When I circled the moon and looked back at Earth, my outlook on life and my viewpoint of Earth changed... Earth is a spaceship, just like Apollo - and just like Apollo, the crew must learn to live and work together. We must learn to manage the resources of this world with new imagination.

I didnt go into the NASA program to pick up rocks or to go the moon or anything else. I went in there because I was a military officer, and that was the next notch in my profession.

The Moon is essentially gray - no color - looks like plaster of paris - soft of gray sand.

Well, Frank, my thoughts are very similar. The vast loneliness up here at the moon is awe-inspiring, and it makes you realize what you have back there on earth. The earth from here is a grand oasis in the big vastness of space.

Houston, we've had a problem here.

I was born a year after Lindbergh made his historic trip across the Atlantic. Boys like either dinosaurs or airplanes. I was very much an airplane boy.

The lunar flights give you a correct perception of our existence. You look back at Earth from the moon, and you can put your thumb up to the window and hide the Earth behind your thumb. Everything youve ever known is behind your thumb, and that blue-and-white ball is orbiting a rather normal star, tucked away on the outer edge of a galaxy.
