Spacecraft Quotes

He sounds like a politician running for office.

Me," Artemis blurted. "I'm the nut." Artemis could have sworn the squid winked at him before bringing the five-ton chunk of spacecraft swinging down toward the morsel of meat in its blue shell. "I'm the nut!" Artemis shouted again, a little hysterically, it must be said.

There aren’t many people who can say they’ve vandalized a three-billion-dollar spacecraft, but I’m one of them.

Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.

An incomplete list: No more diving into pools of chlorinated water lit green from below. No more ball games played out under floodlights. No more porch lights with moths fluttering on summer nights. No more trains running under the surface of cities on the dazzling power of the electric third rail. No more cities. No more films, except rarely, except with a generator drowning out half the dialogue, and only then for the first little while until the fuel for the generators ran out, because automobile gas goes stale after two or three years. Aviation gas lasts longer, but it was difficult to come by. No more screens shining in the half-light as people raise their phones above the crowd to take pictures of concert states. No more concert stages lit by candy-colored halogens, no more electronica, punk, electric guitars. No more pharmaceuticals. No more certainty of surviving a scratch on one's hand, a cut on a finger while chopping vegetables for dinner, a dog bite. No more flight. No more towns glimpsed from the sky through airplane windows, points of glimmering light; no more looking down from thirty thousand feet and imagining the lives lit up by those lights at that moment. No more airplanes, no more requests to put your tray table in its upright and locked position – but no, this wasn't true, there were still airplanes here and there. They stood dormant on runways and in hangars. They collected snow on their wings. In the cold months, they were ideal for food storage. In summer the ones near orchards were filled with trays of fruit that dehydrated in the heat. Teenagers snuck into them to have sex. Rust blossomed and streaked. No more countries, all borders unmanned. No more fire departments, no more police. No more road maintenance or garbage pickup. No more spacecraft rising up from Cape Canaveral, from the Baikonur Cosmodrome, from Vandenburg, Plesetsk, Tanegashima, burning paths through the atmosphere into space. No more Internet. No more social media, no more scrolling through litanies of dreams and nervous hopes and photographs of lunches, cries for help and expressions of contentment and relationship-status updates with heart icons whole or broken, plans to meet up later, pleas, complaints, desires, pictures of babies dressed as bears or peppers for Halloween. No more reading and commenting on the lives of others, and in so doing, feeling slightly less alone in the room. No more avatars.

In space flight, “attitude” refers to orientation: which direction your vehicle is pointing relative to the Sun, Earth and other spacecraft. If you lose control of your attitude, two things happen: the vehicle starts to tumble and spin, disorienting everyone on board, and it also strays from its course, which, if you’re short on time or fuel, could mean the difference between life and death. In the Soyuz, for example, we use every cue from every available source—periscope, multiple sensors, the horizon—to monitor our attitude constantly and adjust if necessary. We never want to lose attitude, since maintaining attitude is fundamental to success. In my experience, something similar is true on Earth. Ultimately, I don’t determine whether I arrive at the desired professional destination. Too many variables are out of my control. There’s really just one thing I can control: my attitude during the journey, which is what keeps me feeling steady and stable, and what keeps me headed in the right direction. So I consciously monitor and correct, if necessary, because losing attitude would be far worse than not achieving my goal.

Q: What were you thinking when your colleagues were out there making cosmic history? A: I just kept reminding myself that every single component in this spacecraft was provided by the guy who submitted the cheapest tender.

We tend to hear much more about the splendors returned than the ships that brought them or the shipwrights. It has always been that way. Even those history books enamored of the voyages of Christopher Columbus do not tell much about the builders of the Nina the Pinta and the Santa Maria or about the principle of the caravel. These spacecraft their designers builders navigators and controllers are examples of what science and engineering set free for well-defined peaceful purposes can accomplish. Those scientists and engineers should be role models for an America seeking excellence and international competitiveness. They should be on our stamps.

When I applied to graduate school many years ago, I wrote an essay expressing my puzzlement at how a country that could put a man on the moon could still have people sleeping on the streets. Part of that problem is political will; we could take a lot of people off the streets tomorrow if we made it a national priority. But I have also come to realize that NASA had it easy. Rockets conform to the unchanging laws of physics. We know where the moon will be at a given time; we know precisely how fast a spacecraft will enter or exist the earth's orbit. If we get the equations right, the rocket will land where it is supposed to--always. Human beings are more complex than that. A recovering drug addict does not behave as predictably as a rocket in orbit. We don't have a formula for persuading a sixteen-year-old not to drop out of school. But we do have a powerful tool: We know that people seek to make themselves better off, however they may define that. Our best hope for improving the human condition is to understand why we act the way we do and then plan accordingly. Programs, organizations, and systems work better when they get the incentives right. It is like rowing downstream.

Apart from a thin film of life at the very surface of the Earth, an occasional intrepid spacecraft, and some radio static, our impact on the Universe is nil. It knows nothing of us.

On a plaque attached to the NASA deep space probe we [human beings] are described in symbols for the benefit of any aliens who might meet the spacecraft as “bilaterly symmetrical, sexually differentiated bipeds, located on one of the outer spiral arms of the Milky Way, capable of recognising the prime numbers and moved by one extraordinary quality that lasts longer than all our other urges—curiosity.

Planetary exploration satisfies our inclination for great enterprises and wanderings and quests that has been with us since our days as hunters and gatherers on the East African savannahs a million years ago. By chance—it is possible, I say, to imagine many skeins of historical causality in which this would not have transpired—in our age we are able to begin again. Exploring other worlds employs precisely the same qualities of daring, planning, cooperative enterprise, and valor that mark the finest in military tradition. Never mind the night launch of an Apollo spacecraft bound for another world. That makes the conclusion foregone. Witness mere F-14s taking off from adjacent flight decks, gracefully canting left and right, afterburners flaming, and there’s something that sweeps you away—or at least it does me. And no amount of knowledge of the potential abuses of carrier task forces can affect the depth of that feeling. It simply speaks to another part of me. It doesn’t want recriminations or politics. It just wants to fly.

I’ve never agreed with the conventional wisdom that ‘actors are great liars.’ If more people understood the acting process, the goals of good actors, the conventional wisdom would be ‘actors are terrible liars,’ because only bad actors lie on the job. The good ones hate fakery and avoid manufactured emotion at all costs. Any script is enough of a lie anyway. (What experience does any actor have with flying a spacecraft? Killing someone?) What’s called for, what actors are hired for, is to bring reality to the arbitrary.

A lot of kids owned their own interplanetary vehicles. School parking lots all over Ludus were filled with UFOs, TIE fighters, old NASA space shuttles, Vipers from Battlestar Galactica, and other spacecraft designs lifted from every sci-fi movie and TV show you can think of.

