How to terraform Mars. Easy. Stick a roof over Valles Marineris. Real greenhouse effect. By the time it is complete, it will be visible from Earth, a bright white mote in the eye of the ancient red war god.
Higher now, past the littler, lower moon. Keeping precise pace with it on the other side of the planet is the SkyWheel, the spinning ground-to-orbit space-cable. All the humans, all the machines that build the bases and plants and the machines, were spun down this cable. But the real work of terraforming, the RO in the ROTECH, is done from orbit. Up beyond the vanas and the supercores, weaving a magnetic cocoon around this tectonically dead, defenseless world, are the orbital habitats and factories and mass drivers of the planetary engineers and terraformers. By the time humans can walk unclad under the Grand Valley roof, they will form a ring around the planet, a band of satellites. The night will glitter with them.
All in a construction worker’s visor; reflected.
Ashwin Mehta edges the heavy-lift flotilla in over the construction site. His belly sensors and satellite uplinks to ROTECH’s moon ring redoubt could guide him in with laser precision but human atavism endures. The gloved hands wave him down, and he follows. Spinners skitter clear. The winds that howl the full length of the rift valley have buried the load with sand: Ashwin’s trim-fans sweep it clear as he maneuvers with millimeter precision. He feels the lift cables go out of him: it is a physical, pleasurable sensation but not one for which his flesh body has an analogue.
Despite Bharat trumpeting the largest IT skill pool on the planet, Ashwin knows that he and every other body on its live-skin couch only got there because of strong body mapping. It still took him many shifts to feel his way into a new, weightless body to which modules could be added or swapped. His hands and arms are obviously the wiry little manipulators—though no human arm ever experienced the sensation of detaching itself and swinging, hand-over-hand to a new attachment point elsewhere on the body. His legs he regards as the fan-pods, his lungs the lift bags and the curved silver shell his body, the center of his being. The slave units, hooked up according to work schedule, were more difficult, but he has learned a way; he expands his sense of self to incorporate them. I am vast, I contain multitudes. It still takes some minutes after the computers flick him home at light-speed to snap out of three-hundred-sixty-degree vision. The rabbit-eye sight of his hundreds of optical sensors has taught Ashwin truths about how body shapes consciousness. The universe of meat is divided rigidly into front and back, visible and invisible. Objects are sought out, selected, made part of the view. Morphology begets psychology. Ashwin, like a divinity, sees everywhere at once. There is no forward or backward, up or down, just movement toward a destination or away from it.
It is this aspect of his job that he finds hardest to tell others. His parents nod and say how good it is that he has employment and good steady money but they do not comprehend what he is doing up there, let alone how he feels doing it. They are one generation away from believing that gods live in the sky. He does not want to tell them that, in a sense, they do. The girls are a little more sophisticated; they know about other planets and terraforming. Mars! How exciting! How romantic! Is it really really dangerous? Do you face sandstorms and explosions and volcanoes? Telling them that Mars is a quiet, placid sort of place, where what action there ever was happened billions of years ago, is not what they want to hear but they have passed on anyway, for these women also know what kind of work the corporadas hire for, and how little it pays.
He feels locked. The cable grippers bind molecule to molecule with the lift points. Ready, Ashwin says. Coprates control whispers clearance in his inner ear: the site foreman waves her hand. Take her up. Fans swivel to full lift. Winches wind in the strain. Flicker-lasers torch up: these loads require every gram of lift. Ashwin feels motor/muscles tense, strut-bones strain. He mentally grits his teeth. You are a weight lifter, going for the clean lift.
The rosette of twelve linked LTAs pulls the five-hundred-meter diameter glass hexagon clear from the sand. Ashwin lifts straight for a hundred meters, then tilts the whole array from side to side to clear it of lingering dust and dead glass-weavers. Gently, gently. The glass is engineered to tolerances far beyond terrestrial norms, and the gravity slight, but one crack, three kilometers up. ... Tiny crystal shells cascade from the edges of the roof pane like iridescent snow. The great glass light heliographs in the sun. The forewoman raises an arm in salute as Ashwin gains cruising altitude. It is a sight he never tires of, this resurrection of glass from the earth. Two kilometers up, bearing 5.3 pi rad, Pier 112, 328. Pane 662, 259.
