Science Space Quotes

Space has no top, no bottom; in fact, it is bottomless both at the bottom and the top. ~ Edgar Wilson Nye

A time will come when men will stretch out their eyes. They should see planets like our Earth. ~ Christopher Wren

We're going to be focusing our science on things that will take us farther and longer into space. For many of those experiments, the crew members are human guinea pigs, which is fine; that's part of my job. I don't mind being a human guinea pig. ~ John L. Phillips

One of the most striking results of modern investigation has been the way in which several different and quite independent lines of evidence indicate that a very great event occurred about two thousand million years ago. The radio-active evidence for the age of meteorites; and the estimated time for the tidal evolution of the Moon's orbit (though this is much rougher), all agree in their testimony, and, what is far more important, the red-shift in the nebulae indicates that this date is fundamental, not merely in the history of our system, but in that of the material universe as a whole. ~ Henry Norris Russell

Gagarin flew into space, but didn't see any god there. ~ Nikita Khrushchev

The partisanship surrounding space exploration and the retrenching of U.S. space policy are part of a more general trend: the decline of science in the United States. As its interest in science wanes, the country loses ground to the rest of the industrialized world in every measure of technological proficiency. ~ Neil DeGrasse Tyson

The views of the Earth are really beautiful. If you've ever seen a space IMAX movie, that's really what it looks like. I wish I'd had more time just to sit and look out the window with a map, but our science program kept us very busy in the lab most of the time. ~ David M. Brown

By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang. ~ Carl Sagan

National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars. ~ Carl Sagan

As I looked out at the glittering waters of the Pacific I was seeing for Carl. He knew that it's not for any one generation to see the completed picture. That's the point. The picture is never completed. There is always so much more that remains to be discovered. ~ Ann Druyan

The people who built the space program - both Soviet and U.S. - were readers of science fiction. ~ Gregory Benford

There is no time. There is no space. There is no condition. There is only awareness, awareness of these ideas. ~ Frederick Lenz

Forget scientists. The next space launch we should send up painters, poets and musicians. I'd be more interested in what they discover than anything that takes place in a test tube. ~ James Rozoff

At the very moment that humans discovered the scale of the universe and found that their most unconstrained fancies were in fact dwarfed by the true dimensions of even the Milky Way Galaxy, they took steps that ensured that their descendants would be unable to see the stars at all. For a million years humans had grown up with a personal daily knowledge of the vault of heaven. In the last few thousand years they began building and emigrating to the cities. In the last few decades, a major fraction of the human population has abandoned a rustic way of life. As technology developed and the cities were polluted, the nights became starless. New generations grew to maturity wholly ignorant of the sky that had transfixed their ancestors and that had stimulated the modern age of science and technology. Without even noticing, just as astronomy entered a golden age most people cut themselves off from the sky, a cosmic isolationism that ended only with the dawn of space exploration. ~ Carl Sagan

'Floating Worlds,' published in 1975 and the lone science fiction novel by acclaimed historical novelist Cecelia Holland, was unique in being completely devoid of the usual pulp influences present in much space opera up to that time. ~ Pamela Sargent

From a philosophical point of view, Leibniz's most interesting argument was that absolute space conflicted with what he called the principle of the identity of indiscernibles (PII). PII says that if two objects are indiscernible, then they are identical, i.e. they are really one and the same object. What does it mean to call two objects indiscernible? It means that no difference at all can be found between them--they have exactly the same attributes. So if PII is true, then any two genuinely distinct objects must differ in at least one of their attributes--otherwise they would be one, not two. PII is intuitively quite compelling. It certainly is not easy to find an example of two distinct objects that share all their attributes. Even two mass-produced factory goods will normally differ in innumerable ways, even if the differences cannot be detected with the naked eye.

Leibniz asks us to imagine two different universes, both containing exactly the same objects. In Universe One, each object occupies a particular location in absolute space.In Universe Two, each object has been shifted to a different location in absolute space, two miles to the east (for example). There would be no way of telling these two universes apart. For we cannot observe the position of an object in absolute space, as Newton himself admitted. All we can observe are the positions of objects relative to each other, and these would remain unchanged--for all objects are shifted by the same amount. N ~ Samir Okasha

One of the key principles of the Outer Space Treaty is that space is the common heritage of humanity and cannot be owned by anyone – government, nation, individual or corporation. Space is very colonial: we talk of the 'conquest' of space, the 'high frontier' or the 'final frontier', colonising other planets, and the innate urge of human beings to explore, often without thinking about it; it's such a strong master narrative. Instead of considering the treaty to be outdated, we might equally think of it as a radical statement of equality and justice – and one we need more than ever. ~ Alice Gorman