This Voyager spacecraft was constructed by the United States of America. We are a community of 240 million human beings among the more than 4 billion who inhabit the planet Earth. We human beings are still divided into nation states, but these states are rapidly becoming a single global civilization. We cast this message into the cosmos. It is likely to survive a billion years into our future, when our civilization is profoundly altered and the surface of the Earth may be vastly changed. Of the 200 billion stars in the Milky Way galaxy, some--perhaps many--may have inhabited planets and spacefaring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts, and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problems we face, to join a community of galactic civilizations. This record represents our hope and our determination, and our good will in a vast and awesome universe

It is of course dangerous to set off an explosive device on a spacecraft.

When I started writing I wanted the best tools. I skipped right over chisels on rocks, stylus on wet clay plates, quills and fountain pens, even mechanical pencils, and went straight to one of the first popular spin-offs of the aerospace program: the ballpoint pen. They were developed for comber navigators in the war because fountain pens would squirt all over your leather bomber jacket at altitude. (I have a cherished example of the next generation ballpoint, a pressurized Space Pen cleverly designed to work in weightlessness, given to me by Spider Robinson. At least, I cherish it when I can find it. It is also cleverly designed to seek out the lowest point of your desk, roll off, then find the lowest point on the floor, under a heavy piece of furniture. That's because it is cylindrical and lacks a pocket clip to keep it from rolling. In space, I presume it would float out of your pocket and find a forgotten corner of your spacecraft to hide in. NASA spent $3 million developing it. Good job, guys. I'm sure it's around here somewhere.)

My favorite parody of this gesture was a skit on NBC’s Saturday Night Live, shortly after the Voyager launch, in which they showed a written reply from the aliens who recovered the spacecraft. The note simply requested, “Send more Chuck Berry.

My grandmother used to say that flaws are God's greatest gift to humanity, because they give us the opportunity to learn from ourselves and from each other. She said they're not obstacles to perfection, merely signs and guideposts on the path we take in pursuit of it.' 'But if nobody's perfect, no matter how hard we try, then what's the point?' Harvey didn't look up; he was concentrating hard on his work. 'The universe is infinite; we'll never map its edges, yet NASA keeps on sending up spacecrafts,' he said, folding the metal precisely. 'The point is just to get a little closer.

No more countries, all borders unmanned. No more fire departments, no more police. No more road maintenance or garbage pickup. No more spacecraft rising up from Cape Canaveral, from the Baikonur Cosmodrome, from Vandenburg, Plesetsk, Tanegashima, burning paths through the atmosphere into space. No more Internet. No more social media, no more scrolling through litanies of dreams and nervous hopes and photographs of lunches, cries for help and expressions of contentment and relationship-status updates with heart icons whole or broken, plans to meet up later, pleas, complaints, desires, pictures of babies dressed as bears or peppers for Halloween. No more reading and commenting on the lives of others, and in so doing, feeling slightly less alone in the room. No more avatars.

Running to the spacecraft, he hugged Landing Strut B.

REENTERING SPACECRAFT HEAT UP because they’re compressing the air in front of them (not, as is commonly believed, because of air friction).

We were no longer riding a spacecraft, but a tiny bird, caught in a vast pit of tar, beating her wings so hard she risked leaving a piece of herself behind.

Folks,” he said, “this is going to be the most ‘ghetto’ spacecraft ever built. There

While landing a spacecraft on a planet via Skip Drive navigation was officially and strongly discouraged by the Colonial Union, the Colonial Defense Forces recognized the strategic value of sudden and unexpected arrivals.

Mapping the trajectory of a spacecraft is a relatively straightforward business, bounded only by the laws of physics. Mapping the trajectory of an idea through a political system, on the other hand, can be a dicey business.

Something else emerges from this discussion about us as human individuals: we're not fixed, stable intellects riding along peering at the world through the lenses of our eyes like the pilots of people-shaped spacecraft. We are affected constantly by what's going on around us. Whether our flexibility is based in neuroplasticity or in less dramatic aspects of the brain, we have to start acknowledging that we are mutable, persuadable and vulnerable to clever distortions, and that very often what we want to be is a matter of constant effort rather than attaining a given state and then forgetting about it. Being human isn't like hanging your hat on a hook and leaving it there, it's like walking in a high wind: you have to keep paying attention. You have to be engaged with the world.

Humanity’s first faster-than-light spacecraft crashed into Pluto and vaporised a significant portion of it. Oops. Pluto’s status as a planet had been a matter of contention since the early twenty-first century and had come close to starting the fourth world war at the beginning of the twenty-second century. Making it even smaller did absolutely nothing to help the situation, and humanity came five minutes, and one hasty phone call, from another world war.

imagine you are an astronaut alone in space. no planets in view. no spacecraft. no distant stars. no source of light. imagine the latent terror, the quiet of space, the strange sensation of floating, the unspeakable dark between wealth of stars.

MYTH506. | There is an American flag on the Moon. According to Buzz Aldrin, one of the astronauts who was on the Moon, he and Neil Armstrong accidentally placed the original American flag too close to their spacecraft, and when they took off, the flag was blown away.

Then, looking beyond the Earth itself to the magnificence of the larger scene, there was a startling recognition that the nature of the universe was not as I had been taught. My understanding of the separate distinctness and the relative independence of movement of those cosmic bodies was shattered. There was an upwelling of fresh insight coupled with a feeling of ubiquitous harmony-a sense of interconnectedness with the celestial bodies surrounding our spacecraft. Particular scientific facts about stellar evolution took on new significance.

Many people remember that when in 1977 the Voyager spacecraft was launched, opinions were canvassed as to what artefacts would be most appropriate to leave in outer space as a signal of man's cultural achievements on earth. The American astronomer Carl Sagan proposed that 'if we are to convey something of what humans are about then music has to be a part of it.' To Sagan's request for suggestions, the eminent biologist Lewis Thomas answered, 'I would send the complete works of Johann Sebastian Bach.' After a pause, he added, 'But that would be boasting.

The seven men pressed on. They were tired of the designation of “capsule” for the Mercury vehicle. The term as much as declared that the man inside was not a pilot but an experimental animal in a pod. Gradually, everybody began trying to work the term “spacecraft” into NASA publications and syllabuses. Next

Smart contracts on Ethereum are worse than even non-financial commercial code; as of May 2016, Ethereum contracts averaged 100 obvious bugs (so obvious a machine could spot them) per 1000 lines of code.348 (For comparison, Microsoft code averages 15 obvious bugs per 1000 lines, NASA spacecraft code around 0 per 500,000 lines.)

Then centrifugal gravity took over, and with something close to majesty the skeletal spacecraft descended out of the repair bay as smoothly and elegantly as a falling chandelier.

You see tools and parts and my arm shoved inside a small spacecraft, and you really have to ask what I’m doing?

NASA dubbed this spacecraft the Envoy I, and it reached Europa on the 9th of July, 1976—the day humanity made its first direct contact with an alien intelligence.

There aren't many people who can say they've vandalized a three-billion-dollar spacecraft, but I'm one of them.

Unmanned spacecraft must therefore use artificial intelligence software to make decisions in emergencies, because there’s no time to call home for help.

