I'm sure we would not have had men on the Moon if it had not been for Wells and Verne and the people who write about this and made people think about it. I'm rather proud of the fact that I know several astronauts who became astronauts through reading my books.
In 1960-61, a small group of female pilots went through many of the same medical tests as the Mercury astronauts and scored very well on them - in fact, better than some of the astronauts did.
That's what we want to do here at Johnson Space Center. I think what we have always brought to NASA and brought to the country is trying to push the boundaries, trying to go to the next level.
The first man-made satellite to orbit the earth was named Sputnik. The first living creature in space was Laika. The first rocket to the Moon carried a red flag. The first photograph of the far side of the Moon was made with a Soviet camera. If a man orbits the earth this year his name will be Ivan.
I don't think we should have to do a Mars mission on the basis of hysteria. I think we should do a Mars mission on the basis of a deliberate judgment that what we want to do is open up a new planet for humanity... that we are continuing to be a nation of pioneers.
There are aspects of being the first woman in space that I'm not going to enjoy.
There will certainly be no lack of human pioneers when we have mastered the art of flight....Let us create vessels and sails justed to the heavenly ether, and there will be plenty of people unafraid of the empty wastes. In the meantime we shall prepare, for the brave sky-travelers, maps of the celestial bodies.
'Boldly going where hundreds have gone before' does not make headlines.
I am deeply grieved by the loss of the crew of Columbia. I express my sincere condolences to the families and friends of the astronauts. I believe that their names will remain as the bright sparkling stars in the universe and will light the way for those who will follow them on the difficult roads of space exploration.
Like prospecting in the 19th century, reconnaissance of the asteroids would of necessity take place in an arena where trouble is likely and help is distant. Heroic stories of individual triumph and failure, set on landscapes never seen by humankind, are in the cards.
We must still think of ourselves as pioneers to understand the importance of space.
We collectively have a special place in our heart for the manned space flight program - Apollo nostalgia is one element, but that is only part of it. American culture worships explorers - look at the fame of Lewis and Clark, for example. The American people want to think of themselves as supporting exploration.
One of the astronauts I came to admire the most is John Young.
I suppose the one quality in an astronaut more powerful than any other is curiosity. They have to get some place nobody's ever been.
The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.
Yuri Gagarin, the first man in space, may have had his charms, but he really couldn't be considered hip.
Star Trek's genial premise is that the cosmos is flush with intelligent species, and our descendants will interact with them face-to-face, thanks to warp drive and some winsome space cadets.
The commercial space industry owes a huge debt to Patti Grace Smith. There might not be a commercial spaceflight industry were it not for Patti's leadership.
A day will come when other Israelis will be launched into space in the service of science and progress. For them and for us, Ilan Ramon will always be a source of inspiration as Israel's space pioneer, and his memory will be engraved in our hearts forever.
When the history books are written in a thousand years, when space travel would have become routine, the moment that humans first left Earth will be of huge importance. Star City is a central part of this story and it deserves more recognition.
Space is a harsh, inhospitable frontier and we are explorers, not colonisers. The skills of our engineers and the technology surrounding us make things appear simple when they are not, and perhaps we forget this sometimes. Better not to forget.
Most of our history in space has been communicated in terms of action - what people do, a chronological list of events which have transpired - as opposed to the human experience of having done those things.
The leader of an Earth organization who makes a commitment to history - of humans living on Earth, to begin permanent settlement/occupation of not the moon, but of another planet - this leader will have a legacy for history that will supersede Columbus, Genghis Khan or almost any recognized leader.
I suppose there wasn't a well-worn path into the British space programme because we didn't really have a space programme. Dad was one of the pioneers of it.
I would enjoy flying to Mars. This was the dream of the first cosmonauts. I wish I could realize it! I am ready to fly without coming back.
