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?


Haven’t read all the responses, but in case nobody’s said it: the moon will never be easily terraformed into a stable environment, so the primary reason for moon habitation, aside from telescopes which require no fuel for orbital maintenance (and have no atmosphere with which to contend), is that the moon is a significantly easier place both to construct and launch rockets, so if we can get asteroid mining going, a moon base would allow significantly increased accessibility for rocketry for other missions.
For Mars, I figure it’s twofold:
As someone pointed out, however, the current society is so focused on funneling wealth and power to only a few prime exemplars of the Dunning-Kruger effect, that to attempt actual colonisation when they are the ones who’d control the colonies would be violently, unbelievably stupid and be even more likely to lead to total extinction of life on Earth
