Jupiter's Travels Quotes

In the twentieth century, astrophysicists in the United States discovered galaxies, the expanding of the universe, the nature of supernovas, quasars, black holes, gamma-ray bursts, the origin of the elements, the cosmic microwave background, and most of the known planets in orbit around solar systems other than our own. Although the Russians reached one or two places before us, we sent space probes to Mercury, Venus, Jupiter, Saturn, Uranus, and Neptune. American probes have also landed on Mars and on the asteroid Eros. And American astronauts have walked on the Moon. Nowadays most Americans take all this for granted, which is practically a working definition of culture: something everyone does or knows about, but no longer actively notices. While shopping at the supermarket, most Americans aren’t surprised to find an entire aisle filled with sugar-loaded, ready-to-eat breakfast cereals. But foreigners notice this kind of thing immediately, just as traveling Americans notice that supermarkets in Italy display vast selections of pasta and that markets in China and Japan offer an astonishing variety of rice. The flip side of not noticing your own culture is one of the great pleasures of foreign travel: realizing what you hadn’t noticed about your own country, and noticing what the people of other countries no longer realize about themselves.

In the seventeenth and eighteenth centuries you could travel from Holland to China in a year or two, the time it has taken Voyager to travel from Earth to Jupiter.

Imagine you are Siri Keeton: You wake in an agony of resurrection, gasping after a record-shattering bout of sleep apnea spanning one hundred forty days. You can feel your blood, syrupy with dobutamine and leuenkephalin, forcing its way through arteries shriveled by months on standby. The body inflates in painful increments: blood vessels dilate; flesh peels apart from flesh; ribs crack in your ears with sudden unaccustomed flexion. Your joints have seized up through disuse. You're a stick-man, frozen in some perverse rigor vitae. You'd scream if you had the breath. Vampires did this all the time, you remember. It was normal for them, it was their own unique take on resource conservation. They could have taught your kind a few things about restraint, if that absurd aversion to right-angles hadn't done them in at the dawn of civilization. Maybe they still can. They're back now, after all— raised from the grave with the voodoo of paleogenetics, stitched together from junk genes and fossil marrow steeped in the blood of sociopaths and high-functioning autistics. One of them commands this very mission. A handful of his genes live on in your own body so it too can rise from the dead, here at the edge of interstellar space. Nobody gets past Jupiter without becoming part vampire.

Maybe you know how it is when you have decided to do something really enormous with your life, something that stretches your resources to the limit. You can get the feeling that you are engaged in a trial of strength with the universe.

In spite of wars and tourism and pictures by satellite, the world is just the same size it ever was. It is awesome to think how much of it I will never see. It is not a trick to go round these days, you can pay a lot of money and fly round it nonstop in less than forty-eight hours, but to know it, to smell it and feel it between your toes you have to crawl. There is no other way. Not flying, not floating. You have to stay on the ground and swallow the bugs as you go. Then the world is immense. The best you can do is to trace your long, infinitesimally thin line through the dust and extrapolate.

There needs to be an intersection of the set of people who wish to go, and the set of people who can afford to go...and that intersection of sets has to be enough to establish a self-sustaining civilisation. My rough guess is that for a half-million dollars, there are enough people that could afford to go and would want to go. But it’s not going to be a vacation jaunt. It’s going to be saving up all your money and selling all your stuff, like when people moved to the early American colonies...even at a million people you’re assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil.Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we’re talking 100,000 trips of a giant spaceship...If we can establish a Mars colony, we can almost certainly colonise the whole Solar System, because we’ll have created a strong economic forcing function for the improvement of space travel. We’ll go to the moons of Jupiter, at least some of the outer ones for sure, and probably Titan on Saturn, and the asteroids. Once we have that forcing function, and an Earth-to-Mars economy, we’ll cover the whole Solar System. But the key is that we have to make the Mars thing work. If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation. That’s the next step.

The gods would never allow such a perverse outcome, would they? I am divine. My place is on the mountaintop with Jupiter, Mars and Apollo.

Terraforming Mars is a primary goal for the twenty-second century. But scientists are looking beyond Mars as well. The most exciting prospects may be the moons of the gas giants, including Europa, a moon of Jupiter, and Titan, a moon of Saturn. The moons of gas giants were once thought to be barren hunks of rock that were all alike, but they are now seen as unique wonderlands, each with its own array of geysers, oceans, canyons, and atmospheric lights. These moons are now being eyed as future habitats for human life.

