  After a timeless interval marked only by the gradual dwindling of the sun, Mars loomed out of the dark. Bisesa and Myra peered curiously through the bridge windows.

  The approaching world was a sculpture of orange-red, its surface pocked and wrinkled, with a broad smearing of gray mist across much of the northern hemisphere. Compared to Earth, which from space was as bright as a daylight sky, Mars looked oddly dark to Bisesa, murky, sullen.

  But as the lightship looped around dwindling orbits she learned to read the landscape. There were the battered southern uplands, punctuated by the mighty bruise of Hellas, and to the north the smoother, obviously younger plains of the Vastitas Borealis. Bisesa was struck how big everything was on Mars. The Valles Marineris canyon system stretched around nearly a quarter the planet’s circumference, and the Tharsis volcanoes were a gross magmatic distortion of the whole planet’s shape.

  So much she might have seen had she visited in 1969 rather than 2069. But today Mars’s air was streaked by brilliant white water-vapor clouds. And on one orbit the Maxwell’s path took them right over the summit of Olympus itself, where black smoke pooled in a caldera wide enough to have swallowed up New York City.

  If the scars of the sunstorm were evident on this new face of Mars, so was the handiwork of mankind. The largest settlement on Mars was Port Lowell, an equatorial splash of silver on the fringe of the battered southern uplands. Roads snaked away to all points of the compass, reminiscent of the rectilinear tracery of canals that the last pre-spaceflight observers had imagined they had seen on Mars.

  And amid the roads and the domes were splashes of green: life from Earth, flourishing under glass in the soil of Mars.

  But Myra pointed out more green, a belt of it stretching across the northern plains, and puddled in the great deep bowl of Hellas, a darker, more somber strain. That had nothing to do with Earth.

  Alexei told Bisesa that they would spend a few nights at Lowell. As soon as a surface rover was free she was to travel on, heading north — all the way to the pole of Mars, she learned, with gathering incredulity. She peered down at that dense lid of northern fog, wondering what waited for her beneath its murk.

  They spent a whole day floating above Mars, as the gentle pressure of sunlight regularized the Maxwell’s orbit. Then a squat, boxy craft came lumbering up from Lowell.

  The shuttle’s sole occupant was a woman, perhaps in her mid-twenties. Dressed in a bright green coverall she was slender, rather fragile looking, and her face, open, somewhat empty, bore a neat ident tattoo. “Hi. I’m Paula. Paula Umfraville.”

  When Paula smiled directly at her, Bisesa gasped. “I’m sorry.

  It’s just—”

  “Don’t worry. A lot of people from Earth have the same reaction.

  I’m flattered, really, that people remember my mother so well…”

  For Bisesa’s generation Helena Umfraville’s face had become one of the most famous in all the human worlds: not just for her participation in the first manned mission to Mars, but for the remarkable discovery she had made just before her own death. Paula might have been her double.

  “I’m not important.” Paula spread her arms wide. “Welcome to Mars! I think you’re going to be intrigued by what we’ve found here, Bisesa Dutt…”

  The shuttle’s descent was a smooth glide. As Bisesa watched, the wrinkled face of Mars flattened into a dusty landscape, and ocher light seeped across the sky.

  Paula talked all the way down, perhaps delivering a patter intended to reassure nervous passengers. “I usually find myself apologizing to visitors from Earth — and especially if they’re heading for the poles, as you are, Bisesa. Here we are coming down at latitude ten north, and we’ll have to haul you all the way to the polar cap overland from here. But all the support facilities are here at Lowell, and the other colonies close to the equator, because the equatorial belt was all those first-generation chemical-engine ships could reach…”

  Myra was more interested in Paula than in Mars. She said awkwardly, “I went into astronautics after the sunstorm. Helena Umfraville was a hero of mine — I studied her life. I never knew she had a daughter.”

  Paula shrugged. “She didn’t, before she left for Mars. But she wanted a child. She knew that on the Aurora 1 she would spend months bathed in deep-space radiation. So before she departed she left behind eggs, other genetic material. It was transferred to a Hibernaculum during the sunstorm. And after the storm was over, my father — well. Here I am. Of course my mother never knew me.

