IN THESE PAGES YOU WILL FIND THE METICULOUS RECONSTRUCTION of a five-day scientific crisis that culminated in the near extinction of our species.

It is important to recognize up front that the advanced technology that is the hallmark of our modern world was not itself the cause of this crisis—though it exacerbated it. The response to the Andromeda Evolution was unprecedented in its coordination and scientific sophistication. Yet it was this same scientific mastery that enabled tragic errors resulting in terrible destruction and loss of life.

Nevertheless, it is vital this story be told—now more than ever.

A greater number of human beings walk the earth today than at any other point in the history of our species. We are able to survive in our billions thanks only to the technological infrastructure we have built to sustain ourselves. And every last one of us could be gone tomorrow, confronted with the failure of that same infrastructure.

My hope is that this rigorous account of events will demonstrate both the capabilities and the limits of scientific progress—the good and the bad.

An accurate and detailed reconstruction was only possible thanks to the generous contributions of those who were involved in the disaster, directly or indirectly, as well as a small army of domain experts and fact-checkers. I wish to thank them all, though I must take responsibility for any errors or omissions that have crept into this manuscript.

For their chapter-by-chapter technical corrections, my sincere gratitude goes to Captain Jake B. Wilcox, US Air Force (Ret.); Liu Wang, PhD, China National Space Administration (CSNA); Deepayan Khan, PhD, Carnegie Mellon Robotics Institute; David Baumann, Chicago Dynamics Incorporated; Ricardo Boas, Department for Isolated Indians, FUNAI; and Jane Hurst, PhD, NASA Johnson Space Center.

The bulk of this work depended on the efforts of Dr. Pamela Sanders, a US Army colonel, professor, and head of the Department of Electrical Engineering and Computer Science at the US Military Academy at West Point. With the help of her indefatigable students, Dr. Sanders was instrumental in securing, transcribing, and categorizing thousands of hours of video footage, audio recordings, and raw sensor data recovered from body-mounted cameras, the logs of the International Space Station, salvaged aerial drones, and satellite-based surveillance systems (in cooperation with the National Reconnaissance Office).

I especially wish to thank the surviving members of the second-generation Project Wildfire, who were able to sit with me after their debriefings to verify even the most minute details. And for those members who did not survive, I offer my heartfelt thanks to the friends, coworkers, and family members who set aside their grief to share the intimate stories necessary to convey their loved ones’ unique constellations of personality, expertise, and motivation. It is thanks to their gracious efforts if these pages are able to breathe life and humanity into what could otherwise be a dry and technical treatment of events.

By compiling a multitude of personal viewpoints along with hard facts, I have attempted to capture the fear and wonder that fueled the deadly events of these five days. In some cases, the reader must bear with practical reports based on little more than hard data, but when possible, this reportage has been bolstered with subjective opinions, thoughts, and emotions reported after the fact. By using both avenues of information, I have taken the liberty of reconstructing events to provide a more traditional narrative experience.

Lastly and most importantly, this account would never have been possible without the groundbreaking work of the late Michael Crichton, MD—a visionary who shattered a code of silence and introduced a stunned world to the precursor events to this crisis. The original account of the Andromeda Strain, published fifty years ago, opened the eyes of millions of readers to the great potential and dire limitations of scientific progress. Along with countless others, I am forever in awe of and deeply indebted to Crichton’s contributions.

It may seem disheartening that this new crisis unfolded along the same fault lines of human hubris, miscommunication, and plain bad luck as the first Andromeda incident. However, it is not my intent to vilify or blame any institution or individual. In the moment, each of us necessarily believes we are the hero of our own story—even those of us later judged to be villains.

I will leave such judgments to you, the reader.

The scientists, astronauts, and soldiers who lived through the events described in these chapters were human beings, with strengths and flaws. Some showed surprising heroism in the face of annihilation, while others failed at crucial moments. But none acted in vain—for at the very least, we all of us are still here, still alive to read and learn from this unlikely chronicle of human survival, a saga known now by its code name: the Andromeda Evolution.

WHEN IT ALL BEGAN AGAIN, PAULO ARAÑA WOULD have been bored. Bored and sleepy. He was only a year from retirement from the National Indian Foundation of Brazil, known under its Portuguese acronym FUNAI. Stationed on the outskirts of government-protected land stretching across the Amazon basin, the sertanista was in his mid-fifties and had spent his career protecting the undeveloped interior of Brazil. He was sitting under a flickering, generator-run lightbulb, lulled to drowsiness by the rising morning heat and the familiar sounds of the untamed jungle outside the open windows of his monitoring station.

Paulo was at least thirty pounds overweight, sweating in his official olive FUNAI uniform, and seated before an old metal desk loaded with an eclectic array of electronic equipment. As was his habit, he was squinting down at his lap, his concentration focused intently on hand-rolling a tobacco cigarette with his blunt yet surprisingly agile fingers.

His movements were sure and quick, with no hesitation or trembling, despite the gray whiskers jutting from his cheeks and his steadily failing eyesight.

As he lit and puffed contentedly on his cigarro, Paulo did not notice the red warning light flashing on his computer monitor.

It was a small oversight, normally harmless, and yet on this morning it carried consequences that had already begun to snowball exponentially. The unseen light was hidden behind the curl of a yellow sticky note (directions to a local fishing hole). It had been blinking unheeded since late afternoon the day before.

The flashing pixels were signaling the beginning of a global emergency.

A THOUSAND FEET overhead, an Israeli-made unmanned aerial vehicle (UAV) the size of a school bus was thrumming steadily over the vast Amazonian jungle. Dubbed the Abutre-rei—“King Vulture” in Portuguese—its wheels were caked in reddish jungle mud from a rough landing strip and its white hull streaked with the corpses of insects. Nevertheless, the drone was sleek and predatory—like an artifact from the distant future that had slipped backward in time to hover over this prehistoric land.

The Abutre-rei was on an endless mission, sweeping back and forth over a green sea of jungle canopy that stretched to all horizons. The unblinking black eye of its gyro-stabilized, self-cleaning camera lens was trained on the ground below, and a Seeker ultra-wideband synthetic-aperture radar unit invisibly illuminated the complex terrain with timed pulses of radio waves that could penetrate rain, dust, and mist. Back and forth, back and forth. The drone was specialized for environmental monitoring and photogrammetry—relentlessly constructing and reconstructing an ultra-high-resolution map of the Amazon basin.

Inside his monitoring station, Paulo only half watched as the constantly updating image knitted itself together on his monitor. An occasional haze of stale bluish smoke rose from the spit-soaked cigarro parked in its usual spot at the corner of his mouth.

Everything changed at precisely 14:08:24 UTC.

At that moment, a new vertical strip of mapped terrain was added to the composite image. The unseen warning light was displaced fifty pixels to the left, just peeking out from under the sticky note.

Stunned, Paulo Araña stared at the pulsing red spot.

In recovered webcam footage, he could be seen blinking frantically, trying to clear his eyes. Then he snatched away the sticky note and crumpled it in his fingers. The dot was located beside a small thumbnail image of something the Abutre-rei had found in the jungle. Something Paulo could not even begin to explain.

Paulo Araña’s job at FUNAI was to monitor and protect an exclusion zone established around the easternmost region of the Upper Amazon—over thirty-two thousand square miles of unbroken jungle. It was a priceless treasure, site of both the largest concentration of biodiversity on earth and a terra indigena that was home to approximately forty uncontacted Amazonian tribes—pockets of indigenous human civilization with little or no exposure to the technology and disease of the outside world.

With such natural riches, the land was under constant attack. Like an army of termites, destitute locals were motivated to sneak into protected territory to fish virgin rivers or poach valuable endangered species; loggers were tempted to bring down the huge kurana, cedar trees that could fetch thousands of dollars on the black market; and of course, the hordes of narcotraficantes stopping over on their way from southern Brazil to Central America were a constant and brutal menace.

Preserving the wilderness required unwavering attention.

With a nicotine-stained finger, Paulo pecked a key to activate Marvin, a computer program housed in a beige plastic box wedged under his desk. Acquired years ago from a joint research effort with an American graduate program, the battered box was unremarkable save for a faded printout of an old Simpsons cartoon character taped to the outside.

On the inside, however, Marvin housed a sophisticated neural network—an expert system that had been trained on thousands of square miles of real jungle imagery, and over a hundred million more simulated.

Marvin could reliably identify a quarter-mile airstrip hacked out of the remote jungle by drug couriers; or the logging roads that threaded like slug trails into the deep woods, with larger trees intentionally left unmolested as cover; or even the occasional maloca huts built by the uncontacted tribes—rare and intimate glimpses of another world.

Most importantly, the program could scan ten square miles of super-high-resolution terrain in seconds—a feat impossible for even the most dedicated human being.

Paulo knew that Marvin was muito inteligente, but it had outright rejected this new data as not classifiable. This was something the algorithm had never seen, not in all its petabytes of training data.

In fact, it was something nobody had ever seen.

The output simply read: CLASSIFICATION RESULTS: UNKNOWN.

Marvin hadn’t even offered a probability distribution.

Paulo didn’t like it. He made a kind of surprised grunt, the cigarette trembling on his lower lip. Tapping keys rapidly, he enlarged the thumbnail image and examined it from every available angle, trying to dismiss it as a glitch. But it was no use—the strange sight defied explanation.

Something black was rising from the deepest jungle. Something very big.

Paulo waved smoke away with one hand, his gut pressing against the cool metal desk. He squinted at the dim screen, pushing his face closer. His balding head was coated in a cold sweat, gleaming under the stark light of the bulb overhead.

“No,” Paulo was recorded as saying to himself. “Isto é impossível.”

Thumbing a switch on a battered 3-D printer, Paulo waited impatiently as the raw image data was transferred to the boxy machine. The shack soon filled with the warm wax smell of melting plastic as an array of pulsing lasers set to work. Inch by inch, a hardened layer of plastic rose from the flat bed of the printer. As the seconds ticked by, the formless sludge resolved into a three-dimensional topographic map.

The pale white plastic was rising up in the detailed shape of the jungle canopy, looking for all the world like a bed of cauliflower.

Rolling and lighting yet another cigarette by instinct, Paulo tried not to watch as a new world slowly emerged from the unformed ooze. Each layer hardened in seconds, quickly firming into a scale model of the jungle. Wheezing slightly, Paulo cracked his knuckles one by one, staring blankly and smoking in silence.

In the rare instance that Marvin returned less than an 80 percent classification probability, it was up to Paulo to make the final determination. He did so by employing a carefully honed method that was strictly unavailable to the machine: his sense of touch.

Touch is the most ancient sensory faculty of any living organism. The human body is almost entirely covered with tactile sensors. The neural circuits related to the somatosensory system overlap with multiple other areas of sensing, in ways both unknown and unstudied. Of particular sensitivity are the countless mechanoreceptors in our lips, tongue, feet, and, most especially, our fingertips.

This was Paulo’s talent—one area where man rose above machine.

Eyes half closed, he began with static contact, lightly placing all eight of his finger pads on the model surface. Gently, Paulo added steady pressure to establish a touch baseline. And finally he scanned his fingers laterally over the meticulously rendered folds of jungle canopy.

Properly honed, the discriminatory power of skin receptors can exceed visual acuity. Every inch of the model’s texture corresponded to roughly one hundred yards of real-world terrain, resulting in contours only detectable through a cutaneous spatial resolution far superior to any computer’s image analysis, no matter how clever the machine.

