To me, we have never really exploited our ability in low-Earth orbit.

I spent 23 years in the military. I think I'm in a good position to make those judgments on what is necessary in the military and what is not necessary, without buying a lot of things that would not really add to our security.

You can't relive your life.

The Discovery was the most intricate, complex machine man has ever built. It's a testament to our time.

I was hooked on aviation, made model airplanes, and never thought I would be able to fly myself. It cost too much. But then World War II came along and changed all that.

For all the advances in medicine there is still no cure for the common birthday.

I was sold on flying as soon as I had a taste for it.

Fear connotes something that interferes with what you're doing.

As I hurtled through space, one thought kept crossing my mind: Every part of this rocket was supplied by the lowest bidder.

The moment of twilight is simply beautiful.

It has been my observation that the happiest of people, the vibrant doers of the world, are almost always those who are using - who are putting into play, calling upon, depending upon-the greatest number of their God-given talents and capabilities.

An end of something means the beginning of something else, and I don't think that something else is going to be the death of the manned space program.

Too many people, when they get old, think that they have to live by the calendar.

Quite often, while I'm getting up in the morning, I think my warranty is running out on these body parts because it's not working quite the way it used to.

The most important thing we can do is inspire young minds and to advance the kind of science, math and technology education that will help youngsters take us to the next phase of space travel.

I don't know what you could say about a day in which you have seen four beautiful sunsets.

Exploration of course is going to new places but I dont think we go to new places just solely to say well weve been there and come back interesting though it may be. To me each time we go farther into space we should use that to do basic research basic research that cant be done before you go there.

Too many people when they get old think that they have to live by the calendar.

There is still no cure for the common birthday.

I say let's not gamble with American jobs and America's future.

The space station is the most unique laboratory we've ever built. The reason we have it is to do research on materials, people, medical matters, pharmaceuticals - the possibilities are nearly endless.

You can always say that it was scarce dollars when Lewis and Clark wanted to go to the West Coast and explore the West. And people complained about it, I understand, from a reading of the history books.

When the new becomes commonplace, people become accustomed to it. That's a tribute to our sense of adventure.

One of the first things I learned in the Marine Corps is that any military mission has to be defined as precisely as you can possibly define it, and then you size the force and equipment force to accomplish that mission without fail.

As far as trying to analyze all the attention I received, I will leave that to others.

We're not up there in space just to joyride around. We're up there to do things that are of value to everybody right here on Earth.

This is a day we have managed to avoid for a quarter of a century.

We had 83 different space research projects on my last space flight in '98, and they covered the whole gamut.

I've seen John Wayne's 'True Grit' about 10 times.

I pray every day and think everybody should.

Any administration foolish enough to call ketchup a vegetable cannot be expected to cut the mustard.

I'm not interested in my legacy. I made up a word: 'live-acy.' I'm more interested in living.
