Slingshot

Chapter 1: The Commission

The hearing room smelled like recycled air and old decisions.

Alejandra Cruz sat in the hard plastic chair with her hands flat on her thighs, watching the panel of six administrators shuffle documents they'd already memorized. Behind them, a wall-sized display showed Earth in real time—the bloated brown smear where Miami had been, the gray haze over the Pearl River Delta, the white blister of the Antarctic melt shelf calving into water that had nowhere to go except into someone's living room.

She knew what they saw when they looked at her. A forty-three-year-old pilot with a scar that ran from her left temple to her jaw, a medical file flagged for post-traumatic stress, and a docking record that included the words "loss of crew" in bold red type. She was the woman who'd killed four people at Shackleton Station by misjudging a thruster pulse by eleven milliseconds.

Eleven milliseconds. The time it takes to blink.

"Commander Cruz," said Director Haruna Obi, a compact woman with silver-threaded locs and the kind of patience that came from managing a bureaucracy on the edge of collapse. "You understand why you're here."

"You're out of pilots," Alejandra said.

A ripple of discomfort moved through the panel. She wasn't wrong, and they all knew it. The qualified deep-space pilots who hadn't emigrated to the Martian cooperatives or drunk themselves into medical disqualification could be counted on two hands. The ones willing to fly a patched-together mining tug on a fourteen-month intercept of an interstellar object moving at forty-one kilometers per second—that list was shorter.

That list was her.

"We prefer to frame it as recognizing your unique qualifications," Obi said, with the ghost of a smile.

"My unique qualifications include a fatal accident on my record."

"Your unique qualifications include seven thousand hours of deep-space piloting, three successful asteroid-capture operations, and the fact that you kept the crew of the Kestrel alive for forty-one days on a crippled vessel with no functioning life support beyond what you improvised from cargo packaging." Obi leaned forward. "Shackleton was a tragedy. It was also, according to the review board's final determination, a mechanical failure that no pilot could have fully compensated for. You were cleared."

"Cleared isn't forgiven."

The room was quiet for a moment. On the display behind the panel, a storm system the size of Europe churned across the Indian Ocean.

"Let me show you something," Obi said, and touched her tablet.

The Earth vanished. In its place appeared a grainy image—a smudge of light against the star field, taken by the Mauna Kea array six weeks earlier. It didn't look like much. A comet, maybe. A bit of cosmic debris tumbling through the void.

But the spectral data overlaid on the image told a different story. Water ice. Nitrogen. Ammonia. Methane. Rare volatiles that the orbital refineries would kill for. And the mass estimate, refined by three independent observatories and confirmed by radar bounce from the Goldstone array: somewhere north of one trillion metric tons.

ʻAuʻau. The Wanderer.

"It entered the solar system on a hyperbolic trajectory eight months ago," Obi said. "It's not bound to the sun. It's passing through, and in fourteen months it will be gone. Permanently. There is no second chance."

Alejandra stared at the numbers. A trillion tons of water ice. The orbital colonies were rationing at four liters per person per day and falling. The hydroponic stations at L4 and L5 had lost thirty percent of their crop yield in the last year. Children were developing bone disorders from mineral deficiency. Old people were dying of dehydration in stations that floated above an ocean they couldn't reach because the launch costs made it cheaper to let them die.

A trillion tons.

"The mission profile is straightforward in concept," Obi continued. "Intercept. Anchor. Fragment. Redirect a manageable piece into a stable Earth orbit where it can be harvested over decades. The tug Persephone has been retrofitted for the task."

"The Persephone," Alejandra said flatly. "That's the old Kuiper survey vessel. The one they decommissioned after the reactor housing cracked."

"Repaired."

"Repaired by whom?"

"Elijah Watts."

Alejandra's eyebrows rose slightly. Watts was a name she knew—a reactor whisperer, the kind of engineer who could keep a fission pile running with spit and prayer. He'd kept the Calloway Platform operational for three years past its rated lifetime, which was either genius or insanity depending on who you asked.