Paulo could run his fingertips over the roof of the jungle and feel whether an unclassified data sample was the ragged, chain-sawed destruction of an airstrip or the smooth banks of an innocent new river tributary.

Eyes closed, limp cigarette in the corner of his mouth, Paulo slouched, his face to the ceiling. His outstretched hands traced the surface of the jungle as if he were a blind god touching the face of the planet.

When his questing fingers found the hard, unnatural lines of the … thing, Paulo Araña swallowed a low moan in the back of his throat. Whatever it was, it really did exist. But there were no roads nearby. No sign of construction. It could not be possible—out there alone and colossal among the primordial trees—and yet it was as real as touching the stubble on his own face.

The thing in the jungle rose at least a hundred feet above a skirt of raw wilderness, long and slightly curved, like a barricade. It spoiled the sanctity of a rain forest otherwise unbroken for thousands of square miles. And it seemed to have appeared from nowhere.

Around the perimeter of the structure, Paulo could feel a crumbling sensation. It was the texture of death—thousands of virgin trees collapsed and sick. This thing was a kind of pestilence, polluting everything nearby.

For a long moment, Paulo sat and contemplated raising an alert on the antiquated FUNAI-issued shortwave radio sitting on his desk. His eyes lingered on its silver dials as the generator puttered outside, providing the trickle of electricity necessary to connect this isolated shack to the rest of the world.

Pushing away from the desk, Paulo felt blindly under the drawers until his fingers brushed against a business card taped beneath. It contained the phone number of a young American who had recently contacted Paulo.

Claiming to be a businessman, the man had explained that a Chinese aircraft had recently been lost over this territory. His company was willing to pay a hefty price for information about it. Paulo had assumed (and continued to assume) that the American was looking for pieces of airplane wreckage, although he hadn’t said that. Not exactly. Instead, the man had said specifically to report “anything strange.”

And this was definitely that.

Using his palms to wipe away the sheen of sweat that soaked his face like tears, Paulo stared at the business card and punched a number on his desk phone.

A man with an American accent answered on the first ring.

“I’m glad you called, Mr. Araña,” said the voice. “I was right to trust you.”

“You already know?” Paulo asked, glancing at the computer screen.

“Marvin rang me just now, when you registered the anomalous classification,” said the voice. “He’s smarter than he looks.”

The Americans and their trickery. It never ceased to amaze Paulo. A people who seemed so trusting and forthright—all smiles … and yet.

“What now?” asked Paulo.

“You can relax, Mr. Araña. We’ve got people taking care of it. You’ll be well compensated for your assistance. But I am curious,” asked the voice. “What do you think it is?”

“I know it is not an error, senhor. It’s really out there. I have touched it.”

“Well, then?”

Paulo thought for a moment before answering. “It is a plague. Killing everything it touches. But I can never know what it is.”

“And why is that?”

“Because that thing out there … it was not built by any human hands.”

Fairchild AFB

NEARLY FIVE THOUSAND MILES AWAY, NEAR TACOMA, Washington, Colonel Stacy Hopper was arriving to a quiet morning shift at Fairchild Air Force Base. A skeleton crew of intelligence analysts who had worked overnight were just clocking out, leaving behind dimmed monitors on neat desks and a meager work log indicating that, as usual, nothing much had happened.

Crisply uniformed in her air force blues, complete with a service cap, tie tab fastened neatly around her neck, and sensible black hosiery, Hopper eyed the windowless control room. A thermos of coffee rested in the crook of her arm. Her morning crew of eight uniformed intelligence analysts were settling into their consoles, saying their good mornings, and slipping on headsets. Many of them had damp shoulders, having just arrived to work on another rainy morning in the Pacific Northwest.

Hopper sat down at her own console at the back of the room, enjoying the soft murmuring of her analysts’ voices. Glancing up at the telemetry monitors lining the front wall, she saw nothing out of the ordinary—just the way she liked it.

It was said by her colleagues (in private) that Hopper, a calm, gray-eyed woman, had the patience of a land mine. In fact, she was perfectly satisfied with the slow pace of this job. She was the third acting commander of the project. Both of her predecessors had devoted the entirety of their careers to this post. As far as Hopper was concerned, it would be perfectly fine if Project Eternal Vigilance lived up to its name.

By the account of her longest-serving analysts, Hopper was fond of the rather pedantic saying “Absence of evidence is not evidence of absence.”

It was a sentiment that had begun to go stale among her staff.

This low morale was ironic, considering that at its inception, Project Eternal Vigilance had been considered the prime posting within all armed forces, and every roster spot vigorously competed for (by those with the security clearance to even know of it).

The project had been spawned in the aftermath of the Andromeda incident—a weapons research program gone horribly wrong, detailed in the publication popularly known as The Andromeda Strain.

In the late 1960s, the US Air Force deployed a series of high-altitude unmanned craft to search for weaponizable microparticles in the upper atmosphere. In February 1967, the Scoop VII platform proceeded to find exactly what the military men were looking for, except that the original Andromeda Strain was far more virulent than anyone could have guessed.

Before it could be retrieved by military personnel, the recovery capsule was compromised by overly curious civilians. The microparticle proceeded to infect and gruesomely wipe out the entire forty-eight-person population of the town of Piedmont, Arizona—save for an old man and a newborn baby. These surviving subjects were discovered and rescued by the acclaimed bacteriologist Dr. Jeremy Stone and the pathologist Dr. Charles Burton. The two survivors were isolated for study in an underground cleanroom laboratory, code-named Wildfire. Their fates were eventually classified to protect their privacy.

It was in Wildfire that a team of eminent scientists, hand selected for this situation, raced to study the exotic microparticle later dubbed AS-1; they found that it was one micron in size, transmitted by inhalation in the air, and caused death by near-instantaneous coagulation of the blood. And although its microscopic six-sided structure and lack of amino acids indicated it was nonbiological, AS-1 proved capable of self-replicating—and mutating.

Before the Wildfire team could finish their tests, the Andromeda Strain evolved into a novel plastiphage configuration called AS-2. Though harmless to human beings, AS-2 was able to depolymerize the plastic sealing gaskets that isolated the laboratory bulkheads. A nuclear fail-safe was triggered and heroically disarmed moments before detonation.

However, remnants of the AS-2 variety escaped, the particles outgassing into the atmosphere and dispersing globally. Although this new particle was not harmful to humans, it wreaked havoc on nascent international space programs that depended on advanced polymers to reach orbit.

Thus began Project Eternal Vigilance.

Hours after the Andromeda incident, the founding members of Project Wildfire lobbied the president of the United States for emergency resources. The goal was to begin worldwide monitoring for new outbreaks of the Andromeda Strain or its subsequent evolutions. Their proposal was given immediate and generous funding from the Department of Defense black budget, staffed with top analysts, and officially activated three days later.

But that was over fifty years before, and every scientist involved in the first Andromeda incident had since passed away.

Today, Colonel Hopper watched as the rows of computer monitors came on, bathing her analysts’ faces in bluish light. The colonel sighed at the view, ruminating on the huge expense necessary to secure every bit of satellite time, every analyst hour, and the immense amounts of data transfer and storage.

Colonel Hopper was well aware of her unit’s dwindling influence. At every morning shift, she noted the increasing mileage on her equipment, the attrition of her best analysts, and the encroaching needs of the other units at work in Fairchild AFB.

In particular, Air Mobility Command (AMC) had been pushing for more satellite time to ease their daily task of coordinating KC-135 Stratotanker aerial refueling craft in the thin air high above Tibet and the Middle East. The acting commander of AMC had even gone on record with the opinion that Eternal Vigilance was a pointless waste of resources.

And it seemed he was correct.

Eternal Vigilance had been on high alert for over fifty years—with Hopper at the helm for the last fifteen. And before today, it had never found a single thing.

IT IS A WELL-ESTABLISHED Achilles’ heel of human civilization that individuals are more motivated by immediate private reward than by long-term, collective future benefits. This effect is particularly evident when considering payoffs that will take longer than a generation to arrive—a phenomenon called intergenerational discounting.

The concept was formally introduced by the young French economist Florian Pavard during a poorly attended speech at the International Conference on Social Economics on October 23, 1982:

The average span of a human generation is twenty-five years. Any reward occurring beyond this generational horizon creates an imbalance that undermines long-term cooperation. In short, we as a species are motivated to betray our own descendants. In my view, the only possible solution is the institution of harsh and immediate punishments for those who would be unfaithful to the future.

It has been subsequently theorized that our species’ seeming inability to focus on long-term existential threats will inexorably lead to the destruction of our environment, overpopulation, and resource exhaustion. It is therefore not an uncommon belief among economists that this inborn deficit represents a sort of built-in timer for the self-destruction of human civilization.

Sadly, all the evidence of world history supports this theory.

And thus, despite well-known deadly high stakes, Project Eternal Vigilance suffered from endemic human shortsightedness. Over the years, the operational capacity of the program had been deferred, discounted, and diminished. And on this particular rainy morning, the project was on its last legs, barely functioning … but still viable.

At 16:24:32 UTC Colonel Hopper was seen on internal video, sitting at her desk with perfect posture. Her half-empty thermos of coffee rested atop a pile of equipment requisition forms that she must have known would be denied, and yet had forced herself to complete anyway.

A call came through.

Sliding on her headset, Hopper punched a button on her comm line, her monitors erupting into life.

“Vigilance One. Go ahead,” she said, speaking in the clipped tones of a lifelong data analyst.

The voice she heard had a distinct American accent, and she recognized it from her dwindling team of field operatives.

“This is Brasiliero. I’ve got something you’ll want to see.”

“Private channel is open, pending certificates.”

“Pushing through now.”

Tapping keys, Hopper granted the request.

All at once, the bank of four flat-panel monitors lining the front wall flared with data. Each monitor showed a discrete overhead view of the Amazon jungle: a basic unenhanced digital camera image; a light detection and ranging (LIDAR) map; an enhanced-color hyperspectral view of the canopy; and the minutely detailed gray-scale topography of synthetic aperture radar.

The drone footage was live, being generated in real time.

One by one, the eight analysts looked up at the front screens, pushing their chairs away from desks and murmuring to one another. Personalized workstations began to blink with ancillary data, information flowing to specialists according to their domain of control. Colonel Hopper stood.

In the dead center of every image stood something unexplainable.

It appeared to be a featureless block, curved slightly. It rose above the steaming expanse of jungle, laid directly across a river tributary. At its base, sluggish water flowed from underneath. Behind it, the blocked river had pooled into what looked like a giant mud puddle, flooding the surrounding jungle. The nearby trees and vegetation that hadn’t been swamped seemed frail and bent, dying.

“The anomaly is located on the descent trajectory of Heavenly Palace,” said Brasiliero, over the room speakers. “The Tiangong-1 space station was directly above—”

“Roger that, Brasiliero. That will be all for now,” replied Hopper, putting the connection on hold.

With a glance, Hopper checked the latitude and longitude. The anomaly was perfectly equatorial, with a line of zero degrees latitude to seven decimal points—a precision of approximately one yard. She added this observation to the incident notes. It was an odd detail, seemingly important, and yet catastrophically misleading.