Science fiction writers didn't predict the fade-out of NASA's manned space operations, and they weren't prepared with alternative routes to space when that decline became undeniable. ~ Gregory Benford

It doubtless seems highly paradoxical to assert that Time is unreal, and that all statements which involve its reality are erroneous. Such an assertion involves a far greater departure from the natural position of mankind than is involved in the assertion of the unreality of Space or of the unreality of Matter. So decisive a breach with that natural position is not to be lightly accepted. And yet in all ages the belief in the unreality of time has proved singularly attractive. ~ J.M.E. McTaggart

It is altogether reasonable to conclude that the heavenly bodies, alias worlds, which move or are situate within the circle of our knowledge, as well all others throughout immensity, are each and every one of them possessed or inhabited by some intelligent agents or other, however different their sensations or manners of receiving or communicating their ideas may be from ours, or however different from each other. ~ Ethan Allen

What got my interested in science fiction was actually the American space program. ~ Ronald D. Moore

In all the Kalahari Desert, only six true hunters remained. The renegades agreed to let Louis hang around, an offer he took to the extreme; once installed, Louis acted like an unemployed in-law, basically squatting with the Bushmen for the next four years ... He learned to keep his campfire burning and tent zipped even on the most sweltering nights, since packs of hyenas were known to drag people from open shelters and tear out their throats. He leaned that if you stumble upon an angry lioness and her cubs, you stand tall and make her back down, but in the same situation with a rhino, you run like hell. (p. 234) Know why people run marathons? he said ... Because running is rooted in our collective imagination, and our imagination is rooted in running. Language, art, science; space shuttles ... intravascular surgery, they all had their roots in our ability to run. Running was the superpower that made us human- which means it's a superpower all humans possess. (p. 239) ~ Christopher McDougall

Birds know, better than humans, not to spoil the nest. ~ Carl Sagan

His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic?

We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth.

… But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter.

His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of con ~ Walter Lewin

...she was struck suddenly that he wasn't unfathomable at all. They were both made of the same star stuff. The same primordial fires that had coalesced to form their respective planets had been so close, on a grand cosmic scale. A near-infinite universe, and they were practically next-door neighbors. Looking into his eyes was like looking into ten billion years of history, like she could see the particles and rocks and gasses coalesce over eons, until somehow, impossibly, here they both were. ~ Lindsay Ellis

We see it [the as-yet unseen, probable new planet, Neptune] as Columbus saw America from the coast of Spain. Its movements have been felt, trembling along the far-reaching line of our analysis with a certainty hardly inferior to that of ocular demonstration. ~ William Herschel

When we talk about dystopias, especially in young adult fiction, a lot of them are essentially science fictional futures. They aren't necessarily tied to the traditional concept of dystopia. And so in that space, my impression is that kids love reading about weird, wild, adventurous places, and dystopia fits that bill. ~ Paolo Bacigalupi

A common misconception about how things such as space shuttles come to be is that engineers simply apply the theories and equations of science. But this cannot be done until the new thing-to-be is conceived in the engineer's mind's eye. Rather than following from science, engineered things lead it. ~ Henry Petroski

Using material ferried up by rockets, it would be possible to construct a "space station" in ... orbit. The station could be provided with living quarters, laboratories and everything needed for the comfort of its crew, who would be relieved and provisioned by a regular rocket service. (1945) ~ Arthur C. Clarke

Houston, Tranquillity Base here. The Eagle has landed. ~ Neil Armstrong

Space flight still had a long way to go to catch up with the safety record of the milkshake industry. ~ Kevin Fong

It appears that the solution of the problem of time and space is reserved to philosophers who, like Leibniz, are mathematicians, or to mathematicians who, like Einstein, are philosophers. ~ Hans Reichenbach

If the whole world shared such experiences, we would then have common dreams and everybody could begin thinking about tomorrow. And if everybody thinks about tomorrow, then someday we can visit the sky together. ~ Neil DeGrasse Tyson

Another ship. It's the best news I could ever have imagined.

Who are they going to send? Who's coming?

I stare out of the helm window, straining my eyes against the infinite blackness, pressing my fingernails into my palms so hard they sting. I can't see anything except the silver pinprick stars.

How long until I'll be able to see The Eternity?