  I like to think she would have been proud that I’m here on Mars, in a way carrying on her work.”

  “I’m sure she would be,” Bisesa said.

  The touchdown was brisk and businesslike, on a pad built of a kind of glass, melted out of the crust. Bisesa stared. This was Mars.

  Beyond the scarred surface of the pad everything was reddish-brown, the land, the sky, even the washed-out disk of the sun.

  Within minutes a small bus with blister windows came bouncing up, puppylike, on huge soft wheels. It was painted green, like Paula’s jumpsuit — of course, Bisesa thought, you would use green to stand out on red Mars. Bisesa clambered through a docking tunnel, following Paula, with Alexei and Myra and their luggage and bits of kit. The bus, with rows of plastic seats, might have come from any airport on Earth.

  As the bus rolled off Paula chattered about the landscape. She seemed proud of it, engaging in her enthusiasm. “We’re actually on the floor of a canyon called the Ares Vallis. This is an outflow canyon, shaped by catastrophic flooding in the deep past, draining from the southern uplands.”

  That ancient calamity had lasted just ten or twenty days, it was thought, a few weeks billions of years past when a river a thousand times as mighty as the Mississippi had battered its way through the ancient rocks. This sort of event had, it seemed, occurred all around the great latitudinal frontier where Mars’s south met its north; the whole of the northern hemisphere was depressed below the mean surface level, like one enormous crater imposed on half the planet.

  “You can see why the Aurora crew were sent here for the first human exploration — and in fact why NASA sent its Pathfinder un-manned probe to the same area in the 1990s…”

  Bisesa, peering out, tuned out the words. This dusty plain, littered with slablike boulders, was Earthlike, and yet immediately not Earthlike. How strange it was that she could never touch those dusty rocks, or taste that thin iron air.

  As they neared the domes of Lowell they passed cylinders mounted vertically on tripods. To Bisesa they looked like the power lasers of a space elevator. The Martians didn’t have their beanstalk yet, it seemed, but they had the power sources in place.

  And the bus rolled past flags that fluttered limply over markers of Martian glass. Bisesa supposed Paula’s mother was here, with those others of Bob Paxton’s crew who had not survived their stranding on Mars. If Ares’s geology was forever shaped by that tremendous flood in the deep past, so its human history would surely always be shaped by the heroism of the Aurora crew.

  The bus drove them up to the largest of the domes and docked smoothly.

  They passed through a connecting tunnel and emerged in a warren of internal partitions, lit by big fluorescent tubes suspended from a silvered roof. Bisesa felt very self-conscious as she walked into the dome, practicing her Mars lope. The noise levels were high, echoing.

  People bustled by, many dressed in green jumpsuits like Paula’s. They all seemed busy, and few of them glanced at Bisesa and her party. Bisesa guessed that to these locals she would be about as welcome as tourists at a South Pole base on Earth.

  Alexei felt moved to apologize. “Don’t mind this. Just remember, every breath you take has to be paid for out of somebody’s taxes…”

  Bisesa did notice that very few of the Martians wore ident tattoos on their cheeks.

  They dumped their luggage in rooms provided for them in a cramped, shacklike “hotel,” and Paula offered to fill their few hours at Lowell wi
th a tour. So they went exploring, following Paula, working their way from dome to half-inhabited dome through tunnels that were sometimes so low they had to crouch.

  They bought their own lunch at an automated galley. Their Earth credit was good, but the bowls of sticky soup and bitter coffee they bought were expensive.

  As they ate, a gang of schoolkids ran by, laughing. They were skinny, gangly, all at least as tall as Bisesa, though with their slim bodies and fresh faces it was hard to tell how old they were. They ran with great bounds.

  Alexei murmured, “First-generation Martians. Grown from conception under low gravity. The next generation, their children, will be very interesting…”

  Bisesa was sorry when they had passed out of sight, taking their splash of human warmth with them.

