Green Mars

  But home had Changed. Or he had. Between the attempt to save Simon and the trip with Coyote, he had become a youth apart from the rest; the distinguishing adventures that he had so longed for had come, and their only result was to exile him from his friends. Jackie and Dao hung together more tightly than ever, and acted like a shield between him and all the younger sansei. Quickly Nirgal realized that he hadn’t really wanted to be different after all. He only wanted to melt back into the closeness of his little pack, and be one with his siblings.

  But when he came among them they went silent, and Dao would lead them off, after the most awkward encounters imaginable. And he was left to return to the adults, who began to keep him with them in the afternoons, as a matter of course. Perhaps they meant to spare him some of his pack’s hard treatment, but it only had the effect of marking him even more. There was no cure for it. One day, walking the beach unhappily in the gray and pewter twilight of a fall afternoon, it occurred to him that his childhood was gone. That was what this feeling was; he was something else now, neither adult nor child, a solitary being, a foreigner in his own country. The melancholy realization had a peculiar’ pleasure to it.

  One day after lunch Jackie stayed behind with him and Hiroko, who had come in for the day to teach, and demanded to be included in her afternoon lesson. “Why should you teach him and not me?”

  “No reason,” Hiroko said impassively. “Stay if you want. Get out your lectern and call up Thermal Engineering, page one oh five oh. Well model Zygote Dome for example. Tell me what is the warmest point under the dome?”

  Nirgal and Jackie attacked the problem, competing and yet side by side. He was so happy she was there that he could hardly remember the problem, and Jackie raised a finger before he had even organized his thinking about it. And she laughed at him, a bit scornful but also pleased. Through all these enormous changes in them both there remained in Jackie that capacity for infectious joy, that laughter from which it was so painful to be exiled. . . .

  “Here is a question for next time,” Hiroko said to them. “All the names for Mars in the areophany are names given to it by Terrans. About half of them mean fire star in the languages they come from, but that is still a name from the outside. The question is, what is Mars’s own name for itself?”

  Several weeks later Coyote came through again, which made Nirgal both happy and nervous. Coyote took a morning teaching the children, but fortunately he treated Nirgal the same as all the rest. “Earth is in very bad shape,” he told them as they worked on vacuum pumps from the liquid-sodium tanks in the Rickover, “and it will only get worse. That makes their control over Mars all the more dangerous to us. Well have to hide until we can cut ourselves free of them entirely, and then stand safe to the side while they descend into madness and chaos. You remember my words here, this is a prophecy as true as truth.”

  “That isn’t what John Boone said,” Jackie declared. She spent many of her evening hours exploring John Boone’s Al, and now she pulled out the box from her thigh pocket, and with only the briefest search for a passage, the friendly voice from the box was saying, “Mars will never be truly safe until Earth is too.”

  Coyote laughed raucously. “Yes, well, John Boone was like that, wasn’t he. But you note he is dead, while I’m still here.”

  “Anyone can hide,” Jackie said sharply. “But John Boone got out there and led. That’s why I’m a Boonean.”

  “You’re a Boone and a Boonean!” Coyote exclaimed, teasing her. “And Boonean algebra never did add up. But look here, girl, you have to understand your grandfather better than that if you want to call yourself a Boonean. You can’t make John Boone into any kind of dogma and be true to what he was. I see other so-called Booneans out there doing just that, and it makes me laugh when it doesn’t make me foam at the mouth. Why, if John Boone were to meet you and talk to you for even just an hour, then at the end of that time he would be a jackie-ist. And if he met Dao and talked to him, then he would become a Daoist, maybe even a Maoist. That’s just the way he was. And that was good, you see, because what it did was put the responsibility for thinking back onto us. It forced us to make a contribution, because without that Boone couldn’t operate. His point was not just that everyone can do it, but that everyone should do it.”

  “Including all the people on Earth,” Jackie replied.

