Green Mars m-2

  “Oh, I wouldn’t tell anyone.”

  Maya laughed again.

  Michel said, “It’s a matter that is too important for us to trust a stranger. And you might not be able to keep it a secret. You would have to explain.how you had gotten so far from your vehicle.”

  “You could take me back to it.”

  “We don’t like to spend time around things like that. We wouldn’t have come close to it if we hadn’t noticed you were in trouble.”

  “Well, I appreciate it, but I must say this isn’t much of a rescue.”

  “Better than the alternative,” Maya told him sharply,

  “Very true. And I do appreciate it, really. But I promise I won’t tell anyone. And you know it isn’t as if people don’t know you’re out here. TV back home has shows about you all the time.”

  Even Maya was silenced by that. They drove on, Maya got on their intercom and had a brief rapid exchange with Coyote, who was traveling in the rover ahead of them, with Kasei and Nirgal. Coyote was adamant; as they had saved the man’s life, they could certainly rearrange it for a time to keep themselves out of danger. Michel reported the gist of the exchange to their prisoner.

  Randolph frowned briefly, then shrugged. Michel had never seen a faster adjustment to the rerouting of a life; the man’s sangfroid was impressive. Michel regarded him attentively, while also keeping one eye on the front camera screen. Randolph was already asking questions again, about the rover’s controls. He only made one more reference to his situation, after looking at the radio and intercom controls. “I hope you’ll let me send some kind of message to my company, so they’ll know I’m safe. I worked for Dumpmines, a part of Praxis. You and Praxis have a lot in common, really. They can be very secretive too. You ought to contact them just for your own sake, I swear. You must have some coded bands that you use, right?”

  No response from Maya or Michel. And later, when Randolph had gone into the rover’s little toilet chamber, Maya hissed, “He’s obviously a spy. He was out there deliberately so we would pick him up.”

  That was Maya. Michel did not try to argue with her, but only shrugged. “We’re certainly treating him like one.”

  And then he was back out among them, and asking more questions. Where did they live? What was it like hiding all the time? Michel began to be amused at what seemed more and more like a performance, or even a test; Randolph appeared perfectly open, ingenuous, friendly, his swarthy face almost that of a moon-calf simpleton — and yet his eyes watched them very carefully, and with every unanswered question he looked more interested and more pleased, as if their answers were coming to him by telepathy. Every human was a great power, every human on Mars an alchemist; and though Michel had given up psychiatry a long time ago, he could still recognize the touch of a master at work. He almost laughed at the growing urge he felt in himself, to confess everything to this hulking quizzical man, still clumsy in the Martian g.

  Then their radio beeped, and a compresed message lasting no more than two seconds buzzed over the speakers. “See,” Randolph said helpfully, “you could get a message out to Praxis just like that.”

  But when the AI finished running the message through the decryption sequence, there was no more joking. Sax had been arrested in Burroughs.

  At dawn they drew up with Coyote’s car, and spent the day conferring about what to do. They sat in a cramped circle in the living compartment, their faces all lined and etched with worry — all except their prisoner, who sat between Nirgal and Maya. Nirgal had shaken hands with him and nodded as if they were old friends, although neither had said a word. But the language of friendship was not in words.

  The news about Sax had come from Spencer, by way of Nadia. Spencer was working in Kasei Vallis, which was a kind of new Korolyov, a security town, very sophisticated and at the same time very low-profile. Sax had been taken to one of the compounds

  there, and Spencer had found out about it and made the call out to Nadia.

  “We have to get him out,” Maya said, “and fast. They’ve only had him a couple days.”

  “The Sax Russell?” Randolph was saying. “Wow. I can’t believe it. Who are you all, anyway? Hey, are you Maya Toitovna?”

  Maya cursed him in livid Russian. Coyote ignored them all; he hadn’t said anything since the message had arrived, and was busy at his AI screen, looking at what appeared to be weather satellite photos.

  “You might as well let me go,” Randolph said into the silence. “I couldn’t tell them anything they won’t get out of Russell.”

  “He won’t tell them anything!” Kasei said hotly.

