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?

It sort of dies out before the first 1.58^-5^ of a lightyear. But be my guest, consign your offspring's offspring's offspring to the consequences of your wanderlust.

Moreover, there's a humongous range of possible radiations, temperatures, elemental combinations, gravitys, pressures. The range necessary to keep a human alive is a one dimensional sliver on the pie chart.
