Carbon dioxide is not poisonous, after all plants thrive with it. For most animals, it is a asphyxiant. The magnetosphere has been blamed for Mars' loss of atmosphere, BUT Venus also has no magnetosphere, and is MUCH closer to the sun. The critical factor, is the gravity of the body - a more massive body holds on to it atmosphere much better than a low mass body.

Venus' extra dense atmosphere resists the solar wind in what's called the blanketing effect. Also, if Venus rotated as fast as Mars, it would have have a magnetosphere compatible to our own. Mars has plenty of gravity to hold an atmosphere. It was its low density and volume that caused a decrease in geothermal effects and the cessation of geomagnetism. That latter, in particular, was the kiss of death. If a way can be found to shield the atmosphere, Mars could regain its former status as a viable planet. This needs to be done, too, as soon as practicable.

We would need to add a lot of nitrogen. The plants will need it, and we need an inert gas that is roughly the same molecular weight as O2. We'll probably end up mining it from the Kuiper Belt. While we're doing that, we can bring down a lot more water and other useful ingredients. I worry about the weather, though. Planet-wise dust storms are not that big of a deal when there is almost no atmosphere, but they would be much more serious with a thick atmosphere -- especially if the wind speeds remain as high as they now get. The Martian soil also appears to be very chemically reactive. That could also be a problem.

Mars... Sucks! I love the perfect timing with the bird at 0:46

So many unanswered questions, the most pressing for me being: 1. The oceans of water that existed on ancient Mars also escaped to the outer space along with most of the Martian atmosphere when the solar radiation came or is it all just stored in the poles? (If the atmosphere and water of Mars can't be replenished from outer space sources and we have to wait for the planet itself to replenish them then it's not worth it in my humble irrelevant opinion) 2. How the hell could you build that L1 shield thing, is it feasible? How does it work? I want to know more.

I love your videos! especially as a planetary scientist. An oxygen rich atmosphere would just push Mars microbes further underground, exactly what happened to anaerobic bacteria on early Earth after photosynthesis began. Spread life throughout the cosmos! By the way, when you deliver your lines are you reading from a script or do you memorize a line and then deliver it to te camera? That’s what I try to do in my videos (on another channel).

Hey Fraser! Thank you for the great content. Seeing your video on the Martian atmosphere made me wonder if a magnetic field - like the one on earth - can be recreated artificially. It seems to me like the magnetic field produced here on earth by the core, works much like magnets. Could we then not just simply put very large electric magnets at the poles of Mars in order to shield it from solar winds and keep the atmosphere from being eroded away? Instead of putting a shield at an L point, it could then be constructed on ground

Getting humans on Mars is a great idea BUT our sun only has a few billion years left. That might seem like a long time but it's really not in comparison to the universe. Once the Sun dies any life in our solar system will die with it. We should be persuing Mars but at the same time we should be looking into other solar systems as well. SpaceX is doing the right thing with reusable rockets, interplanet travel will be a common thing in the future. Wish I could live long enough to see it.

Hi Fraser, I have been watching your videos for a long time. I have a question on my mind . Given the fact that Enceladus has a low gravity if we can reach the depth where the temperature is habitable , would we be able widstand the pressure from the water and harvest the thermal energy of the planet to eventually reach a equilibrium where life is possible?

Cool stuff, really begs the question of future terraforming operations. Will laws be enacted to protect alien life, and what kind of people will there be who might break those laws...

Maybe use mars for fossil fuel factorys, mars will get warm and the entire plant can be industry

I believe there is still microbial life present on mars, due to the methane releases in the spring months, and that such life should adapt lowly to the steady changes in atmosphere pressure and concentrations due to the fact we are restoring what was there before. The decease in radiation from a magnetic shield over the planet would increase the habitable area for life on the surface. The perchlorates in the soil will be another problem for all life forms. Also the changes will take place over centuries which should allow us enough time to discover the life present, we might even be able to create hybrids of earth dna animals and plants mixed with mars dna to see how the ecosystem might have looked like.

