"If you had the power of geoengineering to terraform Mars into Earth, then you have the power of geoengineering to turn Earth back into Earth" - Neil Degrasse Tyson
It's not that simple, terraforming mars basically involves heating up the planet, be it for releasing CO2 or water from ice at the polar capes, by the means of global warming. You can do that by solar mirrors or simply nuke the planet and things should be okay in a few years span. But on earth the conditions are different , we are facing the problem of execssive global warming, here we donot have to increase the temperature but to reduce it , which is not that simple. It's easy to add energy to a closed system like earth but very difficult to extract from it in human life scale time span.
There just need to be less humans on Earth. That is the very basic issue humans have. We have overpopulated the planet. You cannot go live on Mars, it has no magnetic core to protect you from radiation. You can't heat up Mars any more than you can cool down Earth with mirrors blocking the sun. This is junk science.
The problem is not that we can not save earth the problem is we don't have enough space resources to outlive potential 10 - 12 billion people on earth one day all of water gas is going to run out and as the vedio said it is neither save to have just one planet to live ... The Mars mission is only viable option ..
That's called being a Commie....and there is nothing "Green" about Space Travel...it takes vast amounts of fuel to get out of Earth's gravitational field....
Harry Kuheim, space travel isn't as expensive as you might think, since most of it is just Hollywood. They've never left our atmosphere and gravity doesn't exist. We live in a contained environment. Unless you know of some science that shows a pressurized atmosphere existing next to a vacuum without a physical barrier. The Earth is motionless and flat. What do you think about the Arctic Lemming in the official image from Mars?
The problem with the terraforming or planetary engineering steps outlined in this video, in my humble opinion, is that they will likely take many hundreds of years - if not thousands - to materialize. We, humans, are an impatient species. We cannot properly implement 5-year plans, let alone hundreds. We rate a company's performance based on short-sighted quarterly results. We judge a person in the first 20 seconds of meeting him/her. Any feasible plan for terraforming will likely need to be completed in human 1-2 lifespans, if not less. That may be quite possible with the exponential growth in technology's prowess. I am no expert on this topic and admit that the speaker has much more knowledge than myself on this matter, but that's just my two cents on this.
We are already in the space -- and even almost in the "void" as they interpret it, -- they who talk talks like this... "Scientists" without any criteria for reality...
You are correct but if mankind is to change and evolve then we need to work for the future and for future generations. Our current short-term thinking is what is screwing up the Earth. Not nearly enough people care about the climate change to actually get up and do something about it because ultimately it is not relevant to our generation. If it takes 100's or thousands of years as I believe it will, changing our thinking now will increase the odds of the human race living to its potential. Current economic and political policies at the moment encourages selfishness, greed and self destruction. If Clinton had her way then WWIII would have been on the cards. Those political insiders who voted against her know this. We are at a crossroads, one that is bleak if we continue on as we are and the other perhaps providing some hope that the human race will continue on regardless of what happens on the Earth. I think this is why it will happen.

Yes, we will have a colony on Mars by 2200, which will grow to a population of 20 million. But unfortunately they will all parish in the year 2265 from a great disaster. Humans back on Earth will lose hope, and give up on space exploration. Chaos and panic will ensue due to this, overpopulation, and lack of resources. There will be a great global war in the 24th century which will wipe out all but one billion. But in 2396, those one billion will say "enough is enough" and create a new world parliament run by scientists, technologists and humanitarians; no longer will corrupt politicians, greedy businessmen or religious fanatics run our world governments and ruin our planet and species. The calendar will be reset to year 1 again. Many smaller nations do not agree on the new world totalitarian technocracy, and resist/rebel, opposing it directly and indirectly for the centuries to come. There is a new Dark Ages that lasts 1,000 years. In 3382 AD, a strange mutation will happen in the human brain. People will get a remarkable phenomenon referred to as hyper-vision or hyper-intuition. One after the other, man and women on Earth will acquire this new spiritual ability which will be an extremely powerful way of reaching ‘the great Spiritual Light’ and enable them to get ‘the Direct Knowledge.’ BETWEEN 3400 AND 4000 AD This period can be referred to as the new ‘Golden Age’ since the previous century was a kind of ‘dark age.’ There will be ‘the Universal Creators’ (instead of the Global Parliament) who will combine the qualities and abilities of philosophers, artists, scientists, mystics, and all the other ‘quality people’ on Earth. Now, everything will be free - clothes, houses, food, transportation, EVERYTHING! There will be no private property, and the only things which will matter to people are honor and a good reputation. Hurrah, finally! The technology and material standards of living will be unimportant, and people will care only about their emotional, mental and spiritual development. Self-improvement will be highly valued. One more thing is interesting here - in their whole life, people will work only two years! That will be between the age of 17 and 19. Can you even imagine this? At this period in the Earth’s history, the population of people will be less than a billion. This is probably why there will be an abundance of products for a decent living for everyone. Also, there will be very few laws in the society since there are no criminal intentions of individuals in this society (What for when they are all smart and have everything they need to be happy?). Actually, there will be only three kinds of laws: Those related to the 2-year working period. Those that arrange how traveling traffic and distribution of goods is done. Those that deal with the demographic stability of the population size, i.e. the general birth control. --Paul Amadeus Dienach, Chronicles from the Future
No matter what is done to try and terraform Mars, you would never be able to restore the magnetic field to shield the planet. Terraforming Mars is a huge pipe dream
Jo-Erland pointed it out but, the humore comes in when we talk of ANY plan to terraform Mars. We can't terraform a planet using ANY plan if the planet in question has no magnetic dynamo which creates a magnetosphere which protects the planet. Ozone is only one of MANY things that protect life on this planet and without the magnetosphere, the solar wind actually strips away the atmoshpere, molecule by molecule. Mars has no magmetosphere and so it cannot protect an atmosphere, even if we tried to build one. It's why it lost the majority of its atmosphere in the first place.