Much as in life, if you like someone, you’ll tend to overlook their flaws. You’ll find signals from a love interest—or a spacecraft—even when they’re not sending any.

We are too small and our statecraft is too feeble to be seen by a spacecraft between the Earth and the Moon. From this vantage point, our obsession with nationalism is nowhere in evidence.

And yet there is no sign of humans in this picture, not our reworking of the Earth’s surface, not our machines, not ourselves: We are too small and our statecraft is too feeble to be seen by a spacecraft between the Earth and the Moon. From this vantage point, our obsession with nationalism is nowhere in evidence. The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of 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.

I clearly had a few daddy issues myself, but you didn’t see me pulling the wings off of flies. On the other hand, I did have a slight anger-management problem, and a related history of physical violence, both well documented by the public school system. And, oh yeah, that whole “hallucinating alien spacecraft from my favorite videogame” thing. So perhaps I wasn’t in the best position to judge the sanity of others.

Hounslow, in a steel-and-smoked-glass office block with all its pipes on the outside. It nestled among the pebbledash housing estates like an abandoned spacecraft after a fruitless mission to find intelligent life.

When the members of the “Heaven’s Gate” cult failed to spot the spacecraft they knew must be trailing the comet Hale-Bopp, they returned the $4,000 telescope they had bought for this purpose, believing it to be defective.

In space flight, “attitude” refers to orientation: which direction your vehicle is pointing relative to the Sun, Earth and other spacecraft.

So I consciously monitor and correct, if necessary, because losing attitude would be far worse than not achieving my goal.

A more ambitious bet would be to learn from what we imagine a more mature civilization might have attempted. To take the small scientific leap and allow the possibility ‘Oumuamua was extraterrestrial technology is to give humanity the small nudge toward thinking like a civilization that could have left a lightsail buoy for our solar system to run into. It is to nudge us not just to imagine alien spacecraft but to contemplate the construction of our own such craft.

I blink a few times at what I’m seeing. I gulp. This…this is an alien spacecraft. Made by aliens. Aliens intelligent enough to make a spacecraft. Humanity isn’t alone in the universe. And I’ve just met our neighbors. “Holy fucking shit!

Here is one way to conceptualize NASA's heroic era: in 1961, Kennedy gave his "moon speech" to Congress, charging them to put an American on the moon "before the decade is out." In the eight years that unspooled between Kennedy's speech and Neil Armstrong's first historic bootprint, NASA, a newborn government agency, established sites and campuses in Texas, Florida, Alabama, California, Ohio, Maryland, Mississippi, Virginia, and the District of Columbia; awarded multi-million-dollar contracts and hired four hundred thousand workers; built a fully functioning moon port in a formerly uninhabited swamp; designed and constructed a moonfaring rocket, spacecraft, lunar lander, and space suits; sent astronauts repeatedly into orbit, where they ventured out of their spacecraft on umbilical tethers and practiced rendezvous techniques; sent astronauts to orbit the moon, where they mapped out the best landing sites; all culminating in the final, triumphant moment when they sent Neil Armstrong and Buzz Aldrin to step out of their lunar module and bounce about on the moon, perfectly safe within their space suits. All of this, start to finish, was accomplished in those eight years.

All right,” Malcolm said. “Let’s go back to the beginning.” He paused, staring at the ceiling. “Physics has had great success at describing certain kinds of behavior: planets in orbit, spacecraft going to the moon, pendulums and springs and rolling balls, that sort of thing. The regular movement of objects. These are described by what are called linear equations, and mathematicians can solve those equations easily. We’ve been doing it for hundreds of years.” “Okay,” Gennaro said. “But there is another kind of behavior, which physics handles badly. For example, anything to do with turbulence. Water coming out of a spout. Air moving over an airplane wing. Weather. Blood flowing through the heart. Turbulent events are described by nonlinear equations. They’re hard to solve—in fact, they’re usually impossible to solve. So physics has never understood this whole class of events. Until about ten years ago. The new theory that describes them is called chaos theory.

The Mars settlement may not grow that quickly, although the length of a sea voyage cross the Atlantic in the 1600's is comparable to the time it will take people to get to Mars on a spacecraft, and the cost, in relative terms, is not that different.

That place, called the heliopause, is one definition of the outer boundary of the Empire of the Sun. But the Voyager spacecraft will plunge on, penetrating the heliopause sometime in the middle of the twenty-first century, skimming through the ocean of space, never to enter another solar system, destined to wander through eternity far from the stellar islands and to complete its first circumnavigation of the massive center of the Milky Way a few hundred million years from now. We have embarked on epic voyages.

There is a phrase from World War I describing warfare as “months of boredom punctuated by moments of terror.” The same applies to long spacecraft missions. And it was a long and frankly terrifying hour as they awaited the hoped-for signal to return from New Horizons.

Small quantities of non-weapons-grade radioactive plutonium can be used to power radioisotope thermoelectric generators (sensibly abbreviated as RTGs) for spacecraft that travel to the outer solar system, where the intensity of sunlight has diminished below the level usable by solar panels. One pound of plutonium will generate a half million kilowatt-hours of heat energy, enough to continuously power a household blender for a hundred years, or a human being for five times as long, if we ran on nuclear fuel instead of grocery-store food.

Earth Defense Alliance ships were outfitted with reverse-engineered alien technology, including a Trägheitslosigkeit Field Generator, which created a small inertia-cancellation field around a spacecraft, by “harnessing the aligned spin of gyromagnetic particles to alter the curvature of space-time” or something.

All told, he made three perfect copies of the fuel bay I gave him. The only difference is the material. My original bays were made of aluminum. Someone on Stratt’s team had suggested a carbon-fiber hull but she shot that down. Well-tested technology only. Humanity had sixty-odd years of testing aluminum-hulled spacecraft.

It is conventional wisdom now that anything built by the government will be a disaster. But the two "Voyager" spacecraft were built by the government (in partnership with that other bugaboo, academia). They came in at cost, on time, and vastly exceeded their design specifications--as well as the fondest dreams of their makers. Seeking not to control, threaten, wound, or destroy, these elegant machines represented the exploratory part of our nature set free to roam the Solar System and beyond. This kind of technology, the treasures it uncovers freely available to all humans everywhere, has been, over the last few decades, one of the few activities of the United States admired as much by those who abhor many of its policies as by those who agree with it on every issue. "Voyager" cost each American less than a penny a year from launch to Neptune encounter. Missions to the planets are one of those things--and I mean this not just for the United States, but for the human species--that we do best.

Certain machines of extraordinary complexity have been built: spacecraft, for example, that sustain themselves for months in the void while performing complicated functions with great accuracy. But no machine has been made, nor can one be made, that has the source of its spontaneity within itself. A machine must be designed, constructed, and fueled.

There’ll be a sky full of babies and their shit, suspended overhead. You do not want to get caught in that rain when it falls.

