Blue Mars Part 6

So he went back to Pavonis, leaving the group in Sabis.h.i.+ talking things over.

Back on Pavonis everything was the same. More and more people, spurred on by Art Randolph, were proposing that they hold a const.i.tutional congress. Write an at least provisional const.i.tution, hold a vote on it, then establish the government described.

"Good idea," Sax said. "Perhaps a delegation to Earth as well."

Casting seeds. It was just like on the moors; some would sprout, others wouldn't.

He went looking for Ann, but found she had left Pavonis- gone, people said, to a Red outpost in Tempe Terra, north of Tharsis. No one went there but Reds, they said.

After some thought Sax asked for Steve's help, and looked up the outpost's location. Then he borrowed a little plane from the Bogdanovists and flew north, past Ascraeus Mons on his left, then down Echus Chasma, and past his old headquarters at Echus Overlook, on top of the huge wall to his right.

Ann too had no doubt flown this route, and thus gone by the first headquarters of the terraforming effort. Terraforming... there was evolution in everything, even in ideas. Had Ann noticed Echus Overlook, had she even remembered that small beginning? No way of telling. That was how humans knew each other. Tiny fractions of their lives intersected or were known in any way to anybody else. It was much like living alone in the universe. Which was strange. A justification for living with friends, for marrying, for sharing rooms and lives as much as possible. Not that this made people truly intimate; but it reduced the sensation of solitude. So that one was still sailing solo through the oceans of the world, as in Mary Sh.e.l.ley's The Last Man The Last Man, a book that had much impressed Sax as a youth, in which the eponymous hero at the conclusion occasionally saw a sail, joined another s.h.i.+p, anch.o.r.ed against a sh.o.r.e, shared a meal- then voyaged on, alone and solitary. An image of their lives; for every world was as empty as the one Mary Sh.e.l.ley had imagined, as empty as Mars had been in the beginning.

He flew past the blackened curve of Kasei Vallis without noting it at all.

The Reds had long ago hollowed out a rock the size of a city block, in a promontory that served as the last dividing wedge in the intersection of two of the Tempe Fossa, just south of Perepelkin Crater. Windows under overhangs gave them a view over both of the bare straight canyons, and the larger canyon they made after their confluence. Now all these fossae cut down what had become a coastal plateau; Mareotis and Tempe together formed a huge peninsula of ancient highlands, sticking far into the new ice sea.

Sax landed his little plane on the sandy strip on top of the promontory. From here the ice plains were not visible; nor could he spot any vegetation- not a tree, not a flower, not even a patch of lichen. He wondered if they had somehow sterilized the canyons. Just primal rock, with a dusting of frost. And nothing they could do about frost, unless they wanted to tent these canyons, to keep air out rather than in. "Hmm," Sax said, startled at the idea.

Two Reds let him in the lock door on the top of the promontory, and he descended stairs with them. The shelter appeared to be nearly empty. Just as well. It was nice only to have to withstand the cold gazes of two young women leading him through the rough-hewn rock galleries of the refuge, rather than a whole gang. Interesting to see Red aesthetics. Very spare, as might be expected- not a plant to be seen- just different textures of rock: rough walls, rougher ceilings, contrasted to a polished basalt floor, and the glistening windows overlooking the canyons.

They came to a cliffside gallery that looked like a natural cave, no straighter than the nearly Euclidean lines of the canyon below. There were mosaics inlaid into the back wall, made of bits of colored stone, polished and set against each other without gaps, forming abstract patterns that seemed almost to represent something, if only he could focus properly on them. The floor was a stone parquet of onyx and alabaster, serpentine and bloodstone. The gallery went on and on- big, dusty- the whole complex somewhat disused, perhaps. Reds preferred their rovers, and places like this no doubt had been seen as unfortunate necessities. Hidden refuge; with windows shuttered, one could have walked down the canyons right past the place and not known it was there; and Sax felt that this was not just to avoid the notice of the UNTA, but also to be un.o.btrusive before the land itself, to melt into it.

