With any luck, by the time NASA's space probe hits Pluto, you'll be booking a spaceflight with a privately run suborbital airline.

When theres ever a breakthrough, a true breakthrough, you can go back and find a time period when the consensus was 'well, thats nonsense!', so what that means is that a true creative researcher has to have confidence in nonsense.

It's not good enough for us to have generations of kids that ... look forward to a better version of a cell phone with a video in it. They need to look forward to exploration.

No one knows how to make going to orbit orders of magnitude safer and orders of magnitude more affordable.

I like to call the difference between research and development. Some people use that interchangeably. They'll say R&D. They're two totally different things.

Our goal is to show that you can develop a robust, safe manned space program and do it at an extremely low cost.

Airplanes were invented by natural selection. Now you can say that intelligent design designs our airplanes of today, but there was no intelligent design really designing those early airplanes. There were probably at least 30,000 different things tried, and when they crash and kill the pilot, don't try that again.
