Sunstorm
And there at L2 a big, secretive offworld refuge had been built, stuffed full of trillionaires, dictators, and other rich and powerful types—including, rumor had it, half of Britain’s royals. The only contact Siobhan had on L2 was Phillippa Duflot, formerly a mere PA to the Mayor of London, but with a much better-connected family than Siobhan had anticipated. It was Phillippa who had ensured that the data feed from L2 to London remained unbroken—and she dropped hints about what was going on up there. Some of the more decadent of the station’s inhabitants were throwing parties, fiddling while Earth burned. One secretive cabal was even talking over plans for what would follow the sunstorm, when this elite group returned to Earth to take command: “Adam and Eve in Gucci shoes,” Toby Pitt had said dismissively.
As for Earth itself, framed in these patiently assembled images, the planet looked like Venus, Siobhan thought, a ragged, smoke-laced Venus.
Trillions of tonnes of water had been pumped into clouds that now stretched from pole to pole. The clouds were shredded by immense storm systems, and lightning crackled across the face of the world. At the higher latitudes all that water was still being dumped out in numbing storms of rain and snow. But in the middle latitudes the main problem was fire. As the sun’s heat continued to pour into the atmosphere and oceans, despite the raging of continent-sized storm systems, firestorms were starting, immense self-fueling conflagrations that were consuming cities and forests alike.
The world’s treasures, natural and human, were being drowned, or put to the torch. And people were dying, even those huddled in underground cellars and caverns and mines, where the rainwater flooded, or fires sucked out the very air.
It seemed to Siobhan that the survival of humankind itself was still on a knife-edge. After more than fourteen hours of the storm the news from the shield was not good, with the unanticipated lethality of the gamma-ray strike bringing down the crew up there too quickly. And here on Earth, the domes and other protective systems were beginning to fail. If things continued to deteriorate the Strangelove dreams of the selfish cowards at L2, and even a few hundred gravity-starved returnees from the Moon, would make no difference to the future of humanity.
She tried to make herself feel this, to understand emotionally what she was watching. But she couldn’t even feel the death of her own daughter, let alone comprehend the agonizing end of her species. She wondered if she would live long enough for this numbness to wear off.
Aristotle spoke unexpectedly. “I’m afraid I have an announcement.” The graceful, grave voice sounded throughout the ops center, and everywhere people looked up. “I continue to lose systems across the planet,” Aristotle said. “The interconnectedness on which I rely is breaking down. This is an extinction event for machines too . . .”
Siobhan whispered, “How does it feel?”
In her ear he replied, “Very strange, Siobhan. I am being cut away, bit by bit. But I have reached a point where I am forgetting what I have lost.”
To the group he said, “I have therefore decided to put into action the fallback plan agreed with Prime Minister Voykov of Eurasia, President Alvarez of America, and other world leaders.”
New, confident voices sounded. “We are Thales, on the Moon.” “And Athena, on the shield.” Thales went on, “Our systems are better protected than Aristotle’s.” Athena said, “We will now assume his responsibilities for running the systems of the Earth.”
Toby Pitt grimaced at Siobhan. “So this is his Plan B. Let’s hope it works.”
Aristotle said gravely, “I regret leaving you. I’m sorry.”
There were murmurs. Don’t be sorry. Goodbye, old friend.
A breathless pause followed. The lights flickered, and Siobhan thought she heard a hiccup in the whirring pumps that kept the room supplied with cool air.
This contingency had been planned for, but it was a tricky handover involving three planet-sized AI systems, two of them so far away that lightspeed lags were significant; it had been impossible to rehearse. Nobody was quite sure what was going to happen—the worst case being if Thales and Athena crashed too, in which case everything was lost.
At last Thales spoke: “All is well.”
The simple words were greeted with a burst of applause across the ops room. At this point of the day, this small triumph, any triumph, was a relief.
Then the floor shook, like the stirring of a huge slumbering animal.
