J. B. Priestley Quotes

As we visit Mars multiple times, we will build up infrastructure on the surface to expand the capabilities and reach of humans on Mars.

It's not going to do any good to land on Mars if we're stupid.

Exploration of closer planets will continue. Only after he exhausts all the resources here on earth will man go further ahead, which is when interplanetary travel may take place.

Will we have a colony on Mars? I think so.

By going to Mars one day, we will make things better for us here on Earth.

We imagine going to the moon and planting a flag, going to an asteroid and mining, going to Mars and setting up a colony. And I think that expansionist mentality is very self-destructive, especially given the kind of precarious relationship we now have to the ecosystem here on Earth, because it allows us to imagine that Earth is disposable.

I believe that the long-term future of the human race must be space and that it represents an important life insurance for our future survival, as it could prevent the disappearance of humanity by colonizing other planets.

Well, we now have such a photograph... Has any new idea been let loose? It certainly has. You will have noticed how suddenly everybody has become seriously concerned to protect the natural environment... It seems to me more than a coincidence that this awareness should have happened at exactly the moment man took his first step into space.

Every single astronaut who has come back from space comes back determined to do more to protect it.

No rocket will reach the moon save by a miraculous discovery of an explosive far more energetic than any known. And even if the requisite fuel were produced, it would still have to be shown that the rocket machine would operate at 459 degrees below zero-the temperature of interplanetary space.

Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space.

I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets, which obviously are a little more technically advanced than we are here on earth.

If anything, when you're up in space and you're inside a space ship, which is your home, and without which you would not survive, you know that Earth is your home. This is the only place you can return. In fact we're very meticulous. Part of our job is to maintain the spaceship. If we apply the same kind of model to Earth maybe we'd have a different outlook.

President Bush wants to build a space station on the moon. And from the moon, he wants to launch people to Mars. You know what this means. He's been drinking again.

The future is about wings and wheels and new forms of space transportation, along with our deep-space ambition to set foot on another world in our solar system: Mars. I firmly believe we will establish permanence on that planet. And in reaching for that goal, we can cultivate commercial development of the moon, the asteroid belt, the Red Planet itself and beyond.

The desired effect is what you get when you improve your interplanetary funksmanship.

Space travel is life-enhancing, and anything that's life-enhancing is worth doing. It makes you want to live forever.

I do not foresee 'spaceships' to the moon or Mars. Mortals must live and die on Earth or within its atmosphere!

If [Bush's] successors don't screw it up, within 10 years NASA will have us back to where we belong -- on other worlds.

In my considered opinion, the profit to be made by permanent settlement in space is nothing less than the survival of industrial civilization, and therefore the survival of nearly the entire human race, along with such amenities as peace, freedom, enough to eat, and the chance to reach a high age in good health.

We've sent a man to the moon and that's 29,000 miles away. The center of the Earth is only 4,000 miles away. You could drive that in a week but for some reason nobody's ever done it.

In 1492 Columbus knew less about the far Atlantic than we do about the heavens, yet he chose not to sail with a flotilla of less than three ships. . . . So it is with interplanetary exploration: it must be done on the grand scale.

Will we go explore? Absolutely. That's what humans have been doing since we left the caves in Ethiopia. Why? Because this is part of our nature. We're curious. We want to push the envelope. That will never stop. We will see people on Mars, hopefully in our lifetime. My hope is that the endeavour is so large, so complex, so technically challenging, so demanding and so uplifting, that it will be done with a consortium of nations. I hope the people who do set foot on Mars will do so for all mankind, and not just one nation in particular.

I can't think that leaving Earth once is enough.

I want to make rockets 100 times, if not 1,000 times better. The ultimate objective is to make humanity a multiplanet species. Thirty years from now, there'll be a base on the moon and on Mars, and people will be going back and forth on SpaceX rockets.
