The American and Russian capabilities in space science and technology mesh; they interdigitate. Each is strong where the other is weak. This is a marriage made in heaven - but one that has been surprisingly difficult to consummate.
Cuando hablamos de la "ira" del cielo, la "agitación" del mar, la "resistencia" de los diamantes a ser tallados, la "atracción" que ejerce la Tierra sobre un asteroide cercano o la "excitación" de un átomo, de nuevo pensamos en una especie de vis...
Pero ¿por qué hemos de empeñarnos en pensar que el universo fue hecho para nosotros? ¿Por qué resulta tan atractiva esa idea? ¿Por qué seguimos alimentándola? ¿Es tan precaria nuestra autoestima que no podemos conformarnos con nada inferior ...
Al parecer anhelamos un privilegio, merecido no por nuestros esfuerzos, sino por nacimiento, digamos que por el mero hecho de ser humanos y de haber nacido en la Tierra. Podríamos llamarla la noción antropocéntrica, "centrada en el ser humano". Es...

The significance of our lives and our fragile planet is then determined only by our own wisdom and courage. We are the custodians of life's meaning. We long for a Parent to care for us, to forgive us our errors, to save us from our childish mistakes....
The visions we offer our children shape the future. It _matters_ what those visions are. Often they become self-fulfilling prophecies. Dreams are maps.
Or consider a story in the Jewish Talmud left out of the Book of Genesis. (It is in doubtful accord with the account of the apple, the Tree of Knowledge, the Fall, and the expulsion from Eden.) In The Garden, God tells Eve and Adam that He has intent...
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more ...
A blade of grass is a commonplace on Earth; it would be a miracle on Mars. Our descendants on Mars will know the value of a patch of green. And if a blade of grass is priceless, what is the value of a human being?
The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of the worlds - to say nothing of stars or galaxies - humans are inconsequential, a thin film of life on an obscure and solitary lump of r...
Science cuts two ways, of course; its products can be used for both good and evil. But there's no turning back from science. The early warnings about technological dangers also come from science.
The Cosmos extends, for all practical purposes, forever. After a brief sedentary hiatus, we are resuming our ancient nomadic way of life. Our remote descendants, safely arrayed on many worlds throughout the Solar System and beyond, will be unified by...
These days there seems to be nowhere left to explore, at least on the land area of the Earth. Victims of their very success, the explorers now pretty much stay home.
There is every reason to think that in the coming years Mars and its mysteries will become increasingly familiar to the inhabitants of the Planet Earth.
Whatever the reason we first mustered the _Apollo_ program, however mired it was in Cold War nationalism and the instruments of death, the inescapable recognition of the unity and fragility of the Earth is its clear and luminous dividend, the unexpec...
There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why no...
I do not think it irresponsible to portray even the direst futures if we are to avoid them we must understand that they are possible. But where are the alternatives Where are the dreams that motivate and inspire We long for realistic maps of a world ...