As Ann seemed to be trying to do, there in a stone window seat. Sax stopped abruptly; lost in his thoughts, he had almost run into her, just as an ignorant traveler might have run into the shelter. A chunk of rock, sitting there. He looked at her closely. She looked ill. One didn't see that much anymore, and the longer Sax looked at her, the more alarmed he became. She had told him, once, that she was no longer taking the longevity treatment. That had been some years before. And during the revolution she had burned like a flame. Now, with the Red rebellion quelled, she was ash. Gray flesh. It was an awful sight. She was somewhere around 150 years old, like all the First Hundred left alive, and without the treatments... she would soon die.

Well. Strictly speaking, she was at the physiological equivalent of being seventy or so, depending on when she had last had the treatments. So not that bad. Perhaps Peter would know. But the longer one went between treatments, he had heard, the more problems cropped up, statistically speaking. It made sense. It was only wise to be prudent.

But he couldn't say that to her. In fact, it was hard to think what he could say to her.

Eventually her gaze lifted. She recognized him and shuddered, her lip lifting like a trapped animal's. Then she looked away from him, grim, stone-faced. Beyond anger, beyond hope.

"I wanted to show you some of the Tyrrhena ma.s.sif," he said lamely.

She got up like a statue rising, and left the room.

Sax, feeling his joints creak with the pseudo-arthritic pain that so often accompanied his dealings with Ann, followed her.

He was trailed in his turn by the two stern-looking young women. "I don't think she wants to talk to you," the taller one informed him.

"Very astute of you," Sax said.

Far down the gallery, Ann was standing before another window: spellbound, or else too exhausted to move. Or part of her did want to talk.

Sax stopped before her.

"I want to get your impressions of it," he said. "Your suggestions for what we might do next. And I have some, some, some areological questions. Of course it could be that strictly scientific questions aren't of interest to you anymore-"

She took a step toward him and struck him on the side of the face. He found himself slumped against the gallery wall, sitting on his b.u.t.t. Ann was nowhere to be seen. He was being helped to his feet by the two young women, who clearly didn't know whether to cheer or groan. His whole body hurt, more even than his face, and his eyes were very hot, stinging slightly. It seemed he might cry before these two young idiots, who by trailing him were complicating everything enormously; with them around he could not yell or plead, he could not go on his knees and say Ann, please, forgive me. He couldn't.

"Where did she go?" he managed to say.

"She really, really really doesn't want to talk to you," the tall one declared. doesn't want to talk to you," the tall one declared.

"Maybe you should wait and try later," the other advised.

"Oh shut up!" Sax said, suddenly feeling an irritation so vehement that it was like rage. "I suppose you would just let her stop taking the treatment and kill herself!"

"It's her right," the tall one pontificated.

"Of course it is. I wasn't speaking of rights. I was speaking of how a friend should behave when someone is suicidal. Not a subject you are likely to know anything about. Now help me find her."

"You're no friend of hers."

"I most certainly am." He was on his feet. He staggered a little as he tried to walk in the direction he thought she had gone. One of the young women tried to take his elbow. He avoided the help and went on. There Ann was, in the distance, collapsed in a chair, in some kind of dining chamber, it seemed. He approached her, slowing like Apollo in Zeno's paradox.

She swiveled and glared at him.

"It's you you who abandoned science, right from the start," she snarled. "So don't you give me that s.h.i.+t about not being interested in science!" who abandoned science, right from the start," she snarled. "So don't you give me that s.h.i.+t about not being interested in science!"

"True," Sax said. "It's true." He held out both hands. "But now I need advice. Scientific advice. I want to learn. And I want to show you some things as well."

But after a moment's consideration she was up and off again, right past him, so that he flinched despite himself. He hurried after her; her gait was much longer than his, and she was moving fast, so that he had to almost jog. His bones hurt.

"Perhaps we could go out here," Sax suggested. "It doesn't matter where we go out."

"Because the whole planet is wrecked," she muttered.

"You must still go out for sunsets occasionally," Sax persisted. "I could join you for that, perhaps."

"No."

"Please, Ann." She was a fast walker, and enough taller than him that it was hard to keep up with her and talk as well. He was huffing and puffing, and his cheek still hurt. "Please, Ann."

She did not answer, she did not slow down. Now they were walking down a hall between suites of living quarters, and Ann sped up to go through a doorway and slam the door behind her. Sax tried it; it was locked.

