the summary, you know it does NOT address the main problem with Mars:
    it's NOT low temperatures
    it's NOT low atmospheric pressure
    it's NOT atmosphere composition (either now or future, doesn't matter)
    it's NOT scarcity of water
    it's NOT whatever irrelevant problems the filmers (sic) address

    The problem with Mars is NO MAGNETIC FIELD!

    There's no solution to that with current (read "up to 100 000 years from now), so calm down and eat your cookies.

    Hear that, musky guy?

  2. Why are we moving to mars when life is perfect here?

    1. Not really perfect because there are too many of the rest of us ;). But good point. Mars is useless

  3. It is high time the planet should mobilise its financial resources in terraforming other planets, not for wars and nuclear weapons! We seem to forget how small we are in the universe!

    1. Better, more harmonious AND realistic idea:
      Since Mars is no place to live and will NEVER be, why don't those who want to have a piece of each other go on mars and have at it there lol?

  4. How are they going to build a dome? Wouldn't gravity make it impossible for the construction materials to stick together?

    1. ,,,
      And yet, you probably garduated highschool.
      You're sweet.
      but it's sad ha ha

  5. Perhaps they should also be sending people that have already adapted to thin oxygen where other people develop hypoxia and continue the evolution of these people while working on planting moss from the artic ect to attempt to build a more friendly environment there.
    Indigenous highlanders living in the Andean Altiplano in South America, in the Tibetan Plateau in Asia, and at the highest elevations of the Ethiopian Highlands in east Africa have evolved three distinctly different biological adaptations for surviving in the oxygen-thin air found at high altitude.

    1. Elevation. You fly at altitude, you live at elevation.

    2. Haha
      Why do you want to kill people?!
      Go back to school.
      Start with kindergarten.
      To be on the safe side ha ha.

  6. How do you eat, and actaully live on mars though?

  7. how would we handle radiation problems?

    1. They have no answer to that.
      And thus, obviously, no atmosphere either

  8. Exploring Mars for the purpose of human colonization is the smartest thing we can do. In many ways. It is said, that we should be a multi-planet species. It makes sense, if we rely on just our planet, what happens when that day comes where, we've used up all of our resources and have become over-populated? instead of just waiting for that day to come, which, China already faces, we should just spread out. Let people decide whether or not they wish to become citizens elsewhere. Be it, a floating city in space, or a colony on the moon/ mars. Think about how many jobs it would create anyway. It would be reminiscent to the day the New World was discovered, but on a MUCH larger scale.

  9. the video ain't working

  10. The sky is already blue and the soil is not very red. it's more tan, like the Arizona desert.

  11. Terraforming mars is just a mindplay, would be a cute daydream or topic of conversation when you're really bored if not for the fact that current precious resources are beeing invested into it's exploration, just becouse the media puts accent on this red chunk of rock. Sure, life might have existed there, but sending robots there to check should suffice.

    In my opinion, the moon and overcomming our surrounding radiation belt should be our main focus space-exploration wise. Would be logical to take "small" but ferm steps considering our resources are limited.

    If exploring all of earth's undiscovered species is not mentaly satisfying enough, and really want to look for life or signs of extinction/formation of it in our solar sistem, then my bet would be on Europa rather then Mars.

    However, penetrating Titan's atmosphere will grant us accces to oceans of fuel, and would improve our chances to succesfully thrive and explore in more detail the above mentioned (provided no real alternative energy solution is found).

    Perhaps if we survive as species long enough, and catch the sun's expansion, earth would become too hot, and the new goldielocks zone would be set around Mars (perhaps it happend in the past?). Nice and optimistic scenarios to think of :)

    Or, if you really want to go wild about it, why not adopt Arthur C. Clarke's ideea and transform Jupiter into our second sun, and thus forming an artificial binary solar sistem and in turn create more life sustaining planets?

    I think of such things every now and then, but each time I do it, I can't help but amuse myself of how limitless human arrogance and ignorance is.

    1. gee, make a documentary or something

    2. by that time we will move earth and terraformed venus into the new goldielock zone and use mars as a giant greenhouse to grow our food =D

    3. Terraforming is plausible and possible. Think of the things people said were impossible 100 years ago. Today, they are everyday things we use.
      Terraforming a planet is a major task, but technology is fast approaching a point where it will be possible. The only limitations will be who finances it.