First, to create the violent distortions of space and time necessary to travel through a wormhole, one would need fabulous amounts of positive and negative matter, on the order of a huge star or a black hole. Matthew Visser, a physicist at Washington University, estimates that the amount of negative energy you would need to open up a 1-meter wormhole is comparable to the mass of Jupiter, except that it would need to be negative. He says, "You need about minus one Jupiter mass to do the job. Just manipulating a positive Jupiter mass of energy is already pretty freaky, well beyond our capabilities into the foreseeable future.

Newton's laws specifically state that, while the gravity of a planet gets weaker and weaker the farthest from it you travel, there is no distance where the force of gravity reaches zero. The planet Jupiter, with its mighty gravitational field, bats out of harm's way many comets that would otherwise wreak havoc on the inner solar system. Jupiter acts as a gravitational shield for Earth, a burly big brother, allowing long (hundred-million-year) stretches of relative peace and quiet on Earth. Without Jupiter's protection, complex life would have a hard time becoming interestingly complex, always living at risk of extinction from a devastating impact.

Physicists then tried to calculate the amount of negative matter or energy necessary to propel a starship. The latest results indicate that the amount required is equivalent to the mass of the planet Jupiter. This means that only a very advanced civilization will be able to use negative matter or energy to propel their starships, if it is possible at all. (However, it is possible that the amount of negative matter or energy necessary to go faster than light could drop, because the calculations depend on the geometry and size of the warp bubble or wormhole.) Star Trek gets around this inconvenient hurdle by postulating that a rare mineral called the dilithium crystal is the essential component of a warp drive engine. Now we know that "dilithium crystals" may be a fancy way of saying "negative matter or energy.

What else can you do with the law of gravitation? If we look at the moons of Jupiter we can understand everything about the way they move around that planet. Incidentally, there was once a certain difficulty with the moons of Jupiter that is worth remarking on. These satellites were studied very carefully by Rømer, who noticed that the moons sometimes seemed to be ahead of schedule, and sometimes behind. (One can find their schedules by waiting a very long time and finding out how long it takes on the average for the moons to go around.) Now they were ahead when Jupiter was particularly close to the earth and they were behind when Jupiter was farther from the earth. This would have been a very difficult thing to explain according to the law of gravitation—it would have been, in fact, the death of this wonderful theory if there were no other explanation. If a law does not work even in one place where it ought to, it is just wrong. But the reason for this discrepancy was very simple and beautiful: it takes a little while to see the moons of Jupiter because of the time it takes light to travel from Jupiter to the earth. When Jupiter is closer to the earth the time is a little less, and when it is farther from the earth, the time is more. This is why moons appear to be, on the average, a little ahead or a little behind, depending on whether they are closer to or farther from the earth. This phenomenon showed that light does not travel instantaneously, and furnished the first estimate of the speed of light. This was done in 1676.

For three days and two nights I drift up the Nile along Lake Nasser. The sunrises and sunsets are so extraordinarily beautiful that my body turns inside out and empties my heart into the sky. The stars are close enough to grasp. Lying on the roof of the ferry at night, I begin at last to know the constellations, and start a personal relationship with that particular little cluster of jewels called the Pleiades, which nestles in the sky not far from Orion's belt and sword. Really, those stars, when they come that close, you have to take them seriously.

To The Undertaker or Friends Who Open This Coffin: After laying back the lid of the coffin, remove entirely the pads from the sides of the face, as they are intended merely to steady the head in traveling. If there be any discharge of liquid from the eyes, nose, or mouth, which often occurs from the constant shaking of the cars, wipe it off gently with a soft piece of cotton cloth, slightly moistened. This body was received by us for embalmment in a ____________ condition and the natural condition is ____________ preserved. Embalming was/was not possible. After removing the coffin lid, leave it off for some time and let the body have the air. Dr. Jupiter Jones, Embalmer & Keeper of the Dead