Not, on the whole, a promising beginning.

Hound and hind. Somehow he had to change things so that it was not a hunt, a pursuit. Nevertheless: "I huff, I puff, I blow your house down," he muttered. He blew at the door. But then the two young women were there, staring hard at him.

One evening later that week, near sunset, he went down to the changing room and suited up. When Ann came in he jumped several centimeters. "I was just going out?" he stammered. "Is that okay with you?"

"It's a free country," she said heavily.

And they went out the lock together, into the land. The young women would have been amazed.

He had to be very careful. Naturally, although he was out there with her to show to her the beauty of the new biosphere, it would not do to mention plants, or snow, or clouds. One had to let things speak for themselves. This was perhaps true of all phenomena. Nothing could be spoken for. One could only walk over the land, and let it speak for itself.

Ann was not gregarious. She barely spoke to him. It was her usual route, he suspected as he followed her. He was being allowed to come along.

It was perhaps permissible to ask questions: this was science. And Ann stopped often enough, to look at rock formations up close. It made sense at those times to crouch beside her, and with a gesture or a word ask what she was finding. They wore suits and helmets, even though the alt.i.tude was low enough to have allowed breathing with only the aid of a CO2 filter mask. Thus conversations consisted of voices in the ear, as of old. Asking questions.

So he asked. And Ann would answer, sometimes in some detail. Tempe Terra was indeed the Land of Time, its bas.e.m.e.nt material a surviving piece of the southern highlands, one of those lobes of it that stuck far into the northern plains- a survivor of the Big Hit. Then later Tempe had fractured extensively, as the lithosphere was pushed up from below by the Tharsis Bulge to the south. These fractures included both the Mareotis Fossae and the Tempe Fossa surrounding them now.

The spreading land had cracked enough to allow some latecomer volcanoes to emerge, spilling over the canyons. From one high ridge they saw a distant volcano like a black cone dropped from the sky; then another, looking just like a meteor crater as far as Sax could see. Ann shook her head at this observation, and pointed out lava flows and vents, features all visible once they were pointed out, but not at all obvious under a scree of later ejecta rubble and (one had to admit it) a dusting of dirty snow, collecting like sand drifts in wind shelters, turning sand-colored in the sunset light.

To see the landscape in its history, to read it like a text, written by its own long past; that was Ann's vision, achieved by a century's close observation and study, and by her own native gift, her love for it. Something to behold, really- something to marvel at. A kind of resource, or treasure- a love beyond science, or something into the realm of Michel's mystical science. Alchemy. But alchemists wanted to change things. A kind of oracle, rather. A visionary, with a vision just as powerful as Hiroko's, really. Less obviously visionary, perhaps, less spectacular, less active; an acceptance of what was there; love of rock, for rock's sake. For Mars's sake. The primal planet, in all its sublime glory, red and rust, still as death; dead; altered through the years only by matter's chemical permutations, the immense slow life of geophysics. It was an odd concept- abiologic life- but there it was, if one cared to see it, a kind of living, out there spinning, moving through the stars that burned, moving through the universe in its great systolic/diastolic movement, its one big breath, one might say. Sunset somehow made it easier to see that.

Trying to see things Ann's way. Glancing furtively at his wristpad, behind her back. Stone, from Old English stan stan, cognates everywhere, back to proto-Indo-European sti sti, a pebble. Rock, from medieval Latin rocca rocca, origin unknown; a ma.s.s of stone. Sax abandoned the wristpad and fell away into a kind of rock reverie, open and blank. Tabula rasa, to the point where apparently he did not hear what Ann herself was saying to him; for she snorted and walked on. Abashed, he followed, and steeled himself to ignore her displeasure, and ask more questions.

There seemed to be a lot of displeasure in Ann. In a way this was rea.s.suring; lack of affect would have been a very bad sign; but she still seemed quite emotional. At least most of the time. Sometimes she focused on the rock so intently it was almost like watching her obsessed enthusiasm of old, and he was encouraged; other times it seemed she was just going through the motions, doing areology in a desperate attempt to stave off the present moment; stave off history; or despair; or all of that. In those moments she was aimless, and did not stop to look at obviously interesting features they pa.s.sed, and did not answer his questions about same. The little Sax had read about depression alarmed him; not much could be done, one needed drugs to combat it, and even then nothing was sure. But to suggest antidepressants was more or less the same as suggesting the treatment itself; and so he could not speak of it. And besides, was despair the same as depression?