  Randolph waggled a hand. “Scare him, maybe hurt him a little, put him under, plug him in, dope him up and zap his brain in the right places — they’ll get answers to whatever they ask. They’ve got it down to a science, as I understand it.” He was staring at Kasei. “You look familiar too. Never mind! Anyway, if they can’t tweak it out, they can usually do it more crudely.”

  “How do you know all this?” Maya demanded.

  “Common knowledge,” Randolph said. “So maybe it’s all wrong, but…”

  “I want to go get him,” Coyote said.

  “But they’ll know we’re out here,” Kasei said.

  “They know that anyway. What they don’t know is where we are.”

  “Besides,” Michel said, “it’s our Sax.”

  Coyote said, “Hiroko won’t object.”

  “If she does, tell her to fuck off!” Maya exclaimed. “Tell her shikata ga nai!”

  “It would be my pleasure,” Coyote said.

  The western and northern slopes of the Tharsis bulge were unpopulated relative to the eastern drop to Noctis Labyrinthus; there were a few areothermal stations and aquifer wells, but much of the region was covered in a year-round blanket of snow and fim and young glaciers. Winds out of the south collided with the strong northwest winds coming around Olympus Mons, and the blizzards could be fierce. The protoglacial zone extended up from the six-or seven-kilometer contour nearly to the base of the great volcanoes; it was not a good place to build, nor was it a good place for stealth cars to hide. They drove hard over the sastrugi and along ropy lava mounds that served as roads, north past the bulk of Tharsis Tholus, a volcano that was about the size of Mauna Loa, though under the rise of Ascraeus it looked like a cinder cone. The next night they made it off the snow and northeast across Echus Chasma, and hid for the day under the stupendous eastern wall of Echus, just a few kilometers north of Sax’s old headquarters at the top of the cliff.

  The east wall of Echus Chasma was the Great Escarpment at its absolute greatest — a cliff three kilometers tall, running in a straight line north and south for a thousand kilometers. The areologists were still arguing over its origin, as no ordinary force of landscape formation seemed adequate to have created it. It was simply a break in the fabric of things, separating the floor of Echus Chasma from the high plateau of Lunae Planum. Michel had visited Yosemite Valley in his youth, and he still recalled those towering granite cliffs; but this wall standing before them was as long as the whole state of California, and three kilometers high for most of that length: a vertical world, its massive planes of redrock staring out blankly to the west, glowing in each empty sunset like the side of a continent.

  At its northern end this incredible cliff finally became less tall, and less steep, and just above 20° North it was cut by a deep broad channel, which ran east through Lunae plateau, down onto the Chryse basin. This big canyon was Kasei Vallis, one of the clearest manifestations of ancient flooding anywhere on Mars. A single glance at a satellite photo and it was obvious that a very large flood had run down Echus Chasma once upon a time, until it reached a break in its great eastern wall, perhaps a graben. The water had turned right down this valley and smashed through it with fantastic force, eroding the entrance until it was a smooth curve, slopping over the outside bank of the turn and ripping at joints in the rock until they were a complex gridwork of narrow canyons. A central r
idge in the main valley had been shaped into a long lemniscate or tear-shaped island, the shape as hydrodynamic as a fishback. The inner bank of the fossil watercourse was incised by two canyons that had been mostly untouched by water, ordinary fossae that showed what the main channel had probably looked like before the flood. Two late meteor strikes on the highest part of the inner bank had completed the shaping of the terrain, leaving fresh steep craters.

  From the ground, driving slowly onto the rise of the outer bank, it was a rounded elbow of a valley, with the lemniscate ridge, and the round ramparts of the craters on the rise of the inner bank, the most prominent features. It was an attractive landscape, reminiscent of the Burroughs region in its spatial majesty, the great sweep of the main channel just begging to be filled with running water, which no doubt would be a shallow braided stream, coursing over pebbles and cutting new beds and islands every week…

  But now it was the site for the transnationals’ security compound. The two craters on the inner bank had been tented, as had big sections of the gridwork terrain on the outer bank, and part of the main channel on both sides of the lemniscate island; but none of this work was ever shown on the video, or mentioned in the news. It was not even on the maps.

