By the time I'm 40, interplanetary travel will be common. Nobody will want to talk to me at that age, anyway.

I've always liked Saturn. But I also have some sympathy for Pluto because I heard it's been downgraded from a planet, and I think it should remain a planet. Once you've given something planetary status it's kind of mean to take it away.

My childhood dreams were focused on being part of the effort to make humanity a multiplanetary species.

There is a project that's underway called the interplanetary Internet. It's in operation between Earth and Mars. It's operating on the International Space Station. It's part of the spacecraft that's in orbit around the Sun that's rendezvoused with two planets.

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.

Man is the animal that intends to shoot himself out into interplanetary space, after having given up on the problem of an efficient way to get himself five miles to work and back each day.

If you go to planetary science meetings and hear technical talks on Pluto, you will hear experts calling it a planet every day.

In the seventeenth century, the science of medicine had not wholly cut asunder from astrology and necromancy; and the trusting Christian still believed in some occult influences, chiefly planetary, which governed not only his crops but his health and life.

The future of humanity is going to bifurcate in two directions: Either it's going to become multiplanetary, or it's going to remain confined to one planet and eventually there's going to be an extinction event.

I do comparative studies of climate evolution, and the interactions between planetary atmosphere and surfaces and their radiation environment, and try to understand the environmental factors that can affect a planet's habitability and how they change over time.

Ever since the environmental movement was sparked by photos of the whole Earth taken by astronauts onboard Apollo Lunar Modules, I've seen planetary exploration as an extension of a reverence and care for Earth.

Threats that could wipe out the bulk of life on earth abound. Planetary catastrophe could come in the form of a killer asteroid impact, the eruption of massive supervolcanoes, a nearby gamma ray burst that sterilizes the earth, or by human-driven environmental collapse.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.

What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.

Commercialization of assets off the planet would mutually reinforce the growth of interplanetary communication.

There is no fixed physical reality, no single perception of the world, just numerous ways of interpreting world views as dictated by one's nervous system and the specific environment of our planetary existence.

#1 TRUTH OF LIFE: Every person has their own set of beliefs/values/perceptions/opinions as all have varying degree of energy/consciousness. So likes, dislikes, decisions & actions and hence, soul path of every person is different. Also the mindset of people keep on changing with changing times caused by changes in the planetary positions, which changes the energy and thus, mindset of a person.

Sitting there on the heather, on our planetary grain, I shrank from the abysses that opened up on every side, and in the future. The silent darkness, the featureless unknown, were more dread than all the terrors that imagination had mustered. Peering, the mind could see nothing sure, nothing in all human experience to be grasped as certain, except uncertainty itself; nothing but obscurity gendered by a thick haze of theories. Man's science was a mere mist of numbers; his philosophy but a fog of words. His very perception of this rocky grain and all its wonders was but a shifting and a lying apparition. Even oneself, that seeming-central fact, was a mere phantom, so deceptive, that the most honest of men must question his own honesty, so insubstantial that he must even doubt his very existence.

A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If as some evidence suggests exotic micro-organisms have arisen independently of terrestrial life studying them could revolutionise biology medicine and biotechnology.

I believe it is essential for our planetary future to develop tools that can change the consciousness which has created the crisis that we are in.