Happily, in this context, plants were pitifully few. Tempe was not like Tyrrhena, or even the banks of the Arena Glacier. Without active gardening, this was what one got. The world was still mostly rock.

On the other hand, Tempe was low in alt.i.tude, and humid, with the ice ocean just a few kilometers to the north and west. And various Johnny Appleseed flights had pa.s.sed over the entire southern sh.o.r.eline of the new sea- part of Biotique's efforts, begun some decades ago, when Sax had been in Burroughs. So there was some lichen to be seen, if you looked hard. And small patches of fellfield. And a few krummholz trees, half-buried in snow. All these plants were in trouble in this northern summer-turned-winter, except for the lichen of course. There was a fair bit of miniaturized fall color already, there in the tiny leaves of the ground-hugging koenigia, and pygmy b.u.t.tercup, and icegra.s.s, and, yes, arctic saxifrage. The reddening leaves served as a kind of camouflage in the ambient redrock; often Sax didn't see plants until he was about to step on them. And of course he didn't want to draw Ann's attention to them anyway, so when he did stumble on one, he gave it a quick evaluative glance and walked on.

They climbed a prominent knoll overlooking the canyon west of the refuge, and there it was: the great ice sea, all orange and bra.s.s in the late light. It filled the lowland in a great sweep and formed its own smooth horizon, from southwest to northeast. Mesas of the fretted terrain now stuck out of the ice like sea stacks or cliff-sided islands. In truth this part of Tempe was going to be one of the most dramatic coastlines on Mars, with the lower ends of some fossae filling to become long fjords or lochs. And one coastal crater was right at sea level, and had a break in its sea side, making it a perfect round bay some fifteen kilometers across, with an entry channel about two kilometers across. Farther south, the fretted terrain at the foot of the Great Escarpment would create a veritable Hebrides of an archipelago, many of the islands visible from the cliffs of the mainland. Yes, a dramatic coastline. As one could see already, looking at the broken sheets of sunset ice.

But of course this was not to be noted. No mention at all of the ice, the jagged bergs jumbled on the new sh.o.r.eline. The bergs had been formed by some process Sax wasn't aware of, though he was curious- but it could not be discussed. One could only stand in silence, as if having stumbled into a cemetery.

Embarra.s.sed, Sax knelt to look at a specimen of Tibetan rhubarb he had almost stepped on. Little red leaves, in a floret from a central red bulb.

Ann was looking over his shoulder. "Is it dead?"

"No." He pulled off a few dead leaves from the exterior of the floret, showed her the brighter ones beneath. "It's hardening for the winter already. Fooled by the drop in light." Then Sax went on, as if to himself: "A lot of the plants will die, though. The thermal overturn," which was when air temperatures turned colder than the ground temperatures, "came more or less overnight. There won't be much chance for hardening. Thus lots of winterkill. Plants are better at handling it than animals would have been. And insects are surprisingly good, considering they're little containers of liquid. They have supercooling cryoprotectants. They can stand whatever happens, I think."

Ann was still inspecting the plant, and so Sax shut up. It's alive, he wanted to say. Insofar as the members of a biosphere depend on each other for existence, it is part of your body. How can you hate it?

But then again, she wasn't taking the treatment.

The ice sea was a shattered blaze of bronze and coral. The sun was setting, they would have to get back. Ann straightened and walked away, a black silhouette, silent. He could speak in her ear, even now when she was a hundred meters away, then two hundred, a small black figure in the great sweep of the world. He did not; it would have been an invasion of her privacy, almost of her thoughts. But how he wondered what those thoughts were. How he longed to say Ann, Ann, what are you thinking? Talk to me, Ann. Share your thoughts.

The intense desire to talk with someone, sharp as any pain; this was what people meant when they talked about love. Or rather; this was what Sax would acknowledge to be love. Just the super-heightened desire to share thoughts. That alone. Oh Ann, please talk to me.