  12. good show thx

  13. my name is Kendon Ares, I am a descendant of the first colonists of this world who all took the same surname. It is 2255 and I am 26 yrs old (earth) and I am 4.31 meters tall, due to the lower gravity. I was fortunate enough to survive my birth as my mother was also native-born and her pulmonary system was adapted (so many of the new-arrivals do not deliver). My chest size is 75 cm because of the atmospheric pressure and my beagle stands at 36 cm. If I went to earth, I would collapse in pain and probably die. Welcome to terraformed Mars. We are a new species.

    1. Well said @dlwunz.

  14. glad they finally mentioned the lack of geothermic activity didn't think they would get to it. wander if they could use haarp to kick start it and cold fusion labs once that gets off they groud could produce oxygen faster

  15. @ Tommy Gunz Sorry but we really would be better off not curing cancer... can you imagine the population if everyone lived to 100...just insane...we need to die a natural death and go meet Jesus or Ahlah ...that is the natural course of life!

    1. we ppl can also live to 200 and somthing

  16. In respect to the microbes as well we should watch to see if there is life and use it as a STUDY tool to figure out our own genesis secrets. A 2nd genesis could solve cancer.

  17. Well its all well and good, but without a magnetosphere mars would continue to lose its atmosphere. Not to mention what would happen to us in a solar storm if we were on the planet.

  18. I don't agree that we should leave Mars to the "Martians". We don't have any "responsibility" towards microbes, for crying out loud. Just because they have the potential to evolve into something with intelligence over millions of years, doesn't make them sacred.

  19. What a waste of taxpayers money.
    Who the hell wants to live on Mars?
    The scientists say the world will end in 2012. Anyways can we really trust what they are saying here.
    They have to invent something to take government money.
    Who cares if the human race will be wiped out in the future?
    They can't fix earth and are worried about Mars.
    The excuse that they will mine minerals on Mars.
    If they do fix Mars; the only ones that would live there would be the rich, and the politicians to escape the destruction they did to earth.

    1. Clearly you don't know much about the lack of resources on planet Earth, the overpopulation issue that's going to be a serious issue with all the problems that will come from that, and how space exploration costs peanuts in comparison to wars. But do carry on.

  20. @Waldo; Hang in there man! Go get it done and come back for some more intellectual slap-fighting here on topdocs.
    @Achems; Me too, I have a well established love hate relationship with humanity. Some say it is an unhealthy relationship so I got a dog. Nothin but love there.

  21. @Waldo
    Good luck with your major, hope everything falls into place for ya.

    @420 Vision
    Earths oceans were once red with iron oxide as well. It should have time to settle and be buried by a few layers of sediment in the time scale they are looking at from beginning of the project to actual habitation and seeding of animal life.

    @ Reasons Voice

    ~ Ed the Sock (MuchMusic)~

  22. we should be flying by now, instead of killing each other, over and over.

  23. If we could terraform Mars into an Earth like place there still would be one big problem preventing the onset and sustainability of life,.. iron oxide(rust). This oxidation product which gives Mars it's red color would be impossible to control leaching out of the surface rocks into the new waters turning them blood red and highly toxic,..

    Iron oxide is an enzyme inhibitor and the reason why few multicellular creatures can survive within rusty water.

    just a thought...

  24. @ Reasons voice

    I have no issue with gun ownership, under sensible conditions though. I have issue with the exact lack of gun control in Arizona, and that they are pushing for even less control. Besides, I differ with Brewer on a host of issues, but thats for another day.

    I am sure I will be back. I am being overly dramatic cause I am stressed about other things. I just need to lay low for awhile and get some home work done. Thanks all, peace.

  25. @RV:

    You got that right, sometimes I actually hate people, well for a while anyway. (LOL)

  26. @ Miau

    I took the test, and it recommended the job I left to go to school, computer programming- that's incouraging?! Actually I worked in service for Motorola, supporting network equiptment, for like eight years before school (boring). It also recommended engineering so I can look into that more I guess. Thaks again- Oh, it says i am a INTJ type as well, what does that mean? Nevermind, we are way off topic. I'll look it up.