Telephone number engineering.
Beneath him graders are leveling billion-year-old outwash hills for new glass fields. Ahead, the buried panes are stains in the sand, a mesh of linked hexagons. Tiny machines, working, working. Ashwin reflects a moment on the incomplete dome of Kharar railway station, then a proximity alert gently chides him: Heavy Lift Array 2238 is on approach to pick up. Day and night the LTAs carry and set, busy and sterile as drone bees.
In the air lane now. The lifters move in strictly regulated traffic zones over cleared terrain. There has not been an accidental drop since Ashwin started on the job, but a five-hundred hexagon of fifty-centimeter glass falling from three kays is the stuff of health and safety legend. HLA 1956 comes up from the glass fields of Gander and slips in ahead of Ashwin: a colleague, though Ashwin has never seen his flesh face, nor knows where his meat is based. He sends a greeting message over the com channels; truckers flashing their headlights. Closing on the target now. The front edge of the construction is visible as a line of white light. Ashwin has never seen the sea, but he always thinks of the edge of the world roof as a line of surf breaking on a beach, frozen, turned to slow-flowing glass, inching forward day by day, hour by hour. One kilometer out, construction control taps into Ashwin’s neural matrix and dispatches him and his load into an approach pattern to Pier 112, 328. As he moves in high over the open fingers of the Main Left Branch, he sees another heavy-lift cluster retract cables and slide away from the pier top. Spider-welders skitter across the glass on delicate sucker feet to bolt the plate to the struts. That is what Ashwin’s friend from Senegal does: Ashwin can see his spider-welder hugging the pure white spar like a tick as he swivels the rig on its belly fans. They earn more than lifter pilots. They have more responsibility.
Lasers flicker from all around Ashwin’s multiple body—another sensation for which his meat has no likeness—guiding him in onto the baffle plates. The alignment must be millimeter perfect. Ashwin tunes the ducted fans to compensate for an unseasonable breeze he can feel picking up across his sensory skin, descends steadily through the mesh of laser light. Thirty meters. Twenty.
Looking good, Ash, says the bolter from Senegal on the innercom.
Ten meters.
Looking good. A simple expression of solidarity, but it opens Ashwin’s extended senses like a key. From skin to horizon in every direction he can look, his world rushes in on him. He sees it all fresh, entire, as one thing. The stupendous canyon, one end to the other, wall to wall. The thin pink sky, the wisps of high cirrus. The surface three kilometers beneath him; the constructions of man, the patterns they make on the soil as they fuse sand to glass. The machines: those above, those below, those between, that crawl upon the pillars and roof of the world. The SkyWheel on its ponderous orbits, ROTECH’s habitats wheeling overhead in a carousel of satellites. The men and minds that looked on this world, and set their will upon it. He sees it all, and it looks good to him. Very good indeed. He is so proud of all that he is part of, this Bharati boy one foot out of the chawl, who is become Creator of Worlds.
Five meters.
And in that instant, everything goes white. ...
Is this what it is to be dead? he thinks and thinking so, knows himself to be alive. An image: the holy woman, buried alive for righteousness’ sake. Real? Imaginary? Is the darkness of the grave really a white so intense it cannot be regarded by the eye? Is there any
difference between outside and inside in this featureless white? A freezing thought. This is the pure white light of cyberspace. There has been an error in the mindlink, a fault in the tap-head technology. The kind of thing that sends some people thrashing and fitting on their couches. You, it has sent into nowhere. No thing. A mind without a body.
He cannot tell if he has flesh perception or machine sense: everything in every direction looks the same and therefore robs him of dimension. An uncle driven blind by cataracts once told him the horror of blindness. It is not not seeing. It is everything white.
A mind, with no senses, no connection to the outside world. He could be lying on his couch at the Ambedkar corporada, in a hospital, at home. A mind with only its own thoughts for company. A thought to make the heart kick coldly in the chest. At least, he can still feel. And if he can feel ...
