He grinned, left it at that. In his room he lay on his bed, Mangalavid on the TV, thinking things over. Brushing his teeth before going to sleep, he looked his mirror image in the eye and scowled. He waved his toothbrush in the expansive gesture: “Vell,” he said in an unfair parody of Helmut’s slight accent, “ziss is business, you know! Business as usual!”

The next morning he had a few hours before his first meeting, and so he spent the time with Pauline, going over what he could find out about Helmut Bronski’s doings in the last six months. Could Pauline get into the UNOMA diplomatic pouch? Had Helmut ever been to Senzeni Na, or any of the other sabotage sites? While Pauline ran through her search algorithms John swallowed an omegendorph to kill his hangover, and thought about what lay behind this inspiration to search Helmut’s records. UNOMA constituted the ultimate authority on Mars these days, at least according to the letter of the law. In practice, as last night had made clear, it had the UN’s usual toothlessness before national armies and transnational money; unless it did their bidding it was helpless, it could not succeed against their desires and probably would never even try, as it was their tool. So what did they want, the national governments and the transnational boards of directors? If enough sabotages occurred, would that constitute a reason to bring in more of their own security? Would it tend to increase their control?

He made a disgusted noise. Apparently the only result of his investigation so far was that the list of suspects had tripled. Pauline said, “Excuse me, John,” and the information came up on her screen. The diplomatic pouch, she had found, was coded in one of the new unbreakable encryptions: you’d have to get the decryptions to enter it. Helmut’s movements, on the other hand, were easily traceable. He had been to Pythagoras, the mirror station that had been spun out of orbit, ten weeks ago. And to Senzeni Na two weeks before John’s visit. And yet no one at Senzeni Na had mentioned his appearance.

Most recently, he had just returned from the mining complex being set up at a place called Bradbury Point. Two days later John left to visit it.

Bradbury Point was located some eight hundred kilometers north of Burroughs, at the easternmost extension of the Nilosyrtis Mensae. The mensae were a series of long mesas, like islands of the southern highlands standing out in the shallows of the northern plains. The island mesas of Nilosyrtis had recently been found to be a rich metallogenic province, with deposits of copper, silver, zinc, gold, platinum and other metals. Concentrations of ore like this had been discovered in several locations on the so-called Great Escarpment, where the southern highlands dropped to the northern lowlands. Some areologists were going so far as to label the entire escarpment region a metallogenic province, banding the planet like the stitching on a baseball. It was another odd fact to add to the great north-south mystery, and a fact that was, of course, getting more than its share of attention. Excavations accompanied by intensive areological studies were being conducted by scientists working for UNOMA and, John discovered as he checked new arrivals’ employment records, the transnationals; all trying to find clues that would enable them to locate more deposits. But even on Earth the geology of mineral formation was not well understood, which was why prospecting still had large elements of chance in it; and on Mars, it was more mysterious yet. The recent finds on the Great Escarpment had been mostly an accident, and only now was the region becoming the main focus for prospecting.

The discovery of the Bradbury Point complex had accelerated this hunt, as it was turning out to be as big as the largest Terran complexes, perhaps the equal of the Bushveldt Complex of Azania. So: a gold rush in Nilosyrtis. And Helmut Bronski had visited the scene.

Which turned out to be small and utilitarian, a mere beginning; a Rickover and some refineries, next to a mesa hollowed out and filled by a habitat. The mines were scattered in the lowlands between mesas. Boone drove up to the habitat, coupled to the garage, then ducked through the locks. Inside a welcoming committee greeted him, and took him up to a window-walled conference room to talk.

There were, they said, about three hundred people in Bradbury, all employees of UNOMA, and trained by the transnational Shellalco. When they took John on a brief tour, he found they were a mix of ex-South Africans, Australians and Americans, all happy to shake his hand; about three-quarters men, pale and clean, looking more like lab techs than the blackened trolls John envisioned when he heard the word miner. Most of them were working on two-year contracts, they told him, and keeping track of the time they had left, by the week or even by the day. They ran the mines mostly by teleoperation, and looked shocked when Boone asked to go down into a mine for a look around. “It’s just a hole,” one said. Boone stared at them innocently; and after another moment’s hesitation, they scrambled to gather an escort team to take him out.

