I didn't go into the NASA program to pick up rocks or to go the moon or anything else. I went in there because I was a military officer, and that was the next notch in my profession.

I grew up in Montpelier, Indiana. It's a little town in the northeast corner of Indiana. It's a rural community; about two thousand people, a very much hometown U.S.A. kind of thing.

I was selected to be an astronaut on a military program called the Manned Orbiting Laboratory back in '67 and that program got cancelled in '69 and NASA ended up taking half of us...

During our journey, we did weight lifting, squats, and dead lifts to regenerate the bone density. Luckily, my muscle mass and bone density did not alter. Our workout was so rigorous.

I think we need to move to the moons of Mars and learn how to control robots that are on the surface. It's not the impatient way of getting there, but Mars has been there a long time.

The Soyuz craft weighs tons, and you're lying on the floor of it on your back. But the Russians do tell you, remember, before you land, stop talking so you don't bite your tongue off.

After the urine is collected over a couple of days, it's dumped into space, which is beautiful to watch because the urine freezes into a glitter of ice crystals shimmering in the sun.

Square astronaut, round hole. But somehow, I'd managed to push myself through it, and here was the truly amazing part: along the way, I'd become a good fit. It had only taken 21 years.

My father was an airline pilot, so we travelled more spontaneously than a lot of families. On a Thursday, we could decide to go somewhere like Barbados the next day for a long weekend.

What everyone in the astronaut corps shares in common is not gender or ethnic background, but motivation, perseverance, and desire - the desire to participate in a voyage of discovery.

Retain the vision for space exploration. If we turn our backs on the vision again, we're going to have to live in a secondary position in human space flight for the rest of the century.

By venturing into space, we improve life for everyone here on Earth - scientific advances and innovations that come from this kind of research create products we use in our daily lives.

These robotic arms, provided by Canada, have been invaluable in allowing us to build, maintain, and repair space structures, and I've been very fortunate to have gotten to operate them.

Every day, in the USA, our radar instruments capture objects of form and composition unknown to us. And there are thousands of witness reports and a quantity of documents to prove this.

The real pleasure was having the chance to enjoy being weightless, and the other was to... spend some time looking out at this beautiful spaceship Earth that we're all lucky to inhabit.

The society of life on Mars, or the challenge of making Mars more livable, will have significant benefits on our attempts to modify and change in some ways the environment here on Earth.

I was motivated to improve the U.S. strategy of going back to the moon in 1985. That's a long time ago. Going back to the moon would be a great achievement for tourism adventure flights.

What's aero braking? That's a way to use the gravity and upper atmosphere of Earth to sling shot a ship out either deeper into space, or slow it down to be 'captured' by Earth's gravity.

Russians aren't perfect. Their politics are messed up, and they keep going through self-defeating economic cycles. But I have a lot of respect for Russia, and a lot of love for Russians.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.

I did have an occasion in 1951 to have two days of observation of many flights of them, they were of different sizes, flying in fighter formation, generally from east to west over Europe.

I was stationed at the flight test center at Wright-Patterson, and I was flying a wide range of airplanes and giving them a lot of different tests. It was a job that I thoroughly enjoyed.

After assembly complete, when we have a larger crew on orbit, a more complex vehicle, more laboratories and more robot arms, maybe we'll have room for specialists. But right now we don't.

The feeling of reduced gravity and the limitations of the space suit resulted in a slow-motion movement. Perhaps not too far from a trampoline, but without the springiness and instability.

My expertise is the space program and what it should be in the future based on my experience of looking at the transitions that we've made between pre-Sputnik days and getting to the moon.

When you look out the window of a spaceship, you see entire countries, vast swaths of continents. One turn of the head covers what once took thousands of years to traverse at ground level.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet, and our visions go rather further than that, and our opportunities are unlimited.

When you have an asteroid threatening Earth, it's uncertain where it's going to hit until the last minute; the decision to take action has to be coordinated by the international community.

When we get there, if we don't find any life on Mars, from that point on there will be life on Mars because we'll bring it there, whether it's germs and leftover urine bags, whatever it is.

To be on my very first spacewalk, to be outside, and to have contamination in my suit to the point that I couldn't see in either eye - that, I think, would cause some people to lose control.

The Next Generation Space Telescope, which will be located much further away from the Earth than the Hubble Space Telescope presently is, will also explore the infrared part of the spectrum.

Although as a boy I had dreamed about going into space, I had completely forgotten about that until one day I received a call from an astronaut, who suggested that I should join the program.

I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets, which obviously are a little more technically advanced than we are here on earth.

If we die, we want people to accept it. We're in a risky business, and we hope that if anything happens to us, it will not delay the program. The conquest of space is worth the risk of life.

My view is that we should go back to the moon, build up the infrastructure to make flights there commonplace - be comfortable with it - then use that infrastructure to expand and go to Mars.

I am starting to think about those things that I miss from home. Ice cream is definitely one of those things we do not have up here. My favorite is pistachio. I love it with chocolate sauce.

Anything we can do in the near future that begins to stimulate the interest of people - seeing somebody down the street have an opportunity to go into space - buoys up the whole neighborhood.

Almost everything worthwhile carries with it some sort of risk, whether it's starting a new business, whether it's leaving home, whether it's getting married, or whether it's flying in space.

And, that's what I truly believe that we're doing when we're advancing scientific knowledge is we're someday making the world better. Not only for our children, but for all people after that.

If we die, we want people to accept it. We are in a risky business, and we hope that if anything happens to us, it will not delay the program. The conquest of space is worth the risk of life.

There are just hundreds of people that have inspired and influenced me in a number of different ways. First of all, you can't forget your parents and all they've done to help you to get here.

I would say the most help I got was from my dad. My dad is a civil engineer in Switzerland; he's 90 years old now, so he's no longer active as a civil engineer, but still a very active person.

That's what we want to do here at Johnson Space Center. I think what we have always brought to NASA and brought to the country is trying to push the boundaries, trying to go to the next level.

Lindsay Lohan isn't a DJ, but because of her celebrity power she can do a gig somewhere, put her name on a flyer, and she'll probably bring in more people and make more money than I ever will.

When we look down at the Earth from space we see this amazing, indescribably beautiful planet; it looks like a living, breathing organism. But it also, at the same time, looks extremely fragile

I think I am a smart aleck because I grew up close enough to Boston, and most people from Massachusetts talk fast, and I have a little bit of a wiseacre, and I think I'm a little bit like that.

Planets look about the same here as they do to you on the Earth because we really aren't that much closer. Our home, the International Space Station, orbits around the Earth at about 200 miles.

But, what we need to get out of the first EVA is to have the arm completely unfolded and powered so that they can keep the temperature under control. That will really the call of the first EVA.

Astronauts working for the government will always need to be either pilots or mission specialists. Those who want to be pilots should have military experience - ideally, a test pilot background.

I was sent to Korea, which was excellent training for what came later. I was assigned to remain on duty until I completed one hundred combat missions - or got knocked out - whichever came first.