  One big translucent dome enclosed a farm. They walked between beds of lettuces and cabbages, all proud and healthy, and shallow ponds that served as rice paddies, and trestle tables bearing pans of some turgid fluid from which grew beans and peas and soya. There were even fruit trees, oranges and apples and pears growing in pots, obviously precious and lovingly tended. In here they were at last exposed to pink Martian daylight, but the light of the remote sun was supplemented by banks of hot white lamps.

  But they walked on quickly. Under a faint scent of some industrial perfume was the cloying stench of sewage.

  They reached the dome’s translucent wall, and Bisesa saw rows of plants marching away, set into the soil beyond the dome. She noticed how they glinted, oddly glassy, and the green of their oddly shaped leaves was a deeper shade than the bright plants around her.

  But she wasn’t yet used to Mars. It took a beat before it struck her that these rows of plants were happily growing in the Martian air outside the pressurized dome. “Oh, my,” she said.

  Alexei laughed.

  They walked on through more inhabited areas. They passed what had to be a school, and Bisesa longed to walk in and discover what kind of curriculum was presented to these first young Martians — what were they told of Earth? — but she didn’t have the nerve to ask Paula.

  And they found a bar, called “Ski’s”—apparently after Schia-parelli, inadvertent discoverer of the Lowellian canals. There was alcohol available, but only fruit wines and whiskeys. They tried an apple wine, but it tasted weak to Bisesa.

  “Low gravity, low pressure,” Alexei said. “It’s easier to get drunk here.”

  The last dome they explored was the largest, and looked the most expensive. It was constructed of panels laid over immense struts of what Myra identified as lunar glass. The interior was mostly disused. Aside from a few corners used for stores and small workshops, there were only dusty partitions, cables, and ducts lying over an unfinished floor.

  “It’s as if they don’t quite know what to do with it,” Bisesa said.

  “But it wasn’t the Martians’ choice,” Paula said. “After the sunstorm there was a lot of sentiment about what happened to the Aurora crew, and a lot of money was put into getting the Mars settlement going properly. And this was one result. It was going to be a slice of Earth, here on Mars.” She waved a hand. “Those glass struts came from the sunstorm shield itself. So this is a sort of memorial, you see. There would have been blue sky, projected onto that big dome. They were going to call it Oxford Circus.”

  “You’re kidding.”

  “No,” Alexei said. “There was even going to be a zoo here.

  Farm animals. Maybe an elephant or two, Sol, I don’t know. All shipped up as zygotes.”

  “And weather, like Earth’s, inside the dome,” Paula said.

  “They even got that part of it working for a while, when I was little. The thunderstorm was quite scary. But it all broke down and nobody bothered to fix it. Why should we? Many of us have never seen Earth; we don’t miss it. And we have our own weather.” She smiled wider, her young face so like her mother’s, her eyes blank.

  That night, Bisesa settled down in a stern monkish cell that seemed designed to remind her that she wasn’t a guest here, not welcome, that she was here on sufferance.

  But there was a row of books above her bed — real paper books, or anyhow facsimiles. They were editions of classic novels of Mars as it had been dreamed of during the long years before spaceflight, from Wells through Weinbaum and Bradbury to Robinson and beyond. Flicking through the old books oddly pleased her; for the first time since she had arrived, she was reminded how many dreams had always been lodged on Mars.

  She clambered into bed. She read a few chapters of Martian Dust by a writer called Martin Gibson. It was a colorful melodrama that, with the comforting gravity, soon lulled her to sleep.

  19: The Sands of Mars

  She was woken by Alexei, shaking her shoulder. “We have to move.”

  She sat up, rubbing her eyes. “I thought you said we have to wait for a rover.”

  “Well, we changed our plans. They don’t have too many assets on Mars, but they started to move during the night.”

  “Who is they?”

  “Astropol. The Space Council. Look, Bisesa, we’ll have time to discuss this. Please, right now you need to shift your ass.”

  She had trusted him, and Myra, this far. She shifted.

  The rover, trundling to its docking port on the central dome, was visible through a small window. The rover had a number: it was the fourth of Lowell’s fleet of six such long-distance exploratory vehicles.

  But it also had a name, stamped in electric blue on its hull: Discovery.

