Neil Degrasse Tyson criticizes Elon's plan to go to Mars: Maher: "Can Elon Musk realistically send humans to Mars?" NDT: "I have strong views on that: For him just say 'Let's go to Mars because it's the next thing to do.' What does that venture capitalist meeting look like?: Elon what do you want to do? 'Go to Mars' How much will it cost? '1 trillion dollars' What's the return on investment? 'Nothing' That's a 5 minute meeting." Thank you guy who plays scientist on TV.
