History will remember the twentieth century for two technological developments: atomic energy and space flight.

Society’s future will depend on a continuous improvement program for the human character. And what will that future bring? I do not know, but it will be exciting.

I suspect that even though the various questions are difficult and many, they are not as difficult and many as those we faced when we started the Apollo [space program] in 1961.

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.

I guess we all like to be recognized not for one piece of fireworks but for the ledger of our daily work.

Good luck, Mr. Gorsky!
