Nearly one year ago Chris blogged about Elon Musk's honest estimation of the likelihood of soft landing the first stage of the Falcon 9 rocket for future re-use. After two previous failed attempts, SpaceX succeeded Monday (you can see this video of it here) -- a space exploration game-changer. With recyclable rockets in play, costs incurred by future missions are greatly reduced. A proper reward for a company who initiates outside-the-box alternatives and intelligently takes on a health dose of risk. The logical next question: what is the probability Mr. Musk can send me to Mars in the next 30 years?