There are only two types of waves that can travel across the universe bringing us information about things far away: electromagnetic waves (which include light, X-rays, gamma rays, microwaves, radio waves…); and gravitational waves. Electromagnetic waves consist of oscillating electric and magnetic forces that travel at light speed. When they impinge on charged particles, such as the electrons in a radio or TV antenna, they shake the particles back and forth, depositing in the particles the information the waves carry. That information can then be amplified and fed into a loudspeaker or on to a TV screen for humans to comprehend. Gravitational waves, according to Einstein, consist of an oscillatory space warp: an oscillating stretch and squeeze of space. In 1972 Rainer (Rai) Weiss at the Massachusetts Institute of Technology had invented a gravitational-wave detector, in which mirrors hanging inside the corner and ends of an L-shaped vacuum pipe are pushed apart along one leg of the L by the stretch of space, and pushed together along the other leg by the squeeze of space. Rai proposed using laser beams to measure the oscillating pattern of this stretch and squeeze. The laser light could extract a gravitational wave’s information, and the signal could then be amplified and fed into a computer for human comprehension. The study of the universe with electromagnetic telescopes (electromagnetic astronomy) was initiated by Galileo, when he built a small optical telescope, pointed it at Jupiter and discovered Jupiter’s four largest moons. During the 400 years since then, electromagnetic astronomy has completely revolutionised our understanding of the universe.

It was also a lot easier for online teachers to hold their students’ attention, because here in the OASIS, the classrooms were like holodecks. Teachers could take their students on a virtual field trip every day, without ever leaving the school grounds. During our World History lesson that morning, Mr. Avenovich loaded up a stand-alone simulation so that our class could witness the discovery of King Tut’s tomb by archaeologists in Egypt in AD 1922. (The day before, we’d visited the same spot in 1334 BC and had seen Tutankhamun’s empire in all its glory.) In my next class, Biology, we traveled through a human heart and watched it pumping from the inside, just like in that old movie Fantastic Voyage. In Art class we toured the Louvre while all of our avatars wore silly berets. In my Astronomy class we visited each of Jupiter’s moons. We stood on the volcanic surface of Io while our teacher explained how the moon had originally formed. As our teacher spoke to us, Jupiter loomed behind her, filling half the sky, its Great Red Spot churning slowly just over her left shoulder. Then she snapped her fingers and we were standing on Europa, discussing the possibility of extraterrestrial life beneath the moon’s icy crust.

Briefcase Crunch time. To escape the gravity of Jupiter, a spacecraft would have to travel over 134,000 miles per hour! Compare that to how fast space shuttles have to travel to clear the earth’s gravity–seven miles a second, or about 25,000 miles per hour. Get too close to Jupiter, and you’re not coming back! People are made for gravity. Astronauts in space have a great time floating around without gravity. But weightlessness eventually does bad things to bones and blood. Space experiments on rats in spinning cages (kind of like the centrifuge in our story, only not as dizzying) showed animals that got just a little gravity in space came back much healthier. Even before the Internet, people in Bible times had a pretty good idea of who set up the earth and the stars. Check out this psalm, written by King David nearly one thousand years before Jesus was born: “I think about the heavens. I think about what your fingers have created. I think about the moon and stars that you have set in place. What is a human being that you think about him? What is a son of man that you take care of him?” (Psalm 8:3 - 4).

There's a lot of water everywhere. The roads near the sea front are under two feet of it. Do they mention this in the brochures? I see a package of Nordic tourists washed up in a hotel lobby. The hotel looks as though it has absorbed its own weight of water.

Instant information is instantly obsolete. Only the most banal ideas can successfully cross great distances at the speed of light. And anything that travels very far very fast is scarcely worth transporting, especially the tourist.

Oh tell me please, how does it go, the triple jump?" She pro nounced it tripee-el She had a way of pleading for things in her Brazilian English to make you understand that they were matters simultaneously of no consequence and of life and death. You could refuse, and nothing would be changed; or you could give, and earn undying gratitude. It was a great gift, which she had won by long effort and sorrow and laughter. It was the humorous residue of cravings which had once been corrosive enough to etch her face. "Is that the hop, skip and jump?" I asked lazily from the rock where I was sitting and reading. I did not want to leave my rock. I had my left leg over the side with the foot in the sand. Every thirty seconds or so the movements of the water combined to send a wave swishing along the side of the rock, covering my leg up to the knee and cooling it. I felt the sun's heat flowing through me into the sea. "I really don't know," I said. `Why? What's fascinating you?" She had asked about the triple jump once before, I remembered, in Rio. "I don't know," she said, each word long-drawn-out and husky. "I am going to try it anyway." She pursed her mouth and did a coltish sprint along the sand finishing with both feet together. She stood for a while with the sun on her back, her face in shadow, looking again at the prints she had left. I watched her still, exploring the shape of her body. I would have expected a dancer's body to be harder, to show more muscle.

