Hal gave me a lot of breaks and honored me with space and freedom. He pulled no punches and wore his heart on his sleeve. I loved the man.

Beyond a critical point within a finite space, freedom diminishes as numbers increase. . . . the human question is not how many can possibly survive within the system, but what kind of existence is possible for those who do survive.

The moment that judgement stops through acceptance of what it is, you are free of the mind. You have made room for love, for joy, for peace.

Our nation recommitted itself to making manned space flight as safe as possible after the Challenger explosion. But these efforts have lagged amid the budget pressures and cuts of recent years. Now, in the wake of this new tragedy, we need to make a new commitment. And we must live up to it.

I think the biggest issue for NASA and for the Russian Space Agency and other folks... (is) everybody has to accept some cultural change to make this happen. It's probably the biggest problem in front of us and it's probably one of the hardest things we have got to go work on.

I think some of (the developments) would be quite nice if there was some space around them. It's almost as if they're shouting at each other.