He skipped a step, you need to establish a magnetic field for Mars. Without that everything else is pointless. The good news is we have the tech to do that. It just requires a butt load of power.
We were told, humans over populated the earth. I'm just a truck driver and every time I drive states like Wyoming, South Dakota, North Dakota, Utah, Montana, Idaho, Oregon, Texas, Arizona, Nevada, Kansas, Colorado even Northern California Eastern California, you don't see buildings or town going through those places. I'm a truck driver and I know where can get stuck in traffic most. Cities and people are usually over populated by the oceans. My point is why do we plant trees in those empty open lands and spread out people.
Why are so many of these people talking about "once we've got a atmosphere, we put plants on the surface to turn CO2 into O2" as if thats a suitable solution? Wont the process of creating suitable levels of O2 (and more importantly, lower levels of CO2 as its usually not a lack of oxygen that suffocates you but too much CO2) take millions of years with plants? They're not superfactories or we'd solve the 0.005 % extra CO2 in earths atmosphere from global warming by simply planting one new forest on an empty patch of land. No. For this you need superfactories. One that we can't make yet or we'd place one here to solve global warming.
THE THICKER THE ATMOSPHERE , MORE SUITABLE FOR US TO LIVE. THEIR IS 98 PERCENT OF CO2 WHICH CONSISTS OF 78 PERCENT OF O2. WHAT WE NEED IS O2 AND THE REST IS EASY. I GUESS.
its more about having an atmosphere so construction and living is easier, you will be able to walk around with an oxygen tank. if we detonated some super powerful nukes over the poles it would do it
wouldnt take millions of years with plants, maybe a thousand but more likely a couple hundred. www.space.com/764-mars-habitable-inject-greenhouse-gas.html
The interior of Iceland is purported to be uninhabitable. But what about Mars? Obviously, Mars is even more uninhabitable because you can't even breath the air or survive outside without a pressurized suit!
Insanity can be expressed so rationally as to sound normal But it is insane to even think about "terraforming" mars. We need to fix the problems here created by materialism and rampant consumerism.
only 1 BIG PROBLEM - MARS has weak/non-existing magnetic core compared to Earth. It get's bombarded with solar wind, the reason it lost the atmosphere. Unless we can restart the magnetic core of the planet, you will not enjoy the outdoors ;-)
+tom maly Yes, that is true, and we won't be able cover the entire planet, at least with 21-century technology, which of course means that atmosphere will be lost slowly. However, that doesn't mean that you can't live outdoors, because you could build solar powered electomagnets that gives a magnetic field to every Martian city. In the thousands and thousands of years it will take for the atmosphere to dissappear after we create it, we can probably figure out how to shield the entire planet to give it a sustained magnetic field.
I'm happy that we are finally getting our buttocks out into space. I am sad that it happened so slowly, that I am unlikely to ever experience it myself, or even see a real colony established. Oh, time, how cruel you are.
When I was in high school, I has every expectation that, by now, the colonization of Luna would be well underway and that we'd have had expeditions to Mars. It should have happened, too.
@@stevenpilling5318 It's because the cold war was a time of competition between nations which led to rapid technological development. To bring that pace of development back, we need countries to challenge each other technologically. The rise of China might be of help to us, but if India and Russia could also chip in then we'd be on Mars in no time...
Interesting that he said it was a Tuesday. In India, Tuesday is called Mangal-vaar and in vedic astrology it is the day dedicated to/ruled over by the planet Mangal which is Mars.
I've often wondered (feel free to give me some input - I am curious), if it is not feasible to take some of our many nuclear weapons and "bomb" the north and south poles of Mars. There are no people there now. That would be a more productive use of nucear weapons, melt the dry ice, cause global warming. If people go there in 20 years, the atmosphere could be much more accomdating. There is little or no radiation in Hiroshima, Japan today. Radiation does dissipate. Could we use nuclear weapons in limited quantities to melt dry ice but not create an excessive amount of radiation on Mars?
