The most interesting part of this article is how it reframes Mars terraforming as a future civilization problem rather than just a space technology problem. Warming Mars or adding atmosphere sounds simple in science fiction, but the scale would require centuries of energy, mining and planning. That makes smaller enclosed habitats, domed cities or underground settlements seem like the more realistic path for the near future I think. I also think this raises a good question for the future – will humans try to make Mars Earth-like? or will the future of space settlement be more about building artificial Earth-like environments in places that remain hostile outside?
Gonna be hard to fit that into business quarter to quarter reporting
Turns out changing the climate and environment of an entire planet is an epically difficult project.
Who knew?
Something I appreciate is and the board game terraforming mars, which is tremendously enjoyable, if I recall correctly the turns are referred to as „generations“. They capture that time scale pretty reasonably.
Honestly I don’t think this is the thing that will ever happen, the cost will be too high. But predicting the future has ever been a Fool’s errand, and maybe at some point in the not to distant future cost becomes irrelevant. Just cuz we’re stuck in highly capitalist motif with an energy limited society right now does it mean it has to be that way forever.
Anyone with any sort of science background could tell you that
Actually a good article with realistic understanding of the massive resources required.
Full terraforming isn’t practical, but limited para-terraforming might be achievable. If you can give Mars 2% of earth’s atmospheric density then the presure in very low lying areas is just high enough that astronauts won’t require a pressure suit just arctic clothing and a rebreather/oxygen source.
The claim in the headline is obvious to anyone who pays attention. Aside from that, the article is a decent overview of proposed terraforming strategies and also references the paraterraforming concept, which I always like to see.
Mars have always been a pipedream. Mostly because of the low gravity.
Mars isn’t possible to terraform until it’s core warms up and gets spinning faster. Without it, any atmosphere introduced will just evaporate off. Just introducing industry, smashing some ice comets is imaginable. Restarting a planetary core isn’t. Not happening soon
Send the Trillionaire to Mars already so we can get rid of part of our planet’s problem.
It would be so much simpler and cheaper to live in Antarctica than on Mars.
Has anyone thought beyond the fever dream of colonizing mars? Say we get the magnetic field up again, say we have tech to sustain a population working on terraforming a planet half Earth’s size for the next hundred+years.
Mars is technically in the habitable zone, but just barely.
Living on Mars will be like living in perpetual winter. Maybe a thin band of temperate, somewhat pleasant weather around the equator. Who wants to live in a place like that when we already have far fewer people living in such conditions here on Earth?
So basically, we’re talking about an industrial revolution on a planetary scale, just to get Mars to a point where it *might* be habitable. That’s a hard pill to swallow when you consider the resources and time involved.
It is not possible to terraform Mars. Going to Mars with humans is not possible. It is not survivable because of the radiation and we don’t have a material yet to protect humans from it. Just going to Mars is a death sentence. That’s why Elon keeps changing SpaceX „goals:.
Say 300 years is the blink of an eye in astronomical timescales.
Even a thousand.
We’re just not equipped to understand the magnitude of time given our very limited lifespans
Neil deGrasse Tyson views terraforming—specifically of Mars—as a monumental but ultimately hypocritical engineering challenge. He argues that if humanity possesses the technology and resources to completely alter a harsh alien world to support human life, we would have the exact same capabilities to restore Earth’s.
It would only take centuries because we haven’t done it before. If we successfully did it on one planet we would be able to develop a proper method to it that is more efficient, allowing us to do it very quickly on a variety of other planets. The problem with humanity is that we are so interested in ourselves and what we have going on with our tiny world that we fail to realize the long lasting benefits of going into space. If we would stop fighting amongst ourselves and care more about the bigger picture then we could shoot millions of years ahead in advancement within just a century or two.
Are you telling me this hypotical engineering project that dwarfs humanities entire industrial output by a factor of quintillions might be unrealistic
Also this one thing that people tend to forget; there is no magnetosphere on Mars to protect from solar radiation like Earth. A better bet would be Ganymede.
Can’t even maintain the thermostat here and want to go try and make a whole new planet….. idiots.
Something something planting a tree you won’t be alive to see reach full height, or something.
If we start sending astronaut construction battalions now to start building a habitat, when they die from radiation exposure they can be composted. Fast forward 300 years and a million missions with 1000-person crews making the voyage,and the number of composted bodies might make enough ferile soil to grow food for a small, permanent colony.
good luck doing anything without much of an atmosphere or magnetosphere
Projects with little chance of reality still put a great deal of money into the pockets of a select few people. The amount of resources that would go into that while we neglect our own planet so drastically shows how obtuse and ignorant we are, while some people get rich leading us down the primrose path. It’s an entire planet with little atmosphere and no magnetic shield against radiation. It’s cold, barren, and maybe the only thing going for is that it’s another place.
That would be fast. Usually nature take millions years to make that change.
