We've explored every type of environment in the solar system at least once.
With 'Apollo 13,' I wasn't sure the genre would work, because space films hadn't done that well.
When I did my spacewalks, it was during space station construction. So the shuttle was docked to the fledgling ISS at the time. So we would always stay tethered.
I would love to set foot on another planet - lunar or Mars or somewhere.
I remember in 1967, when there was that terrible fire on NASA's Apollo 1 rocket that killed three astronauts, my father made pure oxygen and we lit this tiny cup and burned it. Suddenly, we had an unbelievable jet and a fire. You just could see exactly what had happened.
Then during the mission itself, I used the space shuttle's robot arm to release a satellite into orbit.
Man will not always stay on Earth; the pursuit of light and space will lead him to penetrate the bounds of the atmosphere, timidly at first, but in the end to conquer the whole of solar space.
NASA has now sent probes to every planet and dwarf planet. It took less than a century.
It's important to bring things back from the Space Station because, unlike somebody living at the house where the garbage truck comes by twice a week, they don't have that in space.
The American people want and deserve a space program truly worthy of a nation of pioneers.
We've been surrounded by images of space our whole lives, from the speculative images of science fiction to the inspirational visions of artists to the increasingly beautiful pictures made possible by complex technologies. But whilst we have an overwhelmingly vivid visual understanding of space, we have no sense of what space sounds like.
I have a little piece of Hubble that someone brought back from one of the repair missions. It's on my desk, where I work. I do feel a personal connection to it. It's been part of my life for 20 years.
The fastest manned vehicle in history was Apollo 10. It reached 25,000 mph.
I've always been a fan of space exploration, and I filled our entire office with space artifacts.
The thought of being in space, and kind of enclosed, I find would be very claustrophobic. I think I would panic in that situation.
When Kennedy said, 'Let's go to the moon,' we didn't yet have a vehicle that wouldn't kill you on launch. He said we'll land a man on the moon in eight years and bring him back. That was an audacious goal to put forth in front of the American people.
I've had a chance to fly a lot of different airplanes, but it was nothing like the shuttle ride.
It is rash to set limits to the progress of science. A man who had maintained at Queen Victoria’s Jubilee that within fifty years one would fly the Atlantic in a matter of hours would have risked being certified and locked up; yet we have seen this happen, and in the circumstances I am not prepared to rule out with any confidence the possibility one day of journeys through space in vessels carrying supplies of food and oxygen to the moon and the nearer planets.
By the time I finished high school, I knew I wanted to become an astronomer. By the time I finished college, I knew I wanted to be part of the American space program. And that's exactly what I did.
Having walked on the Moon, I know something about what we need to explore, really explore, in space.
When I was a child, and I was at our school, everybody's parents were involved in space program. In every class, we have several kids whose fathers were flown cosmonauts or who prepared for the flight.
I've been approached to do some things with astronauts and the preparation that astronauts go through.
As far as the satellite itself is concerned, that doesn’t give me any apprehension at all.
I would say keep supporting space flight, keep telling the public and the politicians why it's important to advance science and explore the galaxy. I encourage the Japanese to keep doing what they're doing.
The best space movie in my view is 'Apollo 13.' That's just the way it happened.
We don't have parades for mathematicians, we have parades for astronauts. You don't think about all the thousands of people who worked on that capsule and crunched the numbers and were integral in getting that into space.
