I want to make rockets 100 times, if not 1,000 times better. The ultimate objective is to make humanity a multiplanet species. Thirty years from now, there'll be a base on the moon and on Mars, and people will be going back and forth on SpaceX rockets.

What most people know but don't realize they know is that the world is almost entirely solar-powered already. If the sun wasn't there, we'd be a frozen ice ball at three degrees Kelvin, and the sun powers the entire system of precipitation. The whole ecosystem is solar-powered.

I’m nauseatingly pro-American. I would have come here from any country. The U.S. is where great things are possible.

I'm reasonably optimistic about the future, especially the future of the United States - for the century, at least.

When something is important enough, you do it even if the odds are not in your favor.

The extension of life beyond Earth is the most important thing we can do as a species.

America is the spirit of human exploration distilled.