  Spencer had been there since the beginning of construction, however, and his infrequent reports out had told them what the new town was for. These days almost all the people found guilty of crimes on Mars were sent out to the asteroid belt, to work off their sentences in mining ships. But there were people in the Transitional Authority who wanted a jail on Mars itself, and Kasei Vallis was it.

  Outside the valley entrance they hid their boulder cars in a knot of boulders, and Coyote studied weather reports. Maya fumed at the delay, but Coyote shrugged her off. “This isn’t going to be easy,” he told her sternly, “and it isn’t possible at all except in certain circumstances. We need to wait for some reinforcements to arrive, and we need to wait on the weather. This is something Spencer and Sax himself helped me to set up, and it is very clever, but the initial conditions have to be right.”

  He returned to his screens, ignoring them all, talking to himself or to the screens, his dark thin face flickering in their light. Alchemist indeed, Michel thought, muttering as if over alembic or crucible, working his transmutations on the planet… a great power. And now focused on the weather. Apparently he had discovered some prevailing patterns in the jet stream, tied to certain anchoring points in the landscape. “It’s a question of the vertical scale,” he said brusquely to Maya, who with all her questions was beginning to sound like Art Randolph. “This planet has a thirty-k span top to bottom. Thirty thousand meters! So there are strong winds.”

  “Like the mistral,” Michel offered.

  “Yes. Katabatic winds. And one of the strongest of them drops off the Great Escarpment here.”

  The prevailing winds in the region, however, were westerlies. When these hit the Echus cliff, towering updrafts resulted, and flyers living in Echus Overlook took advantage of them for sport, flying all day in gliders or birdsuits. But fairly frequently cyclonic systems came by, bringing winds from the east, and when that happened cold air ran over the snow-covered Lunae plateau, scouring snow and becoming denser and colder, until the entire drainage area was funneled out through notches in the great cliffs edge, and the winds then fell like an avalanche.

  Coyote had studied these katabatic winds for some time, and his calculations had led him to believe that when conditions were right — sharp temperature contrasts, a developed storm track east to west across the plateau — then very slight interventions in certain places would cause the downdrafts to turn into vertical typhoons, smashing down into Echus Chasma and blasting north and south with immense power. When Spencer had identified for them the nature and purpose of the new settlement in Kasei Vallis, Coyote had immediately decided to try to create the means to effect these interventions.

  “Those idiots built their prison in a wind tunnel,” he muttered at one point, in answer to Maya’s inquisition. “So we built a fan. Or rather a switch to turn the fan on. We dug in some silver nitrate dispensers at the top of the cliff. Big monster jet hoses. Then some lasers to burn the air just over the flow zone. That creates an unfavorable pressure gradient, damming up the normal outflow so that it’s stronger when it finally breaks through. And explosives installed all down the cliff face, to push dust into the wind and make it heavier. See, wind heats up as it falls, and that would slow it down some if it weren’t so full of snow and dust. I climbed down that cliff five times to set it all up, you should have seen it. Set some fans as well. Of course the power of the whole apparatus is negligible compared to the total wind force, but sensitive dependence is the whole key to weather, you see, and our computer modeling located the spots to push the initial conditions the way we want. Or so we hope.”

  “You haven’t tried it?” Maya asked.

  Coyote stared at her. “We tried it in the computer. It works fine. If we get initial conditions of hundred-and-fifty kilometer cyclonic winds over Lunae, you’ll see.”

  “They must know about these katabatic winds in Kasei,” Randolph pointed out.

  “They do. But what they calculated as once-a-millennium winds, we think we can create any time the initial conditions are there on top.”

  “Guerrilla climatology,” Randolph said, eyes bugged out. “What do you call that, climatage? Attack meteorology?”

  Coyote pretended to ignore him, although Michel saw a brief grin through the dreadlocks.

  But his system would only work with the proper initial conditions. There was nothing to do but sit and wait, and hope they developed.