  27. @Achems just did that test and am an "IMFJ" type. A good test but flawed as all tests are by limitations and generalities. For instance I would probably be less introverted if the outside world wasn't full of imbeciles. LOL

  28. @Waldo; I truely hope that you do not leave the site. You are one of my favorite commenters. You do have the Jan brewer thing wrong though. In fact Gabby herself voted in favor of protecting second ammendment rights on multiple occasions. No sure as to any connection between the two individuals though. It's just that you do see the destructive diviciveness of government but then support it with that statement. The attack and manipulation of this issue orrigionated from the left and the anti gun movement, with no regard for the victims stance on the issue.
    Any-who.. Don't go Waldo need ya here. As for the world comming together ever; I have my doubts. Even if it were a time of crisis (perhaps especially in time of crisis). Look at the events that follow natural disaster or political upheaval. Looting, Rape, Murder, and total abandonement of civilized behavior. One man who has known a shop owner his whole life may kill that shopkeeper after an earthquake over something as simple as the last can of beans. I am actually glad so many docs. and movies are being made about "end of days scenarios" since maybe by the time one comess people will be desensitized and apathetic enough not to eat eachother like rats on a sinking ship.

  29. Mian:

    Good test, took it years back, re-did it just now, again says am a strong "INTJ" type.

  30. @ achem, ProudinUS, and Miau

    Once again, you guys are right. I suppose I just need a break. To some of us posting here and discussing opinions in other formats and venues is something we do in passing, it really doesn't matter. But for people like me that have dedicated their life to rational open discussion the insults and closed minded rhetoric can get very discouraging at times. I am sure I will eventually see a comment or documentary that I feel I must say something about, that is my nature. But for now I need a break, besides the spring quarter just started and I am swamped.

    This is my last quarter at my current school, then I tranferr to a much larger and more intense institution. I can't believe I am half way through my second round at college, I obtained a degree in theology and western civs right after highschool, but found the degrees pretty much useless. I have to figure out what exactly I am majoring in this quarter as well. I have been taking required courses so far, but it is time to declare a major and start taking courses geared toward that degree specifically. I have shifted between physics, mechanical engineering, and archaeology. But I am still undecided really, I want to do what I love but also have a practicle degree for my area. Any way the stress is starting to boil over into my comments here and conversations with people I know. So I am going to chill for awhile, but I am sure I will be back sooner or later. Thanks for the words of encouragement, they were much needed this morning.

  31. @Waldo:

    Everybody learns from all the viewpoints on this site, I have learned a lot of stuff from you.

    Nobody is giving you the gears Waldo, unless you let them, nobody is picking on you.

    So are you going to go away in defeat? Shame! Com'on man, pick yourself up!

  32. @Waldo
    I understand. I also see this in every public debate. The only reason that I can think of that would explain it - it may be some sort of remnant in our genes - need to compete and dominate and to preserve ourselves. But I believe in order to move our society forward we should abandon such approach as it only creates chaos and hatred. It is the opposite of cooperation and dignity.
    Yes, don't let them get you down. :) I find your posts inspiring.

  33. @Waldo

    Hey man. Don't let them get you down .Some of us learn alot from your comments!

  34. @ MrMajestik

    No offense mate, but I am done commenting on this site. I can't stand the "I am smarter than you" attitude that runs rampant, not to mention the petty insults from people I would'nt wipe my arse with. I am not referring to you in any way, its all about things in the past and on other threads. And in reality its not this site alone, every site like this one is the same. You go on and post your opinion- for what. So people can insult you and mistake your point and trip all over themselves trying to look more intelligent than the next guy. I am done. Peace!

  35. Miau seems to not realise that it is GRAVITY which holds an atmosphere to it's planet. The magnetosphere protects from cosmic rays. LOL Anyways,Assuming we could pull this off, it wouldn't last, because mars has no tectonic processes. We COULD however use kinetic energy and impact mars(as some scientists theorise)with a very large, dense missile. A solid mass, after orbiting the solar system gaining EXTREME velocity, could then impact mars at just the right angle, and in the opposing direction of it's axis, and thus "gouge" mars, much as the Earth was in the cataclysm which formed the moon, and ignite the geothermal reaction, just as it did here, billions of years ago. In essence,create a planetwide cataclysm and let the dust settle before terraforming begins, of course the sum of mass x velocity required to simulate the impact of a planet sized object may be beyond our industrial, technological, and cooperative capabilities.

  36. @ MrMajestik

    Sure, I would like to, but I have been reprimanded a few times lately for getting off topic, in a polite enough way of course. So it would have to be under a documentary that was about that type of thing. Cheers!

