Weird how around 22:00 he talks about how Venus has no water, but never mentions the fact that Mars has no nitrogen. Even if Mars had enough oxygen to support humans (which it doesn't in its ENTIRE mass) it would still need 4x as much nitrogen added to be habitable. Which also could not happen, because if Mars was capable of holding onto an atmosphere it would already have one. Meanwhile, Venus only needs to be cooled enough for the CO2 to precipitate out for it to have an atmospheric density similar to Earth's. We can get oxygen from mechanically dissociating it from the CO2, and it already has nitrogen, too. And that's exactly what we'll need to do to Earth in the future if we want to keep living here. Both planets lack magnetospheres, but if we have to economize it would make more sense to cool down Venus than heat up Mars, and spend more on solving the solar wind problem on the former instead.

Doesn't really matter. The sun's radiation will sterilize any plant before that happens anyway. Mars is geologically inactive and has no Magnetosphere to protect the surface from solar winds and radiation. This radiation will even strip mars from any athmosphere we may build up. Long term survival is not possible in these conditions. When i remember correctly you need about 3 meters of water or 5 meters of rock over your head to reach survivable levels of radiation. Living in caves is not very desirable. Many mars colonist will probably suffer from cancer and psychological problems. Just imagine living on a dead and deadly rock, years away from the only place in the universe that is perfect for you. Imagine never being able to feel wind or the sun on your skin, never smell the sea or a forest. Never hearing the birds sing. Just sitting in an underground bunker all the time with maybe a few short trips to the surface now and then. Absolutely horrible. Dust on airogel is the last thing to worry about.