Dale Sugarman, the senior signals intelligence analyst, stood up and turned to face Colonel Hopper, his headphones dangling around his neck. In five years, she had never seen the huge man demonstrate excitement about anything other than video games. Now, the senior airman’s shaky voice echoed sharply through the all-room speaker loop: “This data is impossible, ma’am. There are no roads, no airstrip, no way to build anything out there. Sensor error. I advise overhauling the drone. Send in—”

“‘Impossible’ is the wrong word, Airman,” said Hopper crisply, crossing her arms. A conviction crept into her voice as she continued, “What we are seeing is not impossible. It is simply an ultra-low-probability event.”

The room fell silent as the analysts considered her words.

There exists a certain class of event that can technically occur, yet is so incredibly unlikely that most laymen would consider it impossible. This false assumption is based on a rule of thumb called Borel’s fallacy: “Phenomena with extremely low probabilities effectively never happen in real life.”

Of course, the mathematician Émile Borel never said such a thing. Instead, he proposed a law of large numbers, demonstrating that given a universe of infinite size, every event with nonzero probability will eventually occur. Or put another way—with enough chances, anything that can happen will happen.

For the rare patient ones among us, the data-driven, those who are not afraid to delay gratification and save their dessert for last—these low-probability events aren’t inconceivable; they are inevitable.

Colonel Hopper was supremely patient, and as the world accelerated faster, she seemed to move more slowly. Indeed, she had been carefully selected by her predecessors for this particular ability.[fn1]

Fifteen years of toiling without reward or the promise of one, without encouragement, and often without even the respect of her colleagues—and Hopper had never once wavered in her commitment to the job.

And in this crucial moment, her persistence paid off in spectacular fashion.

COLONEL HOPPER FISHED out a thick binder from her top drawer and thumped it onto the desk. She was determined to make sure the rest of this encounter unfolded according to protocol. Using an old-fashioned letter opener, she tore through several seals to access the classified, laminated pages within. Although most emergency procedures were now automated, these instructions had been set down decades ago, and they called for a trained and capable human being to be in the loop every step of the way.

Pulling the headset mike closer to her lips, Hopper began issuing orders rapid-fire, with the certainty of an air-traffic controller.

“Brasiliero. Establish a thirty-mile circular quarantine zone with an epicenter at the anomaly. Pull that drone out of range immediately and land it at the perimeter. Once it’s down, don’t let anyone go near it.”

“Roger that, Vigilance One.”

Advanced computer models of the original Piedmont incident had indicated thirty miles as a minimum safe distance for airborne exposure. On screen, the real-time video shuddered and jerked as the Abutre-rei drone wheeled around and sped away in the other direction. After several seconds, the low-hanging nose camera had turned itself back one hundred and eighty degrees, and the anomaly reappeared on-screen, shrinking into the distance.

“Colonel, what does this thing have to do with us?” asked Sugarman in a quiet voice, his eyeglasses winking blue light from his workstation.

Hopper paused, then decided not to answer directly. Brasiliero’s earlier mention of the code name Heavenly Palace already represented a possible breach of classified information. Instead of responding, she moved to confirm the piece of information of most interest to Eternal Vigilance.

“Can you reconfirm that equatorial location?”

“It’s confirmed,” said Sugarman, hunching over his desk. “The anomaly is located on the exact equator, ma’am. Down to the centimeter, it looks like.”

Hopper took a deep, controlled breath. Aside from muted static, the room was utterly quiet. When Sugarman spoke, his voice was surprisingly loud.

“Why would an equatorial location matter?”

Hopper’s silence was jarring. The question could not be answered without compromising the security of the mission. It was information that could only travel up the chain of command, not down.

“Airman. Requisition the Transat Four satellite cluster, please. We need situational awareness on this, exquisite level.”

“Ma’am, that’s a collateral system. It’s being used by someone else. Currently logged for … CIA overseas usage—”

“You have my authorization to transmit Clear Eyes priority.”

Sugarman swallowed. “Yes, ma’am. We are seizing the satellite feed now.”

After a flurry of keypunches, an active satellite image blinked onto the front screens. It showed an infrared view of a jeep convoy speeding across dark desert terrain, leaving twin white tire tracks visible in the sand. Crisp black targeting crosshairs were overlaid on the image, above horizontal range lines.

From the in-room speakers, an unfamiliar and angry voice began to sputter, “Attention unidentified Clear Eyes permission. Get off this channel. You are currently interrupting a sensitive—”

“Rezone that eye to our coordinates,” said Hopper. “And mute that man.”

“Yes, ma’am.”

The room fell back into silence, except for the frantic typing of the analysts, each focusing their laser-like attention on a few drops of the rolling tide of data pouring into their monitors from the trunk feed.

Somewhere above, on a classified orbital trajectory, the lens of a spy satellite adjusted silently in the vacuum of space. The image of the jeep convoy blurred and disappeared from the monitors. Seconds later, the eye settled onto a patch of the Amazon jungle, and the camera iris spiraled into crystal clarity.

Across the monitors hanging high at the front of the room, the anomaly appeared in complex detail—its metallic-looking surface beaded with droplets of jungle mist, faint hexagonal imprints etched into its skin, and the whole of it gleaming like a beetle’s waxy shell in the rising midday sun.

“Infrared,” said Hopper.

On the second monitor, the image appeared in gray scale, with lighter pixels indicating hotter surface temperatures. The image of the surrounding jungle canopy dissolved into a grayish mass of what looked like storm clouds. The anomaly itself was pure white now, so bright it briefly washed out the rest of the image.

“It’s hot, ma’am. Really hot,” said an analyst. “See how the nearby vegetation is curling back?”

Hopper nodded, pointing at the monitor. “What are those faint speckles? All of them seem to be the same temperature, but cooling fast.”

At his desk, Sugarman put his face close to his dedicated feed. He spoke briefly into his headset to another analyst. Finally, he responded.

“We believe those are dead bodies, ma’am. About fourteen of them. Human.”

“You can’t possibly confirm that, Airman. Plenty of large primates live in that area of the world.”

“Some of them are carrying spears, ma’am.”

Hopper was silent for a moment.

“I see,” she said.

On screen, the thermal image flashed to white, saturating the sensor and washing out the screen. As the exposure slowly returned to normal, the anomaly seemed different. The fading specks were now closer to it.

“What was that?” asked Hopper.

“I … it appears to be growing,” responded Sugarman. “And there’s something new emerging from the middle of the lake. A smaller, six-sided structure.”

The third monitor lit up with splotches of color. A hazy cloud of blue and orange appeared in the atmosphere above the anomaly. It seemed to be drifting east on a slight wind current.

“We’ve got an ash cloud,” said another analyst. “The atmosphere down there is soaked with it. It must have been ejected from the anomaly somehow. More readings incoming …”

The colonel drew a finger down a column of figures on the top-secret laminated binder page. The vital information had been laid down as simply as a child’s book report, created with the age-old maxim of K.I.S.S.—“Keep it simple, stupid”—in mind.

Her finger stopped at a mass spectrum graph. There was a tremor in her voice as she issued her next command:

“Get the mass spec readings from the drone.”

“Already on it, ma’am.”

Seconds later, a junior analyst slid a mass spectrograph onto the colonel’s desk.

Once again, Hopper ran a finger across the laminated sheet. When she stopped and looked up, the tremor in her voice was gone.

“We have positive ID,” she said.

“Of what?” asked Sugarman, pivoting to face his boss. His lips were pale, voice dry and on the verge of cracking. Behind him, the entire room of analysts had turned to watch Hopper, solemn in their fear.

“The signature peaks are an almost exact match,” she replied, “to the Andromeda Strain recovered in Piedmont, Arizona, over fifty years ago. Somehow, something made of a similar substance is down in that jungle right now. And based on the visuals, it’s getting bigger. Those bodies are almost underneath it.”

“But that’s not—” Sugarman stopped himself. “You mean to say …”

Every person in the room knew the purpose of this mission. Yet none of them had ever actually believed the strain would reappear. Not even now, in the face of overwhelming evidence. Except for one.

Hopper stood and addressed her incredulous staff, tucking the binder under her arm.

“Project Eternal Vigilance has just fulfilled her purpose. Our work here is done. I wish you well on your future assignments, whatever they may be.”

Colonel Hopper then turned and walked directly toward the high-priority communications room—a soundproofed closet, really. The analysts watched her go with their mouths open, speechless.

Over her shoulder, Hopper issued her final orders.

“Alert your colleagues at Peterson AFB and transfer those feeds. Based on an exponential rate of growth, tell them I estimate we’ve got less than four days.”

“Four days? Until what?” asked Sugarman.

“Until that anomaly spreads all the way to the ocean.”

And with that, Project Eternal Vigilance was complete.

Alert

RAND L. STERN WAS ALREADY DEAD TIRED, AND THE day had hardly begun. A four-star general with a sprawling family and a rocket-powered career, Stern faced a constant and overwhelming demand for his attention. For his own part, he was simply looking forward to eating lunch for fifteen uninterrupted minutes.

Stern was a compact African American man in his fifties and only now going gray at the temples. A top graduate of the US Air Force Academy, he had spent thousands of hours as a command pilot in an F-16 Fighting Falcon, hundreds of those in combat. Afterward, he had done a stint as a professor at West Point. And for the last three years, he had been in charge of the United States Northern Command (USNORTHCOM) and the North American Aerospace Defense Command (NORAD), after his nomination was confirmed unanimously by the US Senate in 2016.

Stationed at Peterson Air Force Base in central Colorado, General Stern oversaw the activities of thirty-eight thousand individuals concerned with monitoring and protecting American interests in the area from two hundred to twenty-two thousand miles up, a volume of space dwarfing that of the entire planet. His annual budget was in the tens of billions, twice that of any existing multinational company.

If asked, he would respond that his most complex command assignment was the parenting of four preteen girls alongside his wife, a research scientist in the Department of Psychology at the University of Denver.

At home, Stern’s voice was only one among many. At work, however, he spoke for over three hundred million American citizens.

In his first-day briefing packet, Stern had been informed of twelve high-priority ongoing top-secret projects of extreme significance to national defense. Among them was something called Project Wildfire, created in the aftermath of the Andromeda incident of some fifty years before. Wildfire had seemed like an innocuous footnote compared to the ambitions of the Chinese and the astonishing amount of unaccounted-for nuclear material that had been lost in orbit. Yet during his tenure, no other project had been a bigger thorn in his side.

Dealing with the Andromeda microparticle had gone from a purely scientific undertaking to a secret arms race with the sort of global repercussions not encountered since the height of the Cold War. As a result, Project Wildfire had grown to consume a disproportionate amount of resources. It had become a gargantuan feat just to hide its dozens of subprojects from the public view, costing billions of dollars and millions of man-hours.

All of it weighed heavily on the general.

In a later interview, he described the job as “feeling like Atlas, crouched there alone, holding the planet in my arms—and nobody knows what I’m protecting them from or why. Not even my girls.”

Among the classified downstream projects, the existence of Eternal Vigilance was peripheral at best. Serious fear of another spontaneous mutation from the Andromeda microparticle had evaporated over time. Instead, what was most important were the possibilities of intentional weaponization by enemies of the state.

In typical human fashion, attention had turned away from the wondrous contemplation of extraterrestrials and settled squarely and mundanely on the countries (allies and not) who had inevitably learned about the deadly version of the microparticle called AS-1, and its plastic-eating cousin, AS-2.

