Is it really necessary to send humans to those places just to get the knock-on benefits? Couldn’t we do those things directly, without going there?
It seems to me that, today, those who have the money to spend on these endeavors would only do so if there were perceived short-term benefits to themselves. That means they plan to exploit the resources, or increase their own power somehow.
I know the good engineers that make this happen are doing it for the challenge and in the pursuit of knowledge, and I know that’s why we poors support it, but that doesn’t “pay the bills.” What is the motivation behind the money? Why are they really doing this?
That’s a huge reason I believe, hope, that we will never do that. A more efficient and less catastrophic approach is to do some level of refining out at the source and only send back together refined, pure minerals.
…. Although I realize the irony of advocating for sending, say a rod of pure tungsten, back to earth
And more realistically, I have a hard time believing that will ever be cheaper to bring to earth than to mine locally. While there maybe a handful of elements worth it, more realistically you are mining for use in space
