Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

And all dared to brave unknown terrors, to do mighty deeds, to boldly split infinitives that no man had split before--and thus was the Empire forged.

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.

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?

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 , but that's not accurate. People object. They object a lot.

She preferred the times when she could pretend that she was in a gravity well to the little reminders that she was the puppet of acceleration and inertia.

Gravity is why there are suns and planets in the first place. It is practically God.

"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.

In retrospect, it was silly to think that the experience of traveling in space could be approximated by a repurposed walk-in freezer. To find out what would happen to a man alone in the cosmos, at some point you just had to lob one up there.