The power of capitalist realism derives in part from the way that capitalism subsumes and consumes all of previous history: one effect of its 'system of equivalence' which can assign all cultural objects, whether they are religious iconography, pornography, or Das Kapital, a monetary value. Walk around the British Museum, where you see objects torn from their Iifeworlds and assembled as if on the deck of some Predator spacecraft, and you have a powerful image of this process at work. In the conversion of practices and rituals into merely aesthetic objects, the beliefs of previous cultures are objectively ironized, transformed into artifacts. Capitalist realism is therefore not a particular type of realism; it is more like realism in itself.

Jesse Marcel posed with some faked debris from an actual balloon and confessed to an error he never could have made, even on a bad day. It was a confession that would haunt him the rest of his life until, decades later and shortly before he died, he would retract his public story and restate that he had actually retrieved an alien spacecraft that night in the Roswell desert.

Investors include former Google CEO Eric Schmidt and Google cofounder Larry Page. Planetary Resources’ lead was followed in 2013 by a firm called Deep Space Industries. Its website currently looks like a science fiction film setting, with illustrations of CubeSats, scouting vehicles, and huge mining spacecraft assembled in space and never intended to enter a planet’s atmosphere.

One night, walking along 8th Street in the East Village, I saw some adolescent boys, out too late and unattended. They were playing an arcade video game set up on the sidewalk, piloting a digital spacecraft through starlit infinity, blasting everything in their path to bits. Now and then, the machine would let out a robotic shout of encouragement: You’re doing great! So the urchins flew on through the make-believe nothingness, destroying whatever they saw, hypnotized by the mechanical praise that stood in for the human voice of love. That, it seemed to me, was postmodernism in a nutshell. It ignored the full spiritual reality of life all around it in order to blow things apart inside a man-made box that only looked like infinity. You’re doing great, intellectuals! You’re doing great. Much

Make Believe When I wake up in the morning Not all is what it seems I drift through a world of make believe Between my real life and my dreams. Strange Adventures from the space book That I read the night before Crowd in upon on my drowsiness Through imagination's door. Between sleeping and waking The alarm clock's jangalang cry Becomes the roaring fire-railed rocket That hurls me through the sky. My bed's a silver spacecraft Which I pilot all alone Whisp'ring through endless stratospheres Towards planets still unknown. Outside through the mists of morning The spinning lights of cars In my make-believe space voyage Become eternities of stars. Is that my mother calling something That my dreams can't understand? Or can it be crackling instructions From far off Mission Command? Gareth Owen

Sometimes the gap between wrong and right is so negligible that we ignore it altogether. We pretend that the length of a day is 24 hours and that the ground beneath our feet is steady, when in fact the length of the day changes and Earth’s axis wobbles constantly as we hurtle around the sun at about 66,000 miles per hour and the sun moves around the center of the galaxy at about 500,000 miles per hour.

If a planetary twin of the Earth exists in space, it has eluded us so far. But we have found about fifty super-Earths so far. Kepler-452b, which was discovered by the Kepler spacecraft in 2015 and is about 1,400 light-years from us, is particularly interesting. It is 50 percent bigger than our planet, so you would weigh more than you do on the planet Earth, but otherwise, living there may not be so different from living on Earth.

As additional precautions, Kranz requested that a two-hundred-foot radio antenna (called a deep-space dish) in Australia be added to the global network tracking and communicating with the spacecraft, and that additional computers at the Goddard Space Flight Center in Maryland be what he called "cranked up" -- made ready for use. He also telephoned the Real Time Computer Complex on the ground floor of the Operations Wing to ask that an additional I.B.M. computer be brought onto the line.

There is an object blocking my view of the Petrova line. It’s right next to my ship. Maybe a few hundred meters away. It’s roughly triangle-shaped and it has gable-like protrusions along its hull. Yes. I said hull. It's not an asteroid- the lines are too smooth; too straight. This object was made. Fabricated. Constructed. Shapes like that don't occur in nature. It's a ship. Another ship. There's another ship in this system with me. Those flashes of light- those were its engines. It's Astrophage-powered. Just like the Hail Mary. But the design, the shape- it's nothing like any spacecraft I've ever seen. The whole thing is made of huge, flat surfaces- the worst possible way to make a pressure vessel. No one in their right mind would make a ship that shape. No one on Earth would, anyway. I blink a few times at what I'm seeing. I gulp. This... this is an alien spacecraft. Made by aliens. Aliens intelligent enough to make a spacecraft. Humanity isn't alone in the universe. And I've just met our neighbours. 'Holy fucking shit!

We invent and refine agriculture, without which almost all of us would starve to death. We create medicines and vaccines that save the lives of billions. We communicate at the speed of light, and whip around the Earth in an hour and a half. We have sent dozens of ships to more than seventy worlds, and four spacecraft to the stars. We are right to rejoice in our accomplishments, to be proud that our species has been able to see so far, and to judge our merit in part by the very science that has so deflated our pretensions.

Love is metaphysical gravity.” By Gary Zukav GUEST COMMENTATOR Bucky said, “Love is metaphysical gravity.” I agree. What else could it be? Without gravity you would float like an astronaut in a spacecraft. Up and down would mean nothing to you. Your slightest motion would send you tumbling head over feet or rolling uncontrollably. If you pushed hard against a wall, you would shoot backward fast until you hit another wall. If the lights in the spacecraft went out, you would have no way at all of orienting yourself. Without love the same thing happens. Every experience of anger, jealousy, resentment, and fear sends you spinning out of control. You have no way of knowing up from down except what your anger shows you, and it always shows you that you are right and someone else is wrong, that you are a victim and someone else is a villain. The more you act in anger, jealousy, resentment, or fear, the more painful consequences you create. You careen helplessly, spinning, rolling, hitting walls you can’t avoid and colliding with others. Love grounds you. It orients you. Love brings your awareness to others and yourself. Love opens your mind and heart to others and yourself. Love settles you and gives you balance. When you choose to become sensitive and caring instead of frightened and selfish, your anger turns to appreciation, your jealousy to gratitude, and your resentment to caring. You cannot loose your orientation: When your deeds harm others, you are in fear, and when you create harmony, cooperation, sharing, and reverence for Life, you are in love. The ground beneath you is always solid.

U.S. launch vehicles are these days too feeble to get such a spacecraft to Jupiter and beyond in only a few years by rocket propulsion alone. But if we’re clever (and lucky), there’s something else we can do: We can (as Galileo also did, years later) fly close to one world, and have its gravity fling us on to the next. A gravity assist, it’s called. It costs us almost nothing but ingenuity. It’s something like grabbing hold of a post on a moving merry-go-round as it passes—to speed you up and fling you in some new direction. The spacecraft’s acceleration is compensated for by a deceleration in the planet’s orbital motion around the Sun. But because the planet is so massive compared to the spacecraft, it slows down hardly at all. Each Voyager spacecraft picked up a velocity boost of nearly 40,000 miles per hour from Jupiter’s gravity. Jupiter in turn was slowed down in its motion around the Sun. By how much? Five billion years from now, when our Sun becomes a swollen red giant, Jupiter will be one millimeter short of where it would have been had Voyager not flown by it in the late twentieth century.

