It's a fixer-upper of a planet but we could make it work.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

In order for us to have a future that's exciting and inspiring, it has to be one where we're a space-bearing civilization.

When I was in college, I wanted to be involved in things that would change the world.

I always invest my own money in the companies that I create. I don't believe in the whole thing of just using other people's money. I don't think that's right. I'm not going to ask other people to invest in something if I'm not prepared to do so myself.

It is definitely true that the fundamental enabling technology for electric cars is lithium-ion as a cell chemistry technology. In the absence of that, I don't think it's possible to make an electric car that is competitive with a gasoline car.

It was obvious to me that we could never colonize Mars without reusability, any more than America would have been colonized if they had to burn the ships after every trip.
