"I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul ... we're required to do these things just as salmon swim upstream."

"Friends and colleagues all of a sudden looked at us, treated us, slightly differently than had months or years before when we were working together. I never quite understood that."

"It's an interesting place to be. I recommend it."

"The horizon seems quite close to you because the curvature is so much more pronounced than here on Earth."

"It's a brilliant surface in that sunlight."

"I thought, well. when I step off it's just going to be a little step — a step from there down to there — but then I thought about all those 400,000 people who had given me the opportunity to make that step and thought it's going to be a big something for all those folks and, indeed for a lot of others that weren't even involved in the project, so it was kind of a simple correlation."

"Our autopilot was taking us into a very large crater, about the size of a big football stadium with steep slopes on the crater covered with very large rocks about the size of automobiles that was not the kind of place that I wanted to try to make the first landing."

"I'll not assert that it was a diversion which prevented a war, but nevertheless, it was a diversion."

"Thank you, Mr. Chairman. I am in the position of a pilot without his checklist, so I'll have to wing it a bit. ... [Prior to the Apollo missions,] no one knew what kind of person could be persuaded to take the trip. Prisoners were suggested. Soldiers could be ordered. Photographers could take pictures — and they're expendable. Doctors understood the limits of human physiology. Finally, both sides picked pilots."

"A century hence, 2000 may be viewed as quite a primitive period in human history. It's something to hope for. ... I am, and ever will be, a white-socks, pocket-protector, nerdy engineer — born under the second law of thermodynamics, steeped in the steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow. As an engineer, I take a substantial amount of pride in the accomplishments of my profession."

"Pilots take no special joy in walking: pilots like flying. Pilots generally take pride in a good landing, not in getting out of the vehicle."

"Space has not changed but technology has, in many cases, improved dramatically. A good example is digital technology where today's cell phones are far more powerful than the computers on the Apollo Command Module and Lunar Module that we used to navigate to the moon and operate all the spacecraft control systems."

"The exciting part for me, as a pilot, was the landing on the moon. That was the time that we had achieved the national goal of putting Americans on the moon. The landing approach was, by far, the most difficult and challenging part of the flight. Walking on the lunar surface was very interesting, but it was something we looked on as reasonably safe and predictable. So the feeling of elation accompanied the landing rather than the walking."

"I am comfortable with my level of public discourse."

"I remember on the trip home on Apollo 11 it suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small."

"Through books you will meet poets and novelists whose creations will fire your imagination. You will meet the great thinkers who will share with you their philosophies, their concepts of the world, of humanity and of creation. You will learn about events that have shaped our history, of deeds both noble and ignoble. All of this knowledge is yours for the taking... Your library is a storehouse for mind and spirit. Use it well."

"I'm quite certain that we'll have such [lunar] bases in our lifetime, somewhat like the Antarctic stations and similar scientific outposts, continually manned."

"Houston, Tranquility Base here. The Eagle has landed."

"That's one small step for [a] man, one giant leap for mankind."

"At few other moments has one person become the fulcrum of such weighty imperatives — to win a famous victory for America and vindicate a vast investment of national treasure, to penetrate a hostile frontier, to master a new technology, to navigate a harrowing descent to the unknown — all in the glare of rapt global attention. By the time he landed in the Sea of Tranquility, the country boy from Ohio had already spent most of his adult life in jobs where intensity of focus and the threat of violent death were part of his daily routine. He was used to all of that. It was, instead, the loss of privacy that appalled him. He loved to fly, and he loved his country, and in the name of those passions he was willing to risk not only his hide but a piece of his soul. Only a piece, however — a mere finger's worth — and no more. ... Those who know him say he is a smart and intensely private, even shy, man determined to live life on his own terms despite having floated down that ladder into the public domain. Whether as an astronaut, naval combat aviator, test pilot, civil servant, engineer, absent-minded professor, gentleman farmer, businessman, civic booster, amateur musician, husband or father, Neil Armstrong has followed his own code."

"Among the greatest of American heroes — not just of his time, but of all time."

"Better if he had said something natural like, "Jesus, here we are.""

"Many short-sighted fools think that going to the Moon was just a stunt. But the astronauts knew the meaning of what they were doing, as is shown by Neil Armstrong's first words in stepping down onto the soil of Luna: "One small step for a man, one giant leap for mankind.""

"Some years ago, I was lucky enough invited to a gathering of great and good people: artists and scientists, writers and discoverers of things. And I felt that at any moment they would realise that I didn't qualify to be there, among these people who had really done things. On my second or third night there, I was standing at the back of the hall, while a musical entertainment happened, and I started talking to a very nice, polite, elderly gentleman about several things, including our shared first name. And then he pointed to the hall of people, and said words to the effect of, "I just look at all these people, and I think, what the heck am I doing here? They’ve made amazing things. I just went where I was sent." And I said, "Yes. But you were the first man on the moon. I think that counts for something." And I felt a bit better. Because if Neil Armstrong felt like an imposter, maybe everyone did."
