Yesterday, billionaire tech entrepreneur and noted late guy Elon Musk unveiled his hotly-anticipated plan to send humans to live -- and die -- on Mars. And not just a few humans: A lot of them. In a talk that wavered between overreaching science fair presentation and straight-up science fiction, Musk described sending fleets of spacecraft, each packed hundreds of colonists, to live on a dusty, airless wasteland that we're apparently going to fix up with nuclear reactors and artificial magnetic fields.

SpaceX has been talking up its Martian travel plans for a while now, but we still don't know how it intends to get (or survive) there. As of yesterday, however, it's cleared a major hurdle: The rocket engine it will use to get to the Red Planet just fired-up for the first time.
