Everyone realizes that NASA isn't going anywhere, yes?
And more importantly, their goals have been shifted.
No longer will NASA be focused on doing something it has already done. Instead, it is back to the drawing board - focusing on new ideas and technology, with the goal of doing things they have no done yet.
I think that is more important. In the near future, sure, going back to the Moon would be cool. But there isn't much we can do there right now - we don't really have the capability to mine in space nor provide the necessary cargo transport. We don't even have technology that can make use of anything we could take from the Moon, and the tech to build large facilities on the moon is a long while away.
If Armageddon seems near, then watch as scientists scramble to develop a way to save us. But for now, research should be more practical. Practical by means of researching new things that could provide solutions for us in ways yet unknown, not doing something that has been done before.
They have the research for the Constellation program, so it can be revisited in the future should we wrap up what will be underway sometime soon.
But obviously, this will take the focus from the Moon and give Mars a bigger slice of our interests, but more importantly, re-thinking NASA's goals should help them start looking toward new space tech.
I'm definitely down with that. If we can get faster space travel out of this, hell yes. Constellation was going to be more of the same.
