I think Neil DeGrasse Tyson said it best (paraphrasing): It takes less money and effort to fix Earth than to terraform Mars.

I don't remember the source but I also like this quote: Before we worry about terraforming Mars, maybe first we should stop Venusforming Terra.

We have never, even as a proof of concept, been able to develop a closed system capable of supporting mammalian life separate from earth's ecosystems. We assume it's possible based on no particularly rigorous evidence and in spite of our numerous failures to even come close. "Mars as backup" is not a credible plan based on science within even our optimistic grasp.

The technology & social systems capable of doing this would be incredibly valuable long before any permanent mars settlement became feasible so if we can do it we should and then we can see.

I thought this Red Mars was selected for a movie or series a couple of years ago. I guess not, but I think it would make for a good mini-series. But I agree with the author, and I am starting to wonder if the same thing could be applied if we find earth like planets around other stars. I almost think on those planets there could be something in the air or water or dirt that could harm or even kill us if we fond a way…

We might not be the only viable biochemistry in the universe.

True enough, but it's still incumbent on us to understand what other biochemistries are plausible based on what we know. We look for things like organic molecules and planets in habitable zones because we know a lot about the mechanisms that allow them to support life.

And we are curious about alternative biochemistries, I think that drives a huge amount of curiosity toward Jupiter's Galilean moons especially Europa. My worry is that people say "well there might be other biochemistries" as a deepity that kind of checks out from looking at any specifics, unfocusing conversations that were actually more focused prior to the emergence of the deepity.

Classic Neil, always something smart-sounding to say about the wrong thing. It's more about discovery and adventure than fleeing a dying planet. To quote someone that I'm sure is Neil's intellectual superior, "¿Por qué no los dos?"

Because at this rate we'll be lucky to get enough funding and cooperation just to prevent Earth from warming by 4+C, and we need all hands on deck for that.

I mean he had to invent a decent amount of magic technology (the radiation proof tent material for just one example) and purposely not do the math on other parts to make his story work.

IMHO the biggest tell that Elon has never been serious about Mars is that he has been completely focused on the rocket and has severely neglected the actual hard part of the problem: The self sustained habitat for the people to live in. There should be experimental habitats dotting the SpaceX campus with engineers and researchers working hand in hand to solve the problem of scaling up a terrarium to people size. It is not easy. Previous attempts have ended in expensive failures. And those efforts didn't have to be launched on a rocket and landed on a low gravity planet with a very thin atmosphere. Until Elon starts to tackle this problem I know that all of the talk of Mars habitats is just blowing smoke up the asses of investors.

Between the realism about terraforming Mars and the strong likelihood that faster-than-light travel may never happen, is anyone else feeling a bit melancholic? It feels like a possible future has been taken away from us.

I think there are a lot of good futures that involve things being better on Earth

No, it is not a relevant point, at all. There are close to 9 billion people on Earth, more than enough for some of them to focus on expanding human life out into the solar system no matter how small the chance of success. Others can work on the problems 'we created here'. If our predecessors thought like that we'd never have explored the oceans, found new continents, developed industry, took to the skies, made the first tentative jumps into space. Let those who have the means and capabilities to do so explore and 'conquer' those 'new frontiers'. If you insist on solving problems here on earth I'd say get crackin'. If you succeed we'll raise a statue for you and place it next to the ones we made for those who conquered Mars or built that giant wheel in the sky or whatever.

Folks...The US is effectively bankrupt with a 40 Trillion dollars debt in case you did not notice. The US Treasury is just a few minutes away from an economic event, that will force the US government to spend more than 70% to 80% of tax revenues on servicing said debt. There is no scientific or economic case to even go to Mars, much less colonize it. And with the current advances in robotics and automation there is n…

but this is the economic case for it — if things are as dire as you paint them, this is the last chance to get a toehold off-world for at least 3-4 generations, if ever.

> that should something cataclysmic happen to the Earth it would behoove us to have a credible backup plan -- stands.

The day after the asteroid hit Earth would still be better than the best day on Mars.