Development of a Mars Habitat: Three-Step Evolution Towards Biomimetic and Self-Growing Structures The vision of a sustainable Mars habitat requires innovative solutions that are adaptable, lightweight, and efficient, especially in the extreme conditions of the Martian environment. To meet these demands, a progressive approach is envisioned, moving from traditional engineering techniques to advanced biomimetic and ultimately self-growing materials. This paper outlines the three development steps: Step 1: Traditional Engineering ("Old School") Approach Step 2: Biomimetic Silica Aerogel Structures Step 3: Silicon-Based Self-Growing Structures Step 1: Traditional Engineering ("Old School") Approach Concept Overview The initial design of the Mars habitat, as described in the Mars Gummi-Glashaus project, involves a hybrid structure combining high-performance materials like borosilicate glass, Inconel or titanium frames, and silicone rubber. This step focuses on the use of materials and technologies that are currently well-understood and readily manufacturable, albeit adapted for Martian conditions. Key Materials and Structure: Silicone rubber for the foundation and walls, providing flexibility and airtight seals. Borosilicate glass with insulation for windows, offering durability, transparency, and resistance to UV and radiation. Titanium or Inconel frame for the structural skeleton, known for corrosion resistance, strength, and temperature stability. Solar panels for energy, covering the roof and producing enough electricity for habitat operations. Agricultural areas integrated inside the habitat to support food production and oxygen generation. Advantages: Proven technologies: Materials such as borosilicate glass and titanium are extensively used in aerospace and engineering projects. Quick deployment: This approach can be implemented relatively quickly using current manufacturing methods. Robustness: The structure is designed to withstand Mars’ harsh conditions, including dust storms, extreme temperatures, and UV radiation. Challenges: Transport costs: Due to the weight and bulk of materials, the cost of transporting these to Mars will be substantial. Thermal insulation: While borosilicate glass provides some insulation, maintaining internal temperatures on Mars requires additional energy expenditure. Step 2: Biomimetic Silica Aerogel Structures Concept Overview Building upon the foundation laid in Step 1, the second phase introduces biomimetic design principles into the Mars habitat. In this phase, silica (SiO₂) aerogel serves as the primary material for thermal insulation, combined with a network of silicon-based reinforcing webs. This structure takes inspiration from natural systems such as leaf veins or blood vessels, distributing mechanical stresses while maintaining lightweight and efficient properties. Key Materials and Structure: SiO₂ aerogel: An extremely light, porous material known for its excellent thermal insulation properties. It serves as the main envelope for the habitat, providing insulation from the extreme cold of Mars. Silicon-based "webs": Reinforced silicon strands (similar to biological veins or tree leaf structures) act as a skeleton within the aerogel, offering structural stability without significantly adding weight. These webs would support the aerogel, distributing mechanical loads and preventing collapse under external pressures. The silicon "branches" would be designed to mimic biological structures that efficiently manage stress and material use, such as the vein structures in leaves or skin membranes. Advantages: Ultra-lightweight: SiO₂ aerogels are one of the lightest materials available, significantly reducing the weight of the structure. Thermal efficiency: Aerogels provide extremely high thermal insulation, greatly reducing energy requirements for maintaining internal temperatures. Biomimetic strength: The silicon webs improve mechanical resilience, distributing loads more effectively and preventing collapse in high-stress areas. Challenges: Complex manufacturing: Integrating silicon webs into aerogel may require advanced manufacturing techniques, possibly involving 3D printing or nanotechnology. Material durability: Although aerogels have great insulating properties, their brittleness could pose a challenge. The silicon reinforcement would need to be carefully designed to prevent material failure. Step 3: Self-Growing Silicon-Based Structures Concept Overview The final stage of development introduces self-growing structures inspired by biological systems but utilizing silicon-based materials. This approach represents a fundamental shift in how structures are conceived, moving from static to dynamic, adaptable systems. These silicon-based materials could have the capability to self-repair, grow, and adapt to the Martian environment, much like how plants grow and repair themselves on Earth. Key Materials and Structure: Silicon-based "biological" polymers: These materials would be engineered to mimic biological growth processes, allowing the habitat to expand or repair itself using locally available Martian materials (e.g., silica). These structures could involve silicon-nitride or silicon-carbon chains, with the ability to self-assemble into complex, load-bearing shapes. The material would respond to environmental stimuli (e.g., temperature, pressure) by growing or strengthening in key areas, much like a tree adds more wood in response to stress. Autonomous growth: The system would be designed to "grow" additional material where needed, such as in areas of high stress or damage. This could be achieved by integrating chemical processes that convert Mars’ atmospheric and soil components into usable silicon or silica materials. Self-repair mechanisms: Inspired by biological healing, the material could detect damage (e.g., from micrometeoroid impacts) and trigger a self-repair process, filling in cracks or reinforcing weak points. Advantages: Adaptability: The habitat would be able to grow and adapt to changing conditions or expand to accommodate larger populations over time. Self-repair: Maintenance would be minimized as the structure would have the ability to heal itself. Sustainability: By utilizing materials from the Martian environment, the habitat could become less reliant on supply chains from Earth. Challenges: Advanced bioengineering: Developing materials with these capabilities requires cutting-edge research in synthetic biology, biomaterials, and nanotechnology. Unpredictability: The behavior of self-growing systems might be harder to control or predict, requiring robust monitoring and fail-safes. Development timeline: This technology is still in the conceptual stage and may take several decades to fully develop. Conclusion The development of a Mars habitat presents unique challenges that can be addressed through a phased approach. The first step involves the use of traditional, well-understood materials that are already available, offering robustness and reliability. As technology advances, the incorporation of biomimetic principles-using silica aerogels with silicon reinforcements-will lead to lighter, more efficient structures inspired by nature. The ultimate goal is to achieve a fully self-sustaining habitat, where self-growing silicon-based materials allow for autonomous expansion and self-repair. This progression not only mirrors the evolution of life on Earth but also represents the future of space colonization, where structures can grow and evolve to meet the needs of their inhabitants.

