It's bizarre that an article this detailed would not delve into the likelihood that the word "human" can reasonably be stretched to include "future human-like technically evolved conscious beings who can easily thrive in a Mars environment, e.g. human 2.0, Mars version." In the timeframe we are talking about, this is far more likely than having to worry about life support for humans with current-generation bodies.

As early as 2012 or 2013 Elon was in an interview where he said, instead of humans, sending conscious beings to Mars. Then later he switched to using the word human, presumably because he didn't want to freak people out and complicate the conversations.

    No, it really is not, because that is a quasi-religious belief based on a hope for a particular future event at the end of a long chain of very improbable events.

    (Don't get me wrong: I've been reading science fiction for half a century and I wish it may happen. I devoutly hope it might. I want it to happen. The difference is, I don't think it will.)

    Whereas the article is attempting to be factual.

    • natch 7 months ago

      Your point was well put and would have landed well five years ago, but today the unstoppable (short of global, civilization-ending catastrophe) march toward ubiquitous smart robots refutes that this is a chain of unlikely events.

      The built in incentives for technology to improve will continue after we get smart robots. This will change things.

      In a couple of decades it will be very hard to argue that they aren’t human 2.0 or <n>.0. And if we still insist, they might decide for us. I don’t fervently hope for this but I am very curious how it plays out.

      The opposite view to yours is valid: Us not arriving at human 2.0 would only be possible by a long chain of improbable events. And in this view those who think we will continue as we are (cancer-susceptible meat bags) are the ones taking a quasi religious position.

      • lproven 7 months ago

        No, it's not, and your point continues your faith-based belief.

        I am 57. I've been working in this industry for 36 years. The computer world is no closer to machine intelligence today than it was in 1988 when I walked into my first job. It's no closer than in 1981 when I touched my first microcomputer.

        LLM bots are not in any way intelligent, but they do expose a type of flawed non-analytical thinking in humans that is easily persuaded that a machine is intelligent if it can emit coherent sentences.

        I think you are totally wrong and that this will be abundantly apparent in a decade, perhaps in half a decade. The next few years will usher in the latest AI winter, just as they did a generation ago and a generation before that.

From today's perspective, sending people to Mars will be, more than anything, part of a new space race.

  • nine_k 7 months ago

    A race suggests the presence of at least two participants that are running at the same time. As of now, I only see one contender with any chance to make it to the start line.

    Maybe in 30-50 years there will be a race to build and sustain Mars bases, and attain some control of the territory there.

      China just built their own space station and is racing the US to be the first to put boots back on the moon. Then there's the militarization of space and everything that's been going on there. The US wouldn't have its current moon plans and timeline if China wasn't also trying to put humans back there; it's all been timed to beat China by a year or so.

      • nine_k 7 months ago

        Certainly there is a space race, but it's mostly around Earth and somehow around Moon. I don't see anyone but Mr Musk seriously trying to settle on Mars, so no race there.

        OTOH the Starship is also going to be a major player in the Earth and Moon business. Even just on Earth, it's basically capable of landing a few hundred tons of cargo and passengers anywhere on the planet within an hour or so. Or will be, once the landing gear is attached. It may have interesting military consequences.

What do we have to gain by going to mars?

  • jasfi 7 months ago

    The objective would likely drive lots of improvements to science and engineering.

    Mars itself is very inhospitable to humans.

    • nine_k 7 months ago

      Mars is extremely hospitable to humans, compared to almost every other planet except Earth.

      Mercury: tidal lock to Sun, heavy solar radiation and solar flares up close, complicated orbital movement, low gravity, basically no atmosphere. May be habitable underground in particular belts with reasonable temperatures.

      Venus: a runaway greenhouse effect, metal-melting temperatures and colossal pressure on the surface, colossal never-clearing clouds, very strong winds, sulfur and chlorine abound in the atmosphere. Could be habitable using artificial islands floating in the upper atmosphere where the temperature and pressure are comfortable. At least the gravity is close to that on Earth.

      Jupiter is not habitable by itself, just due to the very strong gravity. Various moons of Jupiter are all pretty cold (though some have liquid water under the surface), and at his distance from Sun, the amount of sunlight reaching them is rather small, even when reflected by the giant disc of Jupiter in the sky. It's cold, solar power in impractical, uranium and thorium are not apparently abundant.

