New Way to Warm Mars in One Year | Edwin Kite and Robin Wordsworth

Should we move to mars? Warming Mars in a Year using nanoparticles to make mars habitable.
Ever since Mars was found to be cold and lifeless, scientists have explored ways to make it more habitable. On Aug. 7, researchers from the University of Chicago, Northwestern University, and the University of Central Florida unveiled a groundbreaking approach in *Science Advances*. They propose using engineered dust particles to potentially warm Mars by over 50 degrees Fahrenheit, making it suitable for microbial life. This method is over 5,000 times more efficient than earlier attempts at warming the planet.
Joining John Michael Godier is Edwin Kite, and Robin Wordsworth on Event Horizon as they discuss this revolutionary breakthrough.

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).

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.

[@itstonberrytime]

I genuinely thought this was just AI slop at first. But there's real people talking! I mean, there is absolutely zero chance they could produce a magnetic field strong enough to protect a newly forming atmosphere, but hey, at least it's not just AI slop. Even if the actual people talking are hilariously naive, at least they're actual people.

Generational concept in 1 year?

[@vgamedude12]

The talk about "reverse terraforming" earth really scares me. There are so many instances of man kind polluting and damaging this world with its hubris, and then to try and reverse some effects that we have had were going to do this same thing on a much larger scale? I truly hope it never comes to that.

How many planets has he been to?

[@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.

[@cacogenicist]

Abiogenesis may require wet-dry cycles. If so, no life developed at hydrothermal vents on the ocean moons.

[@JavaLearning]

CO2 reduction done horrible is worse then gain of function as it will reduce the primary type of plants that are food sources and so way too risky. Good idea but can go way off the rails.

[@nickkorkodylas5005]

IMO resurrecting stellar sea cows and consequently revitalizing Beringian seagrass meadows through sea manure is the solution to ocean acidification. I'm not joking.

[@michaelpettersson4919]

Earth or Martian years? The difference are kind of huge. 😉

[@ricardogcbr1676]

The audio is not good

[@ricardogcbr1676]

And the guy talk in a so boring way

[@ricardogcbr1676]

I think its the britsh accent

[@richb2229]

Synthetic biology for mars will be part of the modification to mars. As will atmospheric modification. Much of what is needed is already there (deep aquifers, minerals, and elements) but other resources from comets and meteors will be needed as well.

[@residentgrey]

You don't need anything synthetic. Use the real deal.

[@jimcroft21]

Believe when I see I guess

[@rocoe9019]

Im so sick of this garbage topic!

[@OpusBuddly]

They're going to thaw out something bad. Really bad.

[@kubhlaikhan2015]

Not enough gravity. Figure out how to solve that problem and then I might take "terraforming Mars" seriously.

[@KEISENBERG69]

How to warm Mars? Ermmm, Mars lost it's Magnetosphere millions of years ago. What are you warming it for? Nobody can colonize the surface without that shield to protect them from radiation that WILL kill them long-term. If you're colonizing, it'll have to be UNDERGROUND therefore, where you might as well deploy heating solutions to any underground structure using solar/wind power from the surface, or nuclear.

[@Surgeeon]

Mars has 2 small moons, can’t remember which one is the smaller one but apparently it will eventually crash into Mars anyway. So why not strap a couple of raptor engines onto it and push it onto mars. Essentially Elon musk’s idea but without having to use nukes and it would warm the planet.

[@geofferzh79]

I love how KZbin decided to place further info on climate change lol

[@Libertaro-i2u]

Of course, Mars may not have enough co2 and water to result in Earth like atmospheric pressures and a full ocean.

[@residentgrey]

The planet is covered in rust. Convert it.

[@Dan-dy8zp]

We should not go anywhere near Mars. The moon is so much closer and more reasonable.

[@rfjohns1]

What would keep the atmosphere from just being stripped away into space by the solar wind? Mars has no magnetic field to prevent this.

[@BarrGC]

Time would, that took millions of years, it's not a concern

[@robwalker4548]

It’s not going to as simply stated and it certainly would not look like Earth in one year with oceans.