Low atmosphere means we'd want to DRILL deep deep holes on mars 1st. Low atmos = low pressures = less friction, better cooling. Earth = hard to drill into the mantle: Mars = very doable if the equipment was on the planet. Drill a few hundred miles deep into the planet (strategically, where there are giant caves or extinct lava tube systems) = idea living place for early colonies. - deep underground = protected from radiation - exposed initial underground mineral deposits = good early access points for mines. - There is prob some geothermal heat on Mars = we wouldn't need to heat the colony, the ground would do that = saved energy - The surface (even if domed) is gona be very inhospitable as its even semi-terraformed) = living underground is preferrable. - Mars transition elements/actinide/lanthanides are prob in its mantle/core. It'd be cheaper to bring initial drilling equipment to get that deep, then mine those elements THERE; rather than bring it all TO MARS. = The beginning of (how/why you end up with a Matrioska Shell World, of sorts).

[@tkc1129]

Oh lordy! I loved talking about this kind of stuff, and it's understandable to want to see your theories in action, but astronomers seem WAYYYYY overeager to get started on terraforming. "Let's send a few more probes and then get started" seemed to be what they were getting at. I think we need a LOT more scrutiny than that! We need scientists on the surface looking everywhere for decades before we can even begin to rule out the possibility of life on Mars. And even if there is no current life, we may still be able to re-start the life that was there in the past. It might sound impossible, but you'd be surprised how much certain conditions can improve preservation, and how much information can be gleaned from even a very small sample. We don't even know what life on Mars could look like; it could preserve far much better than what's on Earth. Foot off the gas, guys. That aside, it seems that as typical for astronomers, they're not considering some very important things. Okay, so according to them, there's just barely enough CO2 in the poles to get photosynthesis started, right? Brother, what do you think photosynthesis does? It takes CO2 and turns it into other molecules, all of which is a much, much denser way of storing carbon. If you have "just barelt enough," once those plants and algae and cyanobacteria get going, that CO2 won't be in the atmosphere anymore. Every blade of grass, ever redwood tree, every whale, every human is made in large part out of fixed CO2. And it's not just that - think of the dirt beneath of feet. Much of that is organic matter AKA fixed carbon. How many tons of CO2 is over your head compared to beneath your feet? Seriously, guys. And what are you going to do when you run low of CO2? If you have life on the surface of Mars, is that a good time to bombard the planet with dry ice comets? No, you really should do that kind of stuff first. As far as "increasing the temperature won't increase the rate of atmosphere loss," I assume you guys are talking in astronomical scales, because over here, I was pretty sure that more excited particles tend to escape gravity at a higher rate. You are talking about life here, so please stop thinking that anything less than an order of magnitude is juat a rounding error. And don't compare Mars to Venus; Venus has way stronger gravity than Mars does. And even then, if Mars has just barely enough CO2 to get photosynthesis started, it sounds a lot like that won't produce enough oxygen to support animal life, so what's the point? Please cool it on the egotistical rush to terraform Mars. It's gonna be there for a long time, so let's do this right. Mars probably needs way more CO2 than you give it credit for. Once we are sure Mars has no recoverable biology, then we can smack that planet with space rock after space rock until the planet has what we need it to have. Doing this will also increase the planet's mass, increasing gravity, even if only by a little bit. And in doing this, we might be able to dig a super-crater that could allow us to access and warm the core.

[@perryfaulk9344]

They've recently discovered a magnetic field on mars

[@BarrGC]

@@perryfaulk9344 Ya, but tiny in strength relative to earth's. It's not a big deal either way, magnetic field or no, just look at Venus. Zero mag field yet more atmosphere than we would need for 50 earths

[@Parson2]

What about the lack of a magnetic field due to a solidified planetary core?

[@T.efpunkt]

Mars still has remnants of it's magnetic field. Bad thing is this actually caused mars to lose it's atmossphere even faster.

[@Parson2]

@@T.efpunkt So could we produce an atmosphere faster than it dissipates? If so, how long before it become uninhabitable again? Would it even be worth it for humanity?

[@T.efpunkt]

@@Parson2 i'm not even sure we're able to create a viable atmossphere in the first place, all the plans proposed are pretty hypothetical. But even if, at some point the resources on mars are depleted and the suns radiation strips mars once again. If it's worth it depends on how bad things get back here on earth, but given the timeframes mentioned by the scientists we probably should have started the process a century ago.

