Sadly, in tough times, NASA post Cold War is seen as an expensive luxury. I disagree as I think that as a species we must expand past Earth.
Why? Has the human race done anything to warrant such expansion? For all we know, viruses could be laughing their asses off at us.
I'm afraid that all that would happen is we would try and find a way to kill each other in another place...which would REALLY be easy to do in a very hostile environment.
There is so much of this planet that we don't know jack about.
Before we piss money away on space,
money we don't have, I think we should at least explore OUR planet before heading off to find some place else to screw up.
If we can't expand our species to anything but a very temporary existance in the ocean, the chance of doing it off of this planet is zero.