Future destinations in our solar system neighborhood include potential probe missions to a few moons of Jupiter, Saturn, and Neptune -- mainly by virtue of them being possible candidates for life, with their large oceans buried beneath icy crusts, plus intense volcanic activity. But getting humans to explore these possibly habitable worlds is a big issue in space travel. The record for the fastest-ever human spaceflight was set by the Apollo 10 crew as they gravita­tionally slingshotted around the Moon on their way back to Earth in May 1969. They hit a top speed of 39,897 kilo­meters per hour (24,791 miles per hour); at that speed you could make it from New York to Sydney and back in under one hour. Although that sounds fast, we've since recorded un-crewed space probes reaching much higher speeds, with the crown currently held by NASA's Juno probe, which, when it entered orbit around Jupiter, was traveling at 266,000 kilometers per hour (165,000 miles per hour). To put this into perspective, it took the Apollo 10 mission four days to reach the Moon; Opportunity took eight months to get to Mars; and Juno took five years to reach Jupiter. The distances in our solar system with our current spaceflight technology make planning for long-term crewed explora­tion missions extremely difficult." "So, will we ever explore beyond the edge of the solar system itself? The NASA Voyager 1 and 2 spacecraft were launched back in 1977 with extended flyby missions to the outer gas giant planets of Jupiter and Saturn. Voyager 2 even had flyby encounters with Uranus and Neptune -- it's the only probe ever to have visited these two planets. "The detailed images you see of Uranus and Neptune were all taken by Voyager 2. Its final flyby of Neptune was in October 1989, and since then, it has been traveling ever farther from the Sun, to the far reaches of the solar sys­tem, communicating the properties of the space around it with Earth the entire time. In February 2019, Voyager 2 reported a massive drop off in the number of solar wind particles it was detecting and a huge jump in cosmic ray particles from outer space. At that point, it had finally left the solar system, forty-one years and five months after being launched from Earth. "Voyager 1 was the first craft to leave the solar system in August 2012, and it is now the most distant synthetic object from Earth at roughly 21.5 billion kilometers (13.5 billion miles) away. Voyager 2 is ever so slightly closer to us at 18 billion kilometers (11 billion miles) away. Although we may ultimately lose contact with the Voyager probes, they will continue to move ever farther away from the Sun with nothing to slow them down or impede them. For this reason, both Voyager crafts carry a recording of sounds from Earth, including greetings in fifty-five differ­ent languages, music styles from around the world, and sounds from nature -- just in case intelligent life forms happen upon the probes in the far distant future when the future of humanity is unknown.

Everything in this picture I took with me, except the tires. They were sent on. And the umbrella? That was the photographer's, but eventually I did get one of my own, and it was remarkably useful. I strapped it alongside, under the saddle and over a box on my right. On the left side I carried a sword, but that's another story...

My appointment with destiny was approaching. Raj's father was getting ready to leave for his office in Patna. "Come," he said. "We'll sit in the car." We sat turned towards each other, and he said: "Give me your hand." I held it out, and he grasped it as in a handshake, but held it in his grip for several moments. Then, releasing it, he gave my thumb a quick backward flip, and murmured: "Achcha! "You have a very determined soul. This also is reflected in your mind. "You are Jupiter...." Why not? I thought. I like the sound of that.

If the Japanese ever got a foothold, British bikes would quickly become only a nostalgic memory.

But it was nothing, a paper seal slipped in assembly, easily put right. You could stop the oil if you took the trouble. That was what British bikes liked, a bit of trouble. They thrived on attention, like certain people, and repaid you for it. Not a bad relationship to have.

What happened on the way, who I met, all that was incidental. I had not quite realized that the interruptions were the journey.