[@MarioP9511]

If Pluto is not a dead rock, so Mars is still alive.

[@wb3904]

20:20 they say it will increase when warmed up. And that an atmosphere will disappear in millions of years, so upkeep is at a minimum. That said there are artificial options.

[@CEShoen]

My sci fi project is moving 1/3 rd of venus's atmosphere to Mars....give me credit for the idea never heard it suggested not even in books or other media. 😊

[@gumbercules3925]

We should build out 3753 cruithne into a habitat like a oneil cylinder then move it to mars orbit to serve as the inital colony and base of operarions.

[@peterb9038]

Agricultural aerogel would have uses on Earth, let alone Mars. No need to wait until Mars to develop the technology to the level of mass manufacturing.

[@seanhewitt603]

Nanobots in the atmosphere building nano diamond lenses... Two birds with one stone....

[@silenttitan7636]

If Mars's surface is mainly iron oxide in large amounts could we not mine or introduce aluminum then mix it with the surface making thermite then ignite the surface creating a large amounts of gases and create small factories on all the settlements to boost this effect making giant thermal forges on Mars increasing that atmosphere

[@linz8291]

Boom boom, some people had mentioned to select some Astroid rings throw up to the Martian surface. Then one of the geo-engineering projects - magnetic strip from onland Pyramid seasonal control system has assumed to absorb interplanetary solar array to high attitude region, then underground lakes and water pump are delivering water to Martian surface…

[@francoislacombe9071]

I don't think we should modify humans to live on Mars. We already have difficulties culturally dealing with the very minor differences between the existing human races on Earth, lets not compound the problem by adding far more significant differences into the mix.

[@adambrain8365]

Sorry I haven’t even started the episode, but something in me is screaming “prove it!”

[@Knights_Oath]

If there is microbial life on Mars, if it becomes active again due to a rise in temperature. So we have any advances besides MRNA vaccines to reduce the affects it would have entering out bodies? Would antibiotics work on a exobacteria?

[@1ProsperousPlanet]

If we could heat Mars in just one year, I think our problem would then become how to cool it down.

[@DanielJerome-i9n]

Us humans will be able to harness the power to bring Mars alive , this is our evolution being we are not alone , this is in our DNA we will find out that Has existed much longer than we know , then our studies of future Mars we will discover more unbelievable status of humans

[@TMitraWorld]

Warming up is ok but will Mars be able to hold on to the atmosphere? It's atmosphere is so thin.Can it develop the capacity to do so!?

[@jrlaudio]

No magnetosphere, no substantial atmosphere with lighter elemental gases. How do you propose to create a magnetosphere around Mars to protect the planet from solar stripping?

[@JamesBarry-j7m]

To begin with we don't know if human beings could live on a planet whose gravity is so significantly lower than ours

[@stevedwyer8333]

We would evolve.

[@JamesBarry-j7m]

@@stevedwyer8333 in 400,000 years We evolved from being Africans To being an array of different colors. How long do you think it would take us to evolve to a lower gravitational level? If that was even possible.

[@stevedwyer8333]

Africans became white much faster than the 40,000 years they have been in Europe. I would guess it took less than 1,000 years. With modern genetic technology, we would evolve in a couple of generations. In any case, Mars gravity is still survivable today. But we would quickly evolve to better adjust.

[@RogerK9883]

Do think studying our solar system might teach us to slow down our bio-forming of earth? The bad kind?

[@DavidMorrill]

Any "expert" talking about restoring a planet without talking about restoring magnetic field is no expert at all. May as well talk about Santa Clause. "Expert". Gimme a break.

[@dantess2693]

I believe John covered this on his video on his own channel that covered these methods for Mars. So a separate topic to discuss.

[@mikezizis3725]

Hellas Planitia is an immense crater and the known deeoest point on Mars. There water already exists at triple point. Because it is so deep the air pressure there sustains water as ia solid and liquid and gas.

