"Space exploration is a force of nature unto itself that no other force in society can rival."
- Neil deGrasse Tyson
Maria Corte Maidagan
"Life is an unfoldment, and the further we travel the more truth we can comprehend. To understand the things that are at our door is the best preparation for understanding those that lie beyond."
"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."
- Annabella Sciorra
"I'm really hopeful about the future of space exploration and human spaceflight. Civilization as we know it has been defined by exploration. You know, we need to go off and find out what's around the next corner and what's just beyond what we already know. It's part of our being; it's part of our moral fiber to go off and explore."
- Alan G. Poindexter
"Is manned space exploration important? Yes - not least because it simply works much better than sending robots."
- Henry Spencer
"Looking down the road, space exploration and the benefits it yields - in medicine and information technology - should not be overlooked."
- Bob Barr
"I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars."
- Stephen Hawking
"I think we are at the dawn of a new era in commercial space exploration."
- Elon Musk
"When someone tells me, 'Oh, we have so many problems on Earth; space exploration costs too much money,' I say, 'I absolutely agree with you. But I still hope we do it.' "
- Mary Roach
"If you want a nation to have space exploration ambitions, you've got to send humans."
- Neil deGrasse Tyson
"One of the big things about space exploration is that it is as expensive as it is complicated, and you need all the countries of the world to help if you want to accomplish big goals."
- Ellen Stofan
"Revealing water in significant quantities on the Moon could truly be a turning point in space exploration."
- Peter Diamandis
"People make their own fates, and if enough of us make our fate to be space explorers, perhaps we can actually get some space exploration done."
- Robert Zubrin
"When I orbited the Earth in a spaceship, I saw for the first time how beautiful our planet is. Mankind, let us preserve and increase this beauty, and not destroy it!"
- Yuri Gagarin, Russian Cosmonaut
"If we ever start communicating with living creatures from other planets, the number one priority is, how are you going to communicate information? Even between different cultures here on Earth, you get into communication problems."
- Story Musgrave
"Anything that stimulates the public's imagination about the nobility and the importance of space exploration is something that I'm very excited to be a part of."

"The day that science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence."
- Nikola Tesla
"To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge."
- Nicolaus Copernicus
"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."
- Wernher von Braun, Rocket Engineer
"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."
- Burt Rutan
"I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets. Most astronauts were reluctant to discuss UFOs."
- Gordon Cooper
"We'd never have got a chance to go outside and look at the earth if it hadn't been for space exploration and NASA."
- James Lovelock
"Once solved, the severe handicaps imposed on space exploration by the weight and chemical limitations of rockets would no longer apply. The whole timetable of our conquest of the planets in our solar system would be tremendously speeded up, from hot Mercury all the way out to frigid Pluto."
- Donald A. Wollheim
"I've always been interested in the idea of space exploration. When I was younger it was just a dream, but the theory of rockets being able to travel through space was very much alive. I found it very exciting."
- Gerry Anderson
"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."
- Scott Bakula
"God has no intention of setting a limit to the efforts of man to conquer space."
- Pope Pius XII
"To be the first to enter the cosmos, to engage, single-handed, in an unprecedented duel with nature - could one dream of anything more?"
- Yuri Gagarin
"Space exploration promised us alien life, lucrative planetary mining, and fabulous lunar colonies. News flash, ladies and gents: Space is nearly empty. It's a sterile vacuum, filled mostly with the junk we put up there."
- Graham Hawkes
Ana Gomez Bernaus
"I didn’t feel like a giant. I felt very, very small."
- Neil Armstrong on looking back at the Earth from the Moon in July 1969
