People say- 'NASA lies.' I say- 'the moon knows it all. Look at the moon and forget the spinning flat world.

An invention is a responsibility of the individual, society cannot invent, it can only applaud the invention and inventor.

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.)

Turns out even NASA can't improve on duct tape.

Mars will not be our new home; it will be our new hotel! Because for a new place to be our own home, we need to see the things we used to see: An autumn lake, a bird singing in the misty morning or even desert camels walking in the sunset!

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.

Spaceflight will never tolerate carelessness, incapacity, and neglect.

NASA astronauts have only managed to live continuously on the International Space Station (ISS) for a year and Biosphere 2 on Earth failed at two years of uninterrupted human habitation. Both cases required extracting the sickened people from the toxic environments. At this point it is ludicrous to talk about a permanent manned base on Mars.

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.

This is the second Old Master I have encountered that has the signatures of another artist forged over it. A painting that has been created by another artist entirely. It's like they played mix and match.

Don't tell me the sky is the limit - there's footprints on the Moon. - Overheard at a flee market.

With an accelerated schedule of launch in just two months, NASA and contractor launch and support teams labor steadily with six-day work weeks by day and night shifts

The complete Apollo team...directly involves slightly over 400,000 people...Included are some if the country's foremost scientists and engineers. This mobilization of men and resources is unprecedented in history since WWII

There was virtually no aspect of twentieth-century defense technology that had not been touched by the hands and minds of female mathematicians.

I'm fairly certain that, at this very minute, the [Mars Polar Lander] is floating somewhere around the Neptune feeling tired and cranky and looking for a Holiday Inn.Of course, you'd have to have a heart of titanium not to feel a twinge of sadness while watching those dejected NASA scientiest waiting by the phone like the class wallflower on prom week.On the other hand, it was kind of fun to watch a bunch of men waiting by the phone and seeing how they feel when someone promises they'll call and then YOU NEVER HEAR FROM HIM AGAIN.

I am, like you, travelling along a road of absolute uncertainty and chaos. The only truth is that one day, we will all reach the end.

The scary thing about the protective properties of dietary intake regarding abnormal human radiation exposures is that NASA has understood this for decades!

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.

Thank you, NASA, for keeping watch and realizing that our universe will never be anything but light-years new. I want to understand that, and I am so comforted by the fact that I can't. It only proves that some things won't allow themselves to be understood. They aren't for us to know and there's rapture in that, don't you think? Are you happy there, with your eyes glued to the heavens? You know so much, like why the ocean doesn't fall out of the sky, and that there is no upside down. There is no up.

Science, enabled by engineering, empowered by NASA, tells us not only that we are in the universe but that the universe is in us. And for me, that sense of belonging elevates, not denigrates, the ego.

I was impressed by the scene in Apollo 13 where the astronauts request confirmation of their calculations and several people at Mission Control dive for their slide rules. For several months after that, my standard response to statements like "We must implement multi-processor object-oriented Java-based client-server technologies immediately!" was "You know, FORTRAN and slide rules put men on the moon and got them back safely multiple times."Tended to shut them up, at least for a moment.

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, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.

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.

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.

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.

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.

If someone asked me to sum up what is great about my country, I would probably tell them about Apollo 11, about the four hundred thousand people who worked to make the impossible come true within eight years, about how it changed me to see the space-scarred Columbia capsule in a museum as a child, about how we came in peace for all mankind.

Histories of the Kennedy Space Center acknowledge without exaggeration that the obstacle posed by the mosquitoes was so serious that NASA quite literally could not have put a man on the moon by Kennedy's "before the decade is out" deadline without the invention of DDT. In this way, the challenges of spaceflight reveal themselves to be distinctly terrestrial.

Together the five orbiters Columbia, Challenger, Discovery, Atlantis, and Endeavour have flown a total of 133 successful missions, an unequaled accomplishment of engineering, management, and political savvy. But it's the two disasters that people remember, that most shape the shuttle's story. The lovely dream of spaceflight I grew up with is marred by the images of Challenger and Columbia breaking apart in the sky, the lost astronauts smiling on hopefully in their portraits, oblivious. Some people took the disasters to mean the entire space program had been a lie, that the dream itself was tainted with our fallibility. But even as a child, I knew it was more complex than that. If we want to see people take risks, we have to be prepared to sometimes see them fail. The story of American spaceflight is a story with many endings, a story of how we have weighed our achievements against our failures.

Space is dangerous. It's what we do here. If you want to play it safe all the time, go join an insurance company.

When you organize extraordinary missions, you attract people of extraordinary talent who might not have been inspired by or attracted to the goal of saving the world from cancer or hunger or pestilence.

Within a year, possibly by next fall," he was saying, "something that has never before been done, will be done. NASA will be sending men to the moon. Think of that. Men who were once in classrooms like this one will leave their footprints on the lunar surface." He paused. I leaned in close against the wall so I could hear him. "That is why you are sitting here tonight, and why you will be coming here in the months ahead. You come to dream dreams. You come to build fantastic castles up in the air. And you come to learn how to build the foundations that make those castles real. When the men who will command that mission were boys your age, no one knew. But in a few months, that's what will happen. So, twenty years from now, what will people say of you? 'No one knew then that this kid Washington Irving High School would grow up to do'...what? What castle will you build?
