We'll go back to the moon by not learning anything new.

I was shocked to find that there were actually climate scientists who wouldn't share the raw data, but would only share their conclusions in summary graphs that were used to prove their various theories about planet warming. In fact I began to smell something really bad, and the worse that smell got, the deeper I looked.

NASA's myriad failures are in many ways the natural consequence of a catastrophic combination of bureaucracy, monopoly, and a calcifying aversion to the kind of risk necessary for innovation.

In 12 or 15 years, there will be routine, affordable space tourism not just in the U.S. but in a lot of countries.

Achieving something that has never existed in manned spaceflight and that is high volume and public access.

The next 15 years will see thousands of people leave the atmosphere on suborbital flights. My company's SS2 system might fly 100,000 people by 2024. If it is shown to be highly profitable, perhaps we will see 20,000 people traveling to orbit by 2035, and then thousands to the moon by 2050. If we make a courageous decision, like the program we kicked off for Apollo, we will see our grandchildren in outposts on other planets.

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.
