I still say, ‘Shoot for the moon; you might get there.’

The beauty of Hawaii probably surpasses other places. I like the Big Island and the two mountains, Mauna Loa and Mauna Kea, where you can look out at the stars.

Extraordinary observations require extraordinary evidence.

As someone who flew two space capsules and twice landed in the ocean, I can attest from personal experience how much logistics work is needed to get you home.

I shot down two airplanes in Korea, so I wasn’t a slouch.

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.

Ir à lua e voltar não é tão desafiador quanto retornar à terra e ter de lidar com a humanidade.

There’s a need for accepting responsibility – for a person’s life and making choices that are not just ones for immediate short-term comfort. You need to make an investment, and the investment is in health...

I’ve led a life of such structured discipline and always had a goal in mind of knowing what I was doing, from West Point to the Air Force combat, MIT, looking for new things to...

My Sunday mornings are spent in a recovery meeting in Pacific Palisades.

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.

Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.

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...

I know: If you’re looking down at Earth, you’re looking through an atmosphere that has a bit of haze in many places and not just occasional clouds.

The guys who walk on Mars are going to be historic.

There are always door openings. And gradually, it accumulates. The opportunities open up in front of you.

I am definitely not rich.

There were about six years when there was not one American who went into space. We shouldn’t do that again.

The decision to go to the moon is now appreciated and associated with President Kennedy’s speech, but somebody else had told him it was a good idea. It turned out to be a good commitment,...

There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.

NASA’s been one of the most successful public investments in motivating students to do well and achieve all they can achieve, and it’s sad that we are turning the program in a direction where it...

Having walked on the Moon, I know something about what we need to explore, really explore, in space.

Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.

I think the climate has been changing for billions of years.

As we begin to have landings on the moon, we can alternate those with vertical launch of similar crew modules on similar launch vehicles for vertical-launch tourism in space, if you want to call it...

Mars is far more attractive as an outpost colony for earthlings than the moon is.

Just as Mars – a desert planet – gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth...

Pascal Lee is a true pioneer of Mars exploration.

People come up to me and say, ‘It’s too bad the space program got canceled.’ This is not the case, and yet that is what most of the public thinks has happened.

Most people never believed in the real possibility of going to the moon, and neither did I until I was in my twenties.

I want people to go into space, to orbit around the world a few times, even to stay there for 24 hours and then come back to where they took off. And I also want...

I’ve been to the Titanic in a yellow submarine and the North Pole in a Russian nuclear ice breaker.

The way I see it, what is going to come out of the moon activities is a respect for U.S. leadership.

There should be an international lunar base. That is certainly doable.

I do celebrity ski races all over the world.

There’s no guarantee that the United States will be around 200 years from now.

The moon I see now is the same moon I saw before. Except that before, when I looked at it, it was in anticipation of what it would be like when I got there. That’s...

I think humans will reach Mars, and I would like to see it happen in my lifetime.

To send humans back to the moon would not be advancing. It would be more than 50 years after the first moon landing when we got there, and we’d probably be welcomed by the Chinese....

Heavy lifting doesn’t need to be heavy spending if we do the job right.

Any observations from the Moon or a sense of realising this or that about the greater meaning of things wasn’t as influential for me as the experience of coming back and dealing with being a...

I want to keep on the move, keep stimulated and challenged.

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.

We must still think of ourselves as pioneers to understand the importance of space.

Nobody ever asks who was the seventh person on the Moon. The only thing they know is who’s number one and who’s number two. Does anybody know who the last man was?

People communicate in Twittering ways. I’ve learned how to do that.

Space is not just going up and coming back down again. Space is getting into orbit and being there, living there, establishing a presence, a permanence.

My first inclination is to be a bit skeptical about the claims that human-produced carbon dioxide is the direct contributor to global warming.

I wrote ‘Reaching for the Moon’ because I wanted to tell kids that all of us have a moon, a dream, that we can strive for. Even if you don’t attain it, you can at...

Whenever I gaze up at the moon, I feel like I’m on a time machine. I am back to that precious pinpoint of time, standing on the foreboding – yet beautiful – Sea of Tranquility....
