I see nothing to fear in inner space.
A lot of the films I like are more than fantasies - they're movies fascinated by the technology of space exploration, and they try to honor the laws of physics. I watched the Gregory Peck movie 'Marooned' over and over when I was a kid.
Everyone, red state, blue state, everyone supports space exploration.
The news media reported the $250 million as an unthinkably huge waste of money and proclaimed that something was wrong with NASA. The result was an investigation and a congressional hearing. Not to defend failure, but $250 million is not much more than the cost to produce Kevin Costner's film flop Waterworld.
I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.
Our future lies with today's kids and tomorrow's space exploration.
Space exploration is a force of nature unto itself that no other force in society can rival.
If you want a nation to have space exploration ambitions, you've got to send humans.
Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.
We can lick gravity, but sometimes the paperwork is overwhelming.
I have a strong feeling about interesting people in space exploration. . . . And the only way it's going to happen is to have some kid fantasize about getting his ray gun, jumping into his spaceship, and flying into outer space.
Don't tell me that man doesn't belong out there. Man belongs wherever he wants to go - and he'll do plenty well when he gets there.
Houston, Tranquillity Base here. The Eagle has landed.
I believe we need a more opportunistic and democratic approach to lunar exploration, now that we're shifting from U.S. government-sponsored space exploration to private expeditions.
I think we are at the dawn of a new era in commercial space exploration.
We stand on a great threshold in the human history of space exploration. If life is prevalent in our neighborhood of the galaxy, it is within our resources and technological reach to be the first generation in human history to finally cross this threshold, and to learn if there is life of any kind beyond Earth.
When deep space exploration ramps up, it'll be the corporations that name everything, the IBM Stellar Sphere, the Microsoft Galaxy, Planet Starbucks.
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.
God has no intention of setting a limit to the efforts of man to conquer space.
We had various kinds of tape-recorded concerts and popular music. But by the end of the flight what we listened to most was Russian folk songs. We also had recordings of nature sounds: thunder, rain, the singing of birds. We switched them on most frequently of all, and we never grew tired of them. It was as if they returned us to Earth.
Machines taking over jobs - it's the history of civilization. Replacing farm animals, old forms of manual labor, now taking over small, menial aspects of cognition. But there's still plenty of room for creativity, for curiosity - many things that are related to passion, like art. But also, things about human communication and challenges, massive challenges that we left behind because we didn't want to take so much risk, such as space exploration, deep ocean exploration.
To most people in the UK, indeed throughout Western Europe, space exploration is primarily perceived as 'what NASA does'. This perception is - in many respects - a valid one. Superpower rivalry during the Cold War ramped up US and Soviet space efforts to a scale that Western Europe had no motive to match.
Mars is the next frontier, what the Wild West was, what America was 500 years ago. It's time to strike out anew....Mars is where the action is for the next thousand years....The characteristic of human nature, and perhaps our simian branch of the family, is curiosity and exploration. When we stop doing that, we won't be humans anymore. I've seen far more in my lifetime than I ever dreamed. Many of our problems on Earth can only be solved by space technology....The next step is in space. It's inevitable.
This is in a real sense the capstone of the initial missions to explore the planets. Pluto, its moons and this part of the solar system are such mysteries that New Horizons will rewrite all of the textbooks.
If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds. Sailors on a becalmed sea, we sense the stirring of a breeze.
India has no dearth of brave young men and women and if they get the opportunity and help then we can compete with other nations in space exploration and one of them will fulfil her dreams.
We'll get to the details of what's around here, but it looks like a collection of just about every variety of shape - angularity, granularity, about every variety of rock.... The colors - well.... There doesn't appear to be too much of a general color at all; however, it looks as though some of the rocks and boulders are going to have some interesting colors to them. Over.
I think space exploration is very important. I think there is very intelligent life on Mars. I believe that Martians are spying on us from the bottom of the ocean.