I think I would make a very good astronaut. To be a good astronaut you have to be intelligent and I’m intelligent. You also have to understand how machines work and I’m good at understanding how machines work. You also have to be someone who would like being on their own in a tiny spacecraft thousands and thousands of miles away from the surface of the earth and not panic or get claustrophobia or homesick or insane. And I really like little spaces, so long as there is no one else in them with me. Sometimes when I want to be on my own I get into the airing cupboard outside the bathroom and slide in beside the boiler and pull the door closed behind me and sit there and think for hours and it makes me feel very calm. So I would have to be an astronaut on my own, or have my own part of the space craft which no one else could come into. And also there are no yellow things or brown things in a space craft, so that would be okay too. And I would have to talk to other people from Mission Control, but we would do that through a radio linkup and a TV monitor, so they wouldn’t be like real people who are strangers, but it would be like playing a computer game. Also I wouldn’t be homesick at all because I’d be surrounded by things I like, which are machines and computers and outer space. And I would be able to look out of a little window in the spacecraft and know that there was no one near me for thousands and thousands of miles, which is what I sometimes pretend at night in the summer when I go and lie on the lawn and look up at the sky and I put my hands round the sides of my face so that I can’t see the fence and the chimney and the washing line and I can pretend I’m in space. And all I could see would be stars. And stars are the places where molecules that life is made of were constructed billions of years ago. For example, all the iron in your blood which keeps you from being anemic was made in a star. And I would like it if I could take Toby with me into space, and that might be allowed because they sometimes do take animals into space for experiments, so if I could think of a good experiment you could do with a rat that didn’t hurt the rat, I could make them let me take Toby. But if they didn’t let me I would still go because it would be a Dream Come True.

In conclusion, I return to Einstein. If we find a planet in the Alpha Centauri system, its image, captured by a camera travelling at a fifth of light speed, will be slightly distorted due to the effects of special relativity. It would be the first time a spacecraft has flown fast enough to see such effects. In fact, Einstein’s theory is central to the whole mission. Without it we would have neither lasers nor the ability to perform the calculations necessary for guidance, imaging and data transmission over twenty-five trillion miles at a fifth of light speed. We can see a pathway between that sixteen-year-old boy dreaming of riding on a light beam and our own dream, which we are planning to turn into a reality, of riding our own light beam to the stars. We are standing at the threshold of a new era. Human colonisation on other planets is no longer science fiction. It can be science fact. The human race has existed as a separate species for about two million years. Civilisation began about 10,000 years ago, and the rate of development has been steadily increasing. If humanity is to continue for another million years, our future lies in boldly going where no one else has gone before. I hope for the best. I have to. We have no other option.

If the mind was already oscillating and is energized further, then slowly it becomes concentrated, or, as we say in yoga, “one-pointed.” That is far better than the previous state. But the highest state is when the mind becomes conscious. In terms of instruments, it is not your computer, car, or spacecraft, but the human mind that is the most miraculous—if only you could use it consciously. The reason why success comes so easily and naturally for one person, and is a struggle for someone else, is essentially this: one person has organized his or her mind to think the way he wants, and another thinks against his or her own interests

After misapprehended natural events and hoaxes and psychological aberrations are removed from the data set, is there any residue of very credible but extremely bizarre cases, especially ones supported by physical evidence? Is there a "signal" hiding in all that noise? In my view, no signal has been detected. There are reliably reported cases that are unexotic, and exotic cases that are unreliable. There are no cases - despite well over a million UFO reports since 1947 - in which something so strange that it could only be an extraterrestrial spacecraft is reported so reliably that misapprehension, hoax, or hallucination can be reliably excluded.

The ‘tail’ of a comet, by the way, is a train of dust, but it is not streaming out behind the head of the comet as we might think. Instead, it is ‘blown’ by a stream of particles coming from the sun, which we call the solar wind. So the tail of the comet always points away from the sun, no matter which way the comet is travelling. There’s an exciting proposal, once confined to science fiction stories but now being implemented by Japanese space engineers, to use the solar wind to propel spacecraft equipped with gigantic ‘sails’. Like sailing yachts on the sea using real wind, solar wind space-yachts would theoretically provide a very economical way to travel to distant worlds.

In the spring of 1974 about two years before the Viking spacecraft landed on Mars, I was at a meeting in England sponsored by the Royal Society of London to explore the question of how to search for extraterrestrial life. During a coffee break, I noticed that a much larger meeting was being held in an adjacent hall, which out of curiosity I entered. I soon realized that I was witnessing one of the most ancient scholarly organizations on the planet. In the front row a young man in a wheelchair was, very slowly, signing his name in a book that bore on its earliest pages the signature of Isaac Newton. When at last he finished, there was a stirring ovation. Steven Hawking was a legend even then

Have you ever been in a place where history becomes tangible? Where you stand motionless, feeling time and importance press around you, press into you? That was how I felt the first time I stood in the astronaut garden at OCA PNW. Is it still there? Do you know it? Every OCA campus had – has, please let it be has – one: a circular enclave, walled by smooth white stone that towered up and up until it abruptly cut off, definitive as the end of an atmosphere, making room for the sky above. Stretching up from the ground, standing in neat rows and with an equally neat carpet of microclover in between, were trees, one for every person who’d taken a trip off Earth on an OCA rocket. It didn’t matter where you from, where you trained, where your spacecraft launched. When someone went up, every OCA campus planted a sapling. The trees are an awesome sight, but bear in mind: the forest above is not the garden’s entry point. You enter from underground. I remember walking through a short tunnel and into a low-lit domed chamber that possessed nothing but a spiral staircase leading upward. The walls were made of thick glass, and behind it was the dense network you find below every forest. Roots interlocking like fingers, with gossamer fungus sprawled symbiotically between, allowing for the peaceful exchange of carbon and nutrients. Worms traversed roads of their own making. Pockets of water and pebbles decorated the scene. This is what a forest is, after all. Don’t believe the lie of individual trees, each a monument to its own self-made success. A forest is an interdependent community. Resources are shared, and life in isolation is a death sentence. As I stood contemplating the roots, a hidden timer triggered, and the lights faded out. My breath went with it. The glass was etched with some kind of luminescent colourant, invisible when the lights were on, but glowing boldly in the dark. I moved closer, and I saw names – thousands upon thousands of names, printed as small as possible. I understood what I was seeing without being told. The idea behind Open Cluster Astronautics was simple: citizen-funded spaceflight. Exploration for exploration’s sake. Apolitical, international, non-profit. Donations accepted from anyone, with no kickbacks or concessions or promises of anything beyond a fervent attempt to bring astronauts back from extinction. It began in a post thread kicked off in 2052, a literal moonshot by a collective of frustrated friends from all corners – former thinkers for big names gone bankrupt, starry-eyed academics who wanted to do more than teach the past, government bureau members whose governments no longer existed. If you want to do good science with clean money and clean hands, they argued, if you want to keep the fire burning even as flags and logos came down, if you understand that space exploration is best when it’s done in the name of the people, then the people are the ones who have to make it happen.

Out of that global audience, four hundred thousand NASA employees, contractors, and military support watched with particular interest, seeing in the craft that approached the Moon the measure of a screw, the blueprint of a hatch, the filament in a circuit, the fulfillment of a promise made by a president who hadn’t lived to see it carried out. They dotted the globe, those who had worked on Project Apollo, those who had made possible the day that had come. They clustered around displays and switchboards and dials and computers, monitoring every heartbeat of the spacecraft that had slipped out of the influence of its home planet and was now being enticed by the gravitational pull of the Moon. Most of them joined their friends and families in gathering around the televisions as well.

The rover crested a nearby dune with the trailer in tow. It slowed for a few moments, then continued toward the ship at top speed. It came to a stop twenty meters away. There it remained for ten minutes while the astronaut inside suited up. He stumbled excitedly out of the airlock, falling to the ground then scrambling to his feet. Beholding the MAV, he gestured to it with both arms, as if in disbelief. He leaped into the air several times, arms held high with fists clenched. Then he knelt on one knee and fist-pumped repeatedly. Running to the spacecraft, he hugged Landing Strut B. After a few moments, he broke off the embrace to perform another round of leaping celebrations. Now fatigued, the astronaut stood with arms akimbo, looking up at the sleek lines of the engineering marvel before him.

AN INCOMPLETE LIST: No more diving into pools of chlorinated water lit green from below. No more ball games played out under floodlights. No more porch lights with moths fluttering on summer nights. No more trains running under the surface of cities on the dazzling power of the electric third rail. No more cities. No more films, except rarely, except with a generator drowning out half the dialogue, and only then for the first little while until the fuel for the generators ran out, because automobile gas goes stale after two or three years. Aviation gas lasts longer, but it was difficult to come by. No more screens shining in the half-light as people raise their phones above the crowd to take photographs of concert stages. No more concert stages lit by candy-colored halogens, no more electronica, punk, electric guitars. No more pharmaceuticals. No more certainty of surviving a scratch on one’s hand, a cut on a finger while chopping vegetables for dinner, a dog bite. No more flight. No more towns glimpsed from the sky through airplane windows, points of glimmering light; no more looking down from thirty thousand feet and imagining the lives lit up by those lights at that moment. No more airplanes, no more requests to put your tray table in its upright and locked position—but no, this wasn’t true, there were still airplanes here and there. They stood dormant on runways and in hangars. They collected snow on their wings. In the cold months, they were ideal for food storage. In summer the ones near orchards were filled with trays of fruit that dehydrated in the heat. Teenagers snuck into them to have sex. Rust blossomed and streaked. No more countries, all borders unmanned. No more fire departments, no more police. No more road maintenance or garbage pickup. No more spacecraft rising up from Cape Canaveral, from the Baikonur Cosmodrome, from Vandenburg, Plesetsk, Tanegashima, burning paths through the atmosphere into space. No more Internet. No more social media, no more scrolling through litanies of dreams and nervous hopes and photographs of lunches, cries for help and expressions of contentment and relationship-status updates with heart icons whole or broken, plans to meet up later, pleas, complaints, desires, pictures of babies dressed as bears or peppers for Halloween. No more reading and commenting on the lives of others, and in so doing, feeling slightly less alone in the room. No more avatars.

Standing on the left side of the runway was my battle-worn X-wing fighter. Parked on the right side was my DeLorean. Sitting on the runway itself was my most frequently used spacecraft, the Vonnegut. Max had already powered up the engines, and they emitted a low, steady roar that filled the hangar. The Vonnegut was a heavily modified Firefly-class transport vessel, modeled after the Serenity in the classic Firefly TV series. The ship had been named the Kaylee when I’d first obtained it, but I’d immediately rechristened it after one of my favorite twentieth-century novelists. Its new name was stenciled on the side of its battered gray hull. I’d looted the Vonnegut from a cadre of Oviraptor clansmen who had foolishly attempted to hijack my X-wing while I was cruising through a large group of worlds in Sector Eleven known as the Whedonverse. The

Silverstein, one of those leading the charge toward more far-ranging flights than Mercury, had been looking for a suitable name for a payload for the Saturn rockets. None suggested by his associates seemed appropriate. One day, while consulting a book on mythology, Silverstein found what he wanted. He later said, “I thought the image of the god Apollo riding his chariot across the sun gave the best representation of the grand scale of the proposed program.” Occasionally he asked his Headquarters colleagues for their opinions. When no one objected, the chariot driver Apollo (according to ancient Greek myths, the god of music, prophecy, medicine, light, and progress became the name of the proposed circumlunar spaceships. At the opening of the conference on 28 July 1960, Dryden announced that “the next spacecraft beyond Mercury will be called Apollo.

Had your spacecraft flown by the Earth a hundred million years ago, in the age of the dinosaurs when there were no humans and no technology, you would still have seen oxygen and ozone, the chlorophyll pigment, and far too much methane. At present, though, your instruments are finding signs not just of life, but of high technology—something that couldn’t possibly have been detected even a hundred years ago: You are detecting a particular kind of radio wave emanating from Earth. Radio waves don’t necessarily signify life and intelligence. Many natural processes generate them. You’ve already found radio emissions from other, apparently uninhabited worlds—generated by electrons trapped in the strong magnetic fields of planets, by chaotic motions at the shock front that separates these magnetic fields from the interplanetary magnetic field, and by lightning.

We blasted out of the crater and rocketed around the moon’s opposite side, and the fragile Earth became visible to us once again, hovering in the blackness ahead. Over the comm channel, I heard my father gasp at the sight—one he hadn’t seen with his own eyes in an entire lifetime. My lifetime. “There it is,” he said softly. “Home sweet home. Man, I really missed it.” I’d missed it, too, I realized. And I’d been gone less than a day. As our five ships moved into formation and turned homeward, toward Earth, I checked my scope and saw that the three unmanned Interceptors were heading in the opposite direction, out into space, toward whatever destination my father had programmed into them. I turned my gaze back to Earth and watched it begin to grow in size as we approached, until its blue curve completely filled the view outside of my spacecraft. My father sent a tactical map to the display screens inside our cockpits. “They’re dividing their forces in half again,” my father said over the comm. “See?

There was a vague feeling within the agency (though with several notable exceptions) that direct ascent would eventually be the answer, but no one had worked out the tradeoffs in much detail. Subsequently, as Apollo planning progressed, the question of how to fly to the moon and back loomed ever larger. In the end, the choice of mode was perhaps the single greatest technical decision of the entire Apollo program. The selection was inextricably linked to launch vehicles, spacecraft, facilities, cost, development schedules, and the future of America’s posture in space. Ultimately, the mode question shaped the whole of Apollo. Many possible methods were carefully considered, and a Pandora’s box of problems was opened. At the time, however, technical thinking had not matured to that degree. The United States was just on the threshold of manned space flight, and orbital flights around the earth were in themselves mind-boggling. A program to land men on the moon, 400,000 kilometers away, and bring them safely home was nearly too stupendous for serious contemplation.

The “pale blue dot” image and Carl’s prose meditation on it have been beloved the world over ever since. It exemplifies just the kind of breakthrough that I think of as a fulfillment of Einstein’s hope for science. We have gotten clever enough to dispatch a spacecraft four billion miles away and command it to send us back an image of Earth. Seeing our world as a single pixel in the immense darkness is in itself a statement about our true circumstances in the cosmos, and one that every single human can grasp instantly. No advanced degree required. In that photo, the inner meaning of four centuries of astronomical research is suddenly available to all of us at a glance. It is scientific data and art equally, because it has the power to reach into our souls and alter our consciousness. It is like a great book or movie, or any major work of art. It can pierce our denial and allow us to feel something of reality—even a reality that some of us have long resisted. A world that tiny cannot possibly be the center of a cosmos of all that is, let alone the sole focus of its creator. The pale blue dot is a silent rebuke to the fundamentalist, the nationalist, the militarist, the polluter—to anyone who does not put above all other things the protection of our little planet and the life that it sustains in the vast cold darkness. There is no running away from the inner meaning of this scientific achievement.

Discovery first flew in 1984, the third orbiter to join the fleet. It was named for one of the ships commanded by Captain James Cook. Space shuttle Discovery is the most-flown orbiter; today will be its thirty-ninth and final launch. By the end of this mission, it will have flown a total of 365 days in space, making it the most well traveled spacecraft in history. Discovery was the first orbiter to carry a Russian cosmonaut and the first to visit the Russian space station Mir. On that flight, in 1995, Eileen Collins became the first woman to pilot an American spacecraft. Discovery flew twelve of the thirty-eight missions to assemble the International Space Station, and it was responsible for deploying the Hubble Space Telescope in 1990. This was perhaps the most far reaching accomplishment of the shuttle program, as Hubble has been called the most important telescope in history and one of the most significant scientific instruments ever invented. It has allowed astronomers to determine the age of the universe, postulate how galaxies form, and confirm the existence of dark energy, among many other discoveries. Astronomers and astrophysicists, when they are asked about the significance of Hubble, will simply say that it has rewritten the astronomy books. In the retirement process, Discovery will be the “vehicle of record,” being kept as intact as possible for future study. Discovery was the return-to-flight orbiter after the loss of Challenger and then again after the loss of Columbia. To me, this gives it a certain feeling of bravery and hope. ‘Don’t worry,’ Discovery seemed to tell us by gamely rolling her snow-white self out to the launchpad. 'Don’t worry, we can still dream of space. We can still leave the earth.’ And then she did.

Space is nearly empty. There is virtually no chance that one of the Voyagers will ever enter another solar system—and this is true even if every star in the sky is accompanied by planets. The instructions on the record jackets, written in what we believe to be readily comprehensible scientific hieroglyphics, can be read, and the contents of the records understood, only if alien beings, somewhere in the remote future, find Voyager in the depths of interstellar space. Since both Voyagers will circle the center of the Milky Way Galaxy essentially forever, there is plenty of time for the records to be found—if there's anyone out there to do the finding. We cannot know how much of the records they would understand. Surely the greetings will be incomprehensible, but their intent may not be. (We thought it would be impolite not to say hello.) The hypothetical aliens are bound to be very different from us—independently evolved on another world. Are we really sure they could understand anything at all of our message? Every time I feel these concerns stirring, though, I reassure myself. Whatever the incomprehensibilities of the Voyager record, any alien ship that finds it will have another standard by which to judge us. Each Voyager is itself a message. In their exploratory intent, in the lofty ambition of their objectives, in their utter lack of intent to do harm, and in the brilliance of their design and performance, these robots speak eloquently for us. But being much more advanced scientists and engineers than we—otherwise they would never be able to find and retrieve the small, silent spacecraft in interstellar space—perhaps the aliens would have no difficulty understanding what is encoded on these golden records. Perhaps they would recognize the tentativeness of our society, the mismatch between our technology and our wisdom. Have we destroyed ourselves since launching Voyager, they might wonder, or have we gone on to greater things? Or perhaps the records will never be intercepted. Perhaps no one in five billion years will ever come upon them. Five billion years is a long time. In five billion years, all humans will have become extinct or evolved into other beings, none of our artifacts will have survived on Earth, the continents will have become unrecognizably altered or destroyed, and the evolution of the Sun will have burned the Earth to a crisp or reduced it to a whirl of atoms. Far from home, untouched by these remote events, the Voyagers, bearing the memories of a world that is no more, will fly on.

Similarly, the computers used to run the software on the ground for the mission were borrowed from a previous mission. These machines were so out of date that Bowman had to shop on eBay to find replacement parts to get the machines working. As systems have gone obsolete, JPL no longer uses the software, but Bowman told me that the people on her team continue to use software built by JPL in the 1990s, because they are familiar with it. She said, “Instead of upgrading to the next thing we decided that it was working just fine for us and we would stay on the platform.” They have developed so much over such a long period of time with the old software that they don’t want to switch to a newer system. They must adapt to using these outdated systems for the latest scientific work. Working within these constraints may seem limiting. However, building tools with specific constraints—from outdated technologies and low bitrate radio antennas—can enlighten us. For example, as scientists started to explore what they could learn from the wait times while communicating with deep space probes, they discovered that the time lag was extraordinarily useful information. Wait times, they realized, constitute an essential component for locating a probe in space, calculating its trajectory, and accurately locating a target like Pluto in space. There is no GPS for spacecraft (they aren’t on the globe, after all), so scientists had to find a way to locate the spacecraft in the vast expanse. Before 1960, the location of planets and objects in deep space was established through astronomical observation, placing an object like Pluto against a background of stars to determine its position.15 In 1961, an experiment at the Goldstone Deep Space Communications Complex in California used radar to more accurately define an “astronomical unit” and help measure distances in space much more accurately.16 NASA used this new data as part of creating the trajectories for missions in the following years. Using the data from radio signals across a wide range of missions over the decades, the Deep Space Network maintained an ongoing database that helped further refine the definition of an astronomical unit—a kind of longitudinal study of space distances that now allows missions like New Horizons to create accurate flight trajectories. The Deep Space Network continued to find inventive ways of using the time lag of radio waves to locate objects in space, ultimately finding that certain ways of waiting for a downlink signal from the spacecraft were less accurate than others. It turned to using the antennas from multiple locations, such as Goldstone in California and the antennas in Canberra, Australia, or Madrid, Spain, to time how long the signal took to hit these different locations on Earth. The time it takes to receive these signals from the spacecraft works as a way to locate the probes as they are journeying to their destination. Latency—or the different time lag of receiving radio signals on different locations of Earth—is the key way that deep space objects are located as they journey through space. This discovery was made possible during the wait times for communicating with these craft alongside the decades of data gathered from each space mission. Without the constraint of waiting, the notion of using time as a locating feature wouldn’t have been possible.

All the many successes and extraordinary accomplishments of the Gemini still left NASA’s leadership in a quandary. The question voiced in various expressions cut to the heart of the problem: “How can we send men to the moon, no matter how well they fly their ships, if they’re pretty helpless when they get there? We’ve racked up rendezvous, docking, double-teaming the spacecraft, starting, stopping, and restarting engines; we’ve done all that. But these guys simply cannot work outside their ships without exhausting themselves and risking both their lives and their mission. We’ve got to come up with a solution, and quick!” One manned Gemini mission remained on the flight schedule. Veteran Jim Lovell would command the Gemini 12, and his space-walking pilot would be Buzz Aldrin, who built on the experience of the others to address all problems with incredible depth and finesse. He took along with him on his mission special devices like a wrist tether and a tether constructed in the same fashion as one that window washers use to keep from falling off ledges. The ruby slippers of Dorothy of Oz couldn’t compare with the “golden slippers” Aldrin wore in space—foot restraints, resembling wooden Dutch shoes, that he could bolt to a work station in the Gemini equipment bay. One of his neatest tricks was to bring along portable handholds he could slap onto either the Gemini or the Agena to keep his body under control. A variety of space tools went into his pressure suit to go along with him once he exited the cabin. On November 11, 1966, the Gemini 12, the last of its breed, left earth and captured its Agena quarry. Then Buzz Aldrin, once and for all, banished the gremlins of spacewalking. He proved so much a master at it that he seemed more to be taking a leisurely stroll through space than attacking the problems that had frustrated, endangered, and maddened three previous astronauts and brought grave doubts to NASA leadership about the possible success of the manned lunar program. Aldrin moved down the nose of the Gemini to the Agena like a weightless swimmer, working his way almost effortlessly along a six-foot rail he had locked into place once he was outside. Next came looping the end of a hundred-foot line from the Agena to the Gemini for a later experiment, the job that had left Dick Gordon in a sweatbox of exhaustion. Aldrin didn’t show even a hint of heavy breathing, perspiration, or an increased heartbeat. When he spoke, his voice was crisp, sharp, clear. What he did seemed incredibly easy, but it was the direct result of his incisive study of the problems and the equipment he’d brought from earth. He also made sure to move in carefully timed periods, resting between major tasks, and keeping his physical exertion to a minimum. When he reached the workstation in the rear of the Gemini, he mounted his feet and secured his body to the ship with the waist tether. He hooked different equipment to the ship, dismounted other equipment, shifted them about, and reattached them. He used a unique “space wrench” to loosen and tighten bolts with effortless skill. He snipped wires, reconnected wires, and connected a series of tubes. Mission Control hung on every word exchanged between the two astronauts high above earth. “Buzz, how do those slippers work?” Aldrin’s enthusiastic voice came back like music. “They’re great. Great! I don’t have any trouble positioning my body at all.” And so it went, a monumental achievement right at the end of the Gemini program. Project planners had reached all the way to the last inch with one crucial problem still unsolved, and the man named Aldrin had whipped it in spectacular fashion on the final flight. Project Gemini was

a paradox that Elon is working to improve our planet at the same time he’s building spacecraft to help us leave it.

It’s called the flyby anomaly, because there are multiple instances where NASA’s Galileo, NEAR, Pioneer 10, and Pioneer 11 spacecraft have experienced an unexplainable increase in speed over massive distances. It’s always when they’re passing Earth at enough of a distance to not be affected by its gravitational pull, yet they somehow pick up speed, like a universal force is inside stepping on the accelerator.

Collin shrugged, which he immediately regretted. Teenagers shrug. Spacecraft captains do or say something cool.

Inertia propulsion!” Pierre exclaimed. “On our last shift we were teaching them Newton’s law of gravity. Today they have inertia drives! Where will they be tomorrow?” “They probably will be able to control space and time and won’t have to bother with such clumsy things as black hole gravity generators and inertia drives,” Amalita replied. “But now I see why we were so awkward. Their main spacecraft will stay fifteen meters away from our spacecraft, but it is so massive that we will experience about one-third of a gee from it, pulling me out of the console chair and over to the viewing port. I guess I could manage to twirl once as I fall so they can see the human joints in action, but I bet I am going to be clumsier in one-third gee than that animation.” She turned from the screen and looked at him, “I wish you were doing my part, so I could get to see the cheela.” “I don’t know whether you would like it,” Pierre said. “According to this contour plot of the gravity field from the individual craft, although the size and mass of the flitters are much smaller than the main spacecraft, this one is going to come up to less than one meter from my viewing port and my nose is going to be pulling three gees!” He looked down at her body and grinned, “I guess the reason they didn’t choose you is they must know you don’t wear a bra in free-fall and they didn’t want to give you reverse Cooper’s droop.” Amalita turned back to the display, jabbing him with her elbow as she did so, and brought up the next screen full of instructions.

Anyway, I was talking about the cold spots.  Those’re the places where you’re inside the fissure.” “Fissure?” “Yeah.  Like a crack between worlds.” “Worlds?  What, like a wormhole?”  Again, he thought of aliens and extra-terrestrial spacecraft.  “No.  You’re thinking of planets.  I said worlds.  Dimensions, if you prefer.” “Like parallel realities?” “Sort of.  Yeah.  There’s our world, the one we know, and then there’s this other one.  Scary-ass place, apparently.  I think it’s where those things in the barn came from.

CHAPTER ONE Introduction to Digital Compositing A massive spacecraft hovers over New York, throwing the entire city into shadow. A pair of lizards, sitting in the middle of a swamp, discuss their favorite beer. Dinosaurs, long extinct, live and breathe

Stuster found that careful attention to habitat design and crew compatibility could avoid psychological and interpersonal problems. He called for windows in spacecraft, noting studies of submarine crewmen who developed temporarily crossed eyes on long missions.

This country has a UFO problem, after all. You might not have been aware we have one, or thought about it in these terms, but we do have a UFO problem: namely, we don't seem to understand what UFO really means. So here it is: a UFO is an unidentified flying object. So any time we see some object flying in the sky that we can't positively identify, we've seen a UFO. But in the same way the words paranormal and supernatural have been conflated, we now equate UFO with alien spacecraft. How this came to be is easily understandable. If we've learned one thing in this book already, people don't like the unknown very much. And so, if we believe we're being visited by other civilizations, we read the piles of books and articles on unexplained lights in the sky, then fill in the massive gaps—with wild tales of alien races, interstellar technology, and government conspiracies. If we don't believe, we hear someone saw an unexplained light in the sky and assume, first, that he's claiming to have seen E.T. Then we figure what he really saw was an airplane, Venus, swamp gas, or a helicopter, and he must be a bit foolish—maybe even a UFO nut. Then we laugh.

Earth’s axis wobbles constantly as we hurtle around the sun at about 66,000 miles per hour and the sun moves around the center of the galaxy at about 500,000 miles per hour.
