John Glenn Quotes

The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.

There's a certain romanticism associated with exploration of space, which is one of the major factors why we'll continue.

I think that it's good for us to be able to travel in space and do research in space, and I emphasize the research, because space travel to me is far more than just seeing how far we can go.

Exploration, of course, is going to new places, but I don't think we go to new places just solely to say: "Well, we've been there," and come back, interesting though it may be. To me, each time we go farther into space we should use that to do basic research - basic research that can't be done before you go there.

We should be ready to reach out beyond our planet and beyond our solar system to find out what is really going on out there.

I could have gone on flying through space forever.

There are many in the field of cosmology, who believe as I do, that finding ways to travel great distances will be essential to keeping human kind alive in an aging universe.

Exploration of space is worth it because humans need to explore. Knowledge is always good, and it's a really cool thing to see.

So we say, oh, my goodness; we think we've found another Earth-like planet. We will start trying to figure out how to get there. And I have this strong belief that whatever we think we can do, whatever we can dream, we can do.

Space is the ultimate frontier. I think when people historically thought of the frontier, there was where you were living and then there was some edge beyond which no one had explored.

The best thing about space travel is that it made it possible to go elsewhere.

I can only think of one experience which might exceed in interest a few hours spent under water, and that would be a journey to Mars.

We used to joke about canned men, putting people in a can and seeing how far you can send them and bring them back. That's not the purpose of this program... Space is a laboratory, and we go into it to work and learn the new.

We're not sane enough yet to enter space until we learn to live together in peace on Earth.

I ended up realizing that NASA was unlikely to get me into space, or get me to the moon or beyond, and I needed some other way to drive this.

Traveling through space is stupifyingly monotonous.

I can't think that leaving Earth once is enough.

I'm hoping that the suspension of the space program is just that, a suspension, and that it's not the final say in the matter, because I think we need it.

Mankind flung its advance agents ever outward, ever outward. Eventually it flung them out into space, into the colorless, tasteless, weightless sea of outwardness without end. It flung them like stones.

Ships and sails proper for the heavenly air should be fashioned. Then there will also be people, who do not shrink from the dreary vastness of space.

I think that space flight is a condition of Nature that comes into effect when an intelligent species reaches the saturation point of its planetary habitat combined with a certain level of technological ability... I think it is a built-in gene-directed drive for the spreading of the species and its continuation.

The cool things about space is when you put your pants on here, you can put them on two legs at a time.

I have looked further into space than ever human being did before me. I have observed stars of which the light, it can be proved, must take two million years to reach the earth.

The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space-each discovered, studied, and remembered by the ones who made the irrational decision.

Ever since I saw the moon landing as a young teenager, I was determined I would go into space one day.
