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?

Science doesn't really happen if we continually ask "Why do this?" Science happens when we ask "Why not do this?"

If we want to be a galactic civilization, we must first learn to live on worlds otherwise uninhabitable. The engineering challenges we must overcome to make that happen will give us the knowledge and experience we need to make it possible to expand past our solar system. This is a very long term advancent, and what we do today is what our offspring will do with ease.

Other than political roadblocks, the final roadblock to galactic expansion is FTL travel. We have theories on how to make it possible, but we are limited to the engineering and knowledge of our time now. Far future generations will be the ones to discover if and how to make it possible, but they need the foundational knowledge and experience of how to live in space.

    Don't worry. We're making Earth pretty uninhabitable these days. We'll get there without ever leaving the planet.
