Elon Musk, age 47, told “Axios on HBO” that he sees a 70% chance that he’ll live to ride one of his SpaceX rockets to Mars. “I know exactly what to do,” he said. “I’m talking about moving there.”

The big picture: That prediction is dismissed as fantasy by some experts. But Musk said he can envision a flight as soon as seven years from now, with a ticket price of “around a couple hundred thousand dollars.”
