Charles Krauthammer explains the President's Modest Proposal for space exploration. I am an advocate, and Krauthammer puts it better then me:
"Establishing the first human habitation on a celestial body would not just allow for extraordinarily interesting science (from geology to astronomy) and be the locus for extraterrestrial manufacture. It would be -- those without an ounce of romance in their souls are advised to skip the rest of this sentence -- the most glorious human adventure since the Age of Exploration five centuries ago. "
I'm a Sci-Fi kinda guy, always have been. I'm also a "dreamer" (even Conservatives can dream) and have hopes for humanity greater than what can be attained on this world. Man has, is and always will be an explorer. It's time we rediscovered that core human characteristic.