But she did not talk to him. On her the plants seemed not to have had the effect they had had on him. She seemed truly to abominate them, these little emblems of her body, as if viriditas were no more than a cancer that the rock must suffer. Even though in the growing piles of wind-drifted snow, plants were scarcely visible anymore. It was getting dark, another storm was sweeping in, low over the black-and-copper sea. A pad of moss, a lichened rockface; mostly it was rock alone, just as it had ever been. Nevertheless.

Then as they were getting back into the refuge lock, Ann fell in a faint. On the way down she hit her head on the doorjamb. Sax caught her body as she was landing on a bench against the inner wall. She was unconscious, and Sax half carried her, half dragged her all the way into the lock. Then he pulled the outer door shut, and when the lock was pumped, pulled her through the inner door into the changing room. He must have been shouting over the common band, because by the time he got her helmet off, five or six Reds were there in the room, more than he had seen in the refuge so far. One of the young women who had so impeded him, the short one, turned out to be the medical person of the station, and when they got Ann up onto a rolling table that could be used as a gurney, this woman led the way to the refuge's medical clinic, and there took over. Sax helped where he could, getting Ann's walker boots off her long feet with shaking hands. His pulse rate- he checked his wrist-pad- was 145 beats a minute- and he felt hot, even lightheaded.

"Has she had a stroke?" he said. "Has she had a stroke?"

The short woman looked surprised. "I don't think so. She fainted. Then struck her head."

"But why did she faint?"

"I don't know."

She looked at the tall young woman, who sat next to the door. Sax understood that they were the senior authorities in the refuge. "Ann left instructions for us not to put her on any kind of life-support mechanism, if she were ever incapacitated like this."

"No," Sax said.

"Very explicit instructions. She forbade it. She wrote it down."

"You put her on whatever it takes to keep her alive," Sax said, his voice harsh with strain. Everything he had said since Ann's collapse had been a surprise to him; he was a witness to his actions just as much as they were. He heard himself say, "It doesn't mean you have to keep her on it, if she doesn't come around. It's just a reasonable minimum, to make sure she doesn't go for nothing."

The doctor rolled her eyes at this distinction, but the tall woman sitting in the doorway looked thoughtful.

Sax heard himself go on: "I was on life support for some four days, as I understand it, and I'm glad no one decided to turn it off. It's her decision, not yours. Anyone who wants to die can do it without having to make a doctor compromise her Hippocratic oath."

The doctor rolled her eyes even more disgustedly than before. But with a glance at her colleague, she began to pull Ann onto the life-support bed; Sax helped her; and then she was turning on the medical AI, and getting Ann out of her walker. A rangy old woman, now breathing with an oxygen mask over her face. The tall woman stood and began to help the doctor, and Sax went and sat down. His own physiological symptoms were amazingly severe, marked chiefly by heat all through him, and a kind of incompetent hyperventilation; and an ache that made him want to cry.

After a time the doctor came over. Ann had fallen into a coma, she said. It looked like a small heart-rhythm abnormality had caused her to faint in the first place. She was stable at the moment.

Sax sat in the room. Much later the doctor returned. Ann's wristpad had recorded an episode of rapid irregular heartbeat, at the time she fainted. Now there was still a small arrhythmia. And apparently anoxia, or the blow to the head, or both, had initiated a coma.

Sax asked what exactly a coma was, and felt a sinking feeling when the doctor shrugged. It was a catchall term, apparently, for unconscious states of a certain kind. Pupils fixed, body insensitive, and sometimes locked into decorticate postures. Ann's left arm and leg were twisted. And unconsciousness of course. Sometimes odd vestiges of responsiveness, clenching hands and the like. Duration of coma varied widely. Some people never came out of them.

Sax looked at his hands until the doctor left him alone. He sat in the room until everyone else was gone. Then he got up and stood at Ann's side, looking down at her masked face. Nothing to be done. He held her hand; it did not clench. He held her head, as he had been told Nirgal had held his when he was unconscious. It felt like a useless gesture.

