We require, as a species, the difference between what is safe and unsafe to define ourselves. Be it in darkness or in light, where we are means nothing without the comparison to the other place - where we are not. And thus it is the difference between them that tells us who and what we are.
We often mistake the artificial chemical and psychological thrill of fake edges for the real. In fact we often seek them out as a substitute for the reality of change, growth and exploration. Our minds and bodies help us in this, as they react much the same to this simulations as to the real world.
I do not expect NASA to go out and build settlements and colonies. I do not expect them to give SpaceX all the money needed to colonize Mars. I do not expect them to realize the future of humanity is contingent on harvesting the wealth of the solar system overnight and suddenly subsidize my asteroid mining project.
There was nothing technical or physical stopping us from having moved on from Apollo to a permanent Moonbase, the development of industries in space, and the establishment of the first human communities on Mars. We could have - we can - do it anytime we actually decide that it is our goal, organize ourselves to make it happen, and Just Do It.
I've been doing a few interviews since the loss of the SpaceX Dragon on its way to the Space Station. Each one very quickly questions the viability of what they call commercial space in light of the failure. I tell them space is hard: this is what happens early in a program with new technology.
All the best to SpaceX, Orbital Sciences, and, yes, the Progress teams, who are all working on their own solutions to open the frontier along with Boeing and the rest of the fliers trying to fly, all of whom I know personally share the dream. This isn't their fault; they just want to make things fly.