It took them two hours to get into walkers and out of a lock. They drove to the rim of a mine, and then down a ramp road into a terraced oval pit some two kilometers long. There they got out, and followed John as he walked around. Surrounded by big robotic dozers and dumptrucks and earth movers, his four escorts’ faceplates were all eyes; on the alert for a behemoth on the loose, John guessed. He stared at them, amazed at their timidity; it made him realize, all of a sudden, that Mars could be just another version of the hardship assignment, a hellish combination of Siberia, the interior of Saudi Arabia, the South Pole in winter, and Novy Mir.

Or else they just thought he was a dangerous man to be around. Which gave him a start. Everyone had no doubt heard of the falling dump truck; maybe it was just that. But could it be something more? Might these people be aware of something that he wasn’t? Reflecting on this for a while, John found his own eyes beginning to press glass; he had been thinking of the falling truck as an accident, or at least something that could only happen once. But his movements were easy to trace, everyone knew where he was. And every time you went outdoors you were only a walker away, as they said. And in a pit mine there were a lot of behemoths about …

But they got back in without incident. And that night they had the usual dinner and party in his honor, a hard-drinking party, with a lot of omegendorph consumption and loud raucous talk: a bunch of young tough engineers, pleased to find that John Boone was actually a fun guy to party with. A fairly common reaction among newcomers, especially younger men. John chatted them up, and had a good time, and slipped his inquiries into the flow pretty unnoticeably, he thought. They had not heard of the Coyote, which was interesting, as they did know about Big Man, and the hidden colony. Apparently the Coyote was not in that category of tale; he was some kind of insider thing, known, so far as John could tell, only to some of the first hundred.

The miners had had a recent unusual visit, however; an Arab caravan had come by, traveling the edge of Vastitas Borealis. And, they said, the Arabs had claimed to have been visited by some of “the lost colonists”, as they called them.

“Interesting,” John said. It seemed unlikely to him that Hiroko or any of her crew would reveal themselves, but who could tell. He might as well go check it out; after all, there was only so much he could do at Bradbury Point. Very little detective work, he was noticing, could be accomplished before a crime occurred. So he spent a couple more days observing the mining, but that told him little; it only reinforced his shock at the scale of the operation, at how much robotic earthmovers could tear away. “What are you going to do with all the metal?” he asked, after taking a look down into another great open pit mine, located twenty-five kilometers to the west of the habitat. “Getting it to Earth will cost more than it’s worth, won’t it?”

The chief of operations, a black-haired man with a hatchet face, grinned. “We’ll hold onto it until it’s worth more. Or until they build that space elevator.”

“You believe in that?”

“Oh yeah, the materials are there! Graphite whisker reinforced with diamond spirals, why you could almost build one on Earth with that. Here, it would be easy.”

John shook his head. That afternoon they drove for an hour back to the habitat, past raw pits and slag heaps, toward the distant plume of the refineries on the other sides of the habitat mesa. He was used to seeing the land torn up for building purposes, but this … it was amazing what a few hundred people could do. Of course it was the same technology that was allowing Sax to build a vertical town the whole height of the Echus Overlook, the same technology that allowed all the new towns to be built so quickly; but still, wreaking such havoc just to strip away metals, destined for Earth’s insatiable demand …

The next day he gave the operations chief a fiendishly tight security regimen, to be followed for two months; and then drove out into the wind-eroded tracks of the Arab caravan, and followed them north and east.

It turned out that Frank Chalmers was traveling with this Arab caravan. But he had not seen or heard of any visitation by Hiroko’s people, and none of the Arabs would admit to being the one who had told the story at Bradbury Point. A false lead, then. Or else one that Frank was helping the Arabs to eliminate; and if so, how would John find that out? Though the Arabs had only recently arrived on Mars, they were already Frank’s allies, no doubt about it; he lived with them, he spoke their language, and now, naturally, he was the constant mediator between them and John. Not a chance of an independent investigation, except what Pauline could do in the records, which she could do as well away from the caravan as in it.

