I shot down two airplanes in Korea, so I wasn't a slouch.

What comes after the moon? I think you can guess: Mars.

I came to dedicate my life to opening space to the average person and crafting designs for new spaceships that could take us far from home. But since Apollo ended, such travels were only in our collective memory.

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.

I think the American Dream used to be achieving one's goals in your field of choice-and from that all other things would follow. Now, I think the dream has morphed into the pursuit of money: Accumulate enough of it, and the rest will follow. We've become more materialistic. For balance, I think we need to get back to idealism and patriotism, but also be realistic with our monetary goals.

I participated with great honor in becoming one of the first to land on the moon, and now I am devoting and have devoted many years of my life to enabling Americans to lead international nations to permanence on the planet Mars.

There's a historical milestone in the fact that our Apollo 11 landing on the moon took place a mere 66 years after the Wright Brothers' first flight.
