Red Mars

“They must be east of here somewhere.”

So they had finally found a job for the geologists that actually helped the construction effort. Ann and Simon and Phyllis and Sasha and Igor drove long-distance rovers over the horizon to east of the base, searching and surveying far past Chernobyl; and in the next week they found almost forty parachutes, each one representing a few hundred kilos of useful nylon.

One day they came back excited, having reached Ganges Catena, a series of sinkholes in the plain a hundred kilometers to the southeast. “It was strange,” Igor said, “because you can’t see them until the last minute, and then they’re like huge funnels, about ten kilometers across and a couple deep, eight or nine in a row, each smaller and shallower. Fantastic. They’re probably thermokarsts, but they’re so big it’s hard to believe it.”

Sasha said, “It’s nice to see such a distance, after all this near horizon stuff.”

“They’re thermokarsts,” Ann said. But they had drilled and found no water. This was getting to be a concern; they hadn’t found any water to speak of in the ground, no matter how far down they drilled: it forced them to rely on the supplies from the air miners.

Nadia shrugged. The air miners were pretty tough. She wanted to think about her vaults. The new improved bricks were appearing and she had started the robots building the walls and roofs. The brick factory filled little robot cars, which rolled like toy rovers across the plain to cranes at the site; the cranes pulled out bricks one by one, and placed them on cold mortar spread by another set of robots. The system worked so well that soon the bottleneck became brick production itself. Nadia would have been pleased, if she had had more faith in the robots: these seemed okay, but her experiences with robots in the years on Novy Mir had made her wary. They were great if everything went perfectly, but nothing ever went perfectly, and it was hard to program them with decision algorithms that didn’t either make them so cautious that they froze every minute, or so uncontrolled that they could commit unbelievable acts of stupidity, repeating an error a thousand times and magnifying a small glitch into a giant blunder, as in Maya’s emotional life. You got what you put into robots; but even the best were mindless idiots.

One evening Maya snagged her out in her tool room and asked her to switch to a private band. “Michel is useless,” she complained. “I’m really having a hard time, and he won’t even talk to me! You’re the only one I trust, Nadia. Yesterday I told Frank that I thought John was trying to undercut his authority in Houston, but that he shouldn’t tell anyone I thought so and the very next day John was asking me why I thought he was bothering Frank. There’s no one who will just listen and stay quiet!”

Nadia nodded, rolling her eyes. Finally she said, “Sorry, Maya, I have to go talk to Hiroko about a leak they can’t find.” She banged her faceplate lightly against Maya’s – symbol for a kiss on the cheek – switched to the common band and took off. Enough was enough. It was infinitely more interesting to talk to Hiroko: real conversations, about real problems in the real world. Hiroko was asking Nadia for help almost every day, and Nadia liked that, because Hiroko was brilliant, and since landfall had obviously raised her estimate of Nadia’s abilities. Mutual professional respect, a great maker of friendships. And so nice to talk nothing but business. Hermetic seals, lock mechanisms, thermal engineering, glass polarization, farm/human interfaces (Hiroko’s talk was always a few steps ahead of the game); these topics were a great relief after all the emotional whispered conferences with Maya, endless sessions about who liked Maya and who didn’t like Maya, about how Maya felt about this and that, and who had hurt her feelings that day … bah. Hiroko was never strange, except when she would say something Nadia didn’t know how to deal with, like, “Mars will tell us what it wants and then we’ll have to do it.” What could you say to something like that? But Hiroko would just smile her big smile, and laugh at Nadia’s shrug.

At night the talk still went everywhere, vehement, absorbed, unselfconscious. Dmitri and Samantha were sure that they could soon introduce genetically engineered micro-organisms into the regolith that would survive, but they would have to get permission first from the UN. Nadia herself found the idea alarming: it made the chemical engineering in the factories look relatively straightforward, more like brickmaking than the dangerous acts of creation Samantha was proposing … Although the alchemists were performing some pretty creative things themselves. Almost every day they came back to the trailer park with samples of new materials: sulphuric acid, sorel cements for the vault mortar, ammonium nitrate explosives, a calcium cyanamide rover fuel, polysulfide rubber, silicon-based hyperacids, emulsifying agents, a selection of test tubes holding trace elements extracted from the salts; and, most recently, clear glass. This last was a coup, as earlier attempts at glassmaking had produced only black glass. But stripping silicate feedstocks of their iron content had done the trick; and so one night they sat in the trailer passing around small wavy sheets of glass, the glass itself filled with bubbles and irregularities, like something out of the seventeenth century.

