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.

Every couple of years, we could dispatch people from Earth to Mars.

The best way to study Mars is with two hands, eyes and ears of a geologist, first at a moon orbiting Mars… and then on the surface.

Who put their foot in the Missouri River first: Lewis or Clark? Who cares!

I don’t watch ‘American Idol,’ but I wouldn’t call it ‘undignified.’

We could have human intelligence in orbit around Mars, building things there.

Trips to Mars, the Moon, even orbit, will require that we provide astrotourists with as many comforts from home as possible, including paying each other.

Globalisation means many other countries are asserting themselves and trying to take over leadership. Please don’t ask Americans to let others assume the leadership of human exploration. We can do wonderful science on the Moon,...

Going back to the moon is not visionary in restoring space leadership for America. Like its Apollo predecessor, it will prove to be a dead end littered with broken spacecraft, broken dreams and broken policies.

I grew up in New Jersey and never went up the Statue of Liberty.

I am excited to think that the development of commercial capabilities to send humans into low Earth orbit will likely result in so many more Earthlings being able to experience the transformative power of space...

I’m sure that there are places in the deserts in Australia that could be similar to where we might want to go on Mars.

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.

I didn’t start skiing until I was 50. My wife Lois taught me how to ski. I’m proficiently conservative.

I have no intention of selling any more of the historical Apollo 11 items in my possession for the remainder of my life. I intend to pass a portion of these items on to my...

Some things just can’t be described. And stepping onto the moon was one of them.

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...

Russia perhaps is still entertaining the possibility that the moons of Mars might have access to ice or water.

Mars has been flown by, orbited, smacked into, radar inspected, and rocketed onto, as well as bounced upon, rolled over, shoveled, drilled into, baked, and even laser blasted.

Maybe it was the challenge of flight, the opportunity to fly, the competition of summer camp and the inspiration and discipline of West Point. I think all of those things helped me to develop a...

Everyone should take their hats off to Neil Armstrong. He is a humble guy who doesn’t wave his own flag.

America can take man to the moon, and America can take men to Mars – and beyond.

With his deeds, not only words, President Obama has revitalized our struggling space program.

I failed music when I was a teenager.

When President Kennedy took office, I was in the midst of my education.

Us reaching the moon convinced Gorbachev and other leaders that the Soviet Union couldn’t compete with the U.S., so they revised their agenda. But people have short memories.

The first footfalls on Mars will mark a historic milestone, an enterprise that requires human tenacity matched with technology to anchor ourselves on another world.

I came to dedicate my life to opening space to the average person and crafting designs for new spaceships that could take us far from home. But since Apollo ended, such travels were only in...

I understand that Detroit was a pretty rough place to grow up in the ’70s and ’80s.

I really hate to be put in the position of trying to justify something, a decision that was made. I’m a military guy: when a decision is made, I go along with it, whatever the...

If you want poets in space, you’ll have to wait.

Can you imagine, in 2030, taking a space cruise on the very ship that carried the first human beings to Mars? I can’t believe that people wouldn’t line up for that possibility.

Monumental achievements by humanity should be done by major organizations as much together as possible.

I was the first Navy, Marine or Air Force person who had been an astronaut to return back to the Air Force. I had certain expectations about what would be a reasonable and desirable position...

Space architectures capable of supporting a permanent human presence on Mars are extraordinarily complex, with many different interdependent systems.

A mind concerned about danger is a clouded mind. It’s paralyzing.

Save the taxpayer’s money by canceling the Ares 1 and V.

Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth?...