Nevertheless, John traveled with them for a while as they roamed the great dune sea, doing areology and a bit of prospecting. Frank was only there briefly himself, to talk to an Egyptian friend; he was too busy to stay anywhere for long. His job as US Secretary made him as much of a globe-trotter as John, and they crossed paths pretty frequently. Frank had managed to keep his position as the American department head now through three administrations, even though it was a cabinet post; a remarkable feat, even without considering his distance from Washington. And so he was now overseeing the introduction of investment by the American-based transnationals, a responsibility that made him manic with overwork and puffed up with power, what John thought of as the business version of Sax, always moving, always gesturing with his hands as if conducting the music of his speech, which had shifted over the years to full-tilt Chamber of Commerce overdrive, “Got to stake a claim on the Escarpment before the transnats and the Germans snap everything up, lotta work to be done!” which was his constant refrain, often said while pointing for illustration at the little globe he carried with him in his lectern pocket. “Look at your moholes, I just entered them last week, one near the north pole, three in the sixties north and south, four along the equator, one near the south pole, all of them nicely placed west of volcanic rises to catch their updrafts, it’s beautiful.” He spun the globe and the blue dots marking the moholes blurred for a moment into blue lines. “It’s good to see you finally doing something useful.”

“Finally.”

“Look, here’s the new habitat factory in Hellas. They’re manufacturing starter units at a rate that’ll enable them to handle some three thousand emigrants per Ls ninety, and given the new fleet of roundtrip shuttles, that’s just barely enough.” He saw John’s expression and said quickly, “All heat in the end, John, so it helps the terraforming with more than just money and labor, I mean think about it.”

“But do you ever wonder what’s going to come of it all?” John asked.

“What do you mean?”

“You know, this deluge of people and equipment, while things are falling apart on Earth.”

“Things are always going to be falling apart on Earth. You might as well get used to it.”

“Yeah, but who’s going to own what up here? Who’s going to call the shots?”

Frank just made a face at John’s naïveté, at the very nature of the question. One look at his grimace and John could read it all, the whole complex of disgust and impatience and amusement. A part of John was pleased at this instant recognition; he knew his old friend better than he had ever known any of his family, so that the swarthy pale-eyed face glowering at him was like that of a brother, a twin that he couldn’t ever remember not knowing. On the other hand, he was annoyed with Frank for his condescension. “People are wondering about it, Frank. It’s not just me, and it’s not just Arkady. You can’t just shrug it off and act like it’s a stupid question, like there’s nothing to be decided.”

“The UN decides,” Frank said brusquely. “There’s ten billion of them, and ten thousand of us. That’s a million to one. If you want to influence those kind of odds you ought to have become the UNOMA factor like I told you to when they set up the position. But you didn’t listen to me. You just shrugged it off. You could have really done something, but now what are you? Sax’s assistant in charge of publicity.”

“And development, and security, and Terran affairs, and the moholes.”

“Ostrich!” Frank pounced. “Head in a hole! Come on, let’s go eat.”

John agreed and they went off to a dinner in the Arabs’ biggest rover, a meal of basted lamb and dill-flavored yogurt, delicious and exotic. But John found himself still irritated at Frank’s scorn, which never let up. The old rivalry, sharp as ever; and no First Man routine would ever make a dent in Frank’s sneery arrogance.

Thus when Maya Toitovna showed up unexpectedly the next day, traveling west on her way to Acheron, John gave her a longer hug than he might have otherwise; and by the time that night’s dinner was over, he had made certain that she would spend the night in his rover – a matter of a particular attentiveness, a certain laugh, a certain look, the nearly-accidental brushing of arms together as they stood trying sherbets, talking to the happy men of the caravan, who clearly found her fascinating … all their old code of conciliation and seduction, established through the years. And Frank could only watch, deadpan, talking in Arabic to his Egyptian friends.

And that night, as John and Maya made love in John’s rover bed, John pulled up from her briefly and looked down at her white body, and thought, So much for political power Frank buddy! That deadpan look had told it all, the fierce desire for Maya still there, still burning. Frank, like most of the men in the caravanserai that night, would have loved to have been in John’s place at that moment; once or twice in the past he no doubt had been; but not when John was around. No, tonight Frank would be reminded what real power was made of.