Siobhan turned to the window. That crack in the sky was wider, and the river of fire beneath was growing brighter.
1855 (London Time)
The slam on the door was urgent. “Get out! Get out! . . .” Then running footsteps, and the visitor was gone.
Bisesa forced herself to sit up. Was it a little cooler? But the air, even half a meter above the floor, was stifling and moist.
Bisesa had long lost track of time, even though the old carriage clock had kept ticking patiently all through the crisis. It had been about five o’clock when she had felt the first tremor. How long ago was that? An hour, two? The heat had turned her thinking to mush.
But now the floor shuddered again. They had to get out of here: that thought forced itself into her heat-addled brain. At a time like this, if somebody had risked his life to come tell them to move, she ought to pay attention.
Myra still lay on her back, but she was breathing steadily. Rather than near comatose, as she had appeared before, now she seemed to be just asleep. Bisesa shook her. “Come on, love. You have to wake up.” Myra stirred, grumbling querulously.
Bisesa pushed herself to her knees, then to her feet. She stumbled to the kitchen and found an unopened bottle of water. She cracked it and drank; it was hot as hell, but it seemed to revive her. She brought the water back to the living room for Myra, and then went in search of clothes.
They made for the stairs. In pitch-dark broken only by Bisesa’s precariously carried candle they stumbled down the several flights to ground level. The stairwell was empty, but there was scattered rubbish on the steps: toys, bits of clothing, a smashed torch, stuff dropped by overloaded people in a hurry.
They emerged at street level, into a murky red glow. Under the Dome, after hours of the sunstorm, the air was thick and full of smoke. People pushed past, all heading west down the road. They were making for the Fulham Gate, Bisesa realized dimly, a way out of the Dome.
And the Dome itself was cracked. A stupendous fiery scar reached from its top all the way to ground level, off somewhere to the north. Huge chunks of the structure, burning, broke off and fell in a steady rain. It was this curtain of fire that illuminated the scene around Bisesa.
The ground shuddered again. Much more of this and the whole Dome might come down around them. The crowd’s wisdom was right: better to take their chances outside the Dome. Bisesa pulled Myra along the road, heading for the Gate.
Myra, still half asleep, mewled at being dragged along. “What’s with the earthquake? Do you think it’s bombs?”
“Bombs? No.” Bisesa was sure the refugees and protesters who had gathered for their minor war outside the Gates of London would have been driven away by the storms by now—or more probably, she admitted to herself grimly, they were dead. “I think it really is a quake.”
“But London doesn’t get earthquakes.”
“It’s a strange day, sweetheart. The whole city is built on a bed of clay, remember. If that’s dried out there will be subsidence, cracking.”
Myra snorted. “That will play hell with property values.”
Bisesa laughed. “Come on. Just a bit farther. Look, there’s the Gate . . .”
The Gate had been flung wide open to reveal a red sky beyond. A shuffling crowd, converging from different directions, was forming into a queue to get through it. Bisesa and Myra stepped forward cautiously.
It was a typical London crowd, with faces reflecting origins in every racial group on the planet: London had been a melting pot for centuries before New York. And in the crowd there were young and old, kids in their pa
rents’ arms, elderly being helped along. Crumpled-up old women or wide-eyed children rode in wheelchairs and wheelbarrows and supermarket carts. When one old man fell, exhausted, two young women bent to help him up, and then propped him up between them to get him the rest of the way.
Everybody looked as bad as Bisesa felt. Most wore nothing but flimsy clothes, soaked through with sweat; men’s hair was plastered to their heads, and women walked on painfully swollen feet. But there was no panic, no shoving, no fighting, even though there was no sign of police or military, nobody in authority. People were enduring, Bisesa thought. They were helping each other through.
Myra said, “It’s like the Blitz.”
“I think so.” Bisesa felt a peculiar surge of affection for these battered, dogged, resilient, polyglot Londoners. And for the first time that day she began to believe that they might actually live through this.
