Ah, satellites yes I agree. I wasn't thinking of this critique against putting things in space, but against manned missions to outer space. I'm all for sending up robots and sending those to other planets to figure out the situation.

I thought that most technically interested folks saw growing into the stars as a worthy endeavor. It is indeed the only way for humanity to survive in the (long) long term. I’m surprised to see that there are so many people here that don’t share that view.

  Space is way, way, way bigger and way, way, way less hospitable than "technically interested" folks on here understand. And being multiplanetary isn't really a great hedge against the types of risks that are existential to a species that's capable of being multiplanetary.

    I can't speak for most people, but I am aware of the size and inhospitality of space, which is why I think we should be be studying and reaching into it now, to give us as much as time as possible to succeed.

      I really don't think you are. Without looking it up: how far away is Proxima Centauri and how long do you think it'd take to reach it given our current propulsion technology? Obviously propulsion will continue to get better and better, but it's a good way to anchor oneself back to technical reality. What's your gut feeling on how long it'd take to reach our nearest neighbor if we were to travel at the top speed of the fastest spacecraft we've ever made?

        I don't know the answers to these questions confidently without looking them up, and if you think that means my opinion isn't worth much then so be it. I have no influence on space exploration beyond being a voting US citizen if it makes you feel better. I believe that Proxima Centauri is ~10 light years away, and that it would take tens of millions of years to travel that distance based on current propulsion. Looks like I wasn't wildly off. I still think that putting humans in space is a worthwhile endeavor, and that the amount we spend on it relative to many other things is not disproportionately high.

        This isn't an appropriate rhetorical technique. For HN. If you want to make a point about the size of space, make it without demeaning the intelligence and understanding of the people you are talking to.

You said "spaceflight", not "manned spaceflight". Manned spaceflight has brought and continues to bring many important advances in science. I would argue that the science dividends of the ISS (which is mainly a research station) are quite worth the relativly low costs. How familiar are you with the science currently being done on the ISS? It often doesnt get heavily talked up, so I suspect your "fringe" assertion is coming drom a place of ignorance. Do you have speficic experiments that you think are a waste of time and money? Manned expeditions to the moon are harder to justify. However, given the track record of technological and scientific payoffs, betting against a positive return, if even from the "exhaust" isn't safe. I do wish that Artemis wasn't our approach though. FYI we spend more money subsidizing fossil fuels than we do on space travel. If we can afford handouts to oil companies that are killing our planet, we can afford to pay for the research that will help save it.

Honest curiosity here, I don't know what a lot of the purpose is!" Which you haven't answered. P.S. I'm not the one who said spaceflight as all, though yes I did interpret it as manned spaceflight, as I just stated