  37. @ waldo… Sorry, I did not mean to insinuate that you were suggesting I was an idi0t. I was just making the point that my head was not buried in the sand. I figured you would catch my point, we I do, the night sky on a moonlight night is more meaningful than ever stepping into a church. Clearly, you seem much more capable of abstract thought than our friend, I wish “MarsWayCool” would join this thread! Well I think if you want to discuss more existential concepts and theories we should watch some other documentaries & we should discuss!

  39. @Wayne
    Those factories wouldn't be there to exploit any materials. They would be specifically built to pump out fluorocarbons to cause global warming.

    @everyone saying save earth first and forget about mars...
    The process of invention is driven by need. By looking at mars and saying we NEED this NOW, we may end up solving the problems of earth entirely with the same research and technology.
    Even if we don't implement these technologies in the mars environment for hundreds of years, they may make a definite impact here, today.

  40. As a matter of fact I suppose the stars and other planets could exist without Earth, but we could and would not exist without them, nor would the Earth as we know it- since after all it is only the "Earth" because we say it is. But now we are getting into the existential question of existance, now that is abstract.

  41. @ MrMajestik

    I never meant to insinuate you were an id10t, after all I was the one who didn't get it. Abstract(?), not really. Though if we want to get really specific we owe as much to the stars and planets as we do the Earth. None of the above could exist without the others, and niether would we.

  42. Mulitnational corporations using government money to set up factories on Mars with no environment laws against CO2 emissions and lax workers rights might be possible if there are marketable resources available.
    To get things started, the engines of the spacecraft that land on Mars would have to be easily convertable to power plants as well as habitats using, in large part, local resources

  43. Excuse me... "WayCool" label saved ... typo

  44. @ Waldo I suppose it is the paradox between his name and the obviously fatalistic paradigm he has? Wouldn't you would think a guy who owes EVERYTHING to this planet would not have his "cool" label saver for something a little closer to home??? Perhaps that is too abstract for you? I agree the earth and people will continue on I am not an idi0t, but I wonder how hard it will be for us to maintain this consumptive nature of modern man? So I supposed to answer your question directly, it was probably the tone of apathy that lead to the comment!

  45. @ MrMajestik

    I don't get it, what is so cavalier about pointing out that he thinks the earth will be destroyed in a few hundred years? I am not sure I agree, I think earth will be fine, its man that very well may be destroyed. But, I don't see his comment as cavalier. Can you explain what is so bold about his statement?

  46. O.K. they clearly do address the issue of having no protection from cosmic influences that would strip the atmosphere, I can't believe so many people either missed it or didn't watch the whole doc. They say that it would take tens of thousands of years for it to have any significant effect on the atmosphere they want to create. Of course that begs the question, what would we do about cosmic radiation, especially from sun storms? These storms could destroy all electrical devices and give anyone not protected a massive dose of radiation. There is constant cosmic radiation raining down on all planets in the solar system, so a storm would be a concentrated dose but we would have a constant exposure issue as well. A ozone layer would be part of the atmosphere they want to create. This would remove some UV radiation, but is not enough protection all on its own.

    One thing we all seem to be overlooking however is that Mars does still have a weak magnetic field as well as a recently mapped ionosphere which does reflect some solar radiation. The the MARSIS mission mapped this ionosphere and found that in several places the magnetic field lines are running perpendicular to the surface of Mars, much like our North and South poles. In these regions one would expect to see auroras at times, like we have here on earth. Here is a breakdown of our ionosphere and what it absorbs:

    "The ionosphere is broken down into the D, E and F regions. The breakdown is based on what wavelength of solar radiation is absorbed in that region most frequently.

    The D region is the lowest in altitude, though it absorbs the most energetic radiation, hard x-rays. The D region doesn't have a definite starting and stopping point, but includes the ionization that occurs below about 90km.

    The E region peaks at about 105km. It absorbs soft x-rays.

    The F region starts around 105km and has a maximum around 600km. It is the highest of all of the regions. Extreme ultra-violet radiation (EUV) is absorbed there."

