Moving Mars

by Greg Bear

For Ray Bradbury

A day on Mars is a little longer than a day on Earth: 24 hours and 40 minutes. A year on Mars is less than two Earth years: 686 Earth days, or 668 Martian days. Mars is 6,787 kilometers in diameter, compared to Earth’s 12,756 kilometers. Its gravitational acceleration is 3. 71 meters per second squared, or just over one-third of Earth’s. The atmospheric pressure at the surface of Mars averages 5. 6 millibars, about one-half of one percent of Earth’s. The atmosphere is largely composed of carbon dioxide. Temperatures at the “datum” or reference surface level (there is no “sea level,” as there are presently no seas) vary from -130° to +27° Celsius. An unprotected human on the surface of Mars would very likely freeze within minutes, but first would die of exposure to the near-vacuum. If this unfortunate human survived freezing and low pressure, and found a supply of oxygen to breathe, she would still be endangered by high levels of radiation from the sun and elsewhere.

After Earth, Mars is the most hospitable planet in the Solar System.

Part One

The young may not remember Mars of old, under the yellow Sun, its cloud-streaked skies dusted pink, its soil rusty and fine, its inhabitants living in pressurized burrows and venturing Up only as a rite of passage or to do maintenance or tend the ropy crops spread like nests of intensely green snakes over the wind-scoured farms. That Mars, an old and tired Mars filled with young lives, is gone forever.

Now I am old and tired, and Mars is young again.

Our lives are not our own, but by God, we must behave as if they are. When I was young, what I did seemed too small to be of any consequence; but the shiver of dust, we are told, expands in time to the planet-sweeping storm…

2171, M. Y. 53

An age was coming to an end.

I had studied the signs half-innocently in my classes, there had even been dire hints from a few perceptive professors, but I had never thought the situation would affect me personally… Until now.

I had been voided from the University of Mars , Sinai. Two hundred classmates and professors in the same predicament lined the brilliant white floor of the depot, faces crossed by shadows from sun shining through the webwork of beams and girders supporting the depot canopy. We were waiting for the Soils Dorsa train to come and swift us away to our planums, planitias, fossas, and valleys.

Diane Johara, my roommate, stood with her booted foot on one small bag, tapping the tip of the boot on the handle, lips pursed as if whistling but making no sound. She kept her face pointed toward the northern curtains, waiting for the train to nose through. Though we were good friends, Diane and I had never talked politics. That was basic etiquette on Mars.

“Assassination,” she said.

“Impractical,” I murmured. I had not known until a few days ago how strongly Diane felt. “Besides, who would you shoot?”

“The governor. The chancellor. ”

I shook my head.

Over eighty percent of the UMS students had been voided, a gross violation of contract. That struck me as very damned unfair, but my family had never been activist. Daughter of BM finance people, born to a long tradition of caution, I straddled the fence.
