Flight out of the atmosphere is a simple thing to do and should have been available to the public twenty years ago. Ten years from now, we will have space tourism where you will be able to see the black sky and the curvature of the earth. It will be the most exciting roller coaster ride you can buy.

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.

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

Look at the aerospace industry as it was just after the Kennedy talk. We were hiring like crazy. We were trying to get people graduated from college. Hey, you got to go to the program. We need you.

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

A NASA-funded study estimates that if the price of a ticket to space approached $100,000, close to a million people would buy one. That's a $100 billion industry. Microsoft cofounder Paul Allen gave me $20 million in startup funding to go after that market.

I have a hunch the most important reason we're going to space is not known now.