Hi Trevor, The energy in an atom bomb is TINY compared to the energy from the Sun. The heat from an atom bomb radiates back into space, and soon is gone. However, if we can make Mars' atmosphere thicker, it will KEEP the heat from the sun longer. If we can make Mars darker, it will STAY warmer. If we add super green house gases then they will absorb 7,000 times more heat than CO2, and last for decades or centuries. I'm not saying that bombs are useless. "Clean Pipe Hydrogen Bombs" (which use deuterium and conventional explosives to set them off, rather than a fission bomb), could blow up nitrate beds on Mars and put back N2 into the air. That might be a good use for bombs. Or cracking rock to let a liquid aquifer come to the surface. There are several good books on Terraforming, the best is: "Terraforming: Engineering Planetary Environments", by Martin J. Fogg, to read if you are curious. Warm regards, Rick.
So after his experiences as a kid with a small telescope in NYC, he was offered a job at NASA !! Maybe he skipped a decade or two . . . ?? If not, I should be the head of NASA by now !!
It lost most of it’s magnetosphere shortly after formation which makes it a poor choice for a human colony imo. When it lost it’s magnetosphere it couldn’t hold it’s atmosphere because gravity alone isn’t enough to hold an atmosphere even on earth. Nobody seems to mention this when talking about terraforming Mars but maybe I’m missing something. I’m guessing it’s smaller size and further distance from the sun allowed it’s interior to cool faster, and it lost it’s plate tectonics as it cooled and therefore lost it’s magnetosphere. The magnetosphere protects us from solar wind and flares. I’m not an expert but it seems like it would be really hard to terraform Mars with it’s lack of magnetosphere and low gravity and we should probably pick a better planet or even a moon instead.
@@alexburke1899 i'd say impossible really, to terraform mars in anything resembling a practical manner. agree with you on all points, although i believe mars never had plate tectonics even as it cooled from molten state. mars' reduced size and reduced tidal forces from sun do indeed mean its interior cooled far faster than earth's. and i'd also say the list of reasons mars is unsuitable for colonization is a very long one
Sablicious NASA is limited by political restrictions which private enterprises aren't. The prove that NASA isn't being cost effective with their plans, just look up Robert Zubrin and Elon Musk's Space X. They will show you how much jerking around there's going on in NASA and other government funded space programs.
Sablicious The Chinese are always one step behind since all they do is copy Western innovation. I never said it was easy I just said that NASA makes it harder than it has to be which is why their deadline is so far away. The farther away you set a deadline the greater the risk of not fulfilling it.
I would love to go to mars and I believe I wouldn’t be the worst person to put there I’m 13 I love space, astronomy, I’m taking the life career of engineering and I’m a very creative and adaptable person And I’m in the top sets in all my classes at school
When you talk about desease, if or when people do go to Mars, and if there is life there, what about the danger of us taking our deseases to Mars, and possibly bringing something back that we can't control???
That's why they decontaminate probes as much as possible and regularly let them burn up in other planets atmospheres so as to not contaminate the planets/moons or bring anything back to ours
I have read in some papers that "this was a serious issue to be considered" when USSR tried to send the first Venera to Venus. We, humans, never landed anything on the surface of another planet before. And at that time, Venus was very promising to be habitable. USSR literally built its Venera 1 and 2 in a vacuum. Same applied to any landing missions (Not technically in vacuum, but in highly confined and sterilized places) So, any Mars rovers built to this days were made and test operated only in quarantine places, or at least, this is what they make us think.
@superdrengendk12 has a point concerning the lack of a magnetic field. It's what protects the earth's atmosphere from the radiations that would progressively strip it away.
We have the technology! We have developed the Dehumidifier, Oxygen Extractor, Hydroponics, Inflatable Buildings, and better rocket propulsion. Lets put these technologies together and go to #mars!
No Money is not the real issue. It's motivation. USA spends over 600 billion dolars on military alone, countries of EU spend even more on social security. Tremendously expensive things are being done. It's not, that we don't have the money, but we don't choose to spend them on trip to Mars. It's not Cold War anymore with its Space Race. So governments really don't care about space exploration, therefore they don't spend a lot of money there.
We need more engineers and scientists that are passionate about Mars! I for one and studying engineering and physics so I can help! We need to go to Mars! We need to inspire the young minds of tomorrow!
Even though more scientists and engineers would be useful, you will surely find out, that without political will, nothing this big will happen. By political will I mean either determination of large country officials (USA, Russia, China, EU) or determination of a rich company (SpaceX, GM, IBM). Because: if there is funding, scientists will come and work on the problem. You can't make Mars rocket in a garage, you need the means.
Going to Mars is a silly idea until we have a base upon the Moon. It is obvious that a base/fall-back position out of our gravity-well is the necessary first step. All these plans are basically moot until the Moonbase exists. IMO.
even it takes us a thousand years to give mars a makeover the endeavour is worth it. All nations of the world could work alongside each other giving humanity a common goal & vision. Mars could expedite peace.
Learn about the Dehumidifier, Oxygen Extractor, Hydroponics, Inflatable Buildings, and Terraforming. Lets put these technologies together and go to #mars!
jeff walls Two options: put a fusion reactor (which must naturally have an extremely intense magnetic field) or a large solar array running a magnetic field between the sun and Mars such that gravity holds it in that precarious spot and hope that it doesn’t get hit by an asteroid; (2) put a fusion reactor that generates its field sustaining power from the plasma’s own burning-induced magnetic fields opposing the containment field deep inside Mars.