[@TinShackVideos]

Isn't the reason Mars has no atmosphere is that the core and mantle stopped spinning therefore the magnetic shield dissipated thus allowing the solar radiation to strip the atmosphere away?

[@christophiluslovingchristb5441]

If - Mars had Earth's atmosphere, and could hold onto it, it would be colder than Antarctica being so far out in the Solar System. The atmosphere would need to be able to hold more heat than Earth.

[@chrisk1208]

How will they create a magnetic field?

[@shanepye7078]

Venus is the better choice. It’s closer, can have stations that float on its atmosphere, and if we could reverse its greenhouse effect, we could do that here as well IF it should happen.

[@jimgraham6722]

Venus rotates far too slowly. To make it anything like earth it's rate of rotation would have to be raised from one rev per year to something more like 300 revs per year. Good luck with that.

[@GadreelAdvocat]

Need to set up a heat wind corridor from its equator to it's poles.

[@gueropalma6649]

All this space travel talk and I'm just trying to get an old 80s 4x4 running.

[@leechatt9709]

So, Thinking outside the Box! We are the Goldie Locks Zone! The Moon is right next to us? Why not warm that up. There's Ice on the Poles?

[@Zbezt]

Could try laser cooling on venus to encourage molecular bonding the tricky part is getting ice to form with co2 clouds seeded with glucose

[@dandupaysdegex]

I don't know what Robin's word's worth.

[@gerrypurdy1961]

Where is the video of the speakers?

[@Pisti846]

I have always wondered how Venus could maintain a thick atmosphere with no magnetosphere, but Mars can't maintain an atmosphere similar to ours, which isn't nearly as thick as Venus's. Yes, I know Mars has less gravity than Earth, but even Venus has slightly less gravity than Earth.

[@jimgraham6722]

Carbon dioxide is heavy so doesn't tend to float off.

[@maclivingston9268]

What if there's intelligent lifeforms living beneath the surface of Mars and they dont want you there? Shouldn't absolute surety of non offensive non invasive habitation be settled first? Isnt that a matter of security and universal ethical standings?

[@Raizer_VT1998]

whats the point if there is no magnetic field to generate a proper shield from the sun's radiation?

[@ricinro]

Mars needs much more mass and water/nitrogen/oxygen to make the planet habitable. Perhaps we could steer comets into Mars and attempt to inhabit the planets in a few centuries.

[@UntestedGaming]

Crazy theory, but what if the 2nd and 11th primarchs were entirely made up and implanted into their memories SOLELY to serve as an example of the potential consequences of deviancy. Sanguinius showed that hesitancy when it came to The Red Thirst. But the lesson certainly didn't take across all His sons

[@RogerK9883]

We don't know how to run the environmental system we got. How are we supposed to build another one?

[@muskyelondragon]

Unless you can move Mars closer to the Sun and add vast amounts of water there is no way to warm Mars enough to matter. That is why it is the way it is. Sci-fi dreams about Mars are fun but it's just too far from the Sun.

[@StoccTube]

Nothing will grow in that substrate. There was a biologist on Star Talk who explained why very well.

[@keithmartin2039]

Mars has no magnetosphere among other things. If it were possible to terraform mars far enough so as to be able to even briefly not rely upon breathing assistance it wouldn't last long before the solar wind( remember that magnetosphere thing?) would dissipate that bit of atmosphere into space.

[@bryaninphnx]

100% support this field of study but I hope we can apply some of this to terraforming earth to help mitigate climate change. Cutting emissions to zero is unrealistic in any short amount of time and as we have seen even with this summer in the northern hemisphere that things are getting a lot worse faster than originally predicted.

[@residentgrey]

That is the real cause of the change. They constantly spray the chemicals.

[@residentgrey]

It is also getting better, strangely.

[@vgamedude12]

How about no? We don't know nearly enough to think we have a grasp on how something like that would effect the earth. We have done so much harm already thinking we understand every consequence. Enough is enough.

[@billtev9846]

How about triggering all the valcones on Mars and keep them going for while or converting all the nuclear weapons in batteries for a fusion machine to heat up the surface.
