Manned mission to Mars is a fad.

But it is important fad just like space mining.

We as humanity have to believe we are not in zero sum game to stay decent…

Unfortunately last years are showing us how ugly it is with rare earth elements, energy etc. It is also showing what you wrote is true. No one really believes that we can affordably space mine for rare earth and no one believes in Martian colonization that would bring tangible benefits.

For anything to become reality, the 1st step is be able to imagine it.

Also a big problem can be attacked by solving a small part of it, see what's left & repeat until remaining bits are easy.

Over time, what used to be 'impossible' becomes easy. What matters is deciding what to focus on for the foreseeable future, and spend resources wisely. See eg.:

https://en.wikipedia.org/wiki/Interstellar_travel#Wait_calcu...

Yeah a human mission to Mars, colonizing the clouds of Venus, asteroid mining or Dyson spheres may not be achievable now (if ever). But exploring the problem space, or having a good look at the required engineering, is. And may be cheap as well.

If you held the same logic back towards the beginning of humanity then we'd all still be wandering about the woods poking each other with sticks. Most people don't believe things are possible which is probably some sort of evolutionary thing. A society full of people with their head in the clouds probably wouldn't work so great, but humanity would also stagnate without at least some people looking to the stars.

This could very well be why planned economies seem to struggle with innovation. People being able to devote significant resources to endeavors, that might not make sense to most, is how you get lots of failures, and the occasional revolutionary successes. Do everything by committee and all you get is a shinier version of what you had last year.

You went false dichotomy on this.

I say fad because I don’t think it will happen in my lifetime and I would say 90% it will never happen.

But that 10% possibility of it happening is important or 0.01% of possibility it happens in my lifetime.

It is important that people believe it is more than my numbers. It is important to spend money and work towards that goal.

Because alternative is much more terrifying.

With the power of hindsight many decisions look obvious. But many others look silly. For every "discovery of the Americas" there were thousands of expeditions that fizzled out in a worthless desert, middle of the ocean, dead end cave.

The argument that "progress always needed bold steps" can lead into dead ends too. Past experience isn't enough to justify future steps without additional evidence. Exploration and learning are always good reasons but if you jump to the "it's good business" step before knowing all you can reasonably know, it's probably a fad. It's shooting in the dark. It could still hit the target, or it could miss. You only really know if something is a fad or not with hindsight.

It's hard to say with certainty today whether Mars is a viable target for colonization in the long term compared to other places like Titan or even the Moon. Before you drill for oil you do a lot of exploratory activities. If those bring back solid positive results then you go for the full blown thing. Before you launch a business you build a business case. Did anyone provide a solid business case and exploratory evidence for why "going for Mars" is the viable future?

As far as I can tell it's not scientists pushing for colonizing Mars. All we have to go on is the push from a man widely known to pump up the value of his own companies (which this would do and then some) by repeatedly making sweeping promises he failed to keep.

This [1] is pretty much exactly what you're looking for. Zubrin is one amongst countless voices, of all back grounds - certainly academic included, pushing for Mars colonization. Even as far back as the 60s NASA, under Von Braun, had drawn up extensive plans for settling Mars. This was all cancelled by Nixon, in large part because he was worried that a catastrophe under NASA would look bad on his political career. If he only knew what was coming.

Musk has become demonized mostly because of his politics. He's made bold claims and overwhelmingly fulfilled them in space. For instance there was a time when something we now take for granted - autonomous landing reusable rockets - was deemed impossible by the powers that be. They were even taunted by Boeing et al along the lines of 'yeah, we tried that long ago - the economics don't work. it's cute to see you having a go at it though.'

He's also brought the price to get things to space down multiple orders of magnitude relative to the Space Shuttle. And similarly before him, electric vehicles were glorified go-karts for virtue signaling hipsters. Having any public political opinion in a country as divided as America is going to make a whole lot of people hate you, but I think the efforts to try to marginalize what he's done are a mixture of silliness and ignorance. If he died tomorrow he'd already go down as the Edison of this generation, and there's yet many a decade remaining for him to cement what may be the ultimate legacy of the first man to make humanity truly multiplanetary.

What about the countless voices, academic included, against it? It's not whether someone thinks it's a good idea but if we have a reasonable consensus on it. 50/50 is a coin flip, not a "peer reviewed" conclusion. It took the blink of an eye to realize putting things in orbit is greatly beneficial. We've been looking at Mars from all sides for decades and the business case is yet to be clear except mostly for people making money by selling you the idea, or the book.

> Musk has become demonized mostly because of his politics. ... He's also brought the price to get things to space down multiple orders of magnitude relative to the Space Shuttle. And similarly before him, electric vehicles were glorified go-karts for virtue signaling hipsters.

Let's not make this the core of the discussion, my objection to him isn't ideological. The companies he has led have a history of fraud, misinformation, and lies. Tesla is the poster child of this. If I can pick just the most obvious examples, FSD has been promised just around the corner for close to a decade now and the recent retroactive change of the contracts really drives the fraud home. Solar Roof was a sham from the start. Boring Company, sham. See how I'm not listing just a "normal" business failure, like xAI failing as a frontier AI lab. Not everything is destined to be a success. I'm just mentioning the things that were overtly lies told for money. SpaceX is probably successful because by all accounts Musk left the leading of the company to the CEO. His history of lies to enrich himself legitimize the attitude to start with the baseline that any wild claim that could enrich him is a lie and wait to be proven otherwise.

For a hammer everything looks like a nail, so for Musk everything is in space. As it happens, he's one of the few parties in the world with easy access to that resource, and acts as a gateway for almost everyone else.

I'm not losing or making money on his success so this for me is just a matter of common sense. If someone lies as often as he does, it's "shame on me" to still assume truth until proven lie.

Well then you loop back to where we began. You implied nobody had made the 'business case' for Mars, as in something tangible. That's been done repeatedly, to quite a high standard. Now you're back to claiming well what about some sort of consensus, but again do everything by committee and all you get is a shinier version of what you had last year. It's easy to critique things, even things that are completely and absolutely sound - before people know that.

For instance here [1] is the NYTimes claiming that human flight would be impossible, published just about 2 months before the Wright Bros achieved human flight. Incidentally they also said space flight would be impossible, and were actively patronizing towards the concept. They felt that any child with a basic understanding of science would understand that there's nothing to 'push back against' in space, so spaceflight simply can't work. Until that's proven wrong by actually doing it, some might actually think 'wait that's kind of reasonable - omg maybe it is impossible.'

As for Musk, you're simply assuming malice when e.g. everybody thought full self driving was just around the corner when he made his claims about Tesla bringing it to market. It's kind of the same way that today everybody thinks that in a decade LLMs will be replacing knowledge workers left and right. It's just extrapolating outward from a trendline that exists at one point in time. But it may well be that in a decade we're still predicting that in a decade LLMs will finally be there. Or maybe there will be some revolutionary change, as promised by by all the people pushing LLMs. If it fizzles out, I wouldn't jump to calling them all fraudulent hucksters.

It wasn't that long ago that HN had a spirited discussion about how data centers in orbit could not possibly work. But it looks more and more like Musk is going to deliver.

>No one really believes that we can affordably...

People said that about everything. I wore a $10 silk tie to work today and ate toast with a $1 Avacado on it.

Marco Polo would shit a brick if he saw Interstate 90.