As I looked down, I saw a large river meandering slowly along for miles, passing from one country to another without stopping. I also saw huge forests, extending along several borders. And I watched the extent of one ocean touch the shores of separate continents. Two words leaped to mind as I looked down on all this: commonality and interdependence. We are one world.
Geez, all that money we waste on space exploration; just think how many bombs that would buy!
If you go far enough out you can see the Universe itself, all the billion light years summed up time only as a flash, just as lonely, as distant as a star on a June night if you go far enough out. And still, my friend, if you go far enough out you are only at the beginning - of yourself.
Feeling weightless... it's so many things together. A feeling of pride, of healthy solitude, of dignified freedom from everything that's dirty, sticky. You feel exquisitely comfortable... and you feel you have so much energy, such an urge to do things, such an ability to do things. And you work well, yes, you think well, without sweat, without difficulty as if the biblical curse in the sweat of thy face and in sorrow no longer exists, As if you've been born again.
There are so many benefits to be derived from space exploration and exploitation; why not take what seems to me the only chance of escaping what is otherwise the sure destruction of all that humanity has struggled to achieve for 50,000 years?
In the coming era of manned space exploration by the private sector, market forces will spur development and yield new, low-cost space technologies. If the history of private aviation is any guide, private development efforts will be safer, too.
When provoked, the itsy-bitsy invertebrates known as tardigrades can suspend their metabolism. In that state, they can survive temperatures of... 73 K for days on end, making them hardy enough to endure being stranded on Neptune. So the next time you need space travelers with the right stuff, you might want to choose yeast and tardigrades, and leave your astronauts, cosmonauts, and taikonauts at home.
The great thing about being an astronaut is you kind of get to do a little bit of everything. I mean, we're going to ride a rocket uphill.
Cooperating in something as visible as space exploration and space flight can only improve relations between the two countries because what happens is, you're working on a common project in a very visible light and so, you're motivated to not have conflicts with each other in other areas. And bringing up China is a good example. In the early '90's, China got serious about wanting to launch astronauts into space and they were actually quite successful in launching many communication satellites. They went ahead and in 2003 they launched their first astronaut into space.
I grew up in California. I was outside of the city, not directly in it. So I did have an experience of the sky, but for me, it was the idea of space exploration that fueled my interest. I grew up in that age of the astronauts, and I was fascinated that we could leave the Earth.
I remember growing up thinking that astronauts and their job was the coolest thing you could possibly do... But I absolutely couldn't identify with the people who were astronauts. I thought they were movie stars.
It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.
And then, the Earth being small, mankind will migrate into space, and will cross the airless Saharas which separate planet from planet and sun from sun. The Earth will become a Holy Land which will be visited by pilgrims from all the quarters of the Universe. Finally, men will master the forces of Nature; they will become themselves architects of systems, manufacturers of worlds.
This has been far more than three men on a mission to the Moon; more still than the efforts of a government and industry team; more, even, than the efforts of one nation. We feel this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown.
It will free man from the remaining chains, the chains of gravity which still tie him to this planet.
I am very much against weapons in space. And I wish we could be spearheading that program to come to some kind of international agreement so that doesn't happen. That is my only - fear - in further space exploration like always, we hope it doesn't get abused
By refocusing our space program on Mars for America's future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it's time for us to live and work on Mars, first on its moons and then on its surface.
I've completed half of my space training at Space City in Moscow. I love adventure, and I've been training in a centrifuge and MiG Fighter with a view to going into space and being a spokesman for space exploration!
No one, it has been said, will ever look at the Moon in the same way again. More significantly can one say that no one will ever look at the earth in the same way. Man had to free himself from earth to perceive both its diminutive place in a solar system and its inestimable value as a life -fostering planet. As earthmen, we may have taken another step into adulthood. We can see our planet earth with detachment, with tenderness, with some shame and pity, but at last also with love.
A sense of the unknown has always lured mankind and the greatest of the unknowns of today is outer space. The terrors, the joys and the sense of accomplishment are epitomized in the space program.
Today, we are on a path of decay. We are seeing the book close on five decades of accomplishment as the leader in human space exploration.
