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....

It was interesting to think that the very first liquid ever poured on the Moon, and the first food eaten there, were communion elements.

I think both the space shuttle program and the International Space Station program have not really lived up to their expectations.

To me, money is a commodity that a person must have to function, not a goal in itself.

I don’t go through life verbalizing what I feel.

To move forward, what’s required is a unified space agenda based on exploration, science, development, commerce, and security.

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.

The biggest benefit of Apollo was the inspiration it gave to a growing generation to get into science and aerospace.

All the Chinese have to do is fly around the Moon and back, and they’ll appear to have won the return to the Moon with humans. They could put one person on the surface of...

I am Buzz Lightyear!

Computers allow us to squeeze the most out of everything, whether it’s Google looking up things, so I guess that tends to make us a little lazy about reading books and doing things the hard...

I want to reach a new generation. That’s why I am Twittering now. I have a BlackBerry, an iPhone and a Mac.

Before deciding what to do about national space policy, Obama set up an outside review panel of space experts, headed up by my friend Norm Augustine, former head of Lockheed Martin and a former government...

It’s real easy to manufacture what you think the people want to hear. But that’s not very honest.

The pilgrims on the Mayflower landed at Plymouth Rock. To my knowledge, they didn’t wait around for a return trip to Europe. You settle some place with a purpose. If you don’t want to do...

Ray Bradbury is one who is contributing to the understanding of the imagination and the curiosity of the human race.

We should’ve asked China to be a portion of the space station. We should’ve worked out ways that we can… just give away the technology that we have that puts things up into space, with...

Not everyone will understand this need for America to lead the world in space.

I’m urging NASA to foster the development of what I call ‘runway landers.’ No, that’s not the name of a high stakes gambler from Vegas. It’s a type of spacecraft that flies to orbit like...

By refocusing our space program on Mars for America’s future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race;...

A family needs to work as a team, supporting each other’s individual aims and aspirations.

I’m in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.

We need the next generation to be motivated and to push technological boundaries, to seek out new innovations.

I don’t think we’re going to build a 50-person spacecraft or a 100-person spacecraft.

Unfortunately, kids are led to believe things are easier to achieve than they really are.

There are many people talking about access to space and, ‘How can we make that cheaper? How can we turn that into a Southwest Airlines versus the big airlines?’

We can continue to try and clean up the gutters all over the world and spend all of our resources looking at just the dirty spots and trying to make them clean. Or we can...

Armstrong described the lunar surface as ‘beautiful.’ I thought to myself, ‘It’s not really beautiful. It’s magnificent that we’re here, but what a desolate place we are visiting.’

I feel we need to remind the world about the Apollo missions and that we can still do impossible things.

Do we really need these big, gigantic, heavy rockets? What if we launch a rocket that’s empty, and its sole purpose is to act as a source of fuel on the Moon? Who should build...

I’m not in favor of just taking short-term isolated situations and depleting our resources to keep our climate just the way it is today.

Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, and an asteroid is a good stopping point, then fine. But now it’s turned...

Timing has always been a key element in my life. I have been blessed to have been in the right place at the right time.

What are you going to do with astronauts who first reach the surface of Mars and then turn around and rocket back home-ward? What are they going to do, write their memoirs? Would they go...

Sending a couple of guys to the Moon and bringing them back safely? That’s a stunt! That’s not historic.

When I was a little kid, we only knew about our nine planets. Since then, we’ve downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.

One of the major problems with long-term deep space human flight is the requirement for radiation shielding.

Landing in the ocean and waiting for the Navy to come alongside and haul you out of the drink is what space capsules require. And after the capsule is recovered, it would take weeks for...

My favourite thing to do on this planet is to scuba dive.