How long until it will be able to see me? ~ Lauren James

It would take a civilization far more advanced than ours, unbelievably advanced, to begin to manipulate negative energy to create gateways to the past. But if you could obtain large quantities of negative energy - and that's a big "IF" - then you could create a time machine that apparently obeys Einstein's equation and perhaps the laws of quantum theory. ~ Michio Kaku

But we must not forget that all things in the world are connected with one another and depend on one another, and that we ourselves and all our thoughts are also a part of nature. It is utterly beyond our power to measure the changes of things by time. Quite the contrary, time is an abstraction, at which we arrive by means of the change of things; made because we are not restricted to any one definite measure, all being interconnected. A motion is termed uniform in which equal increments of space described correspond to equal increments of space described by some motion with which we form a comparison, as the rotation of the earth. A motion may, with respect to another motion, be uniform. But the question whether a motion is in itself uniform, is senseless. With just as little justice, also, may we speak of an "absolute time" --- of a time independent of change. This absolute time can be measured by comparison with no motion; it has therefore neither a practical nor a scientific value; and no one is justified in saying that he knows aught about it. It is an idle metaphysical conception. ~ Ernst Mach

I have looked farther into space than ever a human being did before me. ~ William Herschel

In the past, it was only in science fiction novels that you could read about ordinary people being able to go to space ... But you laid the foundation for space tourism. ~ Nursultan Nazarbayev

I'm convinced that before the year 2000 is over, the first child will have been born on the moon. ~ Wernher Von Braun

Know why people run marathons? he told Dr. Bramble. Because running is rooted in our collective imagination, and our imagination is rooted in running. Language, art, science; space shuttles, Starry Night, intravascular surgery; they all had their roots in our ability to run. Running was the superpower that made us human - which means it's a superpower all humans possess. ~ Christopher McDougall

All incarnations are lived at once, and yet there does seem to be a linear sense of time when you're in the vortex of time and space, when your consciousness is fixated in a body. ~ Frederick Lenz

[Coleridge] selected an instance of what was called the sublime, in DARWIN, who imagined the creation of the universe to have taken place in a moment, by the explosion of a mass of matter in the womb, or centre of space. In one and the same instant of time, suns and planets shot into systems in every direction, and filled and spangled the illimitable void! He asserted this to be an intolerable degradation -referring, as it were, all the beauty and harmony of nature to something like the bursting of a barrel of gunpowder! that spit its combustible materials into a pock-freckled creation! ~ Samuel Taylor Coleridge

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.
[Having identified Uranus (1781), the first planet discovered since antiquity.] ~ William Herschel

Asked in 1919 whether it was true that only three people in the world understood the theory of general relativity, [Eddington] allegedly replied: 'Who's the third? ~ Arthur Stanley Eddington

The history of astronomy is a history of receding horizons. ~ Edwin Powell Hubble

The claim that the universe *began* with the big bang has no basis in current physical and cosmological knowledge. The observations confirming the big bang do not rule out the possibility of a prior universe. ~ Victor J. Stenger

I find these comparisons particularly poignant: life versus death, hope versus fear. Space exploration and the highly mechanized destruction of people use similar technology and manufacturers, and similar human qualities of organization and daring. Can we not make the transition from automated aerospace killing to automated aerospace exploration of the solar system in which we live? ~ Carl Sagan

How many extraordinary phenomena like this, so foreign to human comprehension, might lie concealed in space? Do we need to travel everywhere bringing destructive power on our ships, so as to smash anything that runs counter to our understanding? ~ Stanislaw Lem

Human eyes have not yet reached as far as they can go with a telescope, nor have they seen everything there is to see with a microscope. ~ Omer Toledano

If I had unlimited funds, wall space and storage, I would collect a lot more things, like 'Planet of the Apes,' 'Star Wars,' science fiction stuff, autographs, and prop guns and weapons. I have to draw the line somewhere. ~ Kirk Hammett

As a kid, I was obsessed with space. Well, I was obsessed with nuclear science too, to a point, but before that, I was obsessed with space, and I was really excited about, you know, being an astronaut and designing rockets, which was something that was always exciting to me. ~ Taylor Wilson

In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie.
[Dedication to Sagan's wife, Ann Druyan, in Cosmos] ~ Carl Sagan

Mars and my own stupidity keep trying to kill me. ~ Andy Weir

Science fiction was rocket-mad for about 40 years until aerospace hit a brick wall about 1970. I would not write off space colonisation or exploration completely, but we are profoundly ill adapted for going boldly into outer space. ~ Charles Stross

For the moment we might very well can them DUNNOS (for Dark Unknown Nonreflective Nondetectable Objects Somewhere). ~ Bill Bryson

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that. ~ Michio Kaku

We do a lot of science on the space station. Over the course of the year, there'll be 400 to 500 different investigations in all different kinds of disciplines. Some are related to improving life on earth in material science, physics, combustion science, earth sciences, medicine. ~ Scott Kelly

Some people think emotionally more often than they think politically. Some think politically more often than they think rationally. Others never think rationally about anything at all.
No judgment implied. Just an observation. ~ Neil DeGrasse Tyson

But who can quantify
the algebra of space,
or weigh those worlds that swim
each in its place?
Who can outdo the dark?
And what computer knows
how beauty comes to birth -
shell star and rose?