@frasercain

5 жыл бұрын

The methane mystery is really intriguing, and I hope we can get an answer to it soon. If we do work on restoring the atmosphere, we should see a response from whatever biosphere remains on Mars as conditions improve.

I want to know more about whatever that radiation shield is and how it's to be built... Also, the effort into spinning habitats (without the outer, shielding mass spinning) would probably be far cheaper, per person, housing.

with the life that we think mars has, it would be very much ready to have it terraformed as that would restore it to the time it evolved

Fraser, Most definitely we should undertake such an experiment! Clearly with first recording and understanding in great depth the Martian planet but once this is accomplished, we must proceed in Terraforming it. Humanity will learn a tremendous amount from such an experiment and it will create a first sister planet which will permit us to consider other opportunities further afield!

While I'd have mixed feelings going to another solar system and colonizing it against the wishes of any native life (even rudimentary life that might evolve over millions of years), I think there's a small but real danger that some asteroid or planetary collision could wipe us out at some point if we don't do it ourselves. We should definitely colonize a second world, and Mars is one of the closest and most likely candidates. As one of the native species in this solar system, and possibly the only one with the capabilities to do it, I feel that it is probably within our rights to do so. A bigger question is, "who owns it"? Terraforming is no small task, and traditionally in most societies on Earth, those who put effort in reap part of or most of the reward. That said, this is a planet. It's HUGE. This will require monumental effort across generations, and much consideration before the first company or country to get there starts shouting "Dibs, dibs!

How much energy will it take to maintain and develop the artifical magnetosphere? And as the core I've overheard is almost chilled, how much power would it take to revive the core to induce natural geological activity again? And how do you know it's lower gravity will be acceptable for humans in the long run? This theory is good but with it comes drawbacks

A couple of questions. How much of a magnetic field force does earth has? How much magnetic field force mars need to keep its atmosphere in? What does it mean in GW? Or simply is possible to create magnetic field strong enough on Mars by building a nuclear power plant on the poles? And so on and so forth...

I think mars needs heat to help sublimate frozen gasses back into atmosphere, then, solar wind needs a long time to blow that atmo again. Maybe a thin layer of rapid metabolism bacteria and other light absorbing dust would help raising tempereture. Once gasses are up they provide shielding and sustain higher tempereture. Venus is closer to sun, no magnetic field, but with very thick atmosphere.

Well, in terms of actual strength, the Earth's field is maybe 1% as strong as your average fridge magnet. The thing is, it's BIG. It is extremely hard to get large magnetic fields, the field tends to be loosely proportionate in size to the source of the field, if field strengths are equal. The trick with the method in this video is, since solar wind is radially moving out from the sun, you don't need a full field, just one big enough to 'shadow' the planet. It'd have to be a little stronger to do that, but really that's still a pretty tiny field strength. Make it out of huge loops of thin wire coming from a central power generator, or if you're feeling clever take a big ol' nickel-iron asteroid and magnetize the whole thing and stick it there. Mars only really needs that field to deflect the charged particles from the Sun, so any field strong enough to curve those out of a path that would hit Mars is enough. Since there's a long distance to travel, that equates to only a tiny angular deflection, so really a slightly weaker field than Earth's would probably still suffice. All that extra distance between Mars and the Sun-Mars L1 point really helps. As for your last question, magnetic fields are created by moving charge in a circle. So, just sticking some big power generators at the poles wouldn't be enough. You'd have to be moving charges in a huge circle around the planet's equator to directly shield the whole planet from the surface, or just have hundreds or thousands of smaller loops blanketing the surface. Even with the idea here, it wouldn't solve all the issues. There's still substantial quantities of radiation from other directions, due to plasma dynamics from the surrounding solar wind and cosmic rays. Also, this thing would have to have a field strength maybe 50 microtesla (about earth's field strength) at 1 earth radius in order to totally shield Mars from all solar wind issues. Which basically means somehow making a magnetic generator station that can almost duplicate Earth's magnetic field and putting it in the proper place. And if we can do that, we'll probably want one in the Earth-Sun L1 point too, as insurance against solar flares wrecking our stuff. That's because when the field is originating from the planet, it helps avoid atmosphere loss directly, by recapturing lost gas particles, rather than indirectly by trying to avoid this ionization altogether. Long story short: could be a really good plan, if we can figure out how to do it.

