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.

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.

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

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

By 1931, after a few years' experience of flying scheduled airlines, those planes were operating at roughly 600 times the safety of the space shuttle. I look at safety not in terms of fatalities per passenger-mile, but when you get in and close the door, what is the risk of dying on this flight?

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

NASA works for the White House. There are many at NASA that wish they were building a modern replacement for the Shuttle. However, they had marching orders to instead work on other things, some of which should have no place in a research organization.