  During these long hours it seemed to Michel that Coyote was trying to project himself through his screen, out into the sky. “Come on,” the wiry little man urged under his breath, nose against glass. “Push, push, push. Come over that hill, you bastard wind. Tuck and turn, spiral tight. Come on!”

  He wandered the darkened car when the rest of them were trying to sleep, muttering, “Look, yes, look,” and pointing at features of satellite photos that none of the rest of them could see. He sat brooding over scrolling meteorological data, chewing on bread and cursing, whistling like a wind. Michel lay on his narrow cot, head propped on his hand, watching in fascination as the wild man prowled through the dimness of the car, a small, shadowy, secretive, shamanesque figure. And the bearish lump of their prisoner, one eye agleam, was likewise awake to witness this nocturnal scene, rubbing his scruffy jaw with an audible rasping, glancing at Michel as the whispering continued. “Come on, damn you, come on. Shoooooooooo … Blow like an October hurricane …”

  Finally, at sunset on their second day of waiting, Coyote stood and stretched like a cat. “The winds have come.”

  During the long wait some Reds had driven from Mareotis to aid in the rescue, and Coyote had worked out a plan of attack with them, based on information Spencer had sent out. They were going to split up, and come on the town from several angles. Michel and Maya were to drive one car onto the cracked terrain of the outer bank, where they could hide at the foot of a small mesa within sight of the outer-bank tents. One of these tents contained a medical clinic where Sax was being taken some of the time, a fairly low-security place according to Spencer, at least compared to the holding compound on the inner bank, where Sax was being kept between sessions in the clinic. His schedule was staggered, and Spencer could not be sure which location he would be in at any given time. So when the wind hit, Michel and Maya were going to enter the outer-bank tent and meet Spencer, who would be there ready to guide them to the clinic. The bigger car, with Coyote, Kasei, Nirgal, and Art Randolph, was going to converge, with some of the Reds from Mareotis, on the inner bank. Other Red cars would be doing their best to make the raid look like a full-scale attack from all directions, particularly the east. “We will make the rescue,” Coyote said, frowning at his screens. “The wind will make the attack.”

  So the next morning Maya and Michel sat in t
heir car, waiting for the winds to arrive. They had a view down the slope of the outer bank to the big lemniscate ridge. Through the day they could see into the green bubble worlds under the tents on the outer bank and the ridge — little terrariums, overlooking the red sandy sweep of the valley, connected by clear transit tubes and one or two arching bridge tubes. It looked like Burroughs some forty years before, patches of a city growing to fill a big desert arroyo.

  Michel and Maya slept; ate; sat; watched. Maya paced the car. She had been getting more nervous every day, and now she padded about like a caged tigress that has smelled the blood of a meal. Static electricity jumped off her fingertips as she caressed Michel’s neck, making her touch painful. It was impossible to calm her down; Michel stood behind her when she sat in the pilot’s chair, massaging her neck and shoulders as she had his, but it was like trying to knead blocks of wood, and he could feel his arms getting tense from the contact.

  Their talk was disconnected and desultory, wandering in random jumps of free association. In the afternoon they found themselves talking for an hour about the days in Underhill — about Sax, and Hiroko, and even Frank and John.

  “Do you remember when one of the vaulted chambers collapsed?”

  “No,” she said irritably. “I don’t. Do you remember the time Ann and Sax had that big argument about the terraforming?”

  “No,” Michel said with a sigh, “I can’t say I do.” They could go back and forth like that for a long time, until it seemed they had lived in completely different Underhills. When they both remembered an event, it was cause for cheer. All the First Hundred’s memories were growing spotty, Michel had noticed, and it seemed to him that most of them recalled their childhoods on Earth better than they did their first years on Mars. Oh, they remembered their own biggest events, and the general shape of the story; but the little incidents that somehow stuck in mind were different for everyone. Memory retention and recollection were getting to be big clinical and theoretical problems in psychology, exacerbated by the unprecedented longevities now being achieved. Michel had read some of the literature on it from time to time, and though he had long ago given up the clinical practice of therapy, he still asked questions of his old comrades in a kind of informal experiment, as he did now with Maya: Do you remember this, do you remember that? No, no, no. What do you remember?