Both varieties had proven to be dangerous in their own ways.

Upon inhalation, AS-1 was almost always immediately fatal. The relatively benign AS-2 variety, which had evolved spontaneously in the heart of the Wildfire laboratory, had shown itself capable of lingering in the upper atmosphere, turning most plastics into dust—a development that had set back the US space program by decades. It also made AS-2 samples freely available to any nation with the scientific acumen to go up and collect them.

No other varieties of Andromeda, natural or manufactured, had been detected—though not for lack of trying.

And now, the call Stern had been dreading for years had come from an utterly unexpected direction—not from his agents scrutinizing the China National Space Administration, or the spies sent to investigate disease outbreaks around the world, or even from a certain secret clean room still buried under a cornfield in Nevada.

The call had come from Eternal Vigilance.

Ensconced in his private office at Peterson Air Force Base, Stern had at first reacted to the emergency notification from Colonel Hopper with mild annoyance. Although false positives would normally be eliminated before reaching him, his assumption was that one had slipped through.

Dismissing an incongruous screensaver of kittens shooting rainbows from their mouths (a gift from his youngest daughter), the general accepted Hopper’s information push. As his screen flooded with images of the anomaly, he leaned back in his chair with fingers knotted over his stomach and closed his eyes in frustration.

“Colonel Hopper. What is this?” he asked.

“I have a theory.”

“You have a theory. I’m late for my lunch. Since the promotion, they’ve got my days regimented into ten-minute increments. There are only so many of these increments in one day. You are occupying one now. I would rather it be occupied by a bacon, lettuce, and tomato sandwich.”

“Yes, sir. Did you see the trajectory?”

“I see a static object in the jungle, Colonel. There is no trajectory.”

“On April tenth of this year, the Tiangong-1 Chinese space station fell into destructive reentry and disintegrated. That anomaly is perfectly equatorial, and directly in the debris trajectory of the fallen station. You may recall the incident was code-named Heavenly Palace.”

General Stern sat up abruptly.

“We can’t confirm what the Chinese were experimenting with on that space station,” Hopper added.

“But we have a pretty good guess, don’t we?” responded Stern, the data on his screen.

This problem had just moved into a sphere of his thinking that outranked meals. It was an area that concerned not only national defense but the defense of the species.

The general’s mouth moved as if to speak, and then it closed.

“Good work, Colonel. We’ll take on your feeds and any information you’ve collected. I’m … why, I can’t believe I’m saying this …

“I am now issuing a Wildfire Alert.”

IT IS A little-known fact that human logistics experts have not independently planned or executed a major military endeavor for the United States of America since early in the Vietnam War. Every operation, from single-element transports to coordination of an entire operating theater, is at least partially computer generated under the umbrella of a sprawling and complex collection of algorithms known as automated logistics and decision analysis (ALDA).

In this aspect, the Andromeda response was no different than any other complex military response—it was machine generated.

Given General Stern’s initial data, ALDA activated the Percheron supercomputing cluster located in the chilled depths of the Air Force Research Laboratories beneath Wright-Patterson AFB in western Ohio. Kicking or delaying thousands of other lower-priority computing threads, ALDA connected to a massive, constantly refreshed data set of personnel and resources, coming back with a full mission loadout within fifteen minutes.

Yet even with its unprecedented level of processing power and data, ALDA had always been wisely deployed with an 80/20 rule—which holds that an algorithm should be depended upon to reach only 80 percent of the solution, with human common sense and intuition applied to the final 20 percent.

In this case, General Stern saw no technical flaws with the default loadout, which read as follows (still in partial machine code):

Stern paused at the inclusion of Major Peng Wu, a Chinese national who normally would have been excluded as a security concern. Then he shook his head, cracking a wry smile. The ALDA algorithm was relentlessly logical yet had often proven itself capable of nonintuitive decision-making. Given the situation with Heavenly Palace, it was a stroke of genius to bring in a Chinese military candidate who had been waiting, preapproved, in the Wildfire candidate pool.

Peng Wu was not just any taikonaut—she had actually participated in the first manned voyage to the Tiangong-1 space station. Stern knew she wouldn’t divulge any Chinese military secrets—they’d already tried discerning that—but her knowledge of what had happened up there could still save lives.

At this point, General Stern’s only duty was to give a verbal confirmation. However, a final exchange took place in the seconds before the go order was passed on—both upward to the president of the United States and down to the enlisted men and women immediately dispatched to execute first steps.

The following is a partial transcript of the last-minute exchange between General Stern and one of his most trusted officers:

< … >

0–10 GEN

Strike the last field candidate. I have a replacement.

S-OP-001

Zack Gordon? Are you sure, General?

0–10 GEN

Send Stone.

S-OP-001

I’m sorry, sir?

0–10 GEN

James Stone. Out of Palo Alto. You’ll find him on the standby list.

S-OP-001

[short pause] Sir, do you mean the son of Dr. Jeremy Stone? From the first Andromeda incident? This guy hasn’t got the clearance. His prep work is also out of date. I believe he was always a tangential candidate, too special-purpose.

0–10 GEN

I know. Send him anyway.

S-OP-001

There will be a delay while we wait for his security clearance.

0–10 GEN

Understood. Scramble my personal C-40 transport and go get him. That’ll help mitigate the delay.

S-OP-001

[long pause] You were close friends with Dr. Jeremy Stone, weren’t you?

0–10 GEN

Your point?

S-OP-001

I’m just afraid … you should consider the optics on this.

0–10 GEN

Listen, son. It’s not your career on the line. I’m invoking directive 7–12, citing top-secret situational knowledge that must remain opaque. My voice is my clearance, and I am General Rand L. Stern.

S-OP-001

Acknowledged, sir. Dossier approved and … the mission is live.

[typing sounds]

S-OP-001

Enlisted liaisons are being dispatched now to retrieve our field team. You are advised to report to local command and control to assume overwatch duties. Good luck, sir.

Sir?

[brief pause]

S-OP-001

Sir. If you don’t mind my asking. Off the record …

Nothing is off the record. You know that.

S-OP-001

Well then, on the record, but between us.

0–10 GEN

All right. Shoot.

S-OP-001

Why James Stone?

[long pause]

0–10 GEN

It’s just a hunch. Nothing more.

Conservative estimates from the DC-based Nova America think tank conclude that Stern’s hunch likely saved three to four billion lives.

Emergency Debris Avoidance Maneuver

TWO HUNDRED AND FORTY-EIGHT MILES ABOVE EARTH, Dr. Sophie Kline floated quietly in a nimbus of her own long blond hair. It was just after 6:00 a.m. Greenwich Mean Time—the official time zone of the International Space Station, as a compromise to accommodate Mission Control in both Houston and Moscow—but her blue-gray eyes were wide open and alert. This early, both of her fellow astronauts were still in sleep cycle, and the observation cupola was shuttered, empty, and dark—the only sound a faint whirring from the Tranquility module ventilation systems.

It was Kline’s favorite time of day.

She punched a glowing button, and the hull began to whine as the exterior cupola shutters rose. The gentle glow of Earth’s surface lit the interior of the module, and Kline enjoyed the usual thrill in her stomach. She loved the feeling of being alone and suspended, looking down on the planet from on high. It gave her a sense of utter superiority, as if everything below were a part of her own creation.

This small daily ritual (confessed in a personal flight journal salvaged after the incident) might seem arrogant, but it was simply a dream of freedom.

As it was, Kline was floating in the windowed cupola with her paralyzed legs bound tightly together with Velcro straps to keep them out of the way. It was only in these quiet moments of weightlessness that she could almost forget the searing cramps and spasms that writhed through her devastated muscles.

Sophie Kline had not been able to walk since she was six years old, so she had chosen to fly. She was tall, despite her disability, and as she focused on the cupola window, her striking eyebrows and gaunt cheeks lent her a predatory appearance, softened only by a smattering of freckles across her nose and forehead.

Her path to the stars was so unlikely as to almost satisfy Borel’s fallacy. When Kline fell and broke her right arm at the age of four, her parents assumed she was simply clumsy or unlucky. Only one was true. At the hospital, an attentive pediatrician noticed that the little girl had a concerning tremor.

The incredibly unlikely juvenile amyotrophic lateral sclerosis (JALS) diagnosis came at the age of five, with the degenerative disease attacking her relatively newfound ability to walk. Sophie began her life in a wheelchair, though she had no intention of ending it there. With an almost inhuman resolve, particularly for a child, she had set her ingenious mind and iron will to escaping the bounds of gravity.

She had succeeded.

Every reputable doctor had predicted she would be dead by the age of twelve. Instead, she had persevered, taking advantage of each new medical advance, and eventually become a world-renowned scientist and an American astronaut.

Kline found that the chronic pain in her muscles nearly disappeared in microgravity, and her wasted body wasn’t a disadvantage the way it was on earth. In constant free fall, she was as physically capable as any astronaut. More capable, in fact, since she did not have to worry about the muscle-wasting effects of weightlessness.

Thus, using only her arms, Kline turned her body to face the circular porthole in the center of the viewing cupola. Six trapezoidal panes of glass splayed radially out from it—the largest window ever put to use in outer space. Beyond, the face of the planet slid past, surprisingly close. Today, she saw an endless jungle vista—a dense landscape of treetops twined with gleaming rivers that looked to Sophie like the wriggling trace of neurons.

It was a view that absolutely should not have been there, and the sight of it indicated that a serious emergency had occurred during sleep cycle.

Internal ISS video footage showed Sophie Kline muttering in disbelief, frantically scanning the computer monitors ringing the neck of the cupola. Physiological monitoring logs reported her heart rate elevating as she took hold of two slender blue handrails and pulled her face to within inches of the central porthole. The terrain scrolling past below would have been utterly unfamiliar to the seasoned astronaut.

Like the other two crew members on board the ISS, Kline’s body was instrumented with wireless physiological sensors. Unlike her crewmates’, however, Kline’s monitoring extended further—at one-second intervals, her mind was being read. As a teenager, Kline had been implanted with a Kinetics-V brain-computer interface (BCI) at her own insistence, so she could continue her college courses via computer as the disease progressed through her nervous system.

The BCI device was a golden mesh of thousands of wires, soaked in a biocompatible coating to prevent foreign body rejection, and sunk into the jelly-like surface of Kline’s motor cortex. Upgradable via radio, the current software iteration employed a deep-learning algorithm to map the electrical activity of neurons in Sophie’s brain to actions in the real world. The unique interface linked Kline mentally to the ISS computer systems—an almost telepathic connection.

Kline realized that the ISS had undergone a severe trajectory change. Such an event could only signal imminent disaster, and it should have been a cause for panic. Indeed, her outward reaction to the unexpected terrain had been consistent with surprise and shock. However, routine monitoring of her brain implant’s data stream showed that Kline’s predominant state of mind was an alpha brain wave varying between 7 and 13 Hz—a state of nonarousal, relaxed alertness in the face of mortal danger.

It was a small discrepancy that would go unnoticed until much later.

Kline opened a comm channel to Houston flight control and requested information from CAPCOM.

The initial response was static.

A lot had happened during the astronauts’ sleep period, beginning at precisely 23:35:10 UTC when, under the auspices of General Rand L. Stern, the USSTRATCOM Command Center issued an emergency notification to ISS Mission Control in Houston.