Stand up centrifugal gravity rooms are a must on Mars. This should be used every day for 2 hours at minimum. There will be health benefits to bone and muscle structure.
sorry to tell you, but mars is way to lightweight to hold any considerable sufficient amounts of an atmosphere to protect from radiation, vaporization of water and all the stuff that brings that with it
lets explore space give it a go land on a planet name it hello we could build homes save for the future we could dig deep plant for awhile we could have fixtures rise in a moment we could sit tight excite and unwind lets explore space give it a go land on a planet name it hello
Good deeds, no question. But I'd like to know how they think to cope with the radiations issues. Everybody knows Mars atmosphere is too thin to protect against it.
Theory suggests that atmosphere is related to magnetic field... So why did the Mars magnetic field alter? The Watts theory suggests that the earth moved in space when it was hit by a giant meteor in the bay of Mexico... Could this same theory be true of Mars?
Why don’t they fix earth with the same tech they’re gonna build mars with? Why can’t they build an outer atmosphere to protect earth from asteroids or some sort of tech that interfere with it entering earths atmosphere. With technology and this kind open mind to create then figure out a way to save our beloved earth rather than abandoning it. Earth has given us so much! I love earth!
Gravity? Mars has 38% the gravity of earth. Its very likely, if not assured this low gravity will have permanent, and life-long negative health impacts. It could be a deal breaker. Venus on the other hand, has almost the same gravity as earth. Not to mention abundant solar energy, and earth like pressures and temps if you are floating at the right height in the atmosphere.
+Jeeto But on venus atmospheric pressure is 90 times higher than on earth. Plus its soil does not contain the necessary nutrients to grow crops, which the Martian soil does. Astronauts would have to grow their own food on the other planet.
Astronauts have spent more than 9 months in LEO and have returned without any serious health impact. With 38% of Earths gravity, I dont think it'll cause any serious problem. Plus the astronauts would have to wear suits when they roam around on Mars surface, so that'll put on some weight I guess
Venus is closer to the sun So I doubt there will be enough shielding from solar radiation to host Humans. And even if there was - the whole planet is likely to be engulfed by the sun when the sun becomes a red Giant. We need to move farther away from the sun because earth will also likely be engulfed hence - Mars.
S96 T23 There is nearly as much shielding as earth gets. And this means there is 8x MORE solar power than on Mars. And its got correct gravity, Planing for the sun to explode should not factor into anything. We need plan the next 1-50 years first, not worry about what is happening in 3 billion years.
Once tarra forming begins as described in this video the atmosphere of Mars will change. One important thing not mentioned in this TED segment is that this change will take hundreds of years. At that time there may not be humans in existence anywhere in our solar system.
Given that Mars doesn't have a significant liquid interior, how do we keep the cosmic rays that Earth's magnetic field deflects from stripping away any Martian atmosphere that we create?
People who live on Mars would have to use gravitational force or more commonly known as G force centrifugal rooms. This will cause weight per unit mass, to maintain Earth like bone and muscle mass and strong hart. L=2W.
it would take like four hundred years for it to do that there are quite an amount of ways of "providing" mars with a magnetic field, maybe you shouldn't be so lazy and actually search the internet a little bit the most "brute force" aproach is to build superconducting rings around the planet parallel to thr ecuator, but this is actually very expensive, there are other aproaches like placing an electromagnet of a couple os teslas in space in the Lagrange 1 zone, so the magnetic "tail" that would be created would be enough to greatly decrease the radiation from the sun of the WHOLE planet
We can warm Mars quickly, efficiently, and at low cost. Similar to a particle accelerator, we move asteroids into a low orbit from the asteroid belt and dial them into a collision with one another.
all the bad things that could or might happen to earth that can destroy the only living planet we have ever know , wouldn't happen to the humble planet of mars ???
Mars has a toxic soil, how do you detox it? Mars has no geological activity and no magnetic shield. How do you prevent the created atmosphere from getting blown away by solar radiation and solar flares? How do you protect against cosmic rays without a magnetic shield? Mars has lost its first atmosphere and ocean. How do you prevent this from happening again?
I hope they don't leave matt damon behind on this one.

There is a new Dark Ages that lasts 1,000 years.
In 3382 AD, a strange mutation will happen in the human brain. People will get a remarkable phenomenon referred to as hyper-vision or hyper-intuition. One after the other, man and women on Earth will acquire this new spiritual ability which will be an extremely powerful way of reaching ‘the great Spiritual Light’ and enable them to get ‘the Direct Knowledge.’
BETWEEN 3400 AND 4000 AD
This period can be referred to as the new ‘Golden Age’ since the previous century was a kind of ‘dark age.’ There will be ‘the Universal Creators’ (instead of the Global Parliament) who will combine the qualities and abilities of philosophers, artists, scientists, mystics, and all the other ‘quality people’ on Earth. Now, everything will be free - clothes, houses, food, transportation, EVERYTHING! There will be no private property, and the only things which will matter to people are honor and a good reputation. Hurrah, finally!