When they got the first chamber buried and pressurized, Nadia walked around inside it with her helmet off, sniffing the air. It was pressurized to 450 millibars, the same as the helmets and the trailer park, with an oxygen-nitrogen-argon mix, and warmed to about 15° Centigrade. It felt great.

The chamber had been divided into two stories by a floor of bamboo trunks, set in a slot in the brick wall two and a half meters overhead. The segmented cylinders made a sweet green ceiling, lit by neon tubes hung under them. Against one wall was a magnesium and bamboo staircase, leading through a hole to the upper story. She climbed up to have a look. Split bamboo over the trunks made a fairly flat green floor. The ceiling was brick, rounded and low. Up there they would locate the bedrooms and bathroom; the lower floor would be living room and kitchen. Maya and Simon had already put up wall hangings, made of nylon from the salvaged parachutes. There were no windows: lighting came only from the neon bulbs. Nadia disliked this fact, and in the larger habitat she was already planning, there would be windows in almost every room. But first things first. For the time being these windowless chambers were the best they could do. And a big improvement over the trailer park, after all.

As she went back down the stairs she ran her fingers over the bricks and mortar. They were rough, but warm to the touch, heated by elements placed behind them. There were heating elements under the floor as well. She took off her shoes and socks, luxuriating in the feel of the warm rough bricks underfoot. It was a wonderful room; and nice, too, to think that they had gone all the way to Mars, and there built homes out of brick and bamboo. She recalled vaulted ruins she had seen years ago on Crete, at a site called Aptera; underground Roman cisterns, barrel-vaulted and made of brick, buried in a hillside. They had been almost the same size as these chambers. Their exact purpose was unknown; storage for olive oil, some said, though it would have been an awful lot of oil. Those vaults were intact two thousand years after their construction, and in earthquake country. As Nadia put her boots back on she grinned to think of it. Two thousand years from now, their descendants might walk into this chamber, no doubt a museum by then, if it still existed – the first human dwelling built on Mars! And she had done it. Suddenly she felt the eyes of that future on her, and shivered. They were like Cro-Magnons in a cave, living a life that was certain to be pored over by the archeologists of subsequent generations; people like her who would wonder, and wonder, and never quite understand.

More time passed, more work got done. It blurred for Nadia: she was always busy. The interior construction of the vaulted chambers was complicated, and the robots couldn’t help much: plumbing, heating, gas exchange, locks, kitchens; they had all the fixtures and tools and could work in pants and sweatshirts, but still it took an amazing amount of time. Work work work, day after day!

One evening, just before sunset, Nadia trudged across torn-up dirt to the trailer park, feeling hungry and beat and extremely relaxed, not that you didn’t have to be careful at the end of a day: she had torn a centimeter hole in the back of a glove the other evening being careless, and the cold hadn’t been so bad, about –50° Centigrade, nothing compared to some Siberian winter days – but the low air pressure had sucked out a blood bruise instantly, and then that had started to freeze up, which made the bruise smaller no doubt, but slower to heal as well. Anyway, you had to be careful, but there was something so fluid about tired muscles at the end of a day’s construction work, the low rust sunlight slanting across the rocky plain, and all of a sudden she could feel that she was happy. Arkady called in from Phobos at just that moment, and she greeted him cheerily; “I feel just like a Louis Armstrong solo from 1947.”

“Why 1947?” he asked.

“Well, that was the year he sounded the most happy. Most of his life his tone has a sharp edge to it, really beautiful, but in 1947 it was even more beautiful because it has this relaxed fluid joy, you never hear it in him before or after.”

“A good year for him, I take it?”

“Oh yes! An amazing year! After twenty years of horrible big bands, you see, he got back to a little group like the Hot Five, that was the group he headed when he was young, and there it was, the old songs, even some of the old faces – and all of it better than the first time, you know, the recording technology, the money, the audiences, the band, his own power … It must have felt like the fountain of youth, I tell you.”

“You’ll have to send up some recordings,” Arkady said. He tried to sing: “I can’t give you any thing but love, baby!” Phobos was about over the horizon, he had just been calling to say hi. “So this is your 1947,” he said before he went.

Nadia put her tools away, singing the song correctly. And she understood that what Arkady had said was true; something had happened to her similar to what had happened to Armstrong in 1947 – because despite the miserable conditions, her youthful years in Siberia had been the happiest of her life, they really had. And then she had endured twenty years of big band cosmonautics, bureaucracy, simulations, an indoor life – all to get here. And now suddenly she was out in the open again, building things with her hands, operating heavy machinery, solving problems a hundred times a day, just like Siberia only better. It was just like Satchmo’s return!

