I have been in relatively high-risk businesses all of my adult life. Few of the others, however, had the possibility of direct gains in knowledge which this one had. I have confidence in the equipment, the planning, the training. I suspect that on a risk-gain ratio, this project would compare very, very favorably with those to which I've been accustomed on the past 20 years.

As I stepped on the moon, I looked around, dazed...magnifice nt. The vast, sandy silver surface was almost illusory.

How we use the knowledge we gain determines our progress on earth, in space or on the moon. Your library is a storehouse for mind and spirit. Use it well.

I'm substantially concerned about the policy directions of the space agency. We have a situation in the U.S. where the White House and Congress are at odds over what the future direction should be. They're sort of playing a game and NASA is the shuttlecock that they're hitting back and forth.

We have no proof, But if we extrapolate, based on the best information we have available to us, we have to come to the conclusion that ... other life probably exists out there and perhaps in many places.

Figure out how to build a brand and stick by it so people know what to expect.

There are people I'll always love to listen to, and I'm always ending up discovering new songs by them, which is crazy. Like Stevie Wonder.