"The crew is six," Obi said, and listed them. Dr. Boris Lebedev, geologist, Russian Academy of Sciences, specialist in extraterrestrial mineralogy. Fern Beckworth, medic and botanist, formerly of the ESA agricultural program. Diego Salvador, navigator, formerly of—Obi paused delicately—"the private sector."

"He's a gambler," Alejandra said.

"He's the best orbital mechanics mind we could find who wasn't already contracted to the Martian cooperatives. He reads trajectories the way some people read music."

"And the sixth?"

"Conrad Slate. Corporate observer, representing the Palladian Resource Consortium. They're funding forty percent of the mission. Mr. Slate ensures their investment is protected."

Alejandra felt the familiar weight settle onto her shoulders—the weight of other people's lives, other people's agendas, other people's money. She'd carried it before. She'd dropped it once, and four people had died.

"When do we launch?"

"Seventeen days."

She almost laughed. Seventeen days to familiarize herself with a ship she'd never flown, a crew she'd never met, and a mission profile that assumed everything would go right in an environment where nothing ever did.

"Commander Cruz," Obi said, and her voice carried the weight of the drowning world behind her. "I won't pretend this isn't dangerous. I won't pretend the ship is ideal or the timeline is comfortable. But that object out there is the single largest concentration of accessible water humanity has ever encountered, and it is leaving. Every day we deliberate is a day of delta-v we cannot recover. The orbital colonies have eighteen months of reserves. If we don't bring that ice home, people will start dying in numbers we can't hide behind statistics."

Alejandra looked at the smudge of light on the screen. Somewhere out there, beyond the orbit of Jupiter, a mountain of ice was tumbling through the dark, indifferent to the species that desperately needed it.

"I'll need full authority over mission decisions," she said. "No committee overrides. No corporate vetoes."

"Agreed."

"And I want to meet the crew before I commit. All of them. Including Slate."

Obi nodded. "They're assembling at Tycho Dock. The Persephone is there."

Alejandra stood. Her knees ached—too many years in variable gravity—and the scar on her face pulled when she set her jaw, which she did now, because it was the only way she knew how to face the thing she was about to do.

"One more question," she said.

"Yes?"

"If I bring them home alive and empty-handed—if the mission fails but the crew survives—is that acceptable?"

Obi's expression didn't change, but something shifted behind her eyes. "Bring the ice, Commander. That's the mission."

"That's not what I asked."

A long pause. "Bring them home alive," Obi said quietly. "Whatever else happens. Bring them home."

Alejandra nodded once, turned, and walked out of the hearing room into the corridor of Tycho Station, where the recycled air tasted like metal and the gravity was point-three-g and the future of ten million people in orbit depended on a cracked ship, a broken pilot, and a comet that wouldn't wait.

---

Tycho Dock smelled worse than the hearing room—lubricant, ozone, and the particular funk of a station that had been running over capacity for a decade. Alejandra made her way through the press of bodies in the main concourse, past the water vendors with their armed guards, past the children playing in the low gravity with the hollow-cheeked look of kids who'd never tasted real fruit, past the news feeds cycling through the same loop of catastrophe: Jakarta underwater, the Colorado River Compact collapsed, the Saharan Solar Array destroyed by militia action, the L5 Greenhouse Collective reporting another failed harvest.

The Persephone was berthed in Bay Seven, and Alejandra's first sight of her was not encouraging.

She was a hundred and twelve meters long, built on the old Kuiper-class frame—a central spine with modular compartments bolted on like barnacles. Her hull was a patchwork of original plating and newer panels that didn't quite match in color or composition. The main engine bell, a magnetic confinement fusion drive rated for twelve months of continuous operation, showed the scars of at least three major overhauls. The radiator arrays—massive panels designed to shed waste heat into space—extended from her midsection like broken wings, and even from the observation gallery Alejandra could see where they'd been repaired with what looked like salvaged material from at least two different vessel classes.

