Nadia and Samantha walked over to one of the little rovers they had uncrated and climbed in. Nadia drove the rover across the plain to a tractor they had found the day before about a kilometer to the west. The morning cold cut through her walker in a diamond pattern, as the result of the X weave of the heating filaments in the suit material. A strange sensation, but she had been colder in Siberia many a time and she had no complaints.

They came to the big lander and got out. Nadia picked up a drill with a Phillips screwdriver bit, and started dismantling the crate on top of the vehicle. The tractor inside the lander’s crate was a Mercedes-Benz. She poked the drill into the head of a screw, pulled the trigger and watched the screw spin out. She moved to the next, grinning. Innumerable times in her youth she had gone out in cold like this, with numb white chopped-up hands, and fought titanic battles to unscrew frozen or stripped screws … but here it was ziiip, another one out. And really with the walker it was warmer than it had been in Siberia, and freer than in space, the walker no more restrictive than a thin stiff wetsuit. Red rocks were scattered all around in their uncanny regularity; voices chattered on the common band: “Hey, I found those solar panels!” “You think that’s something, I just found the goddamn nuclear reactor.” Yes, it was a great morning on Mars.

The stacked crate walls made a ramp to drive the tractor off the lander; they didn’t look strong enough, but that was the gravity again. Nadia had turned on the tractor’s heating system as soon as she could reach it, and now she climbed into the cab and tapped a command into its autopilot, feeling that it would be best to let the thing descend the ramp on its own, with her and Samantha watching from the side, just in case the ramp was more brittle in the cold than expected, or otherwise unreliable. She still found it almost impossible to think in terms of Martian g, to trust the designs that took it into account. The ramp just looked too flimsy!

But the tractor rolled down without incident, and stopped on the ground: eight meters long, royal blue, with wire mesh wheels taller than they were. They had to climb a short ladder into the cab. The crane prosthesis was already attached to the mount on the front end, and that made it easy to load the tractor with the winch, the sandbagger, the boxes of spare parts, and finally the crate walls. When they were done, the tractor looked as overloaded and topheavy as a steam calliope; but the g made it only a matter of balance. The tractor itself was a real pig, with six hundred horsepower, a wide wheelbase, and wheels big as tracks. The hydrazine motor had pick-up even worse than diesel, but it was like the ultimate first gear, completely inexorable. They took off and rolled slowly toward the trailer park – and there she was, Nadezhda Cherneshevsky, driving a Mercedes-Benz across Mars! She followed Samantha to the sorting lot, feeling like a queen.

And that was the morning. Back into the habitat, helmet and tank off, a quick bite in walker and boots. With all that running around they were famished.

After lunch they went back out in the Mercedes-Benz, and used it to haul a Boeing air miner to an area east of the habitats, where they were going to gather all the factories. The air miners were big metal cylinders, somewhat resembling 737 fuselages except that they had eight massive sets of landing gear, and rocket engines attached vertically to their sides, and two jet engines mounted above the fuselage fore and aft. Five of these miners had been dropped in the area some two years before. In the time since, their jet engines had been sucking in the thin air and ramming it through a sequence of separating mechanisms, to divide it into its component gases. The gases had been compressed and stored in big tanks, and were now available for use. So the Boeings each now held 5,000 liters of water ice, 3,000 liters of liquid oxygen, 3,000 liters of liquid nitrogen, 500 liters of argon, and 400 liters of carbon dioxide.

It was no easy task hauling these giants across the rubble to the big holding tanks near their habitats, but they needed to do it, because after they were drained into the holding tanks they could be turned on again. Just that afternoon another group had gotten one emptied out and turned back on, and the low hum of its jets could be heard everywhere, even in a helmet or a habitat.

Nadia and Samantha’s miner was more stubborn; in the whole afternoon they only managed to haul it a hundred meters, and they had to use the bulldozer attachment to scrape a rough road for it all the way. Just before sunset they returned through the lock into the habitat, their hands cold and aching with fatigue. They stripped down to their dust-caked underwear and went straight to the kitchen, ravenous once more; Vlad estimated they were each burning about six thousand calories a day. They cooked and gulped down rehydrated pasta, nearly scalding their partially-thawed fingers on their trays. Only when they had finished eating did they go to the women’s changing room and start trying to clean themselves up, sponging down with hot water, changing into clean jumpers. “It’s going to be hard to keep our clothes clean, that dust even gets through the wristlocks, and the waist zippers are like open holes.” “Well yeah, those fines are micron-sized! We’re going to have worse trouble from it than dirty clothes, I can tell you that. It’s going to be getting into everything, our lungs, our blood, our brains …”

“That’s life on Mars.” This was already a popular refrain, used whenever they encountered a problem, especially an intractable one.

