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.Collection: Space
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; now it's time for us to live and work on Mars, first on its moons and then on its surface.Collection: Work
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 lift our eyes up and look into the skies and move forward in an evolutionary way.Collection: Future
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 will reduce the amount of motivation it provides to young people.Collection: Sad
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. I could see our shining blue planet Earth poised in the darkness of space.Collection: Space
Look at what Silicon Valley has done - the advance of computers.Collection: Computers
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.Collection: Science
I think humans will reach Mars, and I would like to see it happen in my lifetime.Collection: Space
We must still think of ourselves as pioneers to understand the importance of space.Collection: Space
I think the American Dream used to be achieving one's goals in your field of choice - and from that, all other things would follow. Now, I think the dream has morphed into the pursuit of money: Accumulate enough of it, and the rest will follow.Collection: Money
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 cooperation up above the atmosphere that's needed to help each other.Collection: Space
Space travel for everyone is the next frontier in the human experience.Collection: Space
Space tourism is a logical outgrowth of the adventure tourist market.Collection: Space
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.Collection: Space
The way I see it, what is going to come out of the moon activities is a respect for U.S. leadership.Collection: Leadership
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.Collection: Leadership
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 way to understand how those things work.Collection: Computers
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 study and get involved in. And then I got into the space program, and how disciplined can you get?Collection: Space
The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.Collection: Space
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.Collection: Life
There were about six years when there was not one American who went into space. We shouldn't do that again.Collection: Space
Absolutely the United States should lead in space, for the survival of the United States. It's inspiring for the next generation. If we lose leadership, then we'll be using Chinese capability to inspire Americans.Collection: Leadership
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.Collection: Technology
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, and wonderful commercial things. Then we can pack up and move on to Mars.Collection: Leadership
If we can conquer space, we can conquer childhood hunger.Collection: Space
The biggest benefit of Apollo was the inspiration it gave to a growing generation to get into science and aerospace.Collection: Science
You can tell I'm not too bashful about some of my feelings.
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 life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.
In space, you don't get that much noise. Noise doesn't propagate in a vacuum.
We need the next generation to be motivated and to push technological boundaries, to seek out new innovations.
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.
Unfortunately, kids are led to believe things are easier to achieve than they really are.
As a student, I wrote English reports on science fiction.
A family needs to work as a team, supporting each other's individual aims and aspirations.
Everyone who's been in space would, I'm sure, welcome the opportunity for a return to the exhilarating experiences there.
Russia perhaps is still entertaining the possibility that the moons of Mars might have access to ice or water.
I am not sure about Bill Nelson. I haven't heard him say, 'Let's junk the NASA plan to send humans to the moon.' He's not about to say that. That would not be very popular.
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.
Growing up, I was fascinated with Buck Rogers' airplanes. As I began to mature in World War II, it became jets and rocket planes. But it was always in the air.
I do celebrity ski races all over the world.
The way I see it, commercial interests should manage a lunar base while NASA gets on with the really important task of flying to Mars.
Like actors and writers who are on and off again in terms of employment, I had a very unstructured life.
Astronauts are not superhuman. They lead ordinary lives and have varied personalities.
Pascal Lee is a true pioneer of Mars exploration.
It's time to open the space frontier to citizen explorers.
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 children and to loan the most important items for permanent display in suitable museums around the country.
If you want poets in space, you'll have to wait.
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.
