You could not legally put a human and fly them into space. In fact, you couldn't bring a spaceship back. All those spaceships we were sending commercially into space were one way. You sort of like, got rid of them. And most passengers, who go up, do want to come back down.

Many have built their careers buttressing the status quo, reinforcing what theyve already accomplished, and resisting the radical thinking that can topple their legacy - not exactly the attitude you want when trying to drive innovation forward.

I have the general philosophy of creating the future you want to see.

The folks who go after grand challenges are impatient. They're pissed off. They're sick and tired, but in a passionate way. They're driven by a fire in their bellies to make a difference.

I believed that once we got to the Moon, there was no stopping us. But in fact, we did stop.

I'm extraordinarily passionate about the idea of asteroid mining in the future. Asteroids out there, we know them from those that have fallen on the Earth, there is a class of asteroids, sub-class of nickel/iron asteroids, which are 50,000 times more enriched than Platinum mines on earth.

We are not going to stop here on planet Earth. We're going to move out to other planetary bodies.
