I believe that every human has a finite number of heartbeats. I don't intend to waste any of mine running around doing exercises.
There can be no great accomplishment without risk.
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.
That's one small step for [a] man, one giant leap for mankind.
Houston, Tranquility Base here. The Eagle has landed.
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.