    The MARSIS mission has mapped the day side of Mars and is moving to the dark side to see what it may, in fact I think it has mapped both hemispheres by now. Though they say the ionosphere is not as thick nor as effective as ours here on Earth it does exist and so does a very weak magnetic field. In my opinion we should be able to create our own localized magnetic fields around certain areas as well. Here is what wikipedia has to say on the subject:

    "The Mars Odyssey spacecraft carried an instrument, the Mars Radiation Environment Experiment (MARIE), to measure the dangers to humans. MARIE found that radiation levels in orbit above Mars are 2.5 times higher than at the International Space Station. Average doses were about 22 millirads per day (220 micrograys per day or 0.08 gray per year.)[7] A three year exposure to such levels would be close to the safety limits currently adopted by NASA. Levels at the Martian surface would be somewhat lower and might vary significantly at different locations depending on altitude and local magnetic fields."

    As you can see they say that even in orbit, which exposes you to more than being on the surface, you can last about three years before the dosage gets too high. Taking that into consideration and the fact that we can create local magnetic fields in some areas, limit time outside, and use shielding in our buildings and homes- I would say this issue does not kill the idea of colonizing the planet at all. In my opinion we should give NASA more credit than what we do at times, they have achieved some amazing things. Yes, they suffer from bureaucracy issues, and ego gets in the way of good sound science at times, but they have still managed to do things that no other agency or entity on this planet has ever achieved.

  47. @ MarsWayCool Sad comment...I wish your name was "EarthWayCool!" Perhaps you would not be so caviler in your comments???

  48. @ Miau

    No, I haven't stopped trying to organize effective resistance to the status qou. I must admit that I am no where near as optimistic about its success as I used to be though. Right now I am organizing a group in my area under the "No Labels" slogan. It is a movement that seeks to do away with ideology and labels and have each politician judge each issue on its own merits, with no preconcieved ideas about how to handle things. We also want each voter to analyze each candidate on their own merits and record and not simply vote for someone because they are the candidate for the party you support.

    Lately we have all become aware of the violence that is threatening our democratic (well, its suppose to be democratic anyway) system. The shootings in Arizona have brought the violence issue to the fore front of almost everyones minds. I have to say I have been very disapointed in the blatant and disgusting attempts by certain peoples to use this for political gain, while at the same time refusing to take any responsibility for the hate filled unprodcutive partisanship that has devided our politicians and citizens into seperate ideological camps.

    Jan Brewer for instance should be ashamed of herself, as well as removed from office as soon as possible. How dare she call herself Gabby's friend and at the same time support the very gun laws that help to facilitate the shooting as well as seek to fill Gabby's seat with a member of the opposite party. She is not the only culprit, Palin has used this issue for her own gain as well, trying to portray herslef as a victim while we have people dead and in the hospital that were actually shot is disgusting. Her and the entire right's refusal to accept any blame is also ridiculous. This isolated incident may very well have had nothing to do with their hate filled violent rhetoric, but surely we can all agree that it creates an atmosphere in which eventually someone will take their second amendment referrences seriousely. What then? It will be too late to take it back. The truth is these people do not care, as long as they enflame their base and gain a few political points they would put their own children at risk.

    If man is to ever achieve goals like those portrayed in this documentary he must first learn not to charge the atmosphere with violent rhetoric and exaggeration against opponents. He must learn that no one group nor political party can own the world and have it all their way, that is impossible. The key to success is always cooperation, and seeing the problems at hand from as many different perspectives as possible. Right now we seem to have both sides pushing for extreme outcomes, one wanting to grow government to an unusual and no doubt unproductive size and regulate everything to death, the other wanting to remove all regulations and hand the well being of the world over to profiteers and religious exlusionists who would do away with science and reason and deny the obvious to make another dollar. I truly believe sanity and our continued survival lies in the middle with moderation that comes about by having "No Labels".

    As far as the terraforming issue of having no magnetic shielding, surely these guys thought of that. I can't beleive they would leave out such an central issue to the problem at hand. I have yet to watch the entire doc. so I will wait to see if they address this issue before the end somehow. I had always imagined a terraformed planet having huge bubbles of some sort and all life and activity taking place inside such bubbles. Thats the way all the futurists have drawn the terraformed land scape so maybe thats where I got the image in my head. When one thinks about it though that would be a enormouse engineering challenge, to build a bubble large enough that would never collapse or run the risk of being shattered by debris or micro meteorites from a translucent material. I will post again after watching all of the doc.