“Hello?” Ashwin ventures. He can hear himself. His own voice, inside, and outside. “Hello? Can anyone hear me?”
Does he hear an echo, or is it the resonance of his own skull? If he does, is it in another voice, another accent?
“Hello?”
Hello.
And the white: is it moving, are there shapes within it, like figures in a fog? Ashwin is sure now; the fog boils like milk and he can sense up and down, forward, back. Dimensions. Gravity. Slowly he becomes aware that he has a body, his own body, his home flesh. There is a surface under his feet, and there is a human shape walking toward him through the white fog. A white man in a white fog, an old man, dressed for cold, with a compass in his hand. He steps into clear focus and frowns at Ashwin.
“Who the hell are you?” he says.
A milky blue box on a living-room table. A photonic array tumbling over Terra Tyrrhena. Calculations made in billions of parallel universes. Each computer contains the other, and millions more besides.
The machines that are building Mars have more than just the viewpoint of gods. They have something of the power. Quantum computing, quantum engineering. If calculations can be made in multiple universes, one of which supplies the perfect solution, how much simpler to cut out the application of that answer and cut straight to the result? It’s mere extension of theory into practice to take those solutions out of the abstract into the real world. Model a thousand, a million, a billion quantum Mars; a slew of possibilities from Barsoom at one end of the probability spread to tripod fighting machines and delicate crystal cities at the other. Humped along the bell-shaped curve in the middle, the likelier, possible Marses. Simple school algebra will give you the best likely solution. Output, and let that be your reality. Terraforming by quantum leap. Nudges along the path to inhabitability. More than terraforming. Whole-universe-forming. The quantum machines, the AIs that have, in the private mindspaces where humans cannot go, given themselves the names and natures of angels, have always understood that reality is a construct of language. They know what the shamans knew; that words, whether in primal chant or machine code, have power over the physical universe.
And somewhere in that polyverse, lies that answer that makes the theory real, and, by the gods whose power they have usurped, the machines are going to have a go at it. But what kind of Mars? Whose dreams will frame it? An old cosmonaut, left on the pad like a jilted bride, who casually asked a foolish prophetic question of a plastic box. A young construction worker, who is shown the glory every day and every night has it taken away from him, whose mind is sent spinning across space by quantum computers. These, certainly, and others besides, millions of others, brought to this place that is white with the light of millions of universes, to speak their dreams and tell their stories.
“Well, I could as well argue you’re my illusion,” Antti Selkokari said to the young Indian man standing before him barefoot in an incongruous paper coverall. “After all, I can understand you and you can understand me, And where does that happen except in dreams? And you’re hardly dressed for the cold. You’d be dead after ten minutes in that, where I come from.”
“And what about you?” Ashwin Mehta argued. “An old man with a compass? Very allegorical.”
“All right, then,” Antti said. “We’ll agree that each is a figment of the other’s imagination. So, then, who imagined all these?”
Figures were advancing through the white fog on all sides. Men, women, children, all ages and races and stations, walking patiently, silently. Between them, Antti and Ashwin saw other figures emerging from indeterminacy. Beyond them, yet others. The two lost men stood at the center of a great congregation of people.
“Who are you?” Antti demanded, more bold than Ashwin in the face of a faceless mass. “Where is this place? What do you want?”
A woman stepped forward. She was small, dressed in a simple shift frock, barefoot, her hair badly cut, urchin crop. She had soft black eyes and when she spoke, both men heard her in their own tongues, with an American accent. She said, “In answer to your questions: first; my folk don’t really do names—we’re AIs—but if you want to call me something, call me Catherine. It’s as good as any. Second: that entirely depends on you, all, but at the moment it might help to think of yourselves as individuals accidentally caught up in an experimental superimposed quantum state. Or a convocation, if that helps. Third: your stories. Your visions. Your hopes. Your Marses.”
Silence across the white plain. The shabby little woman turned to the great mass of people.