On some days after dinner there were a couple hours of sunlight left, and Nadia, restless, would sometimes go back outside. Often she spent the time wandering around the crates that had been hauled to base that day, and over time she assembled a personal tool kit, feeling like a kid in a candy store. Years in the Siberian power industry had given her a reverence for good tools, she had suffered brutally from the lack of them. Everything in north Yakut had been built on permafrost, and the platforms sank unevenly in the summer, and were buried in ice in the winter, and parts for construction had come from all over the world, heavy machinery from Switzerland and Sweden, drills from America, reactors from the Ukraine, plus a lot of old scavenged Soviet stuff, some of it good, some indescribably shoddy, but all of it unmatched – some of it even built in inches – so that they had had to improvise constantly, building oil wells out of ice and string, knocking together nuclear reactors that made Chernobyl look like a Swiss watch. And every desperate day’s work accomplished with a collection of tools that would have made a tinker weep.

Now she could wander in the dim ruby light of sunset, her old jazz collection piped from the habitat stereo into her helmet headphones, as she rooted in supply boxes and picked out any tool she wanted. She would carry them back to a small room she had commandeered in one of the storage warehouses, whistling along with King Oliver’s Creole Jazz Band, adding to a collection that included, among other items, an Allen wrench set, some pliers, a power drill, several clamps, some hacksaws, an impact wrench set, a brace of cold-tolerant bungie cords, assorted files and rasps and planes, a crescent wrench set, a crimper, five hammers, some hemostats, three hydraulic jacks, a bellows, several sets of screwdrivers, drills and bits, a portable compressed gas cylinder, a box of plastic explosives and shape charges, a tape measure, a giant Swiss Army knife, tin snips, tongs, tweezers, three vises, a wirestripper, X-acto knives, a pick, a bunch of mallets, a nut driver set, hose clamps, a set of end mills, a set of jeweler’s screwdrivers, a magnifying glass, all kinds of tape, a plumber’s bob and ream, a sewing kit, scissors, sieves, a lathe, levels of all sizes, long nosed pliers, vise grip pliers, a tap and die set, three shovels, a compressor, a generator, a welding and cutting set, a wheelbarrow—

and so on. And this was just the mechanical equipment, her carpenter’s tools. In other parts of the warehouse they were stockpiling research and lab equipment, geological tools, and any number of computers and radios and telescopes and videocameras; and the biosphere team had warehouses of equipment to set up the farm, the waste recyclers, the gas exchange mechanism, in essence their whole infrastructure; and the medical team had more warehouses of supplies for the clinic, and their research labs, and the genetic engineering facility. “You know what this is,” Nadia said to Sax Russell one evening looking around her warehouse. “It is an entire town, disassembled and lying in pieces.”

“And a very prosperous town at that.”

“Yes, a university town. With first-rate departments in several sciences.”

“But still in pieces.”

“Yes. But I kind of like it that way.”

Sunset was mandatory return-to-habitat time, and in the dusk she would stumble into the lock and inside, and eat another small cold meal sitting on her bed, listening to the talk around her which mostly concerned the day’s work, and the arrangement of the tasks for the next morning. Frank and Maya were supposed to be doing this, but in fact it was happening spontaneously, in a kind of ad hoc barter system. Hiroko was particularly good at it, which was a surprise given how withdrawn she had been on the voyage out; but now that she needed help from outside her team, she spent most of every evening moving from person to person, so single-minded and persuasive that she usually had a sizeable crew working on the farm every morning. Nadia couldn’t really see this; they had five years of dehydrated and canned food on hand, fare that suited Nadia fine, she had eaten worse for most of her life and she paid little attention to food anymore, she might as well have been eating hay, or refueling like one of the tractors. But they did need the farm for growing bamboo, which Nadia planned to use as a construction material in the permanent habitat that she hoped to start building soon. It all interlocked; all their tasks linked together, were necessary to each other. So when Hiroko plopped down beside her, she said, “Yeah, yeah, be there at eight. But you can’t build the permanent farm until the base habitat itself is built. So really you ought to be helping me tomorrow, right?”

“No, no,” Hiroko said, laughing. “Day after, okay?”

Hiroko’s main competition for labor came from Sax Russell and his crowd, who were working to start all the factories. Vlad and Ursula and the biomed group were also hungry to get all their labs set up and running. These three teams seemed willing to live in the trailer park indefinitely, as long as their own projects were progressing; but luckily there were a lot of people who were not so obsessed by their work, people like Maya and John and the rest of the cosmonauts, who were interested in moving into larger and better-protected quarters as soon as possible. So Nadia’s project would get help from them.