  About the size of a school bus, painted bright green, its hull bristled with antennae and sensor pods, and a remote manipulator arm was folded up at its side. The rover dragged an equally massive trailer at its back, connected to the parent by a thick conduit. The main body and the trailer were mounted on big complicated-looking wheels on loosely sprung axles. The trailer contained stores, spares, life support gear — and, unbelievably, a small nuclear power plant.

  This rover was big enough to carry a crew of ten on a complete yearlong circumnavigation of Mars. Bisesa realized it was wrong to think of it as a mere bus. It was a spaceship on wheels.

  And it had pressure suits stuck to the outside of the hull. Bisesa said, “Reminds me of Ahab strapped to the side of his whale.”

  But none of them, not even Myra, had heard of Moby Dick.

  “So why Discovery? For the old space shuttle?”

  “No, no. For Captain Scott’s first ship,” Paula said. “You know, the Antarctic explorer? We use this particular rover for polar jaunts, north and south, so the name seems appropriate.”

  Expeditions to the poles had always been a tradition of Lowell Base, Paula said. The astronauts of Aurora, in fact, in their long years as castaways before the sunstorm, had made expeditions to the south pole, intent on coring the ancient ices and so deciphering Mars’s climatic history.

  Paula’s bright chat filled the time as they waited for access to the rover. But Alexei bit his nails, desperate to be away.

  At last hatches swung open. They walked through an airlock and clambered into a roomy interior. There was even a small medical area, complete with robotic arms capable of manipulating a set of surgical instruments.

  Paula said, “We’ll cover around a quarter of the planet’s circumference, traveling twenty hours a day at a nominal fifty klicks per hour. Five days should see us home.”

  “Twenty hours a day?”

  Myra and Bisesa exchanged glances. They had already been cooped up for weeks on the elevator and aboard the Maxwell. But these Spacers were used to lengthy confinement in small places.

  “The Discovery will do the driving itself, of course. It’s done the route a dozen times already, and probably knows every boulder and ice field. It’s a smooth ride once we’re underway…”

  Paula briefly spoke to a traffic control center, and then the rover briskly popped itself loose of the dome airlock.

  Once they were sealed in Alexei sat and blew air through pursed lips. “Well, that’s that
. What a relief.”

  Myra glanced back at the Lowell domes. “Couldn’t we be chased?”

  Alexei said, “The other rovers are out in the field. Mars is still very sparsely populated, Myra, sparsely equipped. Not a good place to mount a car chase. And it’s unlikely that Astropol and the other agencies have any assets at the polar base.” Bisesa had learned that Astropol was a federation of terrestrial police agencies dedicated to offworld operations. “Oh, they could come after us,” Alexei murmured. “But it would take something drastic to do it. They may not be ready to show their hand just yet.”

  The rover swung itself around and set off to the north.

  Bisesa and Myra sat up front behind a big observation window, and watched the view unfold. It was about midday, and the sun was to the south behind them; the rover’s shadow stretched ahead.

  The domes of Lowell soon slipped behind the rear horizon, obscured by the rover’s immense rooster-tails of dust. The road was metaled at first, glassy; then it was hard-pressed dirt, a scar in the faded dust, and before long nothing but a rutted track. Away from the base there was no sign of human activity, save for the odd weather station, and those endless rutted tracks peeling off to the north. Bisesa could make out the remnants of the Ares flood in the scoured landscape, the teardrop islands, the huge scattered boulders. But everything was old, worn down with age, every rock surface rubbed smooth, every slope draped with thick dust.

  With nothing to see but rocks, Myra soon went to join Alexei and Paula, who had a common interest in an exotic form of poker.

  Bisesa sat alone in the bubble rover’s blister window, riding smoothly over Mars. As the sun wheeled through the sky, Mars began to work a kind of spell on her. It was like Earth, with some of the furniture of an earthly landscape: the land below, the sky above, the dust and the scattered rocks. But the horizon was too close, the sun too small, too pale. A corner of her hindbrain kept asking: how can the world be like this?

  It was in this mood of strangeness that she saw the arch.
