Blue Mars - Kim Stanley Robinson [32]
The soil berm was dotted by pale green rosettes of tiny grass blades. Longer blades stood in clumps here and there. Most of the taller blades were dead, and light gray. Right next to the pond were patches of dark green succulent leaves, dark red at their edges. Where the green shaded into red was a color he couldn’t name, a dark lustrous brown stuffed somehow with both its constituent colors. He would have to call up a color chart soon, it seemed; lately when looking around outdoors he found that a color chart came in handy about once a minute. Waxy almost-white flowers were tucked under some of these bicolored leaves. Farther on lay some tangles, red-stalked, green-needled, like beached seaweed in miniature. Again that intermixture of red and green, right there in nature staring at him.
A distant wind-washed hum; perhaps the harping rocks, perhaps the buzz of insects. Black midges, bees . . . in this air they would only have to sustain about thirty millibars of CO2, because there was so little partial pressure driving it into them, and at some point internal saturation was enough to hold any more out. For mammals that might not work so well. But they might be able to sustain twenty millibars, and with plant life flourishing all over the planet’s lower elevations, CO2 levels might drop to twenty millibars fairly soon; and then they could dispense with the air tanks and the face masks. Set loose animals on Mars.
In the faint hum of the air he seemed to hear their voices, immanent or emergent, coming in the next great surge of viriditas. The hum of distant voices; the wind; the peace of this little pool on its rocky moor; the Nirgalish pleasure he took in the sharp cold. . . . “Ann should see this,” he murmured.
Then again, with the space mirrors gone, presumably everything he saw here was doomed. This was the upper limit of the biosphere, and surely with the loss of light and heat the upper limit would drop, at least temporarily, perhaps for good. He didn’t like that; and it seemed possible there might be ways to compensate for the lost light. After all, the terraforming had been doing quite well before the mirrors’ arrival; they hadn’t been necessary. And it was good not to depend on something so fragile, and better to be rid of it now rather than later, when large animal populations might have died in the setback along with the plants.
Even so it was a shame. But the dead plant matter would only be more fertilizer in the end, and without the same kind of suffering as animals. At least so he assumed. Who knew how plants felt? When you looked closely at them, glowing in all their detailed articulation like complex crystals, they were as mysterious as any other life. And now their presence here made the entire plain, everything he could see, into one great fellfield, spreading in a slow tapestry over the rock; breaking down the weathered minerals, melding with them to make the first soils. A very slow process. There was a vast complexity in every pinch of soil; and the look of this fellfield was the loveliest thing he had ever seen.

To weather. This whole world was weathering. The first printed use of the word with that meaning had appeared in a book on Stonehenge, appropriately enough, in 1665. “The weathering of so many Centuries of Years.” On this stone world. Weathering. Language as the first science, exact yet vague, or multivalent. Throwing things together. The mind as weather. Or being weathered.
There were clouds coming up over the nearby hillocks to the west, their bottoms resting on a thermal layer as levelly as if pressing down on glass. Streamers like spun wool led the way east.
Sax stood up and climbed out of the pool’s depression. Out of the shelter of the hole, the wind was shockingly strong— in it the cold intensified as if an ice age had struck full force that very second. Windchill factor, of course; if the temperature was 262 K, and the wind was blowing at about seventy kilometers an hour, with gusts much stronger, then the windchill factor would create a temperature equivalent of about 250