The technology and material standards of living will be unimportant, and people will care only about their emotional, mental and spiritual development. Self-improvement will be highly valued. One more thing is interesting here - in their whole life, people will work only two years! That will be between the age of 17 and 19. Can you even imagine this?
At this period in the Earth’s history, the population of people will be less than a billion. This is probably why there will be an abundance of products for a decent living for everyone. Also, there will be very few laws in the society since there are no criminal intentions of individuals in this society (What for when they are all smart and have everything they need to be happy?). Actually, there will be only three kinds of laws:
Those related to the 2-year working period.
Those that arrange how traveling traffic and distribution of goods is done.
Those that deal with the demographic stability of the population size, i.e. the general birth control.

Passion doesn't always mean common sense.
No matter what is done to try and terraform Mars, you would never be able to restore the magnetic field to shield the planet. Terraforming Mars is a huge pipe dream
Why not just focus and strive to save our beloved planet Earth?
It seems like, these days Ted has become a humour spot.
12:53 don't see the joke there, 13:43 don't see the joke there either
The whole presentation with its arguments is a joke
On 12:53, it was because "planetary engieering" isn't simpler than than "teraforming". On 13:43, it's the idea of a simple way to teraform a planet.
People always make fun of things until they work, Take the wright brothers for example.
@12:43 i think terraforming sounds like terror-forming and I have no idea why the 2nd one was funny. I don’t get it either.
Jo-Erland pointed it out but, the humore comes in when we talk of ANY plan to terraform Mars.
We can't terraform a planet using ANY plan if the planet in question has no magnetic dynamo which creates a magnetosphere which protects the planet. Ozone is only one of MANY things that protect life on this planet and without the magnetosphere, the solar wind actually strips away the atmoshpere, molecule by molecule.
Mars has no magmetosphere and so it cannot protect an atmosphere, even if we tried to build one. It's why it lost the majority of its atmosphere in the first place.
This guy has been kept out of the loop. We have been established there for decades.
2033 to 2039. Elon Musk will already have his first Mars Gigafactory setup and waiting by the time NASA gets there. 😹
True 😂👍
You forgot the law all life is exposed to
This Guy Is Awesome....
He skipped a step, you need to establish a magnetic field for Mars. Without that everything else is pointless. The good news is we have the tech to do that. It just requires a butt load of power.
+JoekerXXX luckily there is a lot of silicon on Mars, so we could build a lot of solar panel factories and let the panels do their magic.
+JoekerXXX No you don't.
@@TheJohan167 how about use thorium and nuclear energy.
Yes!
And the ability to get into space.....smh
That diss at SpaceX was uncalled for. But then again this was 2015 and starship was still under wraps and not announced
Nothing about what prolonged exposure to radiation and low gravity will do to the human body during a mission to Mars.
We were told, humans over populated the earth. I'm just a truck driver and every time I drive states like Wyoming, South Dakota, North Dakota, Utah, Montana, Idaho, Oregon, Texas, Arizona, Nevada, Kansas, Colorado even Northern California Eastern California, you don't see buildings or town going through those places. I'm a truck driver and I know where can get stuck in traffic most. Cities and people are usually over populated by the oceans. My point is why do we plant trees in those empty open lands and spread out people.
Why are so many of these people talking about "once we've got a atmosphere, we put plants on the surface to turn CO2 into O2" as if thats a suitable solution? Wont the process of creating suitable levels of O2 (and more importantly, lower levels of CO2 as its usually not a lack of oxygen that suffocates you but too much CO2) take millions of years with plants? They're not superfactories or we'd solve the 0.005 % extra CO2 in earths atmosphere from global warming by simply planting one new forest on an empty patch of land.
No. For this you need superfactories. One that we can't make yet or we'd place one here to solve global warming.
Machines can exract O2 from CO2
THE THICKER THE ATMOSPHERE , MORE SUITABLE FOR US TO LIVE. THEIR IS 98 PERCENT OF CO2 WHICH CONSISTS OF 78 PERCENT OF O2. WHAT WE NEED IS O2 AND THE REST IS EASY. I GUESS.
its more about having an atmosphere so construction and living is easier, you will be able to walk around with an oxygen tank.
if we detonated some super powerful nukes over the poles it would do it
Jesse Jensen I was talking about turning CO2 into oxygen, which he said we'd do just by placing some plants.
Creating an atmosphere is another matter
wouldnt take millions of years with plants, maybe a thousand but more likely a couple hundred.

The interior of Iceland is purported to be uninhabitable. But what about Mars? Obviously, Mars is even more uninhabitable because you can't even breath the air or survive outside without a pressurized suit!
He forgot to address the magnetosphere problem. This guy pitched a plan that will make Mars even harder to terraform.
If Mars is such a great place for life, why isn't it there already?
Insanity can be expressed so rationally as to sound normal But it is insane to even think about "terraforming" mars. We need to fix the problems here created by materialism and rampant consumerism.
