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

It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

If humanity doesn’t land on Mars in my lifetime, I would be very disappointed.

People will visit Mars, they will settle mars, and we should because it’s cool.

You could warm Mars up, over time, with greenhouse gases.

The pace of progress on Mars depends upon the pace of progress of SpaceX.

Land on Mars, a round-trip ticket – half a million dollars. It can be done.

My vision is for a fully reusable rocket transport system between Earth and Mars that is able to re-fuel on Mars – this is very important – so you don’t have to carry the return fuel when you go there.

I know Elon, we’re very like minded in many ways. We’re not conceptual twins. One thing I want us to do is go to Mars, but for me it’s one thing. He’s singularly focused on that. I think motivation wise, for me I don’t find that Plan B idea motivating. I don’t want a plan B for Earth, I want Plan B to make sure Plan A works.

The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It’ll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn’t been reusable.