  49. Within a few hundred years Earth will be destroyed.

  50. Why not fix our own planet first before destroying Mars?

  51. @ Waldo. It is 'sister' in my case. :) But I understand what you are saying. Imagine this picture: 5 wingless birds sit on a branch very very very high up in the tree. I am one of them. The remaining four keep jumping around, fighting, the branch started cracking a bit and it is just a matter of time before it breaks and we all fall down. I may try to explain to them that their jumping around and fighting will only kills us all in the end but they are so consumed in their activity that they don't listen. And so I am just sitting there, knowing, and waiting for the inevitable.
    This is so terribly frustrating! You are right - everyone of us has their own perspective and truth. But I really wonder - what will it take for the remaining four wingless birds to realise we really need to calm down and be nice to each other and work together?
    I keep meeting (mainly online) people who see the status quo like me or you (or pretty close) and they just don't know what to do about it. So many people See and want to 'change the world' but they don't know what action to take, how to contribute. As if they were waiting for some sort of movement or leader to follow and support.
    What about you? Have you stopped being an activist? It sounded like that.

  52. I agree with most of comments that I have read. Why don't we do something in this planet, instead of waisting any more with impossible dreams that only very few may benefit in the long term. First fix the problems at home and teach the heads (with no brains) of governments, how we could live in peace (I know this is my impossible dream).

  53. How arrogant is this scientist? One human being, one idea and some numpties would welcome this research. How dare he and his ilk play supreme being.
    Who is to say life didn`t start on Mars and came from there to earth? Humans have and are destroying this planet.

  54. wow such a pessimistic bunch! you guys must be socialist!

    this is how capitalist think!.. as long as there's money to be made in this project or anything nothing is impossible as long as the current science allow it..

    also you guys belittle the need to have 2 homes.. the reason scientist and engineer are pushing this because they want to prevent the only thing that can extict such a top species as us and that is a global disaster on are one planet. so obviously the ultimate sure solution is to have two planet dah.., and its to early to criticise it. this will not happen in our generation so cool down your acting like the unknowlegable 19century folks who criticise tesla.. the only job of are generation is just to study mars, are great(2x) grandchind will do the terra thing..

  55. How about we focus on solving our own climate/ terra issues here first before we fantasize about heading off to Mars. If we can't get it right at home why would we even begin to think we could do it elsewhere? Our global society is killing this planet and species are going extinct at a rate of 200 per day. We are growing in population at a rate that is entirely unsustainable and our planets carrying capacity is maxed out. We already use 60 % of the words fresh water supply for our own species survival, that doesn't leave much to go around for the others we share this planet with. Our actions are directly and indirectly responsible for the need to Terraform another planet because we have exhausted our own. While its true that will live to see the day when we need to leave and colonize new territory, it's irrational to propose that solution when we know it's unsustainable to begin with. Lets stop funding programs that cease to recognize and deal with the problems at hand, lets cut funding to anything that doesn't address reality. We humans need a habitat, we can't escape that basic nessesity so lets make our decisions based on the continuation and health of that habitat rather than just finding another one. It's all just like drilling for oil, instead of breaking our addiction to a limited resource thats destroying our planet and health we just look for more of it, all the while knowing we are on the clock and someday it will run out.

  56. hmmmm
    freeze dried rock with no atmosphere... or beautiful planet that provides everything we need if we are not greedy?
    i think i'll take my chances here!!

  57. "when it is time to move to another planet"
    anyone else find the chipper upbeat tone a little disturbing?

  58. @ Miau

    I feel your pain and confusion brother, I have asked those same questions many times. But, after several years of organizing different political movements and working on different campaigns I have come to find that there is no consensus out there. You would think that most of your ideas and objections are based in common sense, and therefore must also be the concerns and ideas of the majority. Not so, reality appears much different to everyone due to perception being filtered by our belief systems. In the end we all live in the same world facing the same issues, but that is not what you would think if you sat down one thousand people and asked them to decribe the state of things as they see it. You would get one thousand different takes on the world state and where it is taking us.

    I used to get angry, and still do often, and say so and so is just st*pid, and so and so refuses to see the truth because they want to believe this or that. But I am starting to realize that it is not a consciouse effort by people to see things the way they do. They may be very smart, or very honest with themselves and others, and still they will see things sometimes the very opposite of what I would say is the truth or the common sense solution.

    The only answer I can see is for everyone to realize this, and try hard to see things from one anothers perspective, there by gaining the truth that the other may see as well as our own truth. To stop segregating ourselves into different ideologies and belief systems and start working together no matter what our differences, so we can understand and put together all of the percieved problems and preposed solutions.

