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, and ever will be, a white-socks, pocket-protector, nerdy engineer, born under the second law of thermodynamics, steeped in steam tables, in love with free-body diagrams, transformed by Laplace and propelled by compressible flow.

I can't hear it. But the 'a' is implied, so I'm happy if they just put it in parentheses. (1982)

I would hope that history would grant me leeway for dropping the syllable and understand that it was certainly intended, even if it was not said — although it might actually have been. (2008)

That's one small step for a man, one giant leap for mankind

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.

For The United States, the leading space faring nation for nearly half a century, to be without carriage to low Earth orbit and with no human exploration capability to go beyond Earth orbit for an indeterminate time into the future, destines our nation to become one of second or even third rate stature. While the President's plan envisages humans traveling away from Earth and perhaps toward Mars at some time in the future, the lack of developed rockets and spacecraft will assure that ability will not be available for many years. Without the skill and experience that actual spacecraft operation provides, the USA is far too likely to be on a long downhill slide to mediocrity. America must decide if it wishes to remain a leader in space. If it does, we should institute a program which will give us the very best chance of achieving that goal.

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.

Research is creating new knowledge.

Good luck, Mr. Gorsky

History is a sequence of random events and unpredictable choices, which is why the future is so difficult to foresee.

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.
