It looks like SpaceX is gearing up to colonize Mars, with the first flight targeted for 2018 (the next time the Red Planet is close enough to give us an orbital shot at getting there quickly). That will just be the first unmanned test flight and attempted non-exploding landing, if they can even make that incredibly close deadline, but damn, I am excited! My favorite article about it so far is the one put together by Space Flight Now, who always do a great job of analyzing all the pros and cons of a proposed space mission. The Dragon 2 spacecraft could possibly deliver 4 tons of supplies to mars per launch (you wouldn’t want to use that craft for the actual mission, since the crew capsule is the size of an SUV), building up to enough food, water, and equipment to make the project viable. No word on when the first humans would head that way quite yet, but I expect them to make some comments once we see how the initial mission goes.
