“The fastest that human spacecraft are likely to achieve in the twenty-first century, I think, is 300 kilometres per second.”
Kip S. Thorne“While human spaceflight is certainly compelling – and it has always been a big part of my reporting career -- there is something about unmanned robotic spacecraft that has always tugged at my heart. These machines are our emissaries out into the cosmos, flung to faraway places that humans can’t yet visit. I grew up hearing about spacecraft like Mariner, Viking and Voyager boldly going on some of the first-ever deep space missions and making monumental discoveries that changed our view of the Solar System. They showed us worlds we previously could only dream about and artists could only imagine.”
Nancy Atkinson, Incredible Stories from Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos“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.”
Margaret Lazarus Dean, Leaving Orbit: Notes from the Last Days of American Spaceflight“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.”
Margaret Lazarus Dean, Leaving Orbit: Notes from the Last Days of American Spaceflight“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.”
Mark Haddon, The Curious Incident of the Dog in the Night-Time“It is of course dangerous to set off an explosive device on a spacecraft.”
Andy Weir, The Martian“I left Aerospace because I wanted to go build, and put spacecraft together.”
Gwynne Shotwell“It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.”
Rusty Schweickart“The winners in life treat their body as if it were a magnificent spacecraft that gives them the finest transportation and endurance for their lives.”