Distracted by such nastiness, it took John a while to pay any real attention to Maya herself. It had been almost five years since he and she had slept together, and in the intervening time he had had several other partners, and knew she had lived for a time with an engineer in Hellas. It was strange to begin again, as they knew each other intimately and yet didn’t. Her turning face flickering under him in the dim light, sister then stranger, sister then stranger … Something happened, then, something turned in him; all that exterior business fell away, all those games. Something in her face, in the way she was all there, the way she would give her whole self to him when they made love. He didn’t know anyone else who was quite like that.

And thus the old flame sparked again, uncertainly at first, as it had not been there at all in their first lovemaking. But then, after an hour’s quiet talk, they had started kissing and rolled together and suddenly it was ablaze and they were inside it. Lit up by Maya as usual, he had to admit it. She made him pay attention. Sex for her was not (as it tended to be for John) some kind of extension of sport; it was a grand passion, a transcendent state of being, and she was so tigerish when she got going that she always surprised him, woke him up, brought him up to her level, reminded him what sex could be. And it was wonderful to be reminded again, to learn that again; really wonderful. Omegendorph was nothing to it, how could he have forgotten, why did he keep wandering away from her as if she weren’t, somehow, irreplaceable? He crushed her with a hug and they twisted together, bit at each other, panted and moaned; came together as they had so often before, Maya pulling him over the edge with her. Their ritual.

And even afterwards, just talking, he somehow felt very much more fond of her. He had started things just to irk Frank, it was true; he had been completely careless of her; but now, lying beside her, he could feel how much he had missed her presence in the previous five years, how bland life had seemed. How much he had missed her! New feelings – they always surprised him, he kept assuming he was too old for them, that he had more or less stopped changing. And then something would happen. And so often that something (thinking back over the years) was a meeting with Maya …

She was still the same Maya Toitovna, however: mercurial, full of her own thoughts and plans, full of herself; she had no idea what John was doing out there on the dunes, and would never think to ask. And she would slash him to ribbons if he accidentally crossed her mood, he could tell that just in the sultry set of her shoulders, just in the way she padded off to the toilet. But he knew all that already, it was old news, something from the first years at Underhill, so long ago; and the sheer familiarity of it was pleasing – even her irritability was pleasing! Like Frank and his scorn. Well, he was getting old, and they were family. He almost laughed, he almost said something to set her off, then thought better of it. Just knowing was enough, no need for another demonstration, Lord! At that thought he did laugh, and she smiled to hear it, and came back to bed and shoved him in the chest. “Laughing at me again I see! Because of my fat bottom is it?”

“You know your bottom is perfect.” She shoved him again, insulted at what she considered a gross lie, and their wrestling drew them back into the reality of skin and salt, into the world of sex. At some point in the long lazy session he found himself thinking I love you, wild Maya, I really do. It was a disconcerting thought, a dangerous thought. Not something he would risk saying. But it felt true.

So a couple of days later, when she left to visit the Acheron group, and asked him to join her there, he was pleased. “Maybe in a couple of months.”

“No, no.” Her face was serious. “Come sooner, I want you there with me sooner.”

And when he agreed, on a whim, she grinned like a girl with a secret. “You won’t be sorry.” With a kiss she was off, driving south to Burroughs to catch the train west.

After that, there was less chance than ever of learning anything from the Arabs. He had offended Frank, and the Arabs closed ranks behind their friend, as was only right. Hidden colony? they said. What was that?

He sighed, gave up on it and decided to leave. Stocking his rover the night before his departure (the Arabs were punctilious about filling his hold with supplies), he pondered what he had accomplished so far in his investigation of the sabotages. So far Sherlock Holmes was in no danger, that was sure. Worse than that, there was now a whole society on Mars that was basically impenetrable to him. Moslems, what were they exactly? He read Pauline that evening after he was done stocking, and then he rejoined his hosts and watched them as closely as he was able, asking questions all that night long … He knew asking questions was the key to people’s souls, infinitely more useful than wit; but in this case it didn’t seem to make any difference. Coyote? Some kind of wild dog was it?

