Musk says Mars settlers are in for a trip filled with survivalism and resource management. Musk name-checked Ernest Shackleton, a famous (and not rich) Antarctic explorer. Last year, Elon Musk caused a stir when he said something provocative, but ultimately correct: there’s a “good chance” the first Mars settlers will die. Now, the SpaceX mastermind, who is dead set on colonizing the Red Planet, is doubling down on that sentiment. In a recent livestream touting his $100 million XPrize reward to whoever can figure out carbon removal, Musk dispelled the notion that the initial Mars journey will be “some escape hatch for rich people.”