USSTRATCOM advised of a likely close approach of the ISS to multiple red threshold objects. Such notifications were fairly common, as the command center is tasked with monitoring any object in low orbit with a diameter larger than one and a half inches.

Officially, the debris source was attributed to a failed NSA satellite deployment, but console operators at Houston were backchannel notified that the orbital debris was in actuality the aftermath of a classified antisatellite weapons (ASAT) attack performed against China by Russia.

In public, these space warfare operations were universally condemned for scattering dangerous space junk in low Earth orbit. Yet it was an open secret that since the 1960s every spacefaring nation had been enthusiastically experimenting with ASAT platforms—from simple kinetic kill warheads to more sophisticated reusable approaches deploying shaped-charge explosives.

The attitude determination and control (ADCO) officer, at Mission Control, Vandi Chawla ran a simulation on the USSTRATCOM-supplied data and confirmed the high likelihood of a conjunction in the orbital pathway. Because they were red threshold objects, not yellow, there was no debate about the primary response. She immediately authorized an emergency debris avoidance maneuver (EDAM), even though the orbital modification would result in several missed launch opportunities over the next months, none of them critical resupplies.

While the astronauts slept, commands for a prolonged thirty-nine-minute avoidance maneuver were issued from the trajectory operations manager (TOPO) console. The ISS’s four 220-pound control moment gyroscopes shifted rhythm immediately. Made of stainless steel, the circular flywheels generated the torque that leaned the ISS forward at a constant four degrees—keeping the station’s floor pointed at Earth’s surface and maintaining an Earth-centered, Earth-fixed (ECEF) diving orbit. The electrically powered gyros began to modify the station attitude in preparation for the maneuver.

Once situated, the next step would normally have called for an extended thruster burn from the robotic Progress cargo module attached to the Pirs docking compartment. However, due to the substantial translation needed, TOPO decided to authorize use of an experimental solar electric propulsion (SEP) device.

Electrical power gathered by onboard solar arrays was routed to a cluster of highly efficient electrostatic Hall thrusters, conserving precious supplies of traditional chemical propellant. On activation, the thrusters pulsed in perfect rhythm, ejecting a flickering plume of plasma exhaust. The resulting force pushed the ISS upward directly through its center of gravity, while also translating the bulky structure to a southward trajectory.

A typical reboost maneuver would change only the altitude of the ISS, but in this case the azimuth was also modified from fifty-four degrees to zero, resulting in a highly unusual equatorial orbit. The maneuver was completed within the allotted time, and a summary press release was issued, citing a routine debris avoidance maneuver and praising the success of the SEP device.

General Stern had managed to coordinate the entire effort without ever informing NASA, RNCA, or JAXA of the true underlying emergency.

And yet Sophie Kline knew right away the trajectory change had something to do with Andromeda. This was not surprising, since Kline was one of the very few people intimately aware of the true purpose of the International Space Station.

The full, unclassified transcript of her initial exchange is below:

ISS-KLINE

Houston this is Station, come in. Requesting status update. What … [unintelligible] Why am I seeing Brazil moving east west?

HOU-CAPCOM

Just, uh, had an EDAM, Station. Orbital debris. Good news, though. The SEP thrusters worked perfectly.

ISS-KLINE

That is good news. But, this is so far … listen, I’m initiating a special query request. Have you been contacted by Peterson Air Force Base?

[static—four seconds]

HOU-CAPCOM

I’m sorry, Station, we’ve got no record—

[transmission lost]

[static—eleven seconds]

PAFB-STERN

Kline. This is Stern. We are on a private channel. I’ve got an update for your to-do list.

ISS-KLINE

Go ahead.

PAFB-STERN

Your scientific mission is suspended as of now. Until further notice, knowledge of your reassignment is to be restricted from all space agencies, including NASA. Do you understand?

[short pause]

ISS-KLINE

Yes sir, General Stern.

PAFB-STERN

You’ve been placed in an equatorial orbit that passes over the debris field of the fallen Tiangong-1 space station. We … It, it’s been hypothesized the station may have triggered a ground contamination upon reentry.

ISS-KLINE

In the jungle?

PAFB-STERN

Something is down there. Some kind of anomaly. It’s already killed people, and it’s spreading.

ISS-KLINE

I see.

PAFB-STERN

Project Wildfire has been reactivated, Dr. Kline. Your role is orbital lab support. The other ISS crew members will monitor for any remnants of the Tiangong-1 that are still atmospheric, under the guise of an emergency scientific mission.

ISS-KLINE

Understood.

PAFB-STERN

You will also monitor our field team from above. Eyes and ears. Got it?

ISS-KLINE

A field team? You’re not sending people into that jungle? General, please, at least wait until I can—

PAFB-STERN

No time, Doctor. Report to the Wildfire Mark IV laboratory module. It’s already begun.

THE EXISTENCE OF the executive order can seem contradictory to democratic government. In times of emergency or in peace, the president of the United States may simply dictate national policy and have it executed in an instant—without review.

This act has been previously described as: “Stroke of the pen, law of the land.”

The first executive order was used by George Washington on June 8, 1789, to instruct the heads of all federal departments to create a State of the Union for the newborn country. In 1863, Abraham Lincoln issued one that became known as the Emancipation Proclamation—ultimately freeing three million slaves. And nearly a century later, Franklin Delano Roosevelt issued a 550-word executive order that called for the United States government to incarcerate over a hundred and twenty thousand of its own citizens and residents of Japanese descent in concentration camps constructed across the Western United States.

It is a great and terrible power to wield, and one that can lead to historic repercussions—if it is ever made public, that is.

The classified executive order NSAM 362-S (known as a “National Security Action Memorandum” at the time) was issued three weeks after the first Andromeda incident and the subsequent back-to-back losses of the American Andros V manned spacecraft and the Russian Zond 19 mission. Within government circles, the order was widely regarded as symbolic. Off the record, many politicians considered the task to be on par with the Pharaohs’ orders to erect the great pyramids of Giza.

A portion of the order read:

TOP SECRET/FORMERLY RESTRICTED DATA ATTACHMENT NATIONAL SECURITY ACTION MEMORANDUM NO. 362-S

April 10, 1967

THE PRESIDENT
Ordering the Creation of a Microgravity Laboratory Module to be Placed in a Space Station in Permanent Orbit.

By the authority vested in me as President by the Constitution and the laws of the United States of America, I hereby determine that it is vital for national security and the safety of our species itself to study the extra-terrestrial microparticle known as the Andromeda Strain in its natural microgravity environment, i.e., a state-of-the-art laboratory placed in low Earth orbit.

The estimated cost of the endeavor in 1967 was $50 billion, twice the cost of the Apollo program and (adjusting for inflation) approximately the same as the entire national military budget of 2018. In the upper echelons of government executives who were authorized to read the order, the president’s demand was met with derision and disbelief.

But the practical need to study the particle remained.

By the fall of 1967, the tiny town of Piedmont, Arizona, had been sterilized from top to bottom and the forty-eight bodies (including two US Army personnel) cremated. Every structure and vehicle was deconstructed and placed in hangar-like storage facilities built in the desert by the Army Corp of Engineers for this purpose. The task was accomplished carefully and with no casualties, thanks to the findings of the Wildfire team. The effect was so sudden, and the town so small, that within two decades the very existence of Piedmont was erroneously thought by many to have been fictional.

Once every splinter had been accounted for, the next step was to determine exactly what had happened. It was a multibillion-dollar question, and the world couldn’t know it was being asked without risking a civilization-ending panic.

As the Indian-born British historian Romila Chandra states in her classic tome, Fallen Empires of Man, “The instinct of the human being upon contact with a foreign civilization is to flee. If that is not possible, it is invariably to attack. Only after surviving first contact is there an overwhelming urge to learn more. But do not mistake this response for altruistic curiosity, rather it is simply a need to understand the other in order to protect oneself from it … or, more likely, to attempt to destroy it.” It is an apt description of how humanity behaved in the aftermath of Andromeda—especially after Russia and China learned of and responded to the events in Piedmont, Arizona, through their own spycraft.

The Russians were first, managing to push the Salyut 1 space station into orbit by 1971—only four years after the Andromeda incident. The United States attempted to catch up two years after that, but the Skylab launch was compromised by the “benign” plastic-eating strain of Andromeda still lingering in the upper atmosphere. During Skylab’s initial ascent, exposure to the AS-2 plastiphage resulted in a partially disintegrated heat shield, spewing debris that severely damaged the station.[fn1]

Skylab lasted six years. The Mir space station lasted longer, at ten years. Both failed to achieve their secret goal of studying Andromeda in microgravity. As it turned out, the problem was too big for one nation to solve alone—even a superpower.

In 1987, President Reagan called for the creation of an International Space Station, a joint venture between the Soviet Union and the United States, with more partner countries to come. Eyebrows went up around the world, as the Russians and Americans made for strange bedfellows. Privately, both nations were motivated by a mutual fear of allowing the Andromeda particle to go unstudied.[fn2]

Even then, a permanent space station was only the first step.

It was not until 2013 that the Wildfire Mark IV laboratory module arrived (disguised as a Cygnus automated cargo spacecraft), and docked to the nadir port of the Harmony node at the front of the station. Its activation coincided with the beginning of Dr. Sophie Kline’s scientific missions to the ISS.

The top-secret module was born in the depths of the original Project Wildfire facility beneath Nevada, constructed entirely by sterilized robotic arms. Those robots were teleoperated by on-site workers who were themselves in an ISO Class 1 clean room. The final laboratory enclosure was completely self-contained and launched aboard an Antares-5 rocket from Cape Canaveral Air Force Station on January 17, 2013.

Once docked, the laboratory module constituted the only biosafety level (BSL) 5 containment facility ever created, much less placed in orbit. The Wildfire microgravity laboratory was self-irradiated every four hours with high-intensity ultraviolet light, and it contained no breathable atmosphere. It was instead pressurized with a combination of noble gases—odorless, colorless, and with virtually zero chemical reactivity. The cylindrical space inside the laboratory module was phenomenally clean and sterile, precisely because it was unoccupied.

There were only two potential organisms on board, and they were what the module had been built to study: material samples of the extraterrestrial microparticles known as AS-1 and AS-2.

The interior of the module had never been touched by a human being, and never would be. Every aspect of the laboratory’s functioning was remote-controlled via radio contact from outside. And this was exactly why Dr. Sophie Kline had been the first astronaut with ALS deployed to the International Space Station.

The wasting effects of Kline’s disease had made her the perfect recipient of a brain-computer interface at a young age. Years of training with the interface had given her the ability to control most computers as naturally as breathing—a crucial ability while handling highly dangerous samples through a remote connection.

Though there had been other operators, only Sophie Kline could control the Wildfire Mark IV laboratory module with her mind.

WITH GENERAL STERN’S orders to report to the laboratory module still ringing in her ears, Kline hesitated for one moment. Her left eye twitched almost imperceptibly as she activated the muscle groups necessary to communicate with her personal computer, which activated a monitor along the lower wall of the cupola.

A real-time camera feed of the Kibo science module appeared. There astronaut Jin Hamanaka, apparently also alarmed by the change in trajectory, was busily checking propellant levels on her laptop. On a feed of the Zvezda service module, the cosmonaut Yury Komarov was outside his sleep station, calmly stowing his gear and preparing for an exercise routine during the hour window before morning conference.