-Technicians by Jean Kenward ~ John Foster

The venture into space is meaningless unless it coincides with a certain interior expansion, an ever-growing universe within, to correspond with the far flight of the galaxies our telescopes follow from without. ~ Loren Eiseley

How far back to the elementary school core curriculum do we have to go to get someone on the House Committee on Science, Space and Technology caught up? ~ Jon Stewart

The ability of the humans to not only function in space but be very functional when they arrive at their destination, those are the kinds of things we're learning from the science. Fuel transfer technologies and all the things we can learn about the space environment are all valuable to us for pressing on out. ~ Kevin A. Ford

Seeing the space future through science fiction can be difficult. Much science fiction of the early era, the 1950s through the '70s, took an expansionist view. ~ Gregory Benford

People are fascinated by space flight. It makes them interested in science, gets them asking questions and motivates them. ~ Helen Sharman

She noted, more than once, that the meteor shower was happening, beyond the overcast sky, even if we could not see it. Who cares if she can kiss? She can see through the clouds. ~ John Green

From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lo ~ Carl Sagan

….. Neptune, the outermost planet.
No, it's not Pluto. Get over it. ~ Neil DeGrasse Tyson

The cosmic perspective not only embraces our genetic kinship with all life on Earth but also values our chemical kinship with any yet-to-be discovered life in the universe, as well as our atomic kinship with the universe itself. ~ Neil DeGrasse Tyson

Science literacy is being plugged into the forces that power the universe. There is no excuse for thinking that the Sun, which is a million times the size of Earth, orbits Earth. ~ Neil DeGrasse Tyson

A man that is of Copernicus' Opinion, that this Earth of ours is a Planet, carry'd round and enlightn'd by the Sun, like the rest of them, cannot but sometimes have a fancy ... that the rest of the Planets have their Dress and Furniture, nay and their Inhabitants too as well as this Earth of ours. ... But we were always apt to conclude, that 'twas in vain to enquire after what Nature had been pleased to do there, seeing there was no likelihood of ever coming to an end of the Enquiry ... but a while ago, thinking somewhat seriously on this matter (not that I count my self quicker sighted than those great Men [of the past], but that I had the happiness to live after most of them) me thoughts the Enquiry was not so impracticable nor the way so stopt up with Difficulties, but that there was very good room left for probable Conjectures. ~ Christiaan Huygens

The quantum is that embarrassing little piece of thread that always hangs from the sweater of space-time. Pull it and the whole thing unravels. ~ Fred Alan Wolf

Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy.
Heat, like gravity, penetrates every substance of the universe, its rays occupy all parts of space. The object of our work is to set forth the mathematical laws which this element obeys. The theory of heat will hereafter form one of the most important branches of general physics. ~ Joseph Fourier

When I grew up, I saw the moon landing, and I was fascinated watching them as a child, and that's what really turned me onto space and science fiction, and I started watching things like 'Lost In Space,' and that led me to 'Star Trek,' which was a major influence on my life. ~ Ronald D. Moore

The more of us that feel the universe, the better off we will be in this world. ~ Neil DeGrasse Tyson

We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects. ~ Laurel Clark

While most branches of science have ascended in this era, the field of astrophysics persistently rises to the top. I think I know why. At one time or another every one of us has looked up at the night sky and wondered: What does it all mean? How does it all work? And, what is my place in the universe? ~ Neil DeGrasse Tyson

Do you ever look up at the stars and try to contemplate the ends of the universe? ~ Ruth Ahmed

The aether: Invented by Isaac Newton, reinvented by James Clerk Maxwell. This is the stuff that fills up the empty space of the universe. Discredited and discarded by Einstein, the aether is now making a Nixonian comeback. It's really the vacuum, but burdened by theoretical, ghostly particles. ~ Leon M. Lederman

My body was a buzzing antenna into which radio waves flooded from the entire cosmos. I was the living switchboard of the universe. My skull was a magnetized globe. ~ Simon Critchley

