It’s time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind.

Once you get into space, you can really unleash a lot of creativity, but the launch itself? I have been through all of the creative ways, and believe me, chemical rockets are the best.

The learned is happy, nature to explore; The fool is happy, that he knows no more.

What interests me in life is curiosity, challenges, the good fight with its victories and defeats.

Going to Southeast Asia for the first time and tasting that spectrum of flavors – that certainly changed my whole palate, the kind of foods I crave. A lot of the dishes I used to love became boring to me.

I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.

Only by going alone in silence, without baggage, can one truly get into the heart of the wilderness. All other travel is mere dust and hotels and baggage and chatter.

The common question that gets asked in business is, ‚why?‘ That’s a good question, but an equally valid question is, ‚why not?‘

Being prime minister is a lonely job… you cannot lead from the crowd.

I think we are at the dawn of a new era in commercial space exploration.

Perhaps the greatest social service that can be rendered by anybody to the country and to mankind is to bring up a family.

Thinking is more interesting than knowing, but less interesting than looking.

Some day science may have the existence of mankind in power, and the human race can commit suicide by blowing up the world.

I’ve experienced great things, I’ve experienced great tragedies. I’ve done almost everything I could possibly ever imagine doing, but I just know that there’s more.

I have survivor’s curiosity, I guess.

Whosoever is delighted in solitude is either a wild beast or a god.

I’m astounded by people who want to ‚know‘ the universe when it’s hard enough to find your way around Chinatown.

We still do not know one thousandth of one percent of what nature has revealed to us.

I think my first thought on reaching the summit- of course, I was very, very pleased to be there, naturally – but my first thought was one of a little bit of surprise. I was a little bit surprised that here I was, Ed Hillary, on top of Mt. Everest. After all, this is the ambition of most mountaineers.

If a subject excites us, if it stirs our deepest curiosity, or if we have to learn because the stakes are high, we pay much more attention. What we absorb sinks in.

We shall require a substantially new manner of thinking if mankind is to survive.

I have no special talent. I am only passionately curious.

Of mankind we may say in general they are fickle, hypocritical, and greedy of gain.

Even if you’re happy with the life you’ve chosen, you’re still curious about the other options.

We should not teach children the sciences; but give them a taste for them.

With fools, there is no companionship. Rather than to live with men who are selfish, vain, quarrelsome, and obstinate, let a man walk alone.

I think it’s a very good thing to leave your country and look at it from afar.

Space is almost infinite. As a matter of fact, we think it is infinite.

I have wanted to fly into space for many years, but never imagined it would really be feasible.

It is not necessary that you leave the house. Remain at your table and listen. Do not even listen, only wait. Do not even wait, be wholly still and alone. The world will present itself to you for its unmasking, it can do no other, in ecstasy it will writhe at your feet.

We will build new ships to carry man forward into the universe, to gain a new foothold on the moon and to prepare for new journeys to the worlds beyond our own.

Let’s pray that the human race never escapes from Earth to spread its iniquity elsewhere.

Unfortunately, the highly curious student is a small percentage of the kids.

Space ails us moderns: we are sick with space.

The important thing is not to stop questioning. Curiosity has its own reason for existing.

You cannot be creative with people around you.

A queer fellow and a jolly fellow is the grasshopper. Up the mountains he comes on excursions, how high I don’t know, but at least as far and high as Yosemite tourists.

Nine times out of ten, in the arts as in life, there is actually no truth to be discovered; there is only error to be exposed.

Following the light of the sun, we left the Old World.

There’s a certain amount of freedom involved in cycling: you’re self-propelled and decide exactly where to go. If you see something that catches your eye to the left, you can veer off there, which isn’t so easy in a car, and you can’t cover as much ground walking.

The moon and other celestial bodies should be free for exploration and use by all countries. No country should be permitted to advance a claim of sovereignty.

Adventure is not outside man; it is within.

I’d like to be the last person alive in the world! Yes, I’d like to know what happens.

Fanatics are picturesque, mankind would rather see gestures than listen to reasons.

What we want is to see the child in pursuit of knowledge, and not knowledge in pursuit of the child.

Often people display a curious respect for a man drunk, rather like the respect of simple races for the insane… There is something awe-inspiring in one who has lost all inhibitions.

God is absence. God is the solitude of man.

Children are remarkable for their intelligence and ardor, for their curiosity, their intolerance of shams, the clarity and ruthlessness of their vision.

Adventure is worthwhile in itself.

Truth is a pathless land.

America had often been discovered before Columbus, but it had always been hushed up.

Imagination will often carry us to worlds that never were. But without it we go nowhere.

What I have is a malevolent curiosity. That’s what drives my need to write and what probably leads me to look at things a little askew. I do tend to take a different perspective from most people.

I love trying new things.

SpaceX is only 12 years old now. Between now and 2040, the company’s lifespan will have tripled. If we have linear improvement in technology, as opposed to logarithmic, then we should have a significant base on Mars, perhaps with thousands or tens of thousands of people.

We need to know what the resources of the moon are. We have great evidence now because of different kinds of radar and spectroscopic analysis that people have been able to do. But we really do need to go visit there, and we can do that with a robot craft without any problem.

We sail within a vast sphere, ever drifting in uncertainty, driven from end to end.

When we understand string theory, we will know how the universe began. It won’t have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.

Even philosophers will praise war as ennobling mankind, forgetting the Greek who said: ‚War is bad in that it begets more evil than it kills.‘