    This really doesn't make it any easier however to come to any certain decision. To truly have consensus everyone would have to settle on one truth, and therefore one solution. I don't think that will ever happen. This I fear will be the doom of our species, that we are able to percieve and act, just not as one large effective unit, which is what it will take to fix the global problems we are facing. Up until now man has faced individual problems, community problems, and even national problems. But, for the first time in history, man is faced with global problems, and I don't think he is capable yet of dealing with them. I suppose we let our technology get far ahead of our not yet fully evolved cognitive abilities.

  59. For grey area: Why do you think gravity would pose a problem ? This documentary states that indeed, because of the lower gravity, Mars will eventually loose it's human formed atmosphere, but it will be habitable until then. Besides not being able to keep it's atmosphere, do you know more about the role of gravity on maintaining a life-friendly planet ?

    Besides that, people with weight problems will have a reason to be happier, since they will weigh less, living on Mars :)

  60. yes humans can make this happen . only together. essentialy trying to give life to a dead planet, nasa x 1000000. it would really be something... if it worked i prophesise mars would thrive again, people who come will live and grow differently, martian life will grow, another earth is born and the it will begin the NEW world. new religions , new wars , new problems, then we will never stop, when mars gets bad or is doomed our bodys will have evolved and our technology and ability as well allllowing space travel and new human colonization becuz man is the most brilliant creation of life , but also the most wretched thing simultaneously.
    Did i say it will take thousands of years sorry i meant tens of thousands at least man!! lol . actually sratch everything i just wrote well have killed eachother off by the time we even get close to this .

  61. Perhaps people will learn to cooperate on a global scale if humanity faces extinction here on Earth. We may not mobilize right now, as we are all on a race to get rich consuming and deteriorating the planet, but sometime in the future, when these resources get scarce, we would wake up.

    Nevertheless, we wouldn't have a magnetic field like Earth to redirect the solar radiation to the poles, since Mars doesn't have the iron core to generate this field. I guess that would be ... a problem ?!

  62. saw this doc a while ago and i love the idea. the theory of terraforming is sound . this is all theory. they dont know what is in mars core, it could be like earths but stopped working and the iron is solid , if that was then there thinking maybe the bombs and pollution will spark something, then churning ignites , volcanoes start erupting , possible land movement , this will heat the planet . all this activity will cause magnetism in the poles, atmosphere will return , water will appear. but the gravity is the big problem. will ther miraculously some how the planet grow , gain more? and the technology needed to pull this $hit off is mind boggling . Man will need thousands of years technological advacment to make this happen so we better get off our a$$es to play god like this. im talking man-made gravity machines and spacecraft are being production line like your new lexus 4x4. earth should be near collapse , or by some miracle still surviving , and resources running dead low.

  63. @ Miau I know isn't it silly how some segments of our society believe that at sometime there will be a one world government... LMFAO... Like that would ever happen =))) We can't each other to save our collective planet, but somehow everyone but one is gonna agree to loose their sovereignty. You might want to check out "Collapse," great doc but not on here yet... will be eventually I am sure ...

  64. Here's a thought. People born on Mars would end up being taller due to less pull from the planet day by day. This could mean their bones would be too fragile to live on Earth yet people on Earth could come to Mars quite easily.

  65. I am wondering - if there is so many people who see the point (take the money humans put into weapons --> destroying ourselves and invest them into creating instead of destructing) how is it then possible we are still going down the drain?
    Sometimes I feel like an alien..... I am not getting this. Why cannot reason win for once over stupidity? Why cannot politicians stop playing their silly games (perhaps also being puppets of corporations, dont know) and do something positive, make a difference in a good way, cooperate, get nations really work together.... Why it always has to be money that matters more than happiness, human life and dignity?
    Baaah, I think I just watch too much Star Trek. :( :@ And it is also late. I better go to sleep.

  66. So let me see if I get this right... science, technology, and TRILLIONS of dollars can make an unlivable planet as beautiful as earth, but we can't keep sustain a planet that is already a living one? W T F is wrong with your rational people? Sorry but I think this is propaganda to increase funding to NASA... there is just a big disconnect in logic here! And to think life gets easier to produce the further you get away from the Sun just doesn't make sense. Stop the delusion and just stop thinking you need a Hummer and a bunch of plastic sh!t from China.