He went to the AI screen, and called up the diagnostic program. He called up Ann's medical data, and ran back the heart monitor data from the incident in the lock. A small arrhythmia, yes; rapid, irregular pattern. He fed the data into the diagnostic program, and looked up heart arrhythmia on his own. There were a lot of aberrant cardiac rhythm patterns, but it appeared that Ann might have a genetic predisposition to suffer from a disorder called long QT syndrome, named for a characteristic abnormal long wave in the electrocardiogram. He called up Ann's genome, and instructed the AI to run a search in the relevant regions of chromosomes 3, 7, and 11. In the gene called HERG, in her chromosome 7, the AI identified a small mutation: one reversal of adenine-thymine and guanine-cytosine. Small, but HERG contained instructions for the a.s.sembly of a protein that served as a pota.s.sium ion channel in the surface of heart cells, and these ion channels acted as a switch to turn off contracting heart cells. Without this brake the heart could go arrhythmic, and beat too fast to pump blood effectively.

Ann also appeared to have another problem, with a gene on chromosome 3 called SCN5A. This gene encoded a different regulatory protein, which provided a sodium ion channel on the surface of heart cells. This channel functioned as an accelerator, and mutations here could add to the problem of rapid heartbeat. Ann had a CG bit missing.

These genetic conditions were rare, but for the diagnostic AI that was not an issue. It contained a symptomology for all known problems, no matter how rare. It seemed to consider Ann's case to be fairly straightforward, and it listed the treatments that existed to counteract the problems presented by the condition. There were a lot of them.

One of the treatments suggested was the recoding of the problem genes, in the course of the standard gerontological treatments. Persistent gene recodings through several longevity treatments should erase the cause of the problem right at the root, or rather in the seed. It seemed strange that this hadn't been done already, but then Sax saw that the recommendation was only about two decades old; it came from a period after the last time Ann had taken the treatments.

For a long time Sax sat there, staring at the screen. Much later he got up. He began to inspect the Reds' medical clinic, instrument by instrument, room by room. The nursing attendants let him wander; they thought he was distraught.

This was a major Red refuge, and it seemed likely to him that one of the rooms might contain the equipment necessary to administer the gerontological treatments. Indeed it was so. A small room at the back of the clinic appeared to be devoted to the process. It didn't take much: a bulky AI, a small lab, the stock proteins and chemicals, the incubators, the MRIs, the IV equipment. Amazing, when you considered what it did. But that had always been true. Life itself was amazing: simple protein sequences only, at the start, and yet here they were.

So. The main AI had Ann's genome record. But if he ordered this lab to start synthesizing her DNA strands for her (adding the recodings of HERG and SCN5A) the people here would surely notice. And then there would be trouble.

He went back to his tiny room to make a coded call to Da Vinci. He asked his a.s.sociates there to start the synthesis, and they agreed without any questions beyond the technical ones. Sometimes he loved those saxaclones with all his heart.

After that it was back to waiting. Hours pa.s.sed; more hours; more hours. Eventually several days had pa.s.sed, with no change in Ann. The doctor's expression grew blacker and blacker, though she said nothing more about unhooking Ann. But it was in her eye. Sax took to sleeping on the floor in Ann's room. He grew to know the rhythm of her breathing. He spent a lot of time with a hand cradling her head, as Michel had told him Nirgal had done with him. He very much doubted that this had ever cured anybody of anything, but he did it anyway. Sitting for so long in such a posture, he had occasion to think about the brain plasticity treatments that Vlad and Ursula had administered to him after his stroke. Of course a stroke was a very different thing than a coma. But a change of mind was not necessarily a bad thing, if one's mind was in pain.

More days pa.s.sed without a change, each day slower and blanker and more fearful than the one before. The incubators in the Da Vinci labs had long since cooked up a full set of corrected Ann-specific DNA strands, and antisense reinforcers, and glue-ons- the whole gerontological package, in its latest configuration.

So one night he called up Ursula, and had a long consultation with her. She answered his questions calmly, even as she struggled with the idea of what he wanted to do. "The synaptic stimulus package we gave you would produce too much synaptic growth in undamaged brains," she said firmly. "It would alter personality to no set pattern." Creating madmen like Sax, her alarmed look said.
