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?


On the moon, I am guessing some sort of railgun facility. Designate a specific spot on Earth, and you can launch mineral packets to crash there for terrestrial harvesting. Mind, I can see horrific consequences if something goes wrong.
In an old game called Stars!, I used to prepare worlds via mineral deposits to serve as industrial centers. The process also conveniently cleared out the previous inhabitants.
Any time anyone ever mentions extra-terrestrial rail guns, I immediately think of this NPC exchange in ME2:
