Clearly written, concise, educational and endlessly inspiring. The most interesting part for me was about the Mars economics and how our iPhones or whatever we will have then may one day be realistically mass manufactured on that planet, from metals harvested on asteroid nearby. Insane! Much recommended.

At first I thought this was an advertisement for Elon Musk's SpaceX plans, but it seems that the author is reporting from the only viable source at this time for how to colonize Mars and why. I wish I had $500K to be able to move to Mars or at least be on the first flyby trip for couples - what a great marriage retreat!