  “Not another quick one!” Coyote cried. “Oh you girl, why don’t you leave these boys of yours and marry me now, I got a kiss like this vacuum pump, here, come on,” and he waved the pump at her and Jackie knocked it aside and shoved him back and ran, just for the fun of the chase. She was now the fastest runner in Zygote bar none, even Nirgal with all his endurance could not sprint the way she did, and the kids laughed at Coyote as he skipped after her; he was pretty swift himself for an ancient, and he turned and jinked and went after them all, growling and ending up at the bottom of a pile-on, crying “Oh my leg, oh I’m going to get you for that, you boys are just jealous of me because I’m going to steal your girl away, oh! Stop! Oh!”

  This kind of teasing made Nirgal uncomfortable, and Hiroko didn’t like it either. She told Coyote to stop, but he just laughed at her. “You’re the one that’s gone and made yourself a little incest camp,” he said. “What are you going to do, neuter them?” He laughed at Hiroko’s dark expression. “You’re going to have to farm them out soon, that’s what you’re going to have to do. And I might as well get some of them.”

  Hiroko dismissed him, and soon after that he was off on a trip again. And the next time Hiroko taught, she took all the kids to the bathhouse and they got in the bath after her and sat on the slick tiles in the shallow end, soaking in the hot steamy water while Hiroko spoke. Nirgal sat next to Jackie’s long-limbed naked body which he knew so well/including all its dramatic changes of the past year, and he found that he was unable to look at her.

  His ancient naked mother said, “You know how genetics works, I’ve taught you that myself. And you know that many of you are half brothers and sisters, uncles and nieces and cousins and so forth. I am mother or grandmother to many of you, and so you should not mate and have children together. It’s as simple as that, a very simple genetic law.” She held up a palm, as if to say, This is our shared body.

  “But all living things are filled with viriditas,” she went on, “the green force, patterning outward. And so it is normal that you will love each other, especially now that your bodies are blooming. There is nothing wrong with that, no matter what Coyote says. He is only joking in any case. And in one thing he is right; you will soon be meeting many other people your age, and they will eventually become mates and partners and coparents with you, closer to you even than your tribe kin, whom you know too well to ever love as an other. We here are all pieces of your self; and true love is always for the other.”

  Nirgal kept his eyes on his mother’s, his gaze blank. Still he knew exactly when Jackie had brought her legs together, he had felt the minute change in temperature in the water swirling between them. And it seemed to him that his mother was wrong in some of what she had said. Although he knew Jackie’s body so well, she was still in most ways as distant as any fiery star, bright and imperious in the sky. She was the queen of their little band, and could crush him with a glance if she cared to, and did fairly often even though he had been studying her moods all his life. That was as much otherness as he cared to handle. And he loved her, he knew he did. But she didn’t love him back, not in the same way. Nor did she love Dao in that way, he thought, at least not anymore; which was a small comfort. It was Peter she watched in the way that he watched her. But Peter was away most of the time. So she loved no one in Zygote the way Nirgal loved her. Perhaps for her it was already as Hiroko had said, and Dao and Nirgal and the rest were simply too well known. Her brothers and sisters, no matter the genes involved.

  Then one day the sky fell in earnest. The whole highest part of the water ice sheet cracked away from the CO2, collapsing through the mesh and into the lake
and all over the beach and the surrounding dunes. Luckily it happened in the early morning when no one was down there, but in the village the first booms and cracks were explosively loud, and everyone rushed to their windows and saw most of the fall: the giant white sections of ice dropping like bombs or spinning down like skipped plates, and then the whole surface of the lake exploding and spilling out over the dunes. People came charging out of their rooms, and in the noise and panic Hiroko and Maya herded the kids into the school, which had a discrete air system. When a few minutes had passed and it appeared that the dome itself was going to hold, Peter and Michel and Nadia ran off through the debris, dodging and jumping over the shattered white plates, around the lake to the Rickover to make sure it was all right. If it wasn’t it would be a deadly mission for the three of them, and mortal danger to everyone else. From the school window Nirgal could see the far shore of the lake, which was cluttered with icebergs. The air was aswirl with screaming gulls. The three figures twisted along the narrow high path just under the edge of the dome, and disappeared into the Rickover. Jackie chewed her knuckles in fear. Soon they phoned back a report, all was well. The ice over the reactor was supported by a particularly close-meshed framework, and it had held.