When she was done eating, Nadia took her tray into the kitchen and cleaned it with a little swab, then went over to sit by Ann Clayborne and Simon Frazier and the rest of the geologists. Ann looked nearly asleep; she was spending her mornings taking long rover trips and hikes, and then working hard on the base all afternoon, trying to make up for her trips away. To Nadia she seemed strangely tense, less happy about being on Mars than one would have thought. She appeared unwilling to work on the factories, or for Hiroko; indeed she usually came to work for Nadia, who, since she was only trying to build housing, could be said to be impacting the planet less than the more ambitious teams. Maybe that was it, maybe not; Ann wasn’t saying. She was hard to know, moody – not in Maya’s extravagant Russian manner, but more subtly, and, Nadia thought, in a darker register. In Bessie Smith land.

All around them people cleaned up after dinner and talked, and looked over manifests and talked, and bunched around computer terminals and talked, and washed clothes and talked; until most were stretched out on their beds, talking in lower voices, until they passed out. “It’s like the first second of the universe,” Sax Russell observed, rubbing his face wearily. “All crammed together and no differentiation. Just a bunch of hot particles rushing about.”

And that was just one day; and that was what it was like every day, for day after day after day. No change in the weather to speak of, except occasionally a wisp of cloud, or an extra-windy afternoon. In the main, the days rolled by one like the next. Everything took longer than planned. Just getting into the walkers and out of the habitats was a chore, and then all the equipment had to be warmed; and even though it had been built to a uniform set of standards, the international nature of the equipment meant that there were inevitable mismatches of size and function; and the dust (“Don’t call it dust!” Ann would complain. “That’s like calling dust gravel! Call it fines, they’re fines!”) got into everything; and all the physical work in the penetrating cold was exhausting, so that they went slower than they thought they would and began to collect a number of minor injuries. And, finally, there was just an amazing number of things to do, some of which had never even occurred to them. It took them about a month, for instance (they had budgeted ten days) just to open all the freight loads, check their contents and move them into the appropriate stockpiles – to get to the point where they could really begin to work.

After that, they could begin to build in earnest. And here Nadia came into her own. She had had nothing to do on the Ares, it had been a kind of hibernation for her. But building things was her great talent, the nature of her genius, trained in the bitter school of Siberia; and very quickly she became the colony’s chief troubleshooter, the universal solvent as John called her. Almost every job they had benefited from her help, and as she ran around every day answering questions and giving advice, she blossomed into a kind of timeless work heaven. So much to do! So much to do! Every night in the planning sessions Hiroko worked her wiles, and the farm went up: three parallel rows of greenhouses, looking like commercial greenhouses back on Earth except smaller and very thick-walled, to keep them from exploding like party balloons. Even with interior pressures of only three hundred millibars, which was barely farmable, the differential with the outside was drastic; a bad seal or a weak spot, and they would go bang. But Nadia was good at cold weather seals, and so Hiroko was calling her in a panic every other day.

Then the materials scientists needed help getting their factories operational, and the crew assembling the nuclear reactor wanted her supervision for every breath that they took: they were petrified with fright that they would do something wrong, and were not reassured by Arkady sending radio messages down from Phobos insisting they did not need such a dangerous technology, that they could get all the power they needed from wind generation: he and Phyllis had bitter arguments about this. It was Hiroko who cut Arkady off, with what she said was a Japanese commonplace: “Shikata ga nai,” meaning there is no other choice. Windmills might have generated enough power, as Arkady contended, but they didn’t have windmills, while they had been supplied with a Rickover nuclear reactor, built by the US Navy and a beautiful piece of work; and no one wanted to try bootstrapping themselves into a wind-powered system: they were in too much of a hurry. Shikata ga nai. This too became one of their oft-repeated phrases.

And so every morning the construction crew for Chernobyl (Arkady’s name, of course) begged Nadia to come out with them and supervise. They had been exiled far to the east of the settlement, so that it made sense to go out for a full day with them. But then the medical team wanted her help building a clinic and some labs inside, from some discarded freight crates that they were converting into shelters. So instead of staying out at Chernobyl she would go back midday to eat and then help the med team. Every night she passed out exhausted.

Some evenings before she did, she had long talks with Arkady, up on Phobos. His crew was having trouble with the moon’s micro-gravity, and he wanted her advice as well. “If only we could get into some g just to live, to sleep!” Arkady said.

