I've been to the Titanic in a yellow submarine and the North Pole in a Russian nuclear ice breaker.

The honor you have given us goes not to us as a crew, but to ... all Americans, who believed, who persevered with us. What Apollo has begun we hope will spread out in many directions, not just in space, but underneath the seas, and in the cities to tell us unforgettably what we will and must do. There are footprints on the moon. Those footprints belong to each and every one of you, to all mankind. They are there because of the blood, sweat, and tears of millions of people. Those footprints are the symbol of true human spirit.

The surface of the moon is like nothing here on Earth! It's totally lacking any evidence of life. It has lots of fine, talcum-powderlike dust mixed with a complete variety of pebbles, rocks, and boulders. Many pebbles, fewer rocks, and even fewer boulders naturally make up its surface. The dust is a very fine, overall dark gray. And with no air molecules to separate the dust, it clings together like cement.

My expertise is the space program and what it should be in the future based on my experience of looking at the transitions that we've made between pre-Sputnik days and getting to the moon.

Heavy lifting doesn't need to be heavy spending if we do the job right.

Anything we can do in the near future that begins to stimulate the interest of people - seeing somebody down the street have an opportunity to go into space - buoys up the whole neighborhood.

As time goes by, I'm increasingly impressed by how very special and timely it was that we got the degree of national commitment needed to put people on the Moon. For the first time, this nation was united in trying to develop an interplanetary capability. We've been trying to repeat that situation ever since.