Thus when Hiroko came up and said, “Nadia, this crescent wrench is absolutely frozen in this position,” Nadia sang to her, “That’s the only thing I’m thinking of – baby!” and took the crescent wrench and slammed it against a table like a hammer, and twiddled the dial to show Hiroko it was unstuck, and laughed at her expression. “The engineer’s solution,” she explained, and went humming into the lock, thinking how funny Hiroko was, a woman who held their whole ecosystem in her head, but couldn’t hammer a nail straight.

And that night she talked over the day’s work with Sax, and spoke to Spencer about glass, and in the middle of that conversation crashed on her bunk and snuggled her head into her pillow, feeling totally luxurious, the glorious final chorus of “Ain’t Misbehaving” chasing her off to sleep.

But things change as time passes; nothing lasts, not even stone, not even happiness. “Do you realize it’s Ls 170 already?” Phyllis said one night. “Didn’t we land at Ls 7?”

So they had been on Mars for half a Martian year. Phyllis was using the calendar devised by planetary scientists; among the colonists it was becoming more common than the Terran system. Mars’s year was 668.6 local days long, and to tell where they were in this long year it took the Ls calendar. This system declared the line between the sun and Mars at its northern spring equinox to be 0°, and then the year was divided into 360°, so that Ls = 0°–90° was the northern spring, 90–180° the northern summer, 180–270° the fall, and 270–360° (or 0° again) the winter.

This simple situation was complicated by the eccentricity of the Martian orbit, which is extreme by Terran standards, for at perihelion Mars is about forty-three million kilometers closer to the sun than it is at aphelion, and thus receiving about 45% more sunlight. This fluctuation makes the southern and northern seasons quite unequal. Perihelion arrives every year at Ls = 250°, late in the southern spring; so southern springs and summers are much hotter than northern springs and summers, with peak temperatures as much as thirty degrees higher. Southern autumns and winters are colder, however, occurring as they do near aphelion; so much colder that the southern polar cap is mostly carbon dioxide, while the northern one is mostly water ice.

So the south was the hemisphere of extremes, the north that of moderation. And the orbital eccentricity caused one other feature of note; planets move faster the closer they are to the sun, so the seasons near perihelion are shorter than those near aphelion; the northern autumn is 143 days long, for instance, while northern spring is 194. Spring fifty-one days longer than autumn! Some claimed this alone made it worth settling in the north.

In any case, in the north they were; and spring had arrived. The days got longer by a little bit every day and the work went on. The area around the base got more cluttered, more criss-crossed with tracks; they had laid a cement road to Chernobyl and the base itself was now so big that from the trailer park it extended over the horizon in all directions: the alchemists’ quarter and the Chernobyl road to the east, the permanent habitat to the north, the storage area and the farm to the west, and the biomed center to the south.

Eventually everyone moved into the finished chambers of the permanent habitat. The nightly conferences there were shorter and more routinized than they had been in the trailer park, and days went by when Nadia got no calls for help. There were some people she saw only once in a while; the biomed crew in its labs, Phyllis’s prospecting unit, even Ann. One night Ann flopped on her bed next to Nadia’s, and invited her to go along on an exploration to Hebes Chasma, some 130 kilometers to the southwest. Obviously Ann wanted to show her something outside the base area; but Nadia declined. “I’ve got too much work to do, you know.” And seeing Ann’s disappointment: “Maybe next trip.”

And then it was back to work on the interiors of the chambers, and the exteriors of a new wing. Arkady had suggested making the line of chambers the first of four, arranged in a square, and Nadia was going to do it; as Arkady pointed out, it would then be possible to roof the area enclosed by the square. “That’s where those magnesium beams will come in handy,” Nadia said. “If only we could make stronger glass panes …”

They had finished two sides of the square, twelve chambers entirely done, when Ann and her team returned from Hebes. Everyone spent that evening looking at their videotapes. These showed the expedition’s rovers rolling over rocky plains; then ahead there appeared a break extending all the way across the screen, as if they were approaching the edge of the world. Strange little meter-high cliffs finally stopped the rovers, and the pictures bounced as one explorer got out and walked with helmet camera turned on.

