5 times Elon Musk blew our minds with his Mars plan

SpaceX CEO and founder Elon Musk on Tuesday laid out his plans for colonizing Mars and then sending humans out among the stars. But buried in his announcement were a host of fascinatingly specific details stripped straight from sci-fi novels. He casually mentioned TRANSFORMING AN ENTIRE PLANET. All those people would need places to live and work, and as part of that process, Musk suggested we could make oceans and an atmosphere if we could just "warm Mars up." Warming the entire planet would cause its ice to melt, releasing water vapor and helping create more of an atmosphere.
