Neil deGrasse Tyson Says Humans Won't Reach Mars: 'Zero' Probability in Our Lifetime
Diary of a CEO
Most Replayed Moment: Neil deGrasse Tyson On The Future Of Humanity! Will We Ever Go To Mars?
"You wanna know why? Yeah, it's just zero... We only do big expensive things if there's a geopolitical reason for it, either an economic reason or a defense reason, not just because it's the next thing to do."
Astrophysicist Neil deGrasse Tyson argues that despite SpaceX's ambitions, humans won't reach Mars in our lifetime because there's no geopolitical or economic motivation. He points out that the moon landing only happened to beat the Soviets, and we stopped going once we won that race. With Mars being a mile away on a scale model versus the moon's 30 feet, and costing an estimated $1 trillion, he sees no business case for the journey.