This guy is the man, smart and funny
only 1 BIG PROBLEM - MARS has weak/non-existing magnetic core compared to Earth. It get's bombarded with solar wind, the reason it lost the atmosphere. Unless we can restart the magnetic core of the planet, you will not enjoy the outdoors ;-)
+tom maly Lets nuke the shit out of the planet until the core is reignited
nukes won't do shit to a planet core
+tom maly loop wires round mars and run electricity through them. Use superconducters
+tom maly Yes, that is true, and we won't be able cover the entire planet, at least with 21-century technology, which of course means that atmosphere will be lost slowly. However, that doesn't mean that you can't live outdoors, because you could build solar powered electomagnets that gives a magnetic field to every Martian city. In the thousands and thousands of years it will take for the atmosphere to dissappear after we create it, we can probably figure out how to shield the entire planet to give it a sustained magnetic field.
playing god
I'll volunteer for space travel. I may die, but getting to see and touch another planet is something I couldn't pass up. I hope we get there soon
I'm happy that we are finally getting our buttocks out into space. I am sad that it happened so slowly, that I am unlikely to ever experience it myself, or even see a real colony established. Oh, time, how cruel you are.
Dang I'm gotta be more grateful, Im only 15 im gonna see a lot
Earth to Pupax - TV's show ain't proof of nuthin but yo' gullibility. Now give us the sad face, clown.
Do you have a degree in science or would you be cleaning bathrooms on Mars?
When I was in high school, I has every expectation that, by now, the colonization of Luna would be well underway and that we'd have had expeditions to Mars. It should have happened, too.
@@stevenpilling5318 It's because the cold war was a time of competition between nations which led to rapid technological development. To bring that pace of development back, we need countries to challenge each other technologically. The rise of China might be of help to us, but if India and Russia could also chip in then we'd be on Mars in no time...
Interesting that he said it was a Tuesday. In India, Tuesday is called Mangal-vaar and in vedic astrology it is the day dedicated to/ruled over by the planet Mangal which is Mars.
I've often wondered (feel free to give me some input - I am curious), if it is not feasible to take some of our many nuclear weapons and "bomb" the north and south poles of Mars. There are no people there now. That would be a more productive use of nucear weapons, melt the dry ice, cause global warming. If people go there in 20 years, the atmosphere could be much more accomdating. There is little or no radiation in Hiroshima, Japan today. Radiation does dissipate. Could we use nuclear weapons in limited quantities to melt dry ice but not create an excessive amount of radiation on Mars?
Hi Trevor,
The energy in an atom bomb is TINY compared to the energy from the Sun. The heat from an atom bomb radiates back into space, and soon is gone.
However, if we can make Mars' atmosphere thicker, it will KEEP the heat from the sun longer. If we can make Mars darker, it will STAY warmer. If we add super green house gases then they will absorb 7,000 times more heat than CO2, and last for decades or centuries.
I'm not saying that bombs are useless. "Clean Pipe Hydrogen Bombs" (which use deuterium and conventional explosives to set them off, rather than a fission bomb), could blow up nitrate beds on Mars and put back N2 into the air. That might be a good use for bombs. Or cracking rock to let a liquid aquifer come to the surface.
There are several good books on Terraforming, the best is: "Terraforming: Engineering Planetary Environments", by Martin J. Fogg, to read if you are curious.
Warm regards, Rick.
So after his experiences as a kid with a small telescope in NYC, he was offered a job at NASA !! Maybe he skipped a decade or two . . . ??
If not, I should be the head of NASA by now !!
10:15 it's like asking why become a 7 continent specie?
current prevailing theory is mars was never warm enough to have liquid surface water, just a good amount of surface ice
It lost most of it’s magnetosphere shortly after formation which makes it a poor choice for a human colony imo.
When it lost it’s magnetosphere it couldn’t hold it’s atmosphere because gravity alone isn’t enough to hold an atmosphere even on earth. Nobody seems to mention this when talking about terraforming Mars but maybe I’m missing something.
I’m guessing it’s smaller size and further distance from the sun allowed it’s interior to cool faster, and it lost it’s plate tectonics as it cooled and therefore lost it’s magnetosphere. The magnetosphere protects us from solar wind and flares.
I’m not an expert but it seems like it would be really hard to terraform Mars with it’s lack of magnetosphere and low gravity and we should probably pick a better planet or even a moon instead.
@@alexburke1899 i'd say impossible really, to terraform mars in anything resembling a practical manner. agree with you on all points, although i believe mars never had plate tectonics even as it cooled from molten state. mars' reduced size and reduced tidal forces from sun do indeed mean its interior cooled far faster than earth's. and i'd also say the list of reasons mars is unsuitable for colonization is a very long one
2033-39? Are you kidding me? This should be done at the end of this decade or the very least next one.
Sablicious NASA is limited by political restrictions which private enterprises aren't. The prove that NASA isn't being cost effective with their plans, just look up Robert Zubrin and Elon Musk's Space X. They will show you how much jerking around there's going on in NASA and other government funded space programs.
Sablicious Your "government funded" argument is a fallacious appeal to authority.
Sablicious The Chinese are always one step behind since all they do is copy Western innovation. I never said it was easy I just said that NASA makes it harder than it has to be which is why their deadline is so far away. The farther away you set a deadline the greater the risk of not fulfilling it.

