Elon Musk probably writes "try to save the world" at the top of his to-do list every day, above running companies that are revolutionizing energy, transportation, and space travel. In the next decade, he's hoping to pioneer humanity's next great adventure: Interplanetary travel, and colonization of other worlds.
In the most far-field scenario — where humans are surviving and thriving on a planet other than Earth — those challenges include the property politics of camping out on interplanetary soil: Who presides over judging Martian crime? Who's in charge?
But before they even get that far ahead of themselves, SpaceX will need to answer more pressing issues, like how to keep hydrogen tanks from going boom and how to keep us fragile, fleshy humans from starving on the trip or dying of radiation exposure once we're on the surface.
All of these questions Musk and team hopes to solve by mid-2020s, when the Interplanetary Transport System aims to haul 100 humans and/or 310 metric tons worth of cargo to the Red Planet. It's still not clear if there are ulterior motives to get our asses to Mars and beyond.
Ahead of the keynote, Musk treated his followers to a characteristically candid behind-the-scenes of the rocket engine that'll blast this whole thing off the ground in the next decade, tweeting photos from Raptor's first firing test.