On the Soyuz, there's simply not room to fly someone whose main contribution is expertise in a single area. The Russian rocket ship only carries three people, and between them they need to cover off a huge matrix of skills. Some are obvious: piloting the rocket, spacewalking, operating the robotic elements of the ISS like Canadarm2, being able to repair things that break on Station, conducting and monitoring the numerous scientific experiments on board. But since the crew is going to be away from civilization for many months, they also need to be able to do things like perform basic surgery and dentistry, program a computer and rewire an electrical panel, take professional-quality photographs and conduct a press conference - and get along harmoniously with colleagues, 24/7, in a confined space. ~ Chris Hadfield

You know that song, 'Woodstock.' It says 'We are stardust.' And we are. We come from stardust. Everything on earth is just ashes. ~ Priscille Sibley

Discover the force of the skies O Men: once recognised it can be put to use. ~ Johannes Kepler

The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of the worlds - to say nothing of stars or galaxies - humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal ~ Carl Sagan

Doing what has never been done before is intellectually seductive, whether or not we deem it practical. ~ Neil DeGrasse Tyson

Black holes are the last vestige of civilizations obsessed with tinkering. ~ Kane Freeman

One may characterize physics as the doctrine of the repeatable, be it a succession in time or the co-existence in space. The validity of physical theorems is founded on this repeatability. ~ Friedrich Hund

NASA spent millions of dollars inventing the ball-point pen so they could write in space. The Russians took a pencil. ~ Will Chabot

How strange it was, I thought, that when the tiny though thousandfold beauties of the Earth disappeared and the immeasurable beauty of outer space rose in the distant quiet splendor of light, man and the greatest number of other creatures were supposed to be asleep! Was it because we were only permitted to catch a fleeting glimpse of those great bodies and then only in the mysterious time of a dream world, those great bodies about which man had only the slightest knowledge but perhaps one day would be permitted to examine more closely? Or was it permitted for the great majority of people to gaze at the starry firmament only in brief, sleepless moments so that the splendor wouldn't become mundane, so that the greatness wouldn't be diminished? ~ Adalbert Stifter

Bohr's standpoint, that a space-time description is impossible, I reject a limine. Physics does not consist only of atomic research, science does not consist only of physics, and life does not consist only of science. The aim of atomic research is to fit our empirical knowledge concerning it into our other thinking. All of this other thinking, so far as it concerns the outer world, is active in space and time. If it cannot be fitted into space and time, then it fails in its whole aim and one does not know what purpose it really serves. ~ Erwin Schrodinger

Any life-form advanced enough to travel light-years through interstellar space would have nothing to learn by probing the rectums of farmers in Kansas. ~ Dan Brown

I look forward to the day when the solar system becomes our collective backyard - explored not only with robots, but with the mind, body, and soul of our species. ~ Neil DeGrasse Tyson

I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind. ~ D.H. Lawrence

It's hard to build models of inflation that don't lead to a multiverse. It's not impossible, so I think there's still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously. ~ Alan Guth

He also telephoned the Real Time Computer Complex on the ground floor of the Operations Wing to ask that an additional big I.B.M. computer be brought onto the line. ~ Henry S.F. Cooper Jr.

The concept of an independent system is a pure creation of the imagination. For no material system is or can ever be perfectly isolated from the rest of the world. Nevertheless it completes the mathematician's "blank form of a universe" without which his investigations are impossible. It enables him to introduce into his geometrical space, not only masses and configurations, but also physical structure and chemical composition. Just as Newton first conclusively showed that this is a world of masses, so Willard Gibbs first revealed it as a world of systems. ~ Lawrence Joseph Henderson

Our ultimate analysis of space leads us not to a "here" and a "there," but to an extension such as that which relates "here" and "there." To put the conclusion rather crudely-space is not a lot of points close together; it is a lot of distances interlocked. ~ Arthur Eddington

To move forward, what's required is a unified space agenda based on exploration, science, development, commerce, and security. ~ Buzz Aldrin

Problem Boats
We keep extra boats stuck to these doors for people to use if there's a problem that makes them not want to be in space anymore, but no one will come get them. ~ Randall Munroe

The space station here is a magical place and an incredible science facility. ~ Scott Kelly

Know why people run marathons? ... Because running is rooted in our collective imagination, and our imagination is rooted in running. Language, art, science; space shuttles, Starry Night, intravascular surgery; they all had their roots in our ability to run. Running was the superpower that made us human - which means its a superpower all humans posses. ~ Christopher McDougall