      Saturn: see Jupiter, only even farther and colder.

      Neptune: see Jupiter, but even without serious moons.

      Pluto / Charon binary: not even a planet. At this distance, Sun is but another star in the sky.

      Compared to these, Mars, with its conditions that resemble Earths's polar regions over large swaths of the surface, acceptable distance from Sun, serious amounts of water (as ice), acceptable gravity, acceptable amounts of sunlight, and relative closeness to Earth looks not that bad at all, and basically the only practical candidate for an autonomous, self-sufficient world.

      • jasfi 7 months ago

        Just because Mars is better than the others doesn't mean its good enough as a long term habitat.

        People would have bone density problems much sooner in life, as an example.

        • nine_k 7 months ago

          There is a price you have to pay to make a whole new planet your own. The choice of accessible celestial bodies is scarce, to say the least. A long-term colony, and by this a mean centuries and many locally born generations, will certainly uncover a large bunch of problems, and develop a number of adaptations, possibly including eventual genetic changes.

          • jasfi 7 months ago

            I had a similar reply to someone else: by the time we can adapt to live on Mars, decades away at best, traveling there will be the least of our worries. Glad to be proven wrong, of course.

            Maybe we can try and terraform it in the meantime.

    • K0balt 7 months ago

      It is very inhospitable to biological humans.

      There is a decent chance that our present biological basis is not congruent with the future of humanity. Mind-extension into synthetic cognitive structures is not as far fetched as it seems- we already extend our consciousness using machines, albeit with a very poor interface.

      It is foreseeable that we will come to understand the nature of sentience - after all, many simpler organisms exhibit sentience- and beyond that it seems to be a scaling problem, which are inherently tractable.

      If we can improve the interface between biological computation and synthetic computation, it will likely become possible to extend sentience across that divide, barring some kind of spiritual phenomenon or “magic “.

      If we don’t shoot ourselves in the foot too badly, it is foreseeable that we may make very substantial progress in this direction over the next century. Establishing a toehold on mars during that century will be a huge strategic advantage.

      The problem with “people these days” is that almost no one thinks a multi decade project is worth doing. If everyone waits for the future to “arrive “, the future you end up with is just driven by quarterlies.

      The most important accomplishments will be remembered for centuries. If you aren’t working on one in some capacity, what are you even doing with your life?

      • jasfi 7 months ago

        If we can pull off synthetic bodies for our consciousness, then by that time going to Mars will be a walk in the park.

        But I think you underlined the issue of timelines. Yes we can technically go to Mars in only a few years, but people living there permanently is going to be beyond my lifetime. Unless some people are willing to drastically sacrifice their health.

        • K0balt 7 months ago

          It’s not so much synthetic bodies as synthetic brains. Once we can move into thermodynamic neural systems or something similar in effect, -anything- can be a body. You could be a spaceship, or a power plant, or an anthropoid robot. I would imagine that one would need enough sensory diversity to keep from going mad, But I would imagine that corporeal flexibility would be one of the major perks.

    > What do we have to gain by going to mars?

    There's an assumption in the question that we are going to Mars.

    We aren't. It's the individuals who own the resources and money to implement space flight and Mars colonisation that are going to Mars. We don't get a say and our opinion doesn't really matter, unless we also happen to own aerospace companies. As such what we might have to gain depends on what the men in the arena choose to share or sell from the results of their efforts.

      Its basically impossible to finance a meaningful try at colonizing mars without national resources

      • Asraelite 7 months ago

        I don't think it is. The hard part is building Starship, which is being done anyway.

        After that, it's conceivable that the cost to travel there will eventually fall to a few million or tens of millions of dollars per person. At that point, a handful of rich people could drive enough demand for the development of colonization technology that it becomes self-funding.

        • michaelmrose 7 months ago

          We can't live on mars without living inside massive radiation shielding probably underground. There won't be enough industry this century for Mars to be self sustaining if we start tomorrow.

          For the non-scientist living on mars would be living in a cave worse than that enjoyed by most poor people in absolute boredom 99.5% of the time.