Then abruptly the shot was from the rim, a one-eighty pan shot of a canyon that was so much bigger than the sinkholes of Ganges Catena that it was hard to grasp. The walls of the far side of the chasm were just visible on the distant horizon. In fact they could see walls all the way around, for Hebes was an almost-enclosed chasm, a sunken ellipse about two hundred kilometers long and a hundred across. Ann’s party had come to the north rim in late afternoon, and the eastern curve of the wall was clearly visible, flooded by sunset light; out to the west the wall was just a low dark mark. The floor of the chasm was generally flat, with a central dip. “If you could float a dome over the chasm,” Ann said, “you’d have a nice big enclosure.”

“You’re talking miracle domes, Ann,” Sax said. “That’s about ten thousand square kilometers.”

“Well, it would make a good big enclosure. And then you could leave the rest of the planet alone.”

“The weight of a dome would collapse the canyon walls.”

“That’s why I said you’d have to float it.”

Sax just shook his head.

“It’s no more exotic than this space elevator you talk about.”

“I want to live in a house located right where you took this video,” Nadia interrupted. “What a view!”

“Just wait till you get up on one of the Tharsis volcanoes,” Ann said, irritated. “Then you’ll get a view.”

There were little spats like that all the time now. It reminded Nadia unpleasantly of the last months on the Ares. Another example: Arkady and his crew sent down videos of Phobos, with his commentary: “The Stickney impact almost broke this rock in pieces, and it’s chondritic, almost twenty percent water, so a lot of the water outgassed on impact and filled the fracture system and froze in a whole system of ice veins.” Fascinating stuff, but all it did was cause an argument between Ann and Phyllis, their two top geologists, as to whether this was the real explanation for the ice. Phyllis even suggested shipping water down from Phobos, which was silly, even if their supplies were low and their demand increasing. Chernobyl took a lot of water, and the farmers were ready to start a little swamp in their biosphere; and Nadia wanted to install a swimming complex in one of the vaulted chambers, including a lap pool, three whirlpool baths, and a sauna. Each night people asked Nadia how it was coming along, because everyone was sick of washing with sponges and still being dusty, and of never really getting warm. They wanted a bath; in their old aquatic dolphin brains, down below the cerebrums, down where desires were primal and fierce, they wanted back into water.

So they needed more water, but the seismic scans were finding no evidence of ice aquifers underground, and Ann thought there weren’t any in the region. They had to continue to rely on the air miners, or scrape up regolith and load it into the soil-water distilleries. But Nadia didn’t like to overwork the distilleries, because they had been manufactured by a French-Hungarian-Chinese consortium, and were sure to wear out if used for bulk work.

But that was life on Mars; it was a dry place. Shikata ga nai.

“There are always choices,” Phyllis said to that. This was why she had suggested filling landing vehicles with Phobos ice, and bringing it on down; but Ann thought that was a ridiculous waste of energy; and they were off again.

It was especially irritating to Nadia because she herself was in such a good mood. She saw no reason to quarrel, and it disturbed her that the others didn’t feel the same. Why did the dynamics of a group fluctuate so? Here they were on Mars, where the seasons were twice as long as Earth’s, and every day was forty minutes longer: why couldn’t people relax? Nadia had a sense that there was time for things even though she was always busy, and the extra thirty-nine and half minutes per day was probably the most important component of this feeling; human circadian biorhythms had been set over millions of years of evolution, and now suddenly to have extra minutes of day and night, day after day, night after night – no doubt it had effects. Nadia was sure of it, because despite the hectic pace of every day’s work, and the way she passed out in sheer exhaustion every night, she always woke rested. That strange pause on the digital clocks, when at midnight the figures hit 12:00:00 and suddenly stopped, and the unmarked time passed, passed, passed, sometimes it seemed for a very long time indeed; and then snapped on to 12:00:01, and began its usual inexorable flicker; well, the Martian timeslip was something special. Often Nadia was asleep through it, as were most of the rest of them. But Hiroko had a chant that she chanted during it when she was up, and she and the farm team, and many of the rest of them, spent every Saturday night partying and chanting that chant through the timeslip – something in Japanese, Nadia never learned what, though she sometimes hummed along, sitting enjoying the vault and her friends.

But one Saturday night when she sat there, nearly comatose, Maya came over and sat against her shoulder for a talk. Maya with her beautiful face, always well-groomed, always the latest in chicarnost even in their everyday jumpsuits, looking distraught. “Nadia, you have to do me a favor, please, please.”

“What?”

“I need you to tell something to Frank for me.”

“Why don’t you do it yourself?”

“I can’t have John seeing us talk! I have to get a message to him, and please, Nadezhda Francine, you’re my only way.”

Nadia made a disgusted noise.