Kline watched both feeds carefully. As far as she could tell, the other astronauts were not panicking or behaving erratically.

Pushing herself backward, Kline floated away from the cupola and “up” toward the exit in the ceiling. As she floated away, she watched the sprawling rain forest hundreds of miles below. The vista was already rotating away, replaced by the Atlantic Ocean as the station continued its eastward orbit.

In another time, the young Sophie Kline would have been abandoned to a sanitarium, immobile and forgotten—assuming she survived her childhood. The sole reason she had transcended gravity was humankind’s ever-growing mastery over nature. Looking down on the planet from the perspective of a god, trapped in a body that refused to obey her orders, she was acutely aware of this fact.

But—as history has proven time and again—in the hands of human beings, increasing power is increasingly dangerous.

Heavenly Palace

THE COALITION OF COUNTRIES THAT FUNDED THE International Space Station (and hoped to share in its discoveries) had neglected to include one of the largest and most ancient civilizations in the world—a proud and capable nation with the strength to develop its own competing effort to study Andromeda.

Alone and forced to act unilaterally, the People’s Republic of China inevitably set out to do just that.

Suspicion, distrust, and competitiveness had fractured the international effort to understand the Andromeda Strain. Although the AS-1 microparticle had proven that it would kill any human with equal savagery, no matter their ethnicity, the vagaries of politics blunted what could have been a united response. And that enmity came to a head with the creation of a new space station.

The Tiangong-1, whose name meant “heavenly palace” in Chinese, was launched on September 29, 2011. It was an auspicious date for both travel and grand openings, according to the astrological predictions of the Chinese zodiac calendar, the Sheng Xiao. After a successful launch, the station was placed into orbit at a slightly inclined attitude of nineteen degrees—a trajectory that coincided perfectly with regular resupply launches from the Chinese Xichang Satellite Launch Center in Hainan Province.

Although the launch had not been advertised, American spy agencies watched intently and continued to monitor the station until its premature demise.

The end occurred in 2013, only two years into the multibillion-yen effort, when China suddenly announced that the project was over. Authorities there officially hailed Tiangong-1 as an “unmitigated success for the China National Space Administration and the Chinese people.”

However, around-the-clock observation from a series of earth-based imaging assets revealed a narrative very different than that of the official reports. It seemed Chinese Mission Control had lost radio contact, including telemetry, with their station.

Without any means of control, the Tiangong-1 fell into a decaying orbit.

Thermal readings from multiple spy agencies determined that life support had been shut off, with the surface of the station as cold as the space around it. Abandoned, the station continued to orbit the earth for several years, engines offline and radios silent.

On April 10, 2018, the scant air particles percolating in the upper atmosphere finally managed to drag the station into destructive reentry. The metal cylinder was ripped to superheated shreds by atmospheric friction, reduced to a flaming confetti that rained down on the planet below—directly above the primordial jungles of the eastern Amazon.

Thus, the entire effort ended in a brief streak of light and heat.

The failure would likely have been deemed harmless were it not for a single, final bit of information. During the continuous monitoring of the space station—from launch, to resupply missions, to its last fiery reentry—operatives had noticed something the Chinese space agency never mentioned publicly.

The last crew of three taikonauts had never emerged from the Tiangong-1.

Code Name Andromeda

BARELY FIVE HUNDRED FEET ABOVE A JUNGLE CANOPY that itself soared a hundred and fifty feet high in places, a Sikorsky H-92 Superhawk helicopter thundered over shivering trees. The gray metal chopper was streaked with jungle mist, nose jutting out like the beak of a predatory bird. In its wake, bands of monkeys hooted in the treetops and colorful birds took startled flight.

James Stone didn’t remember falling asleep.

Even with the thudding of the rotors in his ears and the vibration of the window glass on the rolled-up jacket he was using for a pillow, he’d had no trouble nodding off.

Later, when every detail of his life was declassified and dissected, splashed across the front pages of newspapers and magazines, it became well documented that Stone had the ability to fall asleep anywhere, at almost any time—to “turn off,” to use the parlance of soldiers.

James had been able to do this since he was a little boy.

Part of it must have been out of sheer necessity. Young James spent his childhood accompanying his famous father—the Nobel Prize–winning polymath Dr. Jeremy Stone—on his scholarly travels around the world. Well dressed and soft-spoken, little James seemed nothing like his loud, impatient father. Together they were an odd couple, circumnavigating the globe every few months as Dr. Stone delivered lectures, attended scientific talks, and toured various international scientific projects.

James very rarely saw his mother, Allison, after his parents were divorced near his ninth birthday. And although the two were so obviously different from one another, Stone’s father was clearly dedicated to ensuring that the boy learn something new every day of their never-ending travels. Today, this type of roving education is called world schooling.

Yet according to private interviews that were not splashed across the tabloids, there was another reason that Stone had become very good at falling asleep—it was because he so frequently woke up in terror, his skin crawling with the cobweb remnants of a singular nightmare. This time, aboard the Sikorsky, would have been no different.

In recovered cabin security footage, Stone woke with a start and stared dazedly at the stripped-down interior of the former military helicopter. The sun was low on the horizon outside, flooding the interior with ruddy morning light. His jaw tightening, Stone blinked a few times before apparently forcing himself to relax.

By his own account, the dream was always the same, its familiar images having solidified over the years into a kind of half memory. Stone described it as a gruesome stream of blood, wine-dark, flowing over white desert sand. The spreading stream stopped, suddenly still, wrong somehow, as the surface of the blood seemed to congeal all at once, the gleaming slick shrinking in on itself and solidifying into tiny grains of ocher dust—fine particles of dried blood that swirled up and away on the oven-hot breath of desert wind.

Stone shook his head to clear it.

Putting the dream out of his mind, he focused on the brightening jungle outside. He must have felt a sense of raw anticipation. As a child raised by a daredevil scientist, he had finally, at the start of his fifth decade, found himself joining an adventure to rival his father’s.

Briefing documents lay spread out on the empty seats beside him, covered in dire warnings and classifications. Among them was a stiff, waxy photograph accompanied by a few pages of technical readouts.

It was truly a stunning image.

The ultra-high-resolution picture had been created by the army’s adaptive super-resolution image reconstruction algorithm, which combined multiple video frames, still images, and radar-generated topographical information to construct a three-dimensional image and paint it with light in spectacular detail.

Even so, it still looked like a hoax.

The structure reminded Stone of his trips to the ancient Mayan temples of Guatemala and the Yucatan Peninsula. How the surprisingly intact rock edifices peeked their heads out of misty jungles, like giants frozen midstride over a primal landscape that had grown up around them.

Similar, except that the appearance of this particular structure had triggered the scrambling of an international coalition of esteemed scientists to the most remote jungle on the planetary surface. It was apparently worth hiring a black-market chopper for a surely outrageous price, and sending a trio of polite but firm active-duty soldiers to retrieve Stone from a guest lecture before a college class, midsentence, confiscating his phone and firmly escorting him away.

And yet Stone had only glanced at the glossy image. The structure was obviously interesting, but it wasn’t what had piqued his curiosity. That would have been the other readout:

MASS SPECTROMETRY RESULTS

/// These data were collected by [redacted] High-Resolution Spectral Analysis suite and are intended for AFSPC USE ONLY. ///

*** UNAUTHORIZED USE PROHIBITED. CLASSIFIED TOP SECRET—DISSEMINATION IS SUBJECT TO CRIMINAL PENALTIES INCLUDING SUMMARY EXECUTION WITHOUT TRIAL ***

Unknown reading /// Unknown reading. N2. Saturation. /// Composition analysis …

… Incident in PIEDMONT, ARIZONA. MATCH *** MATCH *** MATCH ***

The atmospheric readings were startling in that they very nearly replicated the exact composition of air rising off the sunbaked plains of Piedmont, Arizona, in the aftermath of the Andromeda incident.

And with that, a haunting name was invoked:

PROJECT WILDFIRE * PROJECT WILDFIRE * PROJECT WILDFIRE *

The words would have undoubtedly caused deep, conflicting feelings in Stone. Over fifty years before, his father had played a significant role in stopping the spread of the Andromeda Strain. While under preliminary consideration for inclusion on the Wildfire roster, James Stone had been given access to a slew of classified documents. He had used the opportunity to pore over every detail of the incident—and especially his father’s part in it.

Yet to try and discuss it with the old man would have been impossible—literally illegal.

In all the years of traipsing around the globe together, there is no indication the father and son ever conversed about what happened in Piedmont. With his balding crew cut and thick-framed glasses, Dr. Jeremy Stone seemed never to have left behind the 1950s tradition of stoicism. He took his top-secret status very seriously. Jeremy Stone did not speak of the classified portions of the events that occurred during that five-day period—not to his son, not to any of his ex-wives, not to anyone else in his life.

The father was distant, and yet in many ways the boy worshipped him.

As an adult, James had grown up to be quite distinct from his thin, balding father. Tall and athletic, the younger Stone had a head of thick dark hair (graying now) and a quiet, driven personality. He had reached the highest level of professional success as a roboticist and artificial intelligence expert. Where his father had operated within the hallowed traditions of academia, James had become an industry darling, a perpetually single workaholic who consulted across a variety of high-tech corporations—both start-ups and venerable institutions—wielding a razor-sharp intellect to collect massive paydays.

The elder Stone passed away still a bachelor, having married (twice to the wives of his colleagues) and divorced four times. James Stone apparently decided to forgo the entire process, never marrying or having children of his own. Despite their differences, James was his father’s son in so many ways.

According to Stone, after receiving contingent approval to join the modern-day Project Wildfire early in his career, not telling his father about it was one of the hardest things he had ever done in his life.

But it’s exactly what his father would have done in his place.

THOUGH RECORDS OF the Sikorsky H-92 pilot and copilot do not exist, word of mouth indicated that they were Brazilian narcotraficantes—subjectively a pair of criminals, but objectively the best in the world at navigating the largely unpoliced cross-basin routes favored by the Colombian cartels.

The pilot did not understand why he was flying an americano, much less during the daytime; he also did not know of the huge, unmarked cash payment made to his superiors; and he was not completely sure he would make it out of this job alive.

This last concern was actually quite valid.

At Peterson AFB, the Sikorsky was under constant surveillance. An F-35B Lightning II stealth fighter had been hastily launched from just off the Pacific coast, where it was stationed aboard the Nimitz-class aircraft carrier USS Carl Vinson (CVN-70). The carrier strike group had been dispatched under the guise of a joint American and Peruvian emergency response exercise. If the Sikorsky helicopter were to show any sign of contamination, the high-altitude fighter was one trigger word away from launching a bevy of AIM-120 AMRAAM long-range air-to-air missiles.

The helicopter pilot was unaware of this information, but certainly suspected something was wrong. Wisely, he chose not to deviate from the prescribed course in the slightest—despite what was about to unfold.

“Agora, nos descemos,” the pilot said to the American. “Brace. Brace yourself.”

In the cabin, James heard the static-filled voice of the pilot over his headphones.

“Why here?” he replied, scanning the unbroken jungle below. “We need to be closer.”

“Quarantena. Thirty miles.”

Quarantine zone. So the government had learned something since Piedmont. If the AS-2 plastiphage microparticle were airborne near the site, it could infect low-flying aircraft. In recovered cabin video, James can be seen hastily checking the rubber of the window gasket—running a finger along the soft plastic seal and examining it.