  So they were safe, for the moment. But over the next couple of days, spent in the village in an unhappy state of tension, an investigation into the cause of the fall revealed that the the whole mass of dry ice over them had sagged ever so slightly, cracking the layer of water ice and sending it down through the mesh. Sublimation on the surface of the cap was apparently speeding up to a remarkable degree, as the atmosphere thickened and the world warmed.

  During the next week the icebergs in the lake slowly melted, but the plates scattered over the dunes were still there, melting ever so slowly. The youngsters weren’t allowed on the beach anymore; it wasn’t clear how stable the remainder of the ice layer was.

  The tenth night after the collapse they had a village meeting in the dining hall, all two hundred of them. Nirgal looked around at them, at his little tribe; the sansei looked frightened, the nisei defiant, the issei stunned. The old ones had lived in Zygote for fourteen Martian years, and no doubt it was hard for them to remember any other life; impossible for the children, who had never known anything else.

  It did not need saying that they would not surrender themselves to the surface world. And yet the dome was becoming untenable, and they were too large a group to impose themselves on any of the other hidden sanctuaries. Splitting up would solve that problem, but it wasn’t a happy solution.

  It rook an hour’s talk to lay all this out. “We could try Vishniac,” Michel said. “It’s big, and they’d welcome us.”

  But it was the Bogdanovists’ home, not theirs. This was the message on the faces of the old ones. Suddenly it seemed to Nirgal that they were the most frightened of all.

  He said, “You could move back farther under the ice.”

  Everyone stared at him.

  “Melt a new dome, you mean,” Hiroko said.

  Nirgal shrugged. Having said it, he realized he disliked the idea.

  But Nadia said, “The cap is thicker back there. It will be a long time before it sublimes enough to trouble us. By that time everything will have changed.”

  There was a silence, and then Hiroko said, “It’s a good idea. We can hold on here while a new dome is being melted, and move things over as space becomes available. It should only take a few months.”

  “Shikata ga nai,” Maya said sardonically. There is no other choice. Of course there were other choices. But she looked pleased at the prospect of a big new project, and so did Nadia. And the rest of them looked relieved that they had an option that kept them together, and hidden. The issei, Nirgal saw suddenly, were very frightened of exposure. He sat back, wondering at that, thinking of the open cities he had visited with Coyote.

  They used steam hoses powered by the Rickover to melt another tunnel to the hangar, and then a long tunnel under the cap, until the ice above was three hundred meters deep. Back there they began subliming a new round domed cavern, and digging a shallow lakebed for a new lake. Most of the CO2 gas was captured, refrigerated to the outside temperature, and released; the rest was broken down into oxygen and carbon, and stored for use.

  While the excavation went on they dug up the shallow runner roots of the big snow bamboos, and cantilevered them out of the ground and hauled them on their largest truck down the tunnel to the new cave, scraping leaves all the way. They disassembled the village’s buildings, and relocated them. The robot bulldozer and trucks ran all hours of the day and night, scooping up the battered sand of the old dunes and carting it back down into the new cave; there was too much biomass in it (including Simon) to leave behind. In essence they were taking everything inside the shell of Zygote dome along with them. When they were done, the old cave was nothing but an empty bubble at the bottom of the polar cap, sandy ice above, icy sand below, the air in it nothing but the ambient Martian atmosphere, 170 millibars of mostly CO2 gas, at 240° Kelvin. Thin poison.

  One day Nirgal went back with Peter to take a look at the old place. It was shocking to see the only home he had ever had reduced to such a shell—the ice all cracked above, the sand all torn up, the raw root holes of the village gaping like horrible wounds, the lakebed scraped clear even of its algae. It looked small and ramshackle, some desperate animal’s den. Moles in a hole, Coyote had said. Hiding from vultures. “Let’s get out of here,” Peter said sadly, and they walked together down the long bare poorly lit tunnel to the new dome, stepping along the concrete road Nadia had built, now all ratcheted with treadmarks.