The enigma that had bothered me in Sydney was beginning to resolve itself. If Australians allowed themselves to be represented worldwide as a nation of beer-sodden boors and hysterical Amazons, it must be through sheer lack of imagination. Like most people everywhere they spent most of their time just getting by, but there was no collective dream or mythology that told them what it was they were supposed to be doing. In that respect they were far behind the Aborigines they had decimated and despised. Yet many signs indicated that the time might not be too far away, when Australians would agree on a better reason for living than to eat a pound of beef a day. When that day came, I thought this would become one of the world’s best places to be. The faces of the old men told me there had been something once that was lost and could be found again.

We showed Dennis the gully and told him this was a typical old Queensland house with the high tongue-and-groove walls and the ventilation panels over the doors filled with graceful carved vines. He did not look at anything with much interest, but talked about China, where he had just been. X said afterwards that Dennis always talked about the last place he’d been and the last people he’d seen, and never seemed to notice anything, but that he would probably be talking about us, and describing this place, to the next people he had dinner with, in the next city. He said that Dennis spent most of his life travelling, and talking about it, and that he knew a lot of people just well enough that when he showed up somewhere he had to be asked to dinner.

If it weren’t for Jupiter, you can justifiably question whether Earth could have ever made it from simple life to complex life.” ■

Generally when a man in uniform has something unusual brought to his attention, his instinct is to stop it.

Until that morning, her brother Nico had been the most powerful demigod she knew. The others at Camp Jupiter saw him as a traveling oddball, about as harmless as the fauns. Hazel knew better. She hadn't grown up with Nico, hadn't even known him very long. But she knew Nico was more dangerous than Reyna, or Octavian, or maybe even Jason. Then she'd met Percy. At first, when she saw him stumbling up the highway with the old lady in his arms, Hazel had thought he might be a god in disguise. Even though he was beat up, dirty, and stooped with exhaustion, he'd had an aura of power. He had the good looks of a Roman god, with sea-green eyes and wind blown black hair. She'd ordered Frank not to fire on him. She thought the gods might be testing them. She'd heard myths like that: a kid with an old lady begs for shelter, and when the rude mortals refuse-boom, they get turned into banana slugs.

That particular passion which caused me to pursue for years on end a journey that others would scarcely contemplate, that many regarded as an act of folly or arrogance, arose out of my own peculiarity. I saw that it would make me a difficult person to live with, just as I knew that without it I could hardly live with myself.

Like last time, when we walked into a bathroom and surprised a Cyclops on the toilet?’ ‘That wasn’t my fault!’ Grover protested. ‘Besides, this direction smells right. Like … cacti.’ Meg sniffed the air. ‘I don’t smell cacti.’ ‘Meg,’ I said, ‘the satyr is supposed to be our guide. We don’t have much choice but to trust him.’ Grover huffed. ‘Thanks for the vote of confidence. Your daily reminder: I didn’t ask to be magically summoned halfway across the country and wake up in a rooftop tomato patch in Indianapolis!’ Brave words, but he kept his eyes on the twin rings around Meg’s middle fingers, perhaps worried she might summon her golden scimitars and slice him into rotisserie-style cabrito. Ever since learning that Meg was a daughter of Demeter, the goddess of growing things, Grover Underwood had acted more intimidated by her than by me, a former Olympian deity. Life was not fair. Meg wiped her nose. ‘Fine. I just didn’t think we’d be wandering around down here for two days. The new moon is in –’ ‘Three more days,’ I said, cutting her off. ‘We know.’ Perhaps I was too brusque, but I didn’t need a reminder about the other part of the prophecy. While we travelled south to find the next Oracle, our friend Leo Valdez was desperately flying his bronze dragon towards Camp Jupiter, the Roman demigod training ground in Northern California, hoping to warn them about the fire, death and disaster that supposedly faced them at the new moon. I tried to soften my tone. ‘We have to assume Leo and the Romans can handle whatever’s coming in the north. We have our own task.’ ‘And plenty of our own fires.

If Thoreau were alive today he would have full confirmation of his fears. Instant information is instantly obsolete. Only the most banal ideas can successfully cross great distances at the speed of light. And anything that travels very far very fast is scarcely worth transporting, especially the tourist.