Still intact.

The second evolution of the Andromeda Strain, called AS-2, was known to dechain the polymers that made up synthetic rubber, especially the early blends synthesized before the microparticle had been studied. And although the information was classified, James Stone knew that Andromeda still permeated the nitrogen-rich mesosphere high above them.

Stone exhaled a deep breath.

If an AS-2 strain had infected the helicopter, he’d know it already. With vital engine parts disintegrating, they would have careened into the jungle and died in a crunch of metal and dirt—as had the unfortunate pilot of the F-40 Scavenger jet that had streaked over the Piedmont site after first contact. Or like the Andros V spacecraft, which had come crashing down in a fiery blaze on February 17, 1967, its tungsten-and-plastic-laminate heat shield turned to sterile dust.

Confident that his fiery demise wasn’t coming in the next few seconds, Stone turned to what lay beyond the window. Everything outside was Terra Indigena—mile after mile of government-protected land. He wondered whether the Brazilian government had even been informed of this mission.

He doubted it.

Stone caught sight of a plume of red smoke outside, rising from a clear-cut patch of jungle near a riverbank. A smallish, recently constructed maloca hut sprouted from the center of the clearing, surrounded by hacked vegetation and fallen trees.

It looked like a scar to Stone, a cigarette burn on the face of the pristine jungle.

To the pilot, however, the clearing looked like the only landing pad within five hundred miles. Flying past and gaining altitude, he wheeled the bird into a wide circle to surveil the area and alert the people below that he would be coming in for a landing.

In the audio logs, a burst of confused and frightened dialogue can be heard ricocheting between the pilot and copilot. Three seconds later, the pilot yanked the control stick and dropped the Sikorsky into a stomach-churning descent. The anomaly was barely discernible on the horizon. But for an instant, something else had been briefly visible in the treetops—still several miles away.

Stone clearly saw it, too.

“Wait!” he called over the radio. “What was that? In the trees?”

The chopper only sank faster, spiraling, rapidly losing altitude.

“Go. Now!” the pilot shouted at Stone, tapping his copilot.

The copilot climbed back into the cabin, reaching across Stone’s lap and unceremoniously yanking open the rolling side door. Shrinking back, Stone saw they were still a hundred feet up. Outside, a roaring mass of jungle canopy shuddered under the pounding rotors, and the cabin was filled with a wash of humid air.

Craning his neck, Stone was able to snatch a final, puzzling glance of the bizarre scene in the distance.

Then the Sikorsky sank below the tree line, jolting onto the ground, tires bouncing on the red mud of the clearing. As the helicopter settled, the pilot left the controls and joined his copilot in the cabin, rushing to detach Stone’s luggage where it was secured in webbed fabric. They ignored the American, shouting to one another in Portuguese, leaving the engines running and the rotors spinning.

Stone still could not quite understand what it was he had seen.

It appeared at first to be a wave of darkness washing over the tree canopy. A swarm of black shapes, thrashing like a school of salmon going upstream—a ripple of movement under the electric green foliage.

“Senhor!” shouted Stone, over the noise of the rotors. “What was that? Were they—”

Stone’s voice cut out as the pilots turned to him.

It was the naked fear on the faces of what he would later describe as “hard men” that took Stone’s breath away. And at that moment, some symmetry in the twisting shapes he had seen coalesced in his mind.

The pilot and copilot tossed out Stone’s black hard-case luggage. Stone hastily gathered his papers, snatched up his duffel bag, and got to his feet. He stood in the open doorway for a moment, a lean silhouette against the crimson sunlight outside.

Stone turned to the pilot, his voice hollow as he spoke. “Those were monkeys, weren’t they? Swinging through the upper branches in a panic. Hundreds of them. A thousand.”

The pilot said nothing, emotionless behind mirrored sunglasses. Without warning, his copilot took hold of Stone’s shoulders and roughly shoved him through the helicopter door. He tumbled out and fell to his knees on the muddy ground.

The Sikorsky had already lifted off before Stone could get to his feet.

Boots on the Ground

DR. NIDHI VEDALA WAS ANGRY. AND IMPATIENT. SWATTING at a mosquito with one hand, she heard the thundering approach of the Sikorsky H-92 and her dark eyebrows knit together in a frown. The makeshift clearing around her was scattered with muddy black hard-case luggage, each containing precious equipment that needed to be checked for damage. The noise and commotion of incoming rotors sent squawking birds streaking past her and startled a young caiman on the riverbank into the water.

She ignored it all, consciously forcing herself to unclench her fists and continue inspecting the hard-cases. The jungle didn’t frighten her. Not much did.

Vedala had grown up an orphan in the Morarji Nagar slums of Mumbai, a member of the Dalit social caste—called the “untouchables,” often beaten and discriminated against. Though impoverished, she saw the world with the clear focus of a naturally keen intellect. Even as a bone-thin child under a mop of reddish-black hair, she never had a doubt that she would someday escape the narrow alleyways, fetid community toilets, and sickening miasma of the toxically polluted Mithi River.

During her first round of mandatory statewide merit testing, Nidhi had come away with the top score out of approximately fifteen million school-age Indian children. Starting from nothing, she had painstakingly earned her place among these distinguished scientists on this high-stakes mission.

The leader of the expedition and a founding member of the next generation Project Wildfire, Vedala had been dragged away from her laboratory at the Massachusetts Institute of Technology by armed goons, driven an hour to Hanscom Air Force Base, and placed on board a wildly inappropriate C-130 Hercules military jet. Her mobile phone and laptop were confiscated, along with her identification. The cargo plane had been fueled up and waiting on the tarmac, but still set in an armored vehicle transport configuration, with only a few jump seats available for passengers.

None of this had startled her in the least.

Vedala was a small woman with an impish face and an efficient pixie haircut. She often scowled while concentrating, unconsciously intimidating others. She wasn’t tall, but nonetheless projected a large presence, and her military escort quickly decided to retire to the cockpit up front with the two pilots and loadmaster. For the next twelve hours Vedala sat alone in the cavernous belly of the great beast, sleeping occasionally, but mostly rereading a fat red packet of files by the stark glow of the interior floodlights.

From the first moment, she understood that only one type of threat could possibly justify this level of expenditure—it had to be a global crisis with existence-level repercussions. A true world-ending scenario.

And Vedala welcomed it.

This was, after all, exactly the situation to which she had devoted her career. A materials scientist with a nanostructure specialty, she had spent her public life rising meteorically through the ranks of academics.

Her relentless exploration of new metamaterials had exploited the quirks of quantum mechanics to miraculous effect. Among the many discoveries made in her laboratory were novel materials that could absorb electromagnetic energy to render a perfect retina-draining blackness, or allow light in the visible spectrum to slide away entirely in a blurry sort of invisibility cloak, or imbue a surface with perfect smoothness, a near-zero friction to which no viscous liquid could stick.[fn1]

But Vedala’s true career had not taken place in the public eye.

Early on she had been approached by a major general in the US Air Force, an ambitious former fighter pilot named Rand L. Stern who had transitioned to a faculty position at the US Military Academy at West Point with a specialization in theoretical mathematics.

At that time in her life, Vedala hadn’t known that academics and the military could mix. But the determined general wouldn’t be ignored. He told Nidhi that her expertise was needed for a historically momentous project, and all she had to do was sign on the dotted line. He mentioned she had already passed every background check and intelligence test that his analysts could administer.

Vedala had only blinked at this information.

She had not been aware that she was under any scrutiny. Now, she wondered at just how specific the New York Times crosswords had been getting the last few weeks, and she began to question the increasingly complex problems her graduate students had been bringing to their office visits.

In any case, Vedala had never failed a test in her life.

Choosing to accept Stern’s offer of military clearance, she had listened intently to every detail of the incident in Piedmont, Arizona. When it was over, she understood her role perfectly.

At first assumed to be an organism, the Andromeda Strain actually seemed to have more in common with a new area of science—nanotechnology, the study of machines less than one hundred nanometers in size.

Vedala had devoted her career to understanding the topography of nanoscopic structures, and the construction of artifacts small enough to fit on a pinhead (along with however many angels wished to dance there). She knew there was vast potential waiting for humankind in the realm of nanoscale. After a single conversation with Stern, it became her life’s work to understand this mysterious extraterrestrial microparticle.

So far, her studies had been a resounding success.

Vedala’s most brilliant insight had been to expose the two varieties of Andromeda to each other. Studying the results at a nanoscale, she discovered that each strain ignored the presence of the other. As close cousins, the substances seemed to have entered into a kind of noncompete agreement.

Essentially, AS-1 and AS-2 were invisible to each other.

Realizing this, Vedala had been able to mass-produce a spray coating with a nanostructure mimicking the contours of both Andromeda strains, creating a surface that was nonreactive to both. Vedala’s brilliance did not extend to naming her creation, however; the antibonding mechanism was dubbed simply “aerosolized nanocrystalline cellulose-based Andromeda inhibitor.”

The inhibitor had been utilized so far to protect low-orbit spy satellites and government rocket launches from atmospheric AS-2. This represented humankind’s first mastery over the strange, plastic-eating microparticle after decades of highly classified study in the laboratory. Now the time had come for Vedala to test her creation face-to-face against the first documented “wild” appearance of Andromeda. And she did not intend to fail.

It was nearly noon. Every other member of her team had already arrived, whisked away from their respective lives to the middle of the Amazon jungle.

All of them had been on time, except for one: James Stone, PhD.

As a roboticist, Stone’s skills were not mission appropriate. In Vedala’s estimation, he should have been replaced with a microbiologist or a bacteriologist. Any number of more multidimensional researchers would be better suited. And yet General Stern had been intransigent on Stone’s inclusion.

Standing beside a muddy river with no name, Vedala knew the stakes of this mission. She also knew its legacy. And thus she had her own idea of why James Stone had been forced onto her roster.

As Stone gathered his luggage, Vedala spit on the ground, turned, and walked away to inspect the hard-cases.

Vedala was an orphan and a self-made success. Her assumption was that James Stone, son of the famous scientist Jeremy Stone, had been included on her field team for a reason she could fundamentally never respect—his family pedigree.

Noon Field Briefing

PENG WU WATCHED THE THREE OTHER SCIENTISTS gather and check their luggage in the hacked clearing without saying a word. Though she of course spoke perfect English, and French and German for that matter, she found silence almost always to be the best response around her European and American colleagues. She had read the dossiers on her team (both the American and the Chinese People’s Liberation Army–supplied documentation), but had met them each just briefly.

Only the older African man, Harold Odhiambo, made her feel comfortable. He spoke slowly and with deliberation. And though he often wore a wry grin below thick round eyeglasses, he refrained from constantly flashing his teeth in glaring and pointless smiles.

Peng knew that with her keen intellect and piercing black eyes, she could appear severe to Westerners, especially civilians. She wasn’t bothered by it. In her estimation, their discomfort was due less to a cultural divide than to the simple fact of her military background and natural disposition.

When she was a small child in Zhengzhou, Peng’s parents were often gone—dispatched on various assignments for the PLA. Left in the care of her grandfather, she had begun to experience separation anxiety that soon blossomed into panic attacks. As a solution, the old man had introduced his granddaughter to the ancient game of weiqi (known as Go in the United States). He explained that life was like the game—and every word spoken, every emotion betrayed through gesture or expression, constituted a move. By controlling each of your moves, you could reduce anxiousness and win the game.