She looked like a ship that had been loved too hard and maintained too little. She looked like every deep-space vessel Alejandra had ever flown.

She looked like a death trap that might just work.

"Beautiful, isn't she?"

Alejandra turned. The man leaning against the gallery railing was tall and thin, with skin the color of burnt copper and hands that were permanently stained with reactor coolant. He wore a jumpsuit with the name WATTS stenciled across the breast pocket and a smile that suggested he found the universe fundamentally amusing.

"Elijah Watts," she said.

"Commander Cruz. I've been expecting you." He nodded toward the ship. "I know what you're thinking. She looks rough."

"She looks like she should be in a museum."

"Museums don't have the budget to take her. But I've gone through every system personally. The reactor's solid—I rebuilt the containment vessel myself. She'll give us the delta-v we need, as long as we don't ask for more than she's got."

"How much has she got?"

"Enough. Barely. The mission profile has about four percent margin, which is—"

"Suicidal."

"—tight," he finished, still smiling. "But workable. I've flown on less."

"So have I. It's not an experience I recommend."

Watts pushed off the railing and fell into step beside her as she walked toward the boarding tube. "The others are aboard. Lebedev's been here for three days already—he practically lives in the geology lab. Beckworth arrived yesterday with two hundred kilograms of soil substrate and a look on her face like she was moving into a condemned building, which, fair enough. Salvador got in this morning. And Slate—" Watts paused. "Slate's been here since before any of us. He had his own access codes."

"What do you make of him?"

"Corporate. Polished. Asks a lot of questions about the engine specs and doesn't share what he learns. I don't trust him, but I don't trust anyone who wears a suit in space."

They entered the boarding tube, and the smell changed—older, mustier, the particular scent of a ship that had been sealed and reopened too many times. The interior of the Persephone was cramped but functional, every surface covered with handholds, every compartment labeled in three languages. The lighting was harsh LED, the kind that made everyone look slightly ill.

Alejandra ran her hand along the corridor wall as they walked. She could feel the ship through her fingertips—the faint vibration of the life support systems, the hum of the electrical grid, the almost subliminal pulse of the reactor in standby mode. Every ship had a heartbeat. This one's was steady but old.

"Introduce me," she said.

---

Dr. Boris Lebedev was in the geology lab, surrounded by screens showing spectral analyses of ʻAuʻau. He was a large man, broad-shouldered and thick-necked, with a gray beard that needed trimming and eyes that burned with the particular intensity of someone who had found the thing they'd been looking for their entire life.

"Commander," he said, barely looking up. "Do you know what this object is?"

"A very large piece of ice that we need to bring home."

"It is a messenger." He turned one of the screens toward her. "The isotopic ratios in the spectral data—they don't match anything in our solar system. The deuterium-to-hydrogen ratio is consistent with formation in a protoplanetary disk around a K-type star. This ice was made around another sun, Commander. It has traveled for millions of years, perhaps hundreds of millions, and now it passes through our system for the first and only time. What it can tell us about the chemistry of other star systems, about the conditions for life elsewhere—"

"It can tell us all of that after we've harvested it and brought it home," Alejandra said. "Your job is to identify the best extraction sites and oversee the fragmentation process. Can you do that?"

Lebedev's jaw tightened. "I can do that. But I want it on record that treating this object as nothing more than a water tank is scientifically criminal."

"Noted. And Boris?" She waited until he met her eyes. "On this ship, I give the orders. Not the science. Not the schedule. Not the corporate sponsors. Me. Are we clear?"

He held her gaze for a long moment, then nodded. "Clear, Commander."