Baffled, he left the caravan the next morning and drove west, on the southern border of the dune sea. It would be a long journey to Acheron to join Maya, five thousand kilometers of dune after dune; but he preferred driving to going down to Burroughs and taking the train. He needed time to think. And really it was a kind of habit now, driving cross-country, or flying gliders – getting away, traveling slowly across the land. He had been on the road for years now, criss-crossing the northern hemisphere and making long excursions into the south, inspecting moholes or doing favors for Sax or Helmut or Frank, or looking into things for Arkady, or cutting ribbons at the opening of one thing or another – a town, a well, a weather station, a mine, a mohole – and always talking, talking in public speeches or private conversations, talking to strangers, old friends, new acquaintances, talking almost as fast as Frank did, and all in an attempt to inspire the people on the planet to figure out a way to forget history, to build a functioning society. To create a scientific system designed for Mars, designed to their specifications, fair and just and rational and all those good things. To point the way to a new Mars!

And yet after every year that passed, it seemed less likely to happen the way he had envisioned it. A place like Bradbury Point showed how rapidly things were changing, and people like the Arabs confirmed the impression; events were out of his control, and more than that, out of anyone’s control. There was no plan. He rolled west on autopilot, up and down over dune after dune, not seeing a thing, sunk deep in an attempt to understand what exactly history was, and how it worked. And it seemed to him as he drove on day after day that history was like some vast thing that was always over the tight horizon, invisible except in its effects. It was what happened when you weren’t looking – an unknowable infinity of events, which although out of control, controlled everything. After all, he had been here from the very beginning! He had been the beginning, the first person to step on this world, and then he had returned against all the odds, and helped to build it from scratch! And yet now, despite all that, it was spinning away from him. Contemplating that fact made him tense with disbelief, and sometimes with a sudden furious frustration; to think that the whole thing was accelerating not only beyond his control, but even beyond his ability to comprehend – it wasn’t right, he had to fight it!

And yet how? Social planning of some sort … clearly they had to have it. This flailing about without a plan, in violation of even the flimsy plan people had made back at the beginning with the Mars treaty … well, societies without a plan, that was history so far; but history so far had been a nightmare, a huge compendium of examples to be avoided. No. They needed a plan. They had a chance at a new start here, they needed a vision. Helmut the oily functionary, Frank with his cynical acceptance of the status quo, his acceptance of the breakdown of the treaty, as if they were in a kind of gold rush; Frank was wrong. Wrong as usual!

But his own rushing about was probably wrong too. He had been operating on the unarticulated theory that if he only saw more of the planet, visited one more settlement, talked to one more person, that he would somehow (without really thinking too hard) get it – and that his holistic understanding would then flow back from him to everybody else, spreading out through all the new settlers and changing things. Now he was pretty sure that this feeling had been naive; there were so many people on the planet these days, he could never hope to connect with them, to become the articulator of all their hopes and desires. And not only that, but few of the newcomers seemed much like the first hundred in regard to their reasons for coming. Well, that wasn’t entirely true; there were still scientists coming up, and people like the Swiss roadbuilding gypsies. But he didn’t know them like he did the first hundred, and he never would. That little band had formed him, really, they had shaped his opinions and ideas, had taught him; they were his family, he trusted them. And he wanted their help, he needed it now more than ever. Perhaps it was that which explained the sudden new intensity of his feeling for Maya. And perhaps it was this that made him so angry with Hiroko – he wanted to talk to her, he needed her help! And she had abandoned them.

Vlad and Ursula had relocated their biotech complex to a finlike ridge in the Acheron Fossae, a narrow prominence which looked like the conning tower of a vast submerged submarine. They had honeycombed the upper part of it with excavations that extended from cliff to cliff; some of the rooms were a kilometer wide, and glass-walled on both sides. The windows on the south side had a view of Olympus Mons, some six hundred kilometers away; north-facing windows looked down onto the pale tan sands of Arcadia Planitia.

John drove up a wide ledge to the bottom of the fin, and plugged into the garage lock door, noticing as he did that the ground in the narrow canyon south of the settlement was lumpy with heaps of what appeared to be melted brown sugar.