  They laid out the new dome in a new pattern, with the village away from the tunnel lock, near an escape tunnel that ran far under the ice, to an exit in upper Chasma Australe. The greenhouses were set nearer the perimeter lights, and the dune crests were higher than before, and the weather equipment was set right next to the Rickover. There were any number of small improvements of that sort, which kept it from being a replica of their old home. And every day they were so busy with the work of constructing it that there was no time to think much about the change; morning classes in the schoolhouse had been canceled since the fall, and now the kids were merely a rotating work crew, assigned to whoever needed help the most on that particular day. Sometimes the adult overseeing them would try to make their work into a lesson—Hiroko and Nadia were especially good at this—but they had little time to spare, and only added an explanatory sentence to instructions that were too simple to need explanation in any case: tightening wall modules with Allen wrenches, carrying around planters and algae jars in the greenhouses, and so on. It was just work—they were part of the workforce, which was too small for the task even so, despite the versatile robots that looked like rovers stripped of their exteriors. And running around, doing the work, Nirgal was for the most part happy.

  But once as he left the schoolhouse and saw the dining hall, rather than the big shoots of Creche Crescent, the sight brought him up short. His old familiar world was gone, gone forever. That was how time worked. It sent a pang through him that brought tears to his eyes, and he spent the rest of that day somewhat stunned and distant, as if always a step or two behind himself, watching everything that happened drained of emotion, detached as he had been after Simon’s death, exiled to the white world one step outside the green. There was nothing to indicate that he would ever come out of such a melancholy state, and how could he know if he ever would? All those days of his childhood were gone, along with Zygote itself, and they would never come back, and this day too would pass and disappear, this dome too slowly sublime away and crash in on itself. Nothing would last. So what was the point? For hours at a time this question plagued him, taking the taste and color out of everything, and’ when Hiroko noticed how subdued he was, and inquired what was wrong, he simply asked her outright. There was that advantage to Hiroko; you could ask her anything, including the fundamental questions. “Why do we do all
this, Hiroko? When it all goes white no matter what?”

  She stared at him, birdlike, her head cocked to one side. He thought he could see her affection for him in that cock of the head, but he wasn’t sure; as he got older he felt he understood her (along with everyone else) less and less.

  She said, “It is sad the old dome is gone, isn’t it. But we must focus on what is coming. This too is viriditas. To concentrate not on what we have created, but what we will create. The dome was like a flower which wilts and falls, but contains the seed of a new plant, which grows and then there are new flowers and new seeds. The past is gone. Thinking about it will only make you melancholy. Why, I was a girl in Japan once, on Hokkaido Island! Yes, as young as you! And I can’t tell you how far gone that is. But here we are now, you and me, surrounded by these plants and these people, and if you pay attention to them, and how you can make them increase and prosper, then the life comes back into things. You feel the kami inside all things, and that is all you need. This moment itself is all we ever live in.”

  “And the old days?”

  She laughed at that. “You’re growing up. Well, you must remember the old days from-time to time. They were good ones, weren’t they? You had a happy childhood; that is a blessing. But so will these days be good. Take this moment right here, and ask yourself, What now is lacking? Hmmm? . . . Coyote says that he wants you and Peter to go along with him on another trip. Maybe you should go and get out under the sky again, what do you say?”

  So preparations for another trip with Coyote were made, and they continued to work on the new Zygote, informally rechristened Gamete. At night in the relocated dining hall the adults talked for a long time about their situation. Sax and Vlad and Ursula, among others, wanted back into the surface world. They couldn’t do their real work properly in the hidden sanctuaries; they wanted back into the full flood of medical science, terraforming, construction. “We’ll never be able to disguise ourselves,” Hiroko said. “No one can change their genomes.”