“Build train tracks in a ring around the surface,” Nadia suggested out of a doze. “Make one of the tanks from the Ares into a train, and run it around the track. Get on board and run the train around fast enough to give you some g against the ceiling of the train.”

Static, then Arkady’s wild cackle. “Nadezhda Francine, I love you, I love you!”

“You love gravity.”

With all this advisory work, the construction of their permanent habitat went slowly indeed. It was only once a week or so that Nadia could climb into the open cab of a Mercedes and rumble over the torn ground to the end of the trench she had started. At this point it was ten meters wide, fifty long, and four deep, which was as deep as she wanted to go. The bottom of the trench was the same as the surface: clay, fines, rocks of all size. Regolith. While she worked with the bulldozer the geologists hopped in and out of the hole, taking samples and looking around, even Ann who did not like the way they were ripping up the area; but no geologist ever born could keep away from a land cut. Nadia listened to their conversation band as she worked. They figured the regolith was probably much the same all the way down to bedrock, which was too bad; regolith was not Nadia’s idea of good ground. At least its water content was low, less than a tenth of a percent, which meant they wouldn’t get much slumping under a foundation, one of the constant nightmares of Siberian construction.

When she got the regolith cut right, she was going to lay a foundation of Portland cement, the best concrete they could make with the materials at hand. It would crack unless they poured it two meters thick, but shikata ga nai; and the thickness would provide some insulation. But she would have to box the mud and heat it to get it to cure; it wouldn’t below 13° Centigrade, so that meant heating elements … Slow, slow, everything was slow.

She drove the dozer forward to lengthen the trench, and it bit the ground and bucked. Then the weight of the thing told, and the scoop cut through the regolith and plowed forward. “What a pig,” Nadia said to the vehicle fondly.

“Nadia’s in love with a bulldozer,” Maya said over their band.

At least I know who I’m in love with, Nadia mouthed. She had spent too many of the evenings of the last week out in the tool shed with Maya, listening to her rattle away about her problems with John, about how she really got along in most ways better with Frank, about how she couldn’t decide what she felt, and was sure Frank hated her now, etc. etc. etc. Cleaning tools Nadia had said Da, da, da, trying to hide her lack of interest. The truth was she was tired of Maya’s problems and would rather have discussed building materials, or almost anything else.

A call from the Chernobyl crew interrupted her bulldozing. “Nadia, how can we get cement this thick to set in the cold?”

“Heat it.”

“We are!”

“Heat it more.”

“Oh!” They were almost done out there, Nadia judged: the Rickover had been mostly preassembled, it was a matter of putting the forms together, fitting in the steel containment tank, filling the pipes with water (which dropped their supply to nearly nothing), wiring it all up, piling sandbags around it all, and pulling the control rods. After that they would have three hundred kilowatts on hand, which would put an end to the nightly argument over who got the lion’s share of generator power the next day.

There was a call from Sax: one of the Sabatier processors had clogged, and they couldn’t get the housing off it. So Nadia left the bulldozing to John and Maya, and took a rover to the factory complex to have a look. “I’m off to see the alchemists,” she said.

“Have you ever noticed how much the machinery here reflects the character of the industry that built it?” Sax remarked to Nadia as she arrived and went to work on the Sabatier. “If it’s built by car companies, it’s low-powered but reliable. If it’s built by the aerospace industry, it’s outrageously high-powered but breaks down twice a day.”

“And partnership products are horribly designed,” Nadia said.

“Right.”

“And chemical equipment is finicky,” Spencer Jackson added.

“I’ll say. Especially in this dust.”

The Boeing air miners had been only the start of the factory complex; their gases were fed into big boxy trailers to be compressed and expanded and rendered and recombined using chemical engineering operations such as dehumidification, liquefaction, fractional distillation, electrolysis, electro-synthesis, the Sabatier process, the Raschig process, the Oswald process … Slowly they worked up more and more complex chemicals, which flowed from one factory to the next, through a warren of structures that looked like mobile homes caught in a web of color-coded tanks and pipes and tubes and cables.

Spencer’s current favorite product was magnesium, which was plentiful; they were getting twenty-five kilos of it from every cubic meter of regolith, he said, and it was so light in Martian g that a big bar of it felt like a piece of plastic. “It’s too brittle when pure,” Spencer said, “but if we alloy it just a bit we’ll have an extremely light and strong metal.”

“Martian steel,” Nadia said.

“Better than that.”

So, alchemy; but with finicky machines. Nadia found the Sabatier’s problem and went to work fixing a broken vacuum pump. It was amazing how much of the factory complex came down to pumps, sometimes it seemed nothing but a mad assemblage of them; and by their nature they kept clogging with fines and breaking down.
