We were on the dark side of the Earth when we started to see outside the window this soft pink glow, which is a lot of little angry ions out there going very fast. We were hitting them very fast. – Robert Crippen
The frontier in space, embodied in the space colony, is one in which the interactions between humans and their environment is so much more sensitive and interactive and less tolerant of irresponsibility than it is on the whole surface of the Earth. – Rusty Schweickart
There is no country on Earth where Internet and telecommunications companies do not face at least some pressure from governments to do things that would potentially infringe on users’ rights to free expression and privacy. – Rebecca MacKinnon
We have the capability – physically, technically – to protect the Earth from asteroid impacts. We are now able to very slightly and subtly reshape the solar system in order to enhance human survival. – Rusty Schweickart
If incredible creatures like sharks can exist, why not Bigfoot? When I look at sharks, they’re the most terrifying, monstrous, dinosaur-like things. To this day, I’m so fascinated by them and can’t get my head around how they are on Planet Earth at all. – Rachael Taylor
I remember when Tony Blair came into office, and there was a sense I was thinking, ‘Well, what on Earth am I going to do now?’ until I realized that’s exactly what he was thinking. – Rory Bremner
When I was a kid, which was just after Edison invented moving pictures, there were films that involved aliens coming to Earth for bad purposes. – Seth Shostak
The earth’s biosphere could be thought of as a sort of palace. The continents are rooms in the palace; islands are smaller rooms. Each room has its own decor and unique inhabitants; many of the rooms have been sealed off for millions of years. The doors in the palace have been flung open, and the walls are coming down. – Richard Preston
Jupiter, a world far larger than Earth, is so warm that it currently radiates more internal heat than it receives from the Sun. – Seth Shostak
Unfortunately, we haven’t found many very old rocks on Earth because our planet’s surface is constantly renewed by plate tectonics, coupled with erosion. – Robert Duncan
No animal on the face of the earth could conceive of taxation. You and I work roughly six months a year to pay our local, state and federal taxes. If nothing else, this should convince you that animals are smarter than people. – Rita Mae Brown
The Earth we evolved to inhabit is turning into something more turbulent and unreliable at a pace too fast for most living things to adapt to. – Rebecca Solnit
We are not going to be able to operate our Spaceship Earth successfully nor for much longer unless we see it as a whole spaceship and our fate as common. It has to be everybody or nobody. – R. Buckminster Fuller
Forecasting Armageddon has become trendy of late, with a great deal of attention being given to an interpretation of the Mayan Calendar suggesting that Mother Earth is destined for doom in December of 2012. – Seth Shostak
I you look at the drawings of aliens made by people who believe that Earth is under saucer attack, you’ll quickly note that most of these invaders fit the Tinseltown mold. But you have to admit: the grays are highly anthropomorphic. – Seth Shostak
Somebody who doesn’t care if they live or die is the most dangerous human being on earth. – Ron Perlman
Americans who read the papers or watch Jay Leno have been aware for some time now that there is a slim but real possibility – about 1 in 45,000 – that an 850-foot-long asteroid called Apophis could strike Earth with catastrophic consequences on April 13, 2036. – Rusty Schweickart
Humanity evolves when we realise that animals have the same rights to the Earth as we do. – Radhanath Swami
American audiences tend to underappreciate the British, but 240 years ago they were us: They were the most powerful nation on Earth. Their mercantile empire spanned the planet. They had the most potent and experienced army and navy the world had ever seen. – Rick Atkinson
Do I think I was put here on earth to be a journalist and to seek truth? No, I don’t. – Peter Jennings
The way I see it, the earth is going to be here after we’re dead and gone. Even if it’s a polluted planet, and they messed it up. Where do they go from here – to another planet so they can mess that up too? – Richard Pryor
I’ve driven all through America and I know there are a lot of clever people between the coasts. But they have a slightly old-fashioned view of the world. Whereas New York is one of the most multicultural, multiracial, tolerant places on Earth. – Robbie Coltraine
I don’t really think of myself as a heartthrob. I’ve got a lot of brothers, and there’s a natural competitiveness between us when it comes to girls. If I said something about being a heartthrob, then they would bring me straight back down to earth! – Ross Lynch