“Hey! It’s your world. You all have a say in it. Say nothing, and that bit goes unsaid. Your works build it, your stories tell it. Listen: quantum reality is information, pure and simple. Language defines what’s real: it’s the same for AIs as it is for humans. Deep down, everything is a story. We’re all tales. Tell me. Tell me your stories. We’ve got a world to build, and build it right.”
Against reason, Antti found words bubbling up in his throat. They were not demands for explanations that made sense, to be shown the way home. They were heart words, old memories and passions surging up like water from a deep aquifer struck by a well. It was a story of Mars, and the story of his own life.
He told of the night with the crisp of autumn first on the air when his father lit a bonfire on the beach and his children, following the sparks up into the night sky, had seen one that did not fly and fade. “That is no spark,” he remembered his father saying. “That is another world. Its name is Mars.” Another world! As complete and self-contained and full as this. A childhood of frequent illnesses was self-educated with old People’s Encyclopedias. Short on the rest of the world, but long on the wonders of astronomy. Sitting up late, late to listen to the beep on the radio that was Sputnik calling Earth. Again, that hot summer day when his father came running from the house to call him in from football to see the pictures of the capitalists walking on the Moon.
“That was when I decided I wanted to be a cosmonaut,” Antti said. “The Americans had put their flag on the Moon, but Mars, Red Mars; that was always ours.”
As he spoke, he became aware of the young man Ashwin’s voice, telling his own story: a strange and mighty one, of a world very alien to his own, and all the other voices on this featureless white plain, telling their tales and dreams of that little red light in the night.
Antti told them of the Air Force, when it had been a thing of pride and honor, and the passion and energy of young men who drive themselves toward a single ambition. The trials, the tests, the skills, the physical rigors and disciplines, the sacramental hours alone in the training jet, up on the lonely edge of the world, only the stars above him. The tensor mathematics would have finished him had he not found the humility to go home to his father, a schoolteacher, and ask his help.
“And cosmonaut training!”
It was only after that Kazakhstan morning, when ATOM 12 died, that Antti Selkokari realized his entire life and energy had been focused on that red dot in the sky, like a laser sight. As he told of the hours in the centrifuge, the constant medical testing—his childhood sickness a permanent dread—the team-building exercises, the Kamc
hatka survival course, the hours in the underwater tank, the hours and hours in the mock-ups and simulators, doing it over and over and over and over until they could do it blindfolded; the hours and hours and hours at the desks in front of the blackboards, working it out again and again and again. The crew interviews; how he thought his heart would stop when the letter came with the crest of the space agency, yet his fingers had no hesitation ripping it open. He still could not remember what it said beyond the key words. Glad. Successful. Mars. Novy Mir. Report.
He told about Milena. How overjoyed she had been, how proud! A cosmonaut’s wife! They celebrated with Cuban cigars and good vodka. A party member’s daughter could get the good stuff. She came at him fast and hot that night: there was a child to be conceived. A keep-safe, in case. Space was big. Radiation hard. Mars far and cold. Unflinching how it had all fallen apart, afterward. The failure had not been his, but it is a sin women do not forgive.
That morning, always coming back to that morning. The cold; clear Kazakhstan light; the jokes in the back of the truck that died one by one as they drew nearer to the great white rocket. The frosting he had noticed on the rippled white skin as they rode up the elevator, helmets under their arms. The cameraman crouching beside the gantry, their nonchalant waves. Hi, we’re going to Mars! Vorontsev, Nitin, Rozdevshensky, Selkokari. The startled birds flapping across the steppe. The hatch dogging, screwing the umbilical into the LSU. The startled grunt on the intercom as Mission Commander Rozdevshensky was told something they could not hear and he could not quite believe. The dogs turning. The ray of golden morning light. Barsamian’s hand reaching in: come now, quick now, get unfastened there and come with me. The ride down in the elevator. The ride no one had ever thought to take. The van bouncing over the rutted dirt road to the control bunker, and the word from Kirilenko that the thing was poisoned, had always been poisoned, was nothing but a tool in Politburo maneuvers.