“It’s a new kind of cryptogamic crust,” Vlad said when John asked him about it. “A symbiosis of cyanobacteria and Florida platform bacteria. The platform bacteria go very deep, and convert sulfates in the rock to sulfides, which then feed a variant of Microcoleus. The top layers of that grow in filaments, which bind to sand and clay in big dendritic formations, so it’s like little forest sylvanols with really long bacterial root systems. It looks like these root systems will keep on going right down through the regolith to bedrock, melting the permafrost as they go.”

“And you’ve released this stuff?” John said.

“Sure. We need something to bust up the permafrost, right?”

“Is there anything to stop it from growing planetwide?”

“Well, it has the usual array of suicide genes in case it begins to overwhelm the rest of the biomass, but if it keeps to its niche …”

“Wow.”

“It’s not too unlike the first life forms that covered the Terran continents, we think. We’ve just enhanced its speed of growth, and its root systems. The funny thing is that I think at first it’s going to cool the atmosphere, even though it’s warming things underground. Because it’ll really increase chemical weathering of the rock, and all those reactions absorb CO

from the air, so the air pressure is going to drop.”

Maya had come up and joined them with a big hug for John, and now she said, “But won’t the reactions release oxygen as fast as they absorb CO

, and keep air pressure up?”

Vlad shrugged. “Maybe. We’ll see.”

John laughed. “Sax is a long term thinker. He’ll probably be pleased.”

“Oh yes. He authorized the release. And he’s coming to study here again when spring comes.”

They had dinner in a hall located high on the fin, just under the crest. Skylights opened above to the greenhouse on the crest itself, and windows ran the length of the north and south walls; stands of bamboo filled the walls to east and west. All the residents of Acheron were there for dinner, holding to an Underhill custom as they did in many other ways. The discussion at John and Maya’s table ranged widely, but kept returning to the current work, which involved trying to solve problems caused by the need to implant safeguards in all the GEMs they were releasing. Double suicide genes in every GEM was a practice the Acheron group had initiated on its own, and it was now going to be codified as UN law. “That’s all well and good for legal GEMs,” Vlad said. “But if some fools try something on their own and blow it, we could be in big trouble anyway.”

After dinner, Ursula said to John and Maya, “Since you’re here you ought to get your physicals. It’s been a while for both of you.”

John, who hated physicals and indeed all medical attention of any kind, demurred. But Ursula hounded him, and eventually he gave in, and visited her clinic a couple days later. There he was put through a battery of diagnostic tests that seemed even more intensive than usual, most of them run by imaging machines and computers with too-relaxing voices, telling him to move this way and then that, while John in complete ignorance did what he was told. Modern medicine. But after all that, he was poked and prodded and tapped in time-honored fashion by Ursula herself. And when it was over he was lying on his back with a white sheet over him, while she stood at his side, looking at read-outs and humming absently.

“You’re looking good,” she told him after several minutes of that. “Some of the usual gravity-related problems, but nothing we can’t deal with.”

“Great,” John said, feeling relieved. That was the thing about physicals; any news was bad news, one wanted an absence of news. Getting that was somehow a victory, and more so every time; but still, a negative accomplishment. Nothing had happened to him, great!

“So do you want the treatment?” Ursula asked, her back to him, her voice casual.

“The treatment?”

“It’s a kind of geronotological therapy. An experimental procedure. Somewhat like an inoculation, but with a DNA strengthener. Repairs broken strands, and restores cell division accuracy to a significant degree.”

John sighed. “And what does that mean?”

“Well, you know. Ordinary ageing is mostly caused by cell division error. After a number of generations, ranging from hundreds to tens of thousands depending which kind of cells you’re talking about, errors in reproduction start to increase, and everything gets weaker. The immune system is one of the first to weaken, and then other tissues, and then finally something goes wrong, or the immune system gets overwhelmed by a disease, and that’s it.”

“And you’re saying you can stop these errors?”

“Slow them down, anyway, and fix the ones that are already broken. A mix, really. The division errors are caused by breaks in DNA strands, so we wanted to strengthen DNA strands. To do it we would read your genome, and then build an auto repair genomic library of small segments that will replace the broken strands—”

“Auto repair?”

