Isn’t antimatter what fuels the U.S.S. Enterprise?

It’s pretty hard to get to another star system. Alpha Centauri is four light years away, so if you go at 10 per cent of the speed of light, it’s going to take you 40 years, and that’s assuming you can instantly reach that speed, which isn’t going to be the case. You have to accelerate. You have to build up to 20 or 30 per cent and then slow down, assuming you want to stay at Alpha Centauri and not go zipping past. It’s just hard. With current life spans, you need generational ships. You need antimatter drives, because that’s the most mass-efficient. It’s doable, but it’s super slow.

I will tell you sincerely and without exaggeration that the best part of lunch today at the NASA Ames cafeteria is the urine. It is clear and sweet, though not in the way mountain streams are said to be clear and sweet. More in the way of Karo syrup. The urine has been desalinated by osmotic pressure. Basically it swapped molecules with a concentrated sugar solution. Urine is a salty substance (though less so than the NASA Ames chili), and if you were to drink it in an effort to rehydrate yourself, it would have the opposite effect. But once the salt is taken care of and the distasteful organic molecules have been trapped in an activated charcoal filter, urine is a restorative and surprisingly drinkable lunchtime beverage. I was about to use the word unobjectionable, but that's not accurate. People object. They object a lot.

Just because your electronics are better than ours, you aren't necessarily superior in any way. Look, imagine that you humans are a man in LA with a brand-new Trujillo and we are a nuhp in New York with a beat-up old Ford. The two fellows start driving toward St. Louis. Now, the guy in the Trujillo is doing 120 on the interstates, and the guy in the Ford is putting along at 55; but the human in the Trujillo stops in Vegas and puts all of his gas money down the hole of a blackjack table, and the determined little nuhp cruises along for days until at last he reaches his goal. It's all a matter of superior intellect and the will to succeed. Your people talk a lot about going to the stars, but you just keep putting your money into other projects, like war and popular music and international athletic events and resurrecting the fashions of previous decades. If you wanted to go into space, you would have.

Mars looks like Vegas without the casinos.

Konstantin Tsiolkovsky in Russia, Hermann Olberth in Germany, and Robert Goddard in the United States all came up with an eerily similar concept for using liquid fuel to power rockets for human spaceflight. I've seen this pointed out as an odd coincidence, one of those moments when an idea inexplicably emerges in multiple places at once. But when I read through each of these three men's biographies I discovered why they all had the same idea: all three of them were obsessed with Jules Verne's 1865 novel "De la terre a la lune (From the Earth to the Moon)." The novel details the strange adventures of three space explorers who travel to the moon together. What sets Verne's book apart from the other speculative fiction of the time was his careful attention to the physics involved in space travel -- his characters take pains to explain to each other exactly how and why each concept would work. All three real-life scientists -- the Russian, the German, and the American -- were following what they had learned from a French science fiction writer.

Most of the people on the Cloud Ark were going to have to be women. There were other reasons for it besides just making more babies. Research on the long-term effects of spaceflight suggested that women were less susceptible to radiation damage than men. They were smaller on average, requiring less space, less food, less air. And sociological studies pointed to the idea that they did better when crammed together in tight spaces for long periods of time. This was controversial, as it got into fraught topics of nature vs. nurture and whether gender identity was a social construct or a genetic program.

Nikki could barely pull herself away from the spinning alien beauty in the window, but Elon Musk was on the big screen with a drink in his hand. “Congratulations, Starship, on entering Martian orbit,” he said, smiling and raising his flute of champagne from the now very distant Florida peninsula. “Cheers to the six of you and best wishes for a safe and stellar landing on Monday.” -- from the upcoming novel MARS COLONY AGATHA: NIKKI RED by Jack Chaucer, 1-1-20

Normal people have rock collections, shell collections, key ring collections and stamp collections. (The Captain had even known somebody with a letterbox collection.) But a people collection? That had to be the most bizarre one he'd come across. Not to mention the most unethical.

One recalls the literary writer who, after grasping a story of a Mars voyage as a metaphor for isolation and the precariousness of relationships, realized that at a deeper, more subtle level it might even be a story about an actual trip to Mars!

