The Queen of Air and Darkness

The Queen of Air and Darkness

One lightyear is not much as galactic distances go. Your could walk it in about 270 million years, beginning at the middle of the Permian Era, when dinosaurs belonged to the remote future, and continuing to the present day when spaceships cross even greater reaches. But stars in our neighborhood average some nine lightyears apart, and barely one percent of them have planets which are man habitable, and speeds are limited to less than that of radiation. Scant help is given by relativistic time contraction and suspended animation en route. These make the journeys seem short, but history meanwhile does not stop at home.

This voyages from sun to sun will always be few. Colonists will be those who have extremely special reasons for going. They will take along germ plasm for exogenetic cultivation of domestic plants and animals - and of human, in order that population can grow fast enough to escape death through genetic drift. After all, they cannot rely of further immigration. Two or three times a century, a ship may call from some other colony. (Not from Earth. Earth has long ago sunk into alien concerns.) Its place of origin will be an old settlement. The young ones are in no position to build and man interstellar vessels.

Their very survival, let alone their eventual modernization, is in doubt. The founding fathers have had to take what they could get in a universe not especially designed for man.

Consider, for example, Roland. It is among the rare happy find, a world where humans can live, breathe, eat the food, drink the water, walk unclad if they choose, sow their crops, pasture their beasts, dig their mines, erect their homes, raise their children and grandchildren. It is worth crossing these quarters of a light-century in preserve certain dear values and strike new roots into the soil or Roland.

But the star Charlemagne is of type F9, forty percent brighter than Sol, brighter still in the treacherous ultraviolet and wilder still in the wind of charged particles that seethes front it. The planet has an eccentric orbit. In the middle of the short but furious northern summer, which includes periastron, total isolation is more than double what Earth gets; in the depth of the long northern winter, it is barely less than Terrestrial average.

Native life is abundant everywhere. But lacking elaborate machinery, not yet economically possible to construct for more than a few specialists, man can only endure the high latitudes. A ten-degree axial tilt, together with the orbit, means that the northern part of the Arctican continent spend half its year in unbroken sunlessness. Around the South Pole lies an empty ocean. Roland

Other differences from Earth might superficially seem more important. Roland has two moons, small but close, to evoke clashing tides. It rotates once in thirty-two hours, which is endlessly, subtly disturbing to organisms evolved through gigayears of a quicker rhythm. The weather patterns are altogether unterrestrial. The globe is a mere 9500 kilometers in diameter; its surface gravity is 0.42x980 cm/sec2; the sea level air pressure is slightly above one Earth atmosphere. (For actually Earth is the freak, and man exists because a cosmic accident blew away most of the gas that a body its size ought to have kept, as Venus has done).