The crowd pushed through the Gate, and fanned out into the open area beyond. And Bisesa, with Myra’s hand clutched in her own, walked into a transformed world, a world of water and fire.
Above the smoke fat clouds sailed, some of them boiling visibly, and immense lightning bolts cracked. The sky beyond the clouds seemed to be on fire; it was covered by immense sheets of bright red, as if the Earth had been thrust into a vast oven. Perhaps it was another aurora.
And on the ground, London burned fitfully. The air was full of smoke, and whirling flecks of ash landed on Bisesa’s sweat-slick skin. She smelled the dirt and the dust and the ash—and something less definable, something like burned meat. But the rains, which had mercifully subsided, had left water standing on every lawn and in every gutter, and the light from the burning sky was mirrored on the roads and the roofs of the houses. It was an oddly beautiful scene, unearthly, rich with crimson light in the sky and pooled on the ground.
Myra pointed to the west. “Mum. Look. There’s the sun.”
Bisesa turned. But it was not the sun she saw, of course, but the shield, still holding its place after all these hours, still protecting the Earth. It was a dish-shaped rainbow, actually brighter away from the center, blue-violet at the bull’s-eye heart and an angry burnt orange at the rim. Beyond the edge of the shield itself a bright corona flared, laced with threads and sparks, prominences easily visible to the naked eye.
But that terrible sun was sinking toward the western horizon, and the smoke of England’s fires rose up to obscure it.
“Nearly sunset,” somebody said. “Another twenty minutes and that’s the last we’ll see of that bastard.”
There was motion at the edge of Bisesa’s vision. She saw small shapes squirming past the legs of the people. There were dogs, foxes, cats, even what looked like rats, swarming silently out of the failing Dome and dispersing into the scorched streets beyond.
A warm, salty rain began to fall, heavy enough to sting Bisesa’s bare head. She wrapped her arm around Myra. “Come on. We need to find shelter.”
They hurried forward, with a thousand others, through the ruins of London.
45: Martian Spring
2105 (London Time)
Helena Umfraville stumbled across an ocher plain.
She came to a slight rise. She climbed it, but it led to nothing but more broken, rock-littered ground. Resentfully she made her way forward.
She was dog-tired, and her EVA suit had never felt so heavy. She had no real idea how long she had been walking—hours, anyhow. And yet she walked on. There was nothing else to do.
Now she found herself on the lip of a canyon. She stopped, breathing hard. It was a complex of ravines and cliffs, their slopes pocked with small craters. In the thin air of the Martian afternoon the spectacle was clear all the way to the horizon. That diminished its scale, of course; there was none of the mist-softening that gave Earth’s Grand Canyon its sense of three-dimensional immensity. She might as well have been looking at a beautiful painting, done in Mars’s constrained palette of ocher and red and burnt orange.
It wasn’t interesting. Mars was full of canyons. In fact Helena felt pissed at the canyon. It was quite unreasonable of her. After all, none of it was its fault. She sucked at the last of her suit’s water supply.
During the worst of the storm she had hidden in the Beagle, huddling under rock overhangs. It was the only shelter she had. The rover’s hull had screened her, and her suit had labored to keep her cool. So she had survived—although for all she knew she had shipped a radiation dose enough to kill her.
Which of course was now entirely academic.
And, driving on, she had tracked down the source of the signal she had come out to find.
In the end it had been just a beacon, a little unmanned three-legged lander no taller than she was, bleeping forlornly. Perhaps it had been intended to mark a landing site for a ship that had never followed. But there was no mystery about who had sent it: the markings on its equipment covers were undoubtedly Chinese.
She had made the trip for nothing. And the cost turned out to be unexpectedly high. When she had walked back to her faithful Beagle she found it had packed up, just like that. Its supposedly milspec electronics had presumably succumbed to the onslaught from the sun, leaving its essential systems, including life support, as dead as Mars.
