I am rooting like crazy for the Mars project. The problems of establishing a human colony and keeping it alive can be overcome given current technology and the pace of advancement in the various necessary fields. The issue is making it cheap enough to get it there, which is not progressing fast enough for the given deadline.
I guess I am biased - Elon Musk is an utterly single-minded, even possessed, visionary. Just one example is his journey to overcome the problems with production of the economical Tesla model. He is pursuing an ecologically sane solution for our transport problems and tackling the issues step by step, on a scale that boggles my tiny mind.
I vote for this one:
"Hey, checkkit out my bra, it looks like the Karoo!"