  67. @Achems Razor
    You're funny. Younger maybe, average lifespan aprox 40 yrs instead of 80 yrs. Although I wouldn't mind a chance to be in my early 20's again. Woo Hoo!

    Completely agree ... so much misguided time, effort, money that would be much better focused on our present home, Earth. It is nothing less than frustrating when our collective resources are wasted on ridiculous endeavors such as this.

  69. One good thing, according to universal time scale you would be younger on Mars.

    One year on Mars is 687 earth days, therefore a person who was born in 1981, 30 years old, would be only 15.5 years old on Mars, fountain of youth? since time is relative to the observer, maybe humans can adapt on Mars time and live longer, yes? just a thought, (LOL)

  70. That definitely looks interesting! :) I will try to get to those books and read them. :)

  71. Read the Mars Trilogy by Kim Stanley Robinson, a novel about the terraforming of Mars in the near future, from the arrival and struggle of the first humans there to the clash of cultures between new colonists and the first generations of Mars natives. So captivating I had to read it twice ;)

  72. @ron - can you explain what you understand under 'non-linear' universe please? I've been pondering this topic for some time now....

  73. watch and finish the doc first before you guys comment... you'll look st****!

  74. No need to create an atmosphere on MARS, as it is not required for the post-humans who will be no more a biologic being, at least at the time frame MAN(non/partly biological) reaches the planet!!

  75. Linear thinking in a non-linear universe. Pointless.

  76. @Blood Eyes,

    Dude, our planet isn't dying!
    from the 4.5 billion years of its existence its been through a lot worse then the influence of humans...

    We might end up making the planet inhabitable for humans if we continue on our current trend which might lead to the extinction of our race,
    But when we are gone, the planet will recover in a 1 or 2 thousand years at most, which for the planets life-cycle is like a few heart beats.

    So don't worry the planet is fine.

  77. I personaly think this documentary is more like a dream than reality.

    Lets face it if we dont take care of our planet first, I really do believe we will be extinct first before we can build Mars our second planet.


  78. a few things why this is a waste:

    1.No magnetic feild strong enough to keep atmosphere and to protect from radiation.
    2.Mars has a moon that has a decaying orbit that will soon slam into Mars " a life ending impact"
    3.wasting gagillions of $$$ when problems on earth should and can be solved first to allow life to continue here.
    4. We have the privilage to live on earth yet we cannot even BALANCE sustainable life here first.lets solve one major problem first before we CREATE another.
    5. that scientist McKAy needs a smack in the head and should spend his time "dreaming" up ways to fix the earth instead of daydreaming of hanging out with little green men on Mars!

  79. What about radioactivity? Mars doesnt have spinning core, so they would have to reignite it to create electro magnetic shield against suns radioactive rays.

  80. Why not terraforming earth deserts first?
    Why create jungles that produce food?
    Why build high tech green cities inside?
    Can it be the first steep before Mars?

  81. I don't understand this documentary... why are they 'promoting' creating atmosphere on Mars if they know (they must know) that it will be blown away by solar wind since there is no magnetic field to protect the planet? Weird....

  82. The hard topic is not how to "pollute" Mars to make it terraformed. The problems are mostly: magnetic field (there is very weak on Mars) which means that the atmosphere on Mars will be at least fragile.

  83. As I understand it, Mars is a dead planet today because its core has cooled and its electromagnetic field has dissipated leaving its atmosphere exposed to solar radiation. Without an electromagnetic field no new atmosphere will stick.

  84. I thought Mars was lacking the magnetosphere.... without it no atmosphere will ever 'stick' to the planet. :s Haven't finished watching though... maybe it is explained. :)

  85. I'm down to live on Mars, be the first to explore and inhabit mars

  86. I agree with Ron here. How can we acheive a task such as this if we don't even have the resources for our own planet? How can we pack up and go if we don't even have the material to build a "suit case". There would be to many passengers and not enough plane.World co-operation would deffinatly be needed.

  87. Yeah...we're doomed
    As an open-minded atheist I would just like to say: i sure hope reincarnation isn't true. I'm glad to live and die in the 21st century; killed by a car or cancer seems so much better then dieing with the rest of my species.

  88. They forgot about one important ingredient needed to make this happen, co-operation of all humans. It can't happen if we are over populated and fighting over less and less available resources so I have very little hope of this happening any time in the next 2000 years.

  89. won't see it within my life time though