Peng Wu found that she very much liked winning, at weiqi and at life.

From those years on, Peng’s strategy had been to reach her goals in the fewest number of moves. Rising through the ranks of the People’s Liberation Army and undergoing intensely competitive astronaut training, she had learned to suppress her anxiety by choosing her actions carefully, and always with the express intention of accomplishing the mission. In this way, she had strategically chosen to marry an ambitious fellow soldier and had gained the full trust of her government and the military.

Peng turned her attention to a group of a dozen frontiersmen—native jungle specialists who had been hired to clear this landing area and accompany the field team on their expedition into the Amazon. The brown-skinned men blended traditional tribal adornments with modern military equipment. They worked together as a team with wordless efficiency, using the natural resources on hand to craft a base camp out of the raw clearing. Every step, every swing of the machete, was done with a familiar ease that spoke of lifelong jungle experience.

Meanwhile, the civilian scientists were still adjusting to life without their smartphones or the Internet.

Methodically breaking down her traveling backpack to separate out the extra scientific goods that could be hauled by one of the native porters, Peng resolved to stay close to the guides—doing so would maximize her survival probability and therefore the success probability of the mission as a whole.

“FINALLY, WE’RE ALL here,” said Vedala.

The Indian woman barely glanced in the direction of James Stone as he stomped across the muddy clearing, huffing and puffing, dragging a black plastic hard-case full of equipment. Wearing a brand-new khaki outfit, the roboticist was in his early fifties but looked younger. His face was already sweaty in the oppressive heat of high noon.

“Let’s begin,” she added.

Vedala stood under the low ceiling of a maloca—a simple thatch-roofed hut the guides had hastily constructed beside the gurgling brown river. A paper topographic map was spread across a folding table and weighted at the corners with muddy stones. Across from her stood the immaculately outfitted Peng Wu. The PLA Air Force major stood perfectly straight, with martial precision, trim and athletic in a long-sleeved jacket and khaki pants neatly tucked into her boots.

With her military bearing, Peng stood out in stark contrast to the much older Harold Odhiambo, a robust Kenyan man with close-cropped salt-and-pepper hair, a gently amused attitude, and a disheveled outfit complete with cargo shorts and an Australian bush hat with one side pinned up.

Odhiambo turned his kind eyes to Stone as the bedraggled man joined the group under the thatch roof.

“Welcome, Dr. Stone,” said Odhiambo, with an English accent. “I enjoyed your work on collision avoidance using low-resolution imaging. Very efficient.”

Stone was speechless for a moment, surprised that the famous xenogeologist would have bothered to read his work. Then he recalled that Odhiambo supposedly read everything, and with that, his manners returned.

“Thank you, Dr. Odhiambo. That’s very flattering. I apologize that I haven’t caught up with your latest—”

Vedala cut in.

“You can take that offline. Harold has dabbled in just about everything over his career,” she said. “Which is why he’s perfect for our mission. He’s not just a specialist.”

The words hung in the air long enough to be awkward before a modulated ringing interrupted.

“Back to the agenda,” she added.

Vedala picked up an Iridium satellite phone from the table. The chunk of black plastic was a restricted military model commissioned by the Defense Information Systems Agency (DISA). It had been ruggedized, weatherproofed, waterproofed, signal-encrypted, and fitted with a hot-swappable antenna adapter. Currently it was attached to a thin black antenna wire strung around the wooden poles supporting the hut. The ice-blue LED screen glowed coolly in the heat of the jungle, four out of four connection bars illuminated.

“Dr. Sophie Kline is joining us from the International Space Station,” Vedala said, depressing a button to answer the call. “Good afternoon, Doctor, how’s the view from up there?”

“Beautiful, Nidhi, and not a single mosquito.”

The voice on the speakerphone was confident and feminine, but a few lightly slurred syllables and a slight tremor betrayed its owner’s neurodegenerative disease. “I’m over top of you now, but in a few minutes my orbit will carry me beyond the horizon again and our comms may not be so clear.”

Looking at her crew, Vedala continued. “I assume you’ve all read my personal briefing letter, as well as the red folder docs sent by the Department of Defense—”

James Stone raised his hand, and Vedala stopped, lips pursed in annoyance.

“Yes?”

“Sorry to interrupt, Dr. Vedala, but I didn’t get a briefing document.”

Vedala blew a curl of hair away from her eyes in irritation. “No, of course you didn’t. You were a … late addition.”

“Oh, I didn’t know—”

“It’s not your fault,” she snapped, more abruptly than she meant to. “Our fearless leader, General Stern, approved the final details of this expedition, and I’m not privy to all the information he had. You can pick up the details as we go—it’s almost time to start the day’s march. This is Project Wildfire, so you all understand the stakes.”

“The fate of the world …” Odhiambo smiled.

“You may not be far from the truth,” said Vedala. “Agenda item number one, let’s talk situational background. Twenty-six hours ago a terrain-mapping drone detected a … structure in the deep jungle, thirty miles from here. This anomaly is two hundred feet tall, and it appeared within the last two weeks in the middle of impassable jungle, without any known roads or a landing strip. And now for the reason we’re here. Subsequent mass spectrometry readings detected a chemical fingerprint closely matching the original Andromeda incident. Any questions?”

“Another outbreak,” said Odhiambo, in a thoughtful voice. “But why would it be located here, so far from anything else?”

Kline’s voice came in over the satellite phone: “The Chinese Tiangong-1 space station broke up in the atmosphere over Brazil six months ago. It spread bits of wreckage between here and the Atlantic Ocean. We think … ah, the Americans think, the Chinese may have been experimenting with Andromeda.”

Peng seemed to have been waiting for this. The former soldier kept her face blank as the others looked to her. Kline’s accusatory tone had not gone unnoticed, and Peng’s response seemed prepared as she spoke.

“Of course I have no official knowledge of this,” said Peng. “However, it would not be an unprecedented scenario, considering the many international efforts under way to study Andromeda in a microgravity environment.”

Vedala nodded, half smiling. Peng was making a pointed remark about the existence of the Wildfire laboratory module on board the ISS, but she was at least willing to acknowledge the reality—an infected sample from the fallen Chinese space station could have contaminated the jungle.

“Regardless of how the anomaly got here, we are facing the reality of a large structure growing in the middle of the jungle with a chemical composition that matches Andromeda. Our plan is to hike into the quarantine zone and find out what this thing is before it gets any bigger. Thanks to the last Project Wildfire, we know a lot more than the people who tried this in Piedmont. Our respirators and inhibitor spray will protect us, and we have toxin detectors operating constantly.”

“I’m surprised the feds didn’t already nuke it on reflex,” said Stone, venturing a joke.

Vedala only scowled. “And start a world war? We’re not in the United States, Dr. Stone. The contamination didn’t appear in our own backyard this time around. We weren’t that lucky—”

At these words, Vedala noticed a change in Stone’s demeanor. He looked away at once, cheeks flushing with anger. She immediately realized how callous her words must have sounded.

“Obviously, what happened in Piedmont wasn’t lucky. But this incident is happening in one of the most ecologically delicate places on the planet, severely limiting our options. We’re in protected indigenous territory, a place where by Brazilian law uncontacted tribes are meant to be left alone. Harold can elaborate.”

“She’s right,” said Harold Odhiambo, addressing the group. “This is Terra Indigena. The indigenous people who live here are isolated, surviving quite comfortably at a mostly pre–Stone Age level of technology.”

Harold spread his long arms, gesturing at the trees.

“We are standing in Earth’s lungs. These tree species spread their roots wide and shallow, cutting off almost all access to bedrock. The people who have lived here for millennia never had the opportunity to develop stone tools. Even their arrowheads are carved from bamboo, completely biodegradable. They have been spared the never-ending progression of technology.”

“You say that as if progress is a bad thing,” said Peng, quietly.

“It is not a bad thing … until we show up. Exposed to superior technology, these tribes are vulnerable to being exploited, killed, or enslaved. In the best-case scenario, they will covet our technology—especially our steel and guns. When they do get hold of it, they forget the traditional ways of living and become dependent on tools they can’t reproduce. Any contact, with good or evil intentions, will destroy them. Outsiders either take their lives, or their way of life.”

Odhiambo’s manner had turned grave.

“Our presence in the jungle is highly dangerous. History has played out the same way across every continent, from the indigenous people of Africa to those of Australia and the Americas. It always ends in death.”

“And that’s why we’re not contacting anybody,” said Vedala, pointing to the tree line where the quasi-military men were waiting. “Those are our guides, and they’re going to keep us far away from the locals.”

The dozen uniformed men had collected in shady spots around the edge of the clearing, standing or squatting and talking quietly to each other. From a distance they looked like soldiers, wearing camouflage, with machetes hanging from their hips and shotguns casually strapped over their shoulders.

But looking closer, Stone could see they were indigenous, their crisp military uniforms complemented by traditional clamshell earrings that stretched their earlobes and stiff bamboo shoots poking from their nostrils like jaguar whiskers. Most of the men had waves of bluish lines tattooed across their upper cheeks and thick black hair chopped in bowl cuts.

“Are they not Indians?” asked Peng.

“Those are Matis frontiersmen,” responded Vedala, “and they know this territory well. Until forty years ago, they were one of the uncontacted tribes.”

Vedala nodded to a large man with a sweat-stained green shirt neatly tucked into military fatigues. Unlike the others, this soldier was Anglo, and he carried a high-tech battle rifle strapped over his chest. The weapon appeared well-used, bristling with after-market attachments.

“And the final item on our agenda,” said Vedala. “Meeting our guides.”

As if on cue, the soldier stood and began to stride toward them, heavily muscled arms swinging. The bearded Brazilian American spit out a toothpick as he approached the group, snapping words at them with a Portuguese accent.

“Listen up, people. My name is Sergeant Eduardo Brink, United States Army Special Forces. I have been instructed by General Stern to handle you with kid gloves. But this is the Amazon wild. This jungle does not care for your credentials. It does not care for your intelligence. Or for your technology. It was here before you and it will be here after you are gone.”

“If we’re lucky,” muttered Stone.

Brink flashed a cold stare down at the roboticist before continuing. “You are already deep into the territory of indios bravos, wild Indians of Brazil. Make no mistake. You are not welcome. It is sheer luck that I was stationed here with FUNAI and available to accompany you. Our rendezvous with command is in forty-eight hours, at the prescribed destination. If we are not there, command will assume we were killed in action and proceed with alternate plans. My job is to get you where you’re going, on time … alive.”

Brink’s voice lowered, and he stepped closer to Stone.

“And let me be very clear, amigo … without me, you will die here.”

The group of scientists exchanged worried glances, and the sergeant seemed satisfied. Turning, he spoke rapid-fire to the native soldiers, who tossed away cigarettes and rose to their feet. Some pulled tumplines over their foreheads, using the woven straps to carry luggage while leaving their arms free. A few others set off into the jungle without a word. The whistling snaps of machetes were audible as they set about hacking a new path through the dense wall of undergrowth. Brink turned back to the scientists, pulling a toothpick from his shirt pocket and clenching it between his teeth in a wide, menacing smile.

“You don’t have to like me, boys and girls. You just have to obey me. Because the very last thing you want is to end up out here all alone.”