No amount of standing on hilltops on dark nights and surveying the heavens could prepare a man for the actuality of space travel, because the earthbound observer saw only the the stars, not what separated them. They glittered in his vision, filling his eyes, and he had no choice but to assign them a position of importance in the cosmic scheme. The space traveler saw things differently. He was made aware that the universe consisted of emptiness, that the suns and nebulae were almost an irrelevancy, that the stars were nothing more than a whiff of gas diffusing into infinity. And sooner or later that knowledge began to hurt.

Only since the collapse of the Soviet Union have we learned that the Soviets were in fact developing a moon rocket, known as the N1, in the sixties. All four launch attempts of the N1 ended in explosions. Saturn was the largest rocket in the world, the most complex and powerful ever to fly, and remains so to this day. The fact that it was developed for a peaceful purpose is an exception to every pattern of history, and this is one of the legacies of Apollo.

People ask what will happen if Mars One fails. There will be Mars Two, Mars Three, there will be Gliese 581 One, Proxima Centauri b One etc. If a project opens the path for other projects, it means that it has already triumphed!

It is a very sobering feeling to be up in space and realize that one's safety factor was determined by the lowest bidder on a government contract.

On this planet are every kind of deadly animal from across the stars. The only people that come here are hunters looking for the most dangerous of trophies. No rescue. You either get your prize or you die.

She and Kennedy both dove for the power connector; Kennedy reached it first and yanked out the connection as Alex landed on her stomach beside it. The air settled down until the fine hairs on her arm no longer stood on end. Alex dropped her forehead to the platform and started laughing. “Just like university, isn’t it?” “Almost—nothing’s actually blown up yet.

Riley asked himself why he had ever considered space travel romantic. “Because you are a romantic,” his pedia said.

She points to where he went and looks to the neutral Baumen. “He—he did that to me on purpose! He’s insane. Literally, insane!” The munchkin just shrugs. “Welcome aboard!” and returns unconcerned to his work.

She skidded around a corner, slamming her shoulder into the wall and bouncing off of it without slowing. Caleb? Silence. Forty-six meters. A long stretch of hallway. She pushed faster, harder. Twenty meters. She burst into the room in unison with a deafening crash of metal shearing metal.

People feared what they did not understand, and they without a doubt did not understand her. Those who believed they did least of all. She was something new.

Smiling now, Michael Dawn sat on his rooftop, gazing at the stars above him, just like men had done for thousands of years. Out there lay secrets and mysteries that an eternity could never unravel, worlds he could only imagine. Yet looking at them then, it all seemed so surreal. As if the only purpose the stars had in this world was to shine their tiny points of light down on him that evening. To give him something beautiful and breathtaking to admire. Maybe that was their only purpose. Maybe trying to get more out of them, trying to travel among them and shed light on things that were better left unexposed, had been the trouble all along.

Soon our culture's oldest dreams will be made real. Even the thought of sending a kind of flying craft to the moon is no longer nothing more than a child's fantasy. At this moment in the cities below us, the first mechanical men are being constructed that will have the capability to pilot the ship on its maiden voyage. But no one has asked if this dream we've had for so long will lose its value once it's realized. What will happen when those mechanical men step out of their ship and onto the surface of this moon, which has served humanity for thousands of years as our principal icon of love and madness? When they touch their hands to the ground and perform their relentless analyses and find no measurable miracles, but a dead gray world of rocks and dust? When they discover that it was the strength of millions of boyhood daydreams that kept the moon aloft, and that without them that murdered world will fall, spiraling slowly down and crashing into the open sea?

Space is often compared to our oceans. Throw a stone at the water and the density smothers its propulsion. Skim the stone across the surface and the propulsion is mostly preserved with minimal drag. This kind of approach could work for NASA's mission to Mars.

Space: the gaping hole between land and other land.

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.

Standard procedure; the usual high volume of paperwork required to even sneeze on another planet.

Sometime we don't always get what we want!" shouted Evie, not knowing herself. "That's life!"... The Captain, still looking at her, raised his eyebrows in surprise. He was proud of her for being brave enough to shout at (the villain), but he said softly to her, "Usually men with knives at your friend's neck get what they want, Evelyn.