She sighed. “All Americans think that is funny. Anyhow we push this auto repair library into the cells, where they bind to the original DNA and help keep them from breaking.” She began to draw double and quadruple helixes as she talked, shifting inexorably into biotech jargon, until John could only catch the general drift of the argument, which apparently had its origins in the genome project and the field of genetic abnormality correction, with application methods taken from cancer therapy and GEM technique. Aspects of these and many other different technologies had been combined by the Acheron group, Ursula explained. And the result seemed to be that they could give him an infection of bits of his own genome, an infection which would invade every cell in his body except for parts of his teeth and skin and bones and hair; and afterwards he would have nearly flawless DNA strands, repaired and reinforced strands that would make subsequent cell division more accurate.

“How accurate?” he asked, trying to grasp what it all meant.

“Well, about like if you were ten years old.”

“You’re kidding.”

“No, no. We’ve all done it to ourselves, back around Ls ten of this year, and so far as we can tell, it’s working.”

“Does it last forever?”

“Nothing lasts forever, John.”

“How long then?”

“We don’t know. We ourselves are the experiment, we figure we’ll find out as we go along. It seems possible we might be able to do the therapy again when the rate of division error begins to increase again. If that is successful, it could mean you would last for quite a while.”

“Like how long?” he insisted.

“Well, we don’t know, do we? Longer than we live now, that’s pretty sure. Possibly a lot longer.”

John stared at her. She smiled at the expression on his face, and he could feel that his jaw was slack with amazement; no doubt he looked less than brilliant, but what did she expect? It was … it was …

He was following his thoughts with difficulty as they skittered around. “Who have you told about this?” he asked.

“Well, we have asked everyone in the first hundred, when they get a check-up with us. And everyone here at Acheron has tried it. And the thing is, we’ve only combined methods that everyone has, so it won’t be long before others try putting it all together too. So we’re writing it up for publication, but we’re going to send the articles first to be reviewed by the World Health Organization. Political fallout, you know.”

“Um,” John said, considering it. News of a longevity drug loose on Mars, back among the teeming billions … my Lord, he thought. “Is it expensive?”

“Not extremely. Reading your genome is the most expensive part, and it takes time. But it’s just a procedure, you know, it’s just computer time. It’s very possible you could inoculate everyone on Earth. But the population problem down there is already critical as it is. They’d have to institute some pretty intense population control, or else they’d go Malthusian really fast. We thought we’d better leave the decisions to the authorities down there.”

“But word is sure to get out.”

“Is that true? They might try to put a clamp on it. Maybe even a comprehensive clamp, I don’t know.”

“Wow. But you folks … you just went ahead and did it?”

“We did.” She shrugged. “So what do you say? Want to do it?”

“Let me think about it.”

He went for a walk on the crest of the fin, up and down the long greenhouse stuffed with bamboo and food crops. Walking west he had to shield his eyes from the glare of the afternoon sun, even through the filtered glass; walking back east, he could look out at the broken slopes of lava stretching up to Olympus Mons. It was hard to think. He was sixty-six years old; born in 1982, and what was it back on Earth now, 2048? M-11, eleven long hi-rad Martian years. And he had spent thirty-five months in space, including three trips between Earth and Mars, which was still the record. He had taken on 195 rems in those trips alone, and he had low blood pressure and a bad HDL to LDL ratio, and his shoulders ached when he swam and he felt tired a lot. He was getting old. He didn’t have all that many years left, weird though it was to think of it; and he had a lot of faith in the Acheron group, who, now that he thought of it, were wandering around their aerie working and eating and playing soccer and swimming and so on with little smiles of absorbed concentration, with a kind of humming. Not like ten year-olds, certainly not; but with an aura of suffused, absorbed happiness. Of health, and more than health. He laughed out loud, and went back down into Acheron looking for Ursula. When she saw him she laughed too. “It’s not really that hard a choice, is it.”

“No.” He laughed with her: “I mean, what have I got to lose?”

So he agreed to it. They had his genome in their records, but it would take a few days to synthesize the collection of repair strands and clip them onto plasmids, and clone millions more. Ursula told him to come back in three days.