          Your martian adventure will cost an appreciable portion of a billion dollars, include a return ticket, and continual support from home. It will be a very high cost ammortized over few units and it will never be self funding.

        That's a separate point: Citizens don't really get a say in how national resources are deployed, though the theatre of elections certainly makes them think they do (Recall that dude at Davos who said, "There are 150 people who run the world, all of them are men, and none of them are politicians"?).

        The point is: you and I, unless we own private aerospace companies, don't get a say and don't matter in the question of "why Mars".

        We'll certainly be allowed and encouraged to "make your voices heard" and many, including politicians and "representatives", will protest about the trillions of "taxpayer dollars that could be put to a better use". But the people who are doing the innovation and taking the most risk with their own capital will decide.

        • michaelmrose 7 months ago

          We already admitted we were talking about trillions eg almost entirely our capital by any definition.

          The people doing the most innovation will be the scientists who be compensated a tiny fraction of the money earned by the capital.

          The people taking the most risk will be the people going.

          Again the capitalists will be contributing little and risking almost nothing mostly their position on a scoreboard.

          The person driving the school bus risks more and contributes more than the parasites.

              You have condescended to me but you haven't explained how I'm wrong and I don't think I am. If so pray tell.

              Money as a fundamental unit of value outside of economics leads to nonsensical conclusions like taking a money guy who presently employs a stable of geniuses who themselves sit atop the result of man millennia of labor by singular irreplaceable people and assigning credit to the current idiot who owns the works.

              It leads you to imagine that owning a hundred billion is as valuable a contribution as a million teachers or that someone who risks 90% of his fortune by ceding a bigger piece of the economic pie to another billionaire and thereby downsizing to fewer trips to space is somehow risking a billion times more than someone actually risking their life.

              It's like listening to a psychologist try to understand the evolution of galaxies via their domain knowledge.

              Capitalism is a method to allocate resources within a society it offers no meaningful truths about it. It is on the whole a massive failure only slightly less stupid than prior iterations of central planning.

              Back on the topic of mars. It is fundamentally absolutely useless as a second home for man. It is at best a place where a small number of people can do interesting science. There wont be a meaningful number of people there because the entire idea is fundamentally flawed.

                Here's the bottom line so you can write another thousand words coping:

                Men are going to Mars. Men who own or run aerospace companies will make it happen. You aren't one of those men. Your protests and pontificating don't matter.

                The costs will dwarf any projects humans have pursued so far. I hope the long term costs are in the trillions so that a quadrillion dollars of wealth is created!

                To the extent that taxpayer dollar matter, it will be because nations don't want to miss out on the investment, not because they are needed.

                Perhaps you haven't made your 1st million yet, so you really don't know how to create wealth or build substantial projects. It doesn't start with taxpayer dollars.

                  For this specific one, I will merely quote the words of a wiser person than I.

                  "Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small, green pieces of paper, which is odd, because on the whole, it wasn't the small, green pieces of paper which were unhappy."

                  If you think it's about money you haven't understood the real issues.

                  Money is nothing more than a symbol, just like flags, and nations, and gods. Symbols for things that are not actual real things.

                  Symbols do not matter. Reality always beats symbols. Reality continues after any entities that can create and manipulate symbols cease to exist.

                  Focus on reality. Try to ignore symbols.

                    And aside: People who think money is an actual limitation often sound to me like people who've never issued shares or been in a conversation with a municipality issuing debt. Money is literally not an impediment and I don't think money is an issue except to the extent that I was dragged into an argument about it.

                    You'll recall I spoke of "wealth", as completely distinct from "money". Of course you already know the distinction as you've alluded to it in your own post.

                  I want a scientific mission to mars I hope doing so pushes science and engineering know how forward.

                  Going to mars on a larger scale is presently nonsense because beyond the science there is no reason to go there. There just isn't anything of exploitable value there.

                  We can't at this level of technology teraform mars nor live there without massive radiation shielding eg live like rats underground 99% of the time.

                  Furthermore every aspect of our technological civilization is heavily dependant on a long chain of products with their own deps stretching back in a massive graph.

                  Any such endeavor would be incredibly costly per person, yield little more than hosting a half dozen people, and require a constant input of goods from home without which everyone does.

                  This isn't a frontier town because its too expensive and it doesn't have things that can enrich home base for less than cost on acquisition.