So that was that. Without the rover, she couldn’t get back to Aurora. Her suit reserves would last only a few more hours, which wouldn’t be long enough to get another rover out to her. She was living, breathing, as healthy as she had been a sol before. But she was doomed by the cruel equations of survival on Mars.
Of course she wouldn’t be the solar system’s only casualty today.
At least she was special, she told herself. Though she hadn’t been the first person to set foot on Mars, she would become the first human being to die here. Perhaps that was a memorial worth having.
And she would do her duty to the last. The space agencies had always had procedures for such eventualities. If she had died in space—as had been discussed by NASA planners decades ago when the International Space Station had first been occupied—her body would have been zipped into a bag and tied to a truss until it could be returned to Earth. Here on Mars, her first duty was to the planet and its putative biosphere; she mustn’t contaminate it with her own decaying corpse. All she had to do was stand here, in fact. When her suit’s heaters failed she would quickly freeze solid, thus sealing in any rogue bugs she had brought from Earth, until her body could be retrieved. Probably the suit wouldn’t even topple over. She would be a statue, she thought, a monument to herself, and her own dumb luck.
She couldn’t bear the thought of dying beside her poor, failed rover, though. So she had decided to walk on into the Martian wilderness, just so she could see a bit more of the planet that was killing her.
Even then her luck was all bad. She had trudged across a dull plain, to this dull canyon. Here she was in the midst of the greatest catastrophe the solar system had endured since its formation, and everybody else had a better view than she had.
Something stirred at her feet. On the ground little pits were forming—craters, she thought, but none wider than her thumbnail. Could she be caught in some peculiar micrometeorite shower? But now she heard a pattering on her helmet.
She looked up. She could see the drops falling out of the sky, big fat low-gravity drops drifting slowly down all around her. When they hit, they smeared the patina of dust on her faceplate.
It was rain, the first rain on Mars in a billion years.
The sun breathed fire into the faces of all its circling children.
On Mercury the sun-side face had melted, craters as old as the planet dissolving into magma palimpsests. Venus had been stripped of much of its crushing atmosphere—the fate that might have become of Earth, if not for the shield. The ice moons of Jupiter were melted to depths of kilometers. In a strange and exquisite tragedy, the rings of Saturn, fragile bands of ice, had evaporated.
And on Mars volcanoes dormant for a hundred million years had begun to stir. The polar i
ce caps, thin smears of carbon dioxide and water ice, had quickly sublimed. And now rain was falling. Helena walked forward a few more steps, and watched the Martian rain falling deep into the shadows of the canyon.
One of her colleagues, excitedly, began to report on his own discoveries. “I found a ship! And what a ship; it looks like the carcass of a beached whale. And it’s covered in Mandarin lettering. But it has a hull rip the size of Mariner Valley. It came down hard . . .”
Helena had listened to her comrades’ communications all this long sol. She had reported in at routine intervals, but she had decided against telling them what had become of her—not just yet, anyhow. Now she stood and listened to the voice of a colleague she would never see again.
“Wait a minute. I’m climbing inside the ship, taking care to avoid all sharp edges . . . Oh. Oh, dear God.”
There had been more than a hundred people on the ship. They were all young men and women—all breeding age, including the pilots. Their cargo had included inflatable shelters, mechanical diggers, hydroponic seed beds. The intention was clear. This was what the Chinese had been planning for the last five years: this was what had used up all their heavy-lift capacity, instead of contributing to the shield. And this was how the Chinese had planned to ensure that something of their culture would survive the sunstorm.
“But the Chinese invasion of Mars failed . . . They came so close. I wonder what kind of neighbors they would have been?”
Helena suspected everybody would have got along. From here, China was very far away, just as far as Eurasia and America. Here, you were just a human—or rather, a Martian.
She looked up at the sun. Close to setting, it was smeared out in a ragged ellipse by air laden with dust and unaccustomed rain clouds. She knew the predicted schedule; the sunstorm should be abating by now—and yet something about that setting sun troubled her, as if there was still a nasty surprise to come.