I would love to go to mars and I believe I wouldn’t be the worst person to put there
I’m 13 I love space, astronomy, I’m taking the life career of engineering and I’m a very creative and adaptable person
And I’m in the top sets in all my classes at school
The Russian meteorite of 2013 did NOT destroy many hundreds of buildings. It broke a lot of windows resulting in cuts to people.
When you talk about desease, if or when people do go to Mars, and if there is life there, what about the danger of us taking our deseases to Mars, and possibly bringing something back that we can't control???
That's why they decontaminate probes as much as possible and regularly let them burn up in other planets atmospheres so as to not contaminate the planets/moons or bring anything back to ours
I have read in some papers that "this was a serious issue to be considered" when USSR tried to send the first Venera to Venus.
We, humans, never landed anything on the surface of another planet before. And at that time, Venus was very promising to be habitable.
USSR literally built its Venera 1 and 2 in a vacuum. Same applied to any landing missions (Not technically in vacuum, but in highly confined and sterilized places)
So, any Mars rovers built to this days were made and test operated only in quarantine places, or at least, this is what they make us think.
how are you going to terraform the planet without a strong magnetic field and atmosphere?
terraforming is making the atmosphere
but how can you trap carbon in the first place, if there is almost no atmosphere, doesn't i just slip right into space?
@superdrengendk12 has a point concerning the lack of a magnetic field. It's what protects the earth's atmosphere from the radiations that would progressively strip it away.
No idea.
lol yeah, only a few hundred million years
I hope this will happen. So excited to live in a new planet.
"It was a Tuesday...."
everyone has the same interests in Mars is beautiful minded people who has an instrested in the the future of mankind you rock!!
We have the technology! We have developed the Dehumidifier, Oxygen Extractor, Hydroponics, Inflatable Buildings, and better rocket propulsion. Lets put these technologies together and go to #mars!
they miss one thing unfortunately.... money :(
No
Money is not the real issue. It's motivation. USA spends over 600 billion dolars on military alone, countries of EU spend even more on social security. Tremendously expensive things are being done.
It's not, that we don't have the money, but we don't choose to spend them on trip to Mars. It's not Cold War anymore with its Space Race. So governments really don't care about space exploration, therefore they don't spend a lot of money there.
We need more engineers and scientists that are passionate about Mars! I for one and studying engineering and physics so I can help! We need to go to Mars! We need to inspire the young minds of tomorrow!
Even though more scientists and engineers would be useful, you will surely find out, that without political will, nothing this big will happen. By political will I mean either determination of large country officials (USA, Russia, China, EU) or determination of a rich company (SpaceX, GM, IBM). Because: if there is funding, scientists will come and work on the problem. You can't make Mars rocket in a garage, you need the means.
This is a cool Kickstarter if you like Science Documentaries.

Going to Mars is a silly idea until we have a base upon the Moon. It is obvious that a base/fall-back position out of our gravity-well is the necessary first step.
All these plans are basically moot until the Moonbase exists. IMO.
At the current rate, no one is going anywhere. Our planet is dying before we have actual means to go somewhere else safely.
I met him and he is awesome....
even it takes us a thousand years to give mars a makeover the endeavour is worth it. All nations of the world could work alongside each other giving humanity a common goal & vision. Mars could expedite peace.
I love it that he just used the first image for "ice core".

So glad NASA is going to bring astronauts back! They’ll have a great going away party from the colonists!
What about the gravity of Mars?? It's able to hold the atmosphere around the Mars once the atmosphere formed??
No
I'm going to ask the most basic question: Who is "we"?
Not you and I ! Thats for sure !!!!
Hahahahaha
Nothing ventures, nothing gains. We should bring many different species of cacti to Mars for experimentation.
Is the audience drunk or just over excited. Too much StarWars.
I knew deep down that the Death Star wasn't made to destroy but give life @13:48. The Jedi were wrong afterall.
OK...but what about the magnetic field...?
jeff walls Two options: put a fusion reactor (which must naturally have an extremely intense magnetic field) or a large solar array running a magnetic field between the sun and Mars such that gravity holds it in that precarious spot and hope that it doesn’t get hit by an asteroid; (2) put a fusion reactor that generates its field sustaining power from the plasma’s own burning-induced magnetic fields opposing the containment field deep inside Mars.
They plan to find natural shelters underground as they are planning to do on the moon.
Love this guy
11:20 Near miss?
IT'S A NEAR HIT!!!
A COLLISION IS A NEAR MISS!!!!
~George Carlin
The asteroid missed. It was a miss, a close miss. In other words a near miss.
Stand up centrifugal gravity rooms are a must on Mars. This should be used every day for 2 hours at minimum. There will be health benefits to bone and muscle structure.
In 2033 or so Elons droids will be there to welcome you with soda and earth bars.
sorry to tell you, but mars is way to lightweight to hold any considerable sufficient amounts of an atmosphere
to protect from radiation, vaporization of water and all the stuff that brings that with it
It would be cheaper to just transform Earth into a planet like Mars. We are making such good progress in that area, and it has no political downside.
