In The Overview Effect, I proposed a "Human Space Program" that would be global in scope, and would transcend all national programs. It would last for a millennium, and would be a "central project" designed to unify humanity in a common purpose, i.e., exploration of the universe.
There are signs that this kind of thinking is now seeping into the global consciousness, and I want to report on it in some detail in future posts. I have read several references to NASA/ESA cooperation, and to a proposal by a thought leader in India for a new, global vision of space exploration. The Augustine Commission is also clearly pointing in this direction.
For now, suffice it to say that it is very exciting to see this taking place. I hope we can nurture this new thinking and make it a reality.
