Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.
— Neil deGrasse Tyson
I was born the same week NASA was founded, so we're the same age and feel some of the same pains, joys, and frustrations.
For centuries, magicians have intuitively taken advantage of the inner workings of our brains.
There is no greater education than one that is self-driven.
Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
Space in general gave us GPS - that's not specifically NASA, but it's investments in space.
The urge to miniaturize electronics did not exist before the space program. I mean our grandparents had radios that was furniture in the living room. Nobody at the time was saying, 'Gee, I want to carry that in my pocket.' Which is a non-thought.
For me, the most fascinating interface is Twitter. I have odd cosmic thoughts every day and I realized I could hold them to myself or share them with people who might be interested.
Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or 1,000 years?' Biology isn't there yet with that kind of predictive precision.
Space exploration is a force of nature unto itself that no other force in society can rival.
The history of exploration across nations and across time is not one where nations said, 'Let's explore because it's fun.' It was, 'Let's explore so that we can claim lands for our country, so that we can open up new trade routes; let's explore so we can become more powerful.'
Computers have proved to be formidable chess players. In fact, they've beaten our top human chess champions.
Everything we do, every thought we've ever had, is produced by the human brain. But exactly how it operates remains one of the biggest unsolved mysteries, and it seems the more we probe its secrets, the more surprises we find.
There are thousands of asteroids whose orbit in the Solar System crosses that of Earth. And we have a little acronym for them - NEOs: near Earth objects. And our biggest goal is to try to catalogue them, so we know in advance if one is going to put us at risk.
As a scientist, I want to go to Mars and back to asteroids and the Moon because I'm a scientist. But I can tell you, I'm not so naive a scientist to think that the nation might not have geopolitical reasons for going into space.
When you innovate, you create new industries that then boost your economy. And when you create new industries and that becomes part of your culture, your jobs can't go overseas because no one else has figured out how to do it yet.
No one wants to die, and no one wants to die poor. These are the two fundamental truths that transcend culture, they transcend politics, they transcend economic cycles.
Kids are born curious about the world. What adults primarily do in the presence of kids is unwittingly thwart the curiosity of children.
The most creative people are motivated by the grandest of problems that are presented before them.
Once you have an innovation culture, even those who are not scientists or engineers - poets, actors, journalists - they, as communities, embrace the meaning of what it is to be scientifically literate. They embrace the concept of an innovation culture. They vote in ways that promote it. They don't fight science and they don't fight technology.
If you want a nation to have space exploration ambitions, you've got to send humans.
It turns out our brain is sensitive, maybe too sensitive, to motion. It's a survival mechanism.
Space only becomes ordinary when the frontier is no longer being breached.
Science is basically an inoculation against charlatans.
All the traditional STEM fields, the science, technology, engineering, and math fields, are stoked when you dream big in an agency such as NASA.
We didn't go to the moon to explore or because it was in our DNA or because we're Americans. We went because we were at war and we felt a threat.
All tweets are tasty. Any tweet anybody writes is tasty. So, I try to have each tweet not simply be informative, but have some outlook, some perspective that you might not otherwise had.
The caricature of science is that we hold tight to the theories we have, and shun challenges to them. That's just not true. In fact, we hold our highest rewards for those scientists who can prove others wrong. And by the way, they are famous in their own lifetimes. We don't wait until they're dead.
We live on this speck called Earth - think about what you might do, today or tomorrow - and make the most of it.
No one is dumb who is curious. The people who don't ask questions remain clueless throughout their lives.