AI is definitely closer than many people think. Especially as we’re all talking to computers nonstop.

Enjoy that lethal dose of radiation robert reid. And take all these myth believing clowns with ya.
Good deeds, no question. But I'd like to know how they think to cope with the radiations issues. Everybody knows Mars atmosphere is too thin to protect against it.
Theory suggests that atmosphere is related to magnetic field... So why did the Mars magnetic field alter?
The Watts theory suggests that the earth moved in space when it was hit by a giant meteor in the bay of Mexico... Could this same theory be true of Mars?
Why don’t they fix earth with the same tech they’re gonna build mars with? Why can’t they build an outer atmosphere to protect earth from asteroids or some sort of tech that interfere with it entering earths atmosphere. With technology and this kind open mind to create then figure out a way to save our beloved earth rather than abandoning it. Earth has given us so much! I love earth!
#occupyvenus
Mars is our future
They should travel to Fukushima or Chernobyl and make that habitable
I bet this guy is fun to be around.
Gravity? Mars has 38% the gravity of earth. Its very likely, if not assured this low gravity will have permanent, and life-long negative health impacts. It could be a deal breaker. Venus on the other hand, has almost the same gravity as earth. Not to mention abundant solar energy, and earth like pressures and temps if you are floating at the right height in the atmosphere.
And the Venusian atmosphere will give you shielding from solar radiation... Mars doesn't have any of that protection
+Jeeto But on venus atmospheric pressure is 90 times higher than on earth. Plus its soil does not contain the necessary nutrients to grow crops, which the Martian soil does. Astronauts would have to grow their own food on the other planet.
Astronauts have spent more than 9 months in LEO and have returned without any serious health impact. With 38% of Earths gravity, I dont think it'll cause any serious problem. Plus the astronauts would have to wear suits when they roam around on Mars surface, so that'll put on some weight I guess
Venus is closer to the sun So I doubt there will be enough shielding from solar radiation to host Humans. And even if there was - the whole planet is likely to be engulfed by the sun when the sun becomes a red Giant. We need to move farther away from the sun because earth will also likely be engulfed hence - Mars.
S96 T23 There is nearly as much shielding as earth gets. And this means there is 8x MORE solar power than on Mars. And its got correct gravity, Planing for the sun to explode should not factor into anything. We need plan the next 1-50 years first, not worry about what is happening in 3 billion years.
Awesome
and then came ELON !
Show us the way Frodo!
And mine!!
Thanks I really liked this video 🚀🚀💫
Those who thinks that Mars mission is as simple as seen in movie, let me tell u that scientists still have no solution of high wind on Mars to stay!!
The atmosphere is so thin that even an 80mph gust would feel like a faint breeze
What is more crazy? Colonizing the Asteroid Belt or Colonizing the System?
That random dude who laughs at 4:54
He laughed late 😂
Population of Mars is a necessity, for the continued life of the human species !!!
Will the Chinese colonists allow us to land?
Once tarra forming begins as described in this video the atmosphere of Mars will change. One important thing not mentioned in this TED segment is that this change will take hundreds of years. At that time there may not be humans in existence anywhere in our solar system.
Why seek to green Mars and colonize it when we have so much land that is a desert waste land here on earth?
It just doesn't make any sense.
Given that Mars doesn't have a significant liquid interior, how do we keep the cosmic rays that Earth's magnetic field deflects from stripping away any Martian atmosphere that we create?
The only way NASA gets to Mars is with SpaceX...
People who live on Mars would have to use gravitational force or more commonly known as G force centrifugal rooms. This will cause weight per unit mass, to maintain Earth like bone and muscle mass and strong hart. L=2W.
Mars doesn’t have magnetic field. How are you going to keep atmosphere around mars? The solar radiations will blow that atmosphere down in space.
it would take like four hundred years for it to do that
there are quite an amount of ways of "providing" mars with a magnetic field, maybe you shouldn't be so lazy and actually search the internet a little bit
the most "brute force" aproach is to build superconducting rings around the planet parallel to thr ecuator, but this is actually very expensive, there are other aproaches like placing an electromagnet of a couple os teslas in space in the Lagrange 1 zone, so the magnetic "tail" that would be created would be enough to greatly decrease the radiation from the sun of the WHOLE planet
We can warm Mars quickly, efficiently, and at low cost. Similar to a particle accelerator, we move asteroids
into a low orbit from the asteroid belt and dial them into a collision with one
another.
all the bad things that could or might happen to earth that can destroy the only living planet we have ever know , wouldn't happen to the humble planet of mars ???
of course it will, but double the chance. It's very simple, you need at least two nuclear wars to wipe out mankind now!! Wonderful!!
Enjoyed listening to you. Thanks for sharing.
Well, this didn't age well...
How's so?
Mars has a toxic soil, how do you detox it? Mars has no geological activity and no magnetic shield. How do you prevent the created atmosphere from getting blown away by solar radiation and solar flares? How do you protect against cosmic rays without a magnetic shield? Mars has lost its first atmosphere and ocean. How do you prevent this from happening again?
