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

However there are a lot of entrenched interests that would be harmed by any large-scale attempts at fixing earth. Even if you paid for it out of your own pocket and brought your own engineers, your attempt at fixing Earth would face strong opposition. Meanwhile barely anyone would oppose your attempt at improving Mars.

The article is however spot on that terraforming Mars looked easier 30 years ago than it looks now, with all the new knowledge we have from Mars rovers. Now any "realistic" plan would be millions of people living in pressurized habitats and venturing out in suits, not billions walking on the surface in t-shirts. Closer to what we see in The Expanse than to what we dreamed up in the 80s and 90s

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.

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.

  • Classic sarcastic ironically detached drive-by HN comment. Where is the money going to come from to do both? Every dollar spent on discovery and adventure could be invested in Earth based projects.

  • > "¿Por qué no los dos?"

    Because right now we're not investing in fixing Earth but seriously investing in an infeasible Mars mission.

The only advantage of terraforming Mars is that if you do it wrong you're not making it worse for anybody that lives there. It could be a good test bench if it wasn't for the elephant in the room: it takes a very long time to terraform a planet

  • There's also the tiny detail that we are technologically incapable at the moment.

    • Well, that's why it's a good idea to have a place to try things out, so we can learn.

      But of course, doing that is highly impractical for many other reasons.

Of course that is true, every Mars enthusiast will agree. Not a single person is saying to leave Earth behind to rot. Agree with Mars proponents or not, but at least don't argue against strawmen. Their actual argument treats Mars as a backup strategy for humanity and a science outpost