SqrsYT The field strength is not that large for a magnetic field placed at the Lagrange point. I would have to google the number for you. To generate an artificial magnetic field on Mars would require passing an electric current through the Martian surface. That would be some serious power generation. Not to mention all of the assorted technical issues with power generation and transmission on another planet with no infrastructure. The idea of the magnetic shield is still new. Until only about two years ago no one had thought of it. I’m hoping that it can be developed into a workable solution.

@Menachem David Yes, but focusing on heating mars not only should thicken its atmosphere and shield it from particles, but also creates an induced magnetic field, so yo heat mars, you get a megnetosphere as a bonus! www.astrobio.net/also-in-news/a-magnetic-surprise-from-venus/

Question: How large would the shield placed at the Lagrange 1 point proposed by Dr. Jim Greene need to be to stop or impede the solar wind from hitting Mars' atmosphere? Thanks

Going through such a MASSIVE undertaking as building a shield that completely blocks the solar winds of an ENTIRE planet which would warm Mars average temperatures by a few degrees over the course of several generations..... But driving SUVs here on earth will do the same even quicker, Riiiiiiiight.

lol there is no way that the earth will be populated by our 'current humans' 1000 years from now! We'd have a better chance of successfully modifying Mars to the amount that we need, than our ability to stay alive long enough for that to occur.

Hi Fraser. Do you know when we may be expected to see images of the Milkyway’s supermassive black hole? And what do you expect to see?

interesting... especially when so many sources state that even with a magnetosphere the gravity on Mars would not be able to prevent a critical loss of atmosphere over time. So terraforming would have to be a constant extreme-cost effort if it is possible at all. Maybe we can START doing that in millennia.

Terraforming Mars is a huge waste of time. By far a more efficient way of creating living space for Earthlings (humans, animals & plants) is spinning habitats floating in zero-G vacuum. Pound for pound spinning habitats will provide a million times more living space. Mars is a gravity well that is difficult to safely get into and get back out of. Shallower than Earth's but a significant enough gravity well. Getting to and from a spinning habitat is best done with low-thrust rockets. Habitats will have the shallowest gravity well possible. Any planetary body will have day/night cycles which makes solar energy a pain to utilize, requiring massive battery storage. A habitat in free space will be bathed in solar radiation 24/7/365 in zero-G meaning you can build a solar farm as big as your imagination to collect more energy than you could possibly know what to do with, all with minimal battery storage. Habitats could be brought into being incrementally. Start small and work up to more and bigger as needed. Terraforming Mars is all-or-nothing, tin-can living for the first few hundred years. I say, save Mars for building materials for spinning habitat construction and don't waste time turning it into Earth 2.0

Hey Fraser, A question popped in my mind. As the sun is getting hotter day by day, the earth’s temperature is rising too and the goldilock zone is shifting. Right? Will shifting earth by few million miles solve the problem? Will it effect seasons on earth? What will the impacts on earth for this process if we would be able to shift? Please include my question in your QnA programme.

So considering the magnetoshield is build able using existing tech - are we going to build it? And when?

Fraser Cain Where did you get the picture of Mars with oceans?

Hi Fraser, say we get Mars atmosphere to the level of what we have on Earth. Would there be a temperature difference between Earth and Mars due to different distances from the Sun?

If you placed a disc capable of stopping Solar winds at the L1 LaGrange point between Mars and the Sun, what would the diameter of that disk need to be to block the solar winds entirely from reaching Mars?
