I think it would be pretty cool to be able to go there, explore something new.
But I'm pretty happy with what we have got going on Earth right now. It would be pretty tough to drop everything, and EVERYONE, and just go on a one way trip to Mars. I'd be pretty happy to live vicariously through the people that go there, that would probably be good enough to me.
I was watching a documentary the other day about space exploration and all that. Then I got to thinking how quickly computers and technology have been developing and I don't think it's too far-fetched for us to be living on another planet within our generation. :o