The moon is considered a relatively easy object to land humans on, everything else is much harder by orders of magnitude. It is the reason why we have not been to Mars and will likely never go there successfully with humans.

THERE IT IS,’ my mother says, and what she means is that the dot we’ve been nearing for weeks, the one that’s been growing into a larger dot with two smaller dots circling it, has now become even larger than that, growing from a dot to a disc, shining back the light from its sun, until you can see the blue of its oceans, the green of its forests, the white of its polar caps, a circle of colour against the black beyond.

There are often evolutionary parallels on the different worlds because creation tends to be economical.

That was a hell of a thing.

There is nothing new under the sun, but there are new suns.

These beings, with soaring imagination, eventually flung themselves and their machines into interplanetary space.

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.

To the rocket scientist, you are a problem. You are the most irritating piece of machinery he or she will ever have to deal with. You and your fluctuating metabolism, your puny memory, your frame that comes in a million different configurations. You are unpredictable. You're inconstant. You take weeks to fix. The engineer must worry about the water and oxygen and food you'll need in space, about how much extra fuel it will take to launch your shrimp cocktail and irradiated beef tacos. A solar cell or a thruster nozzle is stable and undemanding. It does not excrete or panic or fall in love with the mission commander. It has no ego. Its structural elements don't start to break down without gravity, and it works just fine without sleep. To me, you are the best thing to happen to rocket science. The human being is the machine that makes the whole endeavor so endlessly intriguing.

These stories are true. They just haven't happened yet.

We are in the process of finding out what filling the sky with hundreds of thousands of satellites does to all life on Earth.

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard. [Address at Rice University, September 12 1962]

The science done by the young Einstein will continue as long as our civilization, but for civilization to survive, we'll need the wisdom of the old Einstein -- humane, global and farseeing. And whatever happens in this uniquely crucial century will resonate into the remote future and perhaps far beyond the Earth, far beyond the Earth

Why travel to the Moon or Mars if we only continue our wars there with Russia or China or Africa? Why build rockets at all? For fun? For adventure? Or is this the same process that sends the salmons back upstream year after year to spawn and die - a subliminal urge in mankind to spread, in self-preservation, to the stars? Are we then secretly fearful that one day the sun might freeze and the the earth grow cold or the sun explode in a terrific thermal cataclysm and burn down our house of cards?

Whatever the reason we first mustered the _Apollo_ program, however mired it was in Cold War nationalism and the instruments of death, the inescapable recognition of the unity and fragility of the Earth is its clear and luminous dividend, the unexpected final gift of _Apollo_. What began in deadly competition has helped us to see that global cooperation is the essential precondition for our survival. Travel is broadening. It's time to hit the road again.

When it comes to travelling to Mars, we either pursue physical paths and redesign our spacecraft with improved radiation-shielding and staggering fuel-efficiency. Or we cheat a little and bend the space/time continuum to get there.

60,000 kilometres per second may be the practical (!) speed limit for space travel

You ask me to make peace with the monsters who did this?” She didn’t even look around at ‘this.’ “Yes. The alternative is extinction. There’s no coming back from that—no new weapon to fire when no one is left and you’ve no universe left to fire it in.

You think this is a walk in the park, that it’s all beauty pageants and tea parties? Come on girl, wake up! This is survival at its most intense.

Advanced weaponry, victories in battle and space travel do not an advanced species or civilization make.

Alex screamed and lashed out at the points of light from within, desperate for something tangible to rage against. Caleb wrapped his arms around her from behind and coaxed her out while glaring at the Metigen in loathing. Then he lessened his hold on her to a single hand. Together they turned their backs on the alien and began walking away.

You can't show me the Earth from space and fly right past the moon, entice me into this magical machine and invite me to come with you, and then ask me to stay behind!

Ah, youth! It was a beautiful night... The moon was out of orbit. The stars were awry. But everything else was exactly as it should have been.

Children are turning themselves into monsters and, quite frankly, it is your fault. You initiated the creation of this technology, then you allowed it to slip through your fingers.” Miriam’s jaw tightened. “I disagree, but now is the least optimal time imaginable for assigning blame. People are dying, and I will not stand around debating semantics with you while they are.