                  It isn't a backup plan if Earth dies because exploding a 1000 nukes would leave the bombed out husk 1000x more livable.

                  Its not a second earth because we can't teraform it at present level of technology.

                  It won't create a dragon hoard of wealth because there is no reason to believe it will create any.

                  Its just a science mission like the ISS. It does actually start with government money because nobody has multiple trillions to spend on something that won't create wealth because why would it.

                  Please refute something of what I said.

                  Let's start with how a large scale colony is going to be viable and earn money.

                    Here's thing. If you answer the questions you raise, you win the prize at the next frontier. That's what innovation is about. You can be given infinite amounts of money anywhere in the world if you present solutions to questions that other men can't figure out. That's the game.

                    But you don't actually want to answer the questions: "how do we colonize Mars", "how do we build a 1M person base on the moon?" You want to moralize about your low expectations and treat your lack of imagination as a virtue. I categorically refuse to play that game. But good luck.

                      There isn't anything on Mars that would warrant a city. It isn't merely inconveniently located like your dairy farm its amazing expensive, unlivable, and worthless outside of science which is why you want scientists studying it but its pointless to build a city there.

                      Its not about how we build a city there its about there being no reason to do so this century. It was fucking trivual to answer that question for Every other frontier and the dairy farm because however remote the farm it had soil and an atmosphere.

      This is one of my reasons. I also believe that compared to the Moon, Mars is more likely to both give crewed spaceflight and human habitation of other bodies the big boost it needs and make it more of a permanent fixture — the Moon’s relative convenience is a problem in that it makes it just as easy to mothball as it is to get to. Lingering too long on the Moon as the focal point brings substantial risk of backsliding into Shuttle-era stagnation.

        Can you explain your thinking? Why would Mars be harder to mothball?

          It’s a result of the much higher level of commitment required to undertake crewed Mars missions. You can’t lean on Earth being nearby and contingencies have to include e.g. uncrewed resupply missions failing… it’s the sort of thing you have to go all-in on, after which pulling out is costly and looks stupid.

          By contrast, backing out of the moon is comparatively trivial. At worst it’d take a couple weeks and the expenses quickly lost in the noise.

          With Mars, there’s also the possibility of a “Wild West” element once things are established enough where groups of people simply refuse to return and cutting off support from them would have really bad optics.

Phew. The pessimism here is kinda... exhausting. But frankly I don't have any material objections

""" The Mars Religion

When you hold on to a belief so strongly that neither facts nor reason can change it, what you are doing is no longer science, but religion. So I’ve come to believe the best way to look at our Mars program is as a faith-based initiative. There is a small cohort of people who really believe in going to Mars, the way some people believe in ghosts or cryptocurrency, and this group has an outsize effect on our space program.

At NASA, the faith takes the form of a cargo cult. The agency has persuaded itself that re-enacting the Moon landings with enough fidelity will reward them with a trip to Mars, bringing back the limitless budgets, uncomplicated patriotism, and rapt public attention of the early sixties. They send up their rockets with the same touching faith that keeps Amtrak hauling empty dining cars across the prairie, dreaming of the golden age of rail.

Outside of NASA, the Mars faith shades darker. It is part of a transhumanist worldview that holds mankind must either spread to the stars or die. Elon Musk, the Martian spiritual leader, has talked about the need to “preserve the light of consciousness” by making us a multiplanetary species. As he sees it, Mars is our only way off of a planet crawling with existential risk. And it's not just enough to explore mars; we have make it a backup for all civilization. Failing to stock it with subsistence farming incels would be tantamount to humanity lying down in its open grave. """

    Something that’s frequently lost in the discussion I think is that in the long term, Mars is a stepping stone.

    While proponents think that Mars should be permanently inhabited and have cities, the larger point is to light a fire under the development of the technologies and techniques involved in crewed spaceflight and human habitats beyond Earth’s gravity well. Mars does this better than the Moon does because it has a higher baseline level of self-sustenance due to its much greater distance, and so if you get to the point that getting people to Mars and having them live there long term is no big deal, you’ve also essentially made humanity a proper spacefaring species — we’d no longer be so tied down to LEO and could have substantial crewed missions traversing the solar system and beyond.
