Elon Musk: we must colonise Mars to preserve our species in a third world war

Humans must prioritise the colonisation of Mars so the species can be conserved in the event of a third world war, SpaceX and Tesla founder Elon Musk said on Sunday. "It's important to get a self-sustaining base on Mars because it's far enough away from earth that [in the event of a war] it's more likely to survive than a moon base," Musk said on stage at SXSW – just days after Donald Trump announced plans to meet the North Korean leader, Kim Jong-un, in an attempt to defuse rising nuclear tension. "If there's a third world war we want to make sure there's enough of a seed of human civilisation somewhere else to bring it back and shorten the length of the dark ages," Musk said, responding to questions from his friend Jonah Nolan, co-creator of TV show Westworld. SpaceX is working on a vehicle that will take humans to Mars, a 100-metre ship codenamed the BFR (Big Fucking Rocket). But building a colony would require "tremendous entrepreneurial resources", Musk said. He also countered the suggestion that Mars might be "some escape hatch for rich people" by highlighting the risks of the mission: "It will be like Shackleton's ad for Antarctic explorers: 'Difficult, dangerous, a good chance you'll die, excitement for those who survive.' "There's not many people who will want to go in the beginning," he said, adding that over time the Red Planet colony would be hospitable and have "great bars.