Fern Beckworth was in the hydroponics bay—a converted cargo hold that she had transformed into a miniature garden. Grow lights cast a warm spectrum over trays of lettuce, spinach, radishes, and herbs. A small section held strawberry plants, their white flowers incongruously cheerful in the utilitarian space. The air here smelled different—alive, green, the scent of soil and growing things.

Beckworth herself was small and precise, with close-cropped auburn hair and steady hands. She looked up from the drip irrigation system she was calibrating and gave Alejandra a measured nod.

"Commander Cruz. Welcome aboard."

"This is impressive," Alejandra said, and meant it. Maintaining a food garden on a deep-space vessel was notoriously difficult—the light cycles, the water recycling, the constant threat of contamination or system failure.

"It'll supplement the packaged rations by about fifteen percent," Beckworth said. "More importantly, it's a closed-loop atmospheric scrubber. These plants will handle a meaningful fraction of our CO2 processing. If the main scrubbers hiccup, this garden might be what keeps us breathing."

"You've done this before?"

"Three tours on the L5 greenhouses. Two years on the Atacama Station. I know how to keep things growing in places they shouldn't."

There was something else behind Beckworth's calm demeanor—a watchfulness, a quality of attention that went beyond a botanist's concern for her plants. Alejandra filed it away for later.

Diego Salvador was in the navigation bay, feet up on the console, running trajectory simulations on three screens simultaneously. He was lean and dark-haired, with quick eyes and the kind of restless energy that made small spaces feel even smaller. When Alejandra entered, he swung his feet down and grinned.

"Commander. I've been running the numbers on our intercept window."

"And?"

"And it's the most beautiful problem I've ever seen." He pulled up a holographic display of the solar system, with ʻAuʻau's trajectory marked in red—a long, curving line that sliced through the plane of the ecliptic and kept going, out into the dark. "She's moving fast. Forty-one klicks per second relative to the sun. Our intercept burns have to be precise to within about six seconds, or we blow past her and don't have the fuel to come back."

"Six seconds."

"I've worked with worse odds." He caught her expression. "Okay, I haven't. But the math is clean. The problem is solvable. It's just—" he searched for the word—"unforgiving."

"That's a good word for this whole mission."

"I was a professional gambler for nine years, Commander. Cards, orbital futures, commodity swaps. You know what I learned? The house always has an edge, but the edge isn't destiny. You can beat the edge if you play perfectly. No mistakes, no sentiment, no flinching."

"And if you make one mistake?"

"Then you lose everything. But that's true of life in general, isn't it?"

Alejandra studied him. There was something behind the grin—a seriousness, a depth of calculation that the casual manner was designed to hide. She'd known pilots like this. They were either the best or the worst, with nothing in between.

"Run the numbers again," she said. "I want to see every contingency."

"Already on it."

Conrad Slate was in the common room, drinking coffee from a sealed pouch with the practiced ease of someone who'd spent time in space but hadn't made it his home. He was perhaps fifty, with steel-gray hair cut short and a face that gave away nothing. His jumpsuit was standard issue, but it fit too well—tailored, Alejandra suspected, by someone who understood that appearance was a tool.

"Commander Cruz," he said, extending a hand. "Conrad Slate, Palladian Resource Consortium. I'm here to ensure our investment yields returns."

"Your investment is forty percent of the mission budget. My crew is one hundred percent of the risk."

"Which is why I'm here to help, not hinder. I have no desire to interfere with operations. I'm an observer. I document, I report, I stay out of the way."

"Good. Because on this ship, observers observe. They don't decide."

Slate smiled—a thin, professional expression that didn't reach his eyes. "Understood completely, Commander."

She didn't believe him. But she didn't need to believe him. She needed to watch him.

Later, alone in the commander's quarters—a space barely large enough to hold a sleeping bag, a fold-down desk, and a single personal item she hadn't yet chosen—Alejandra pulled up the mission timeline on her tablet and stared at it until the numbers blurred.

Seventeen days to launch. One hundred and forty-three days to intercept. Nineteen days on-site for anchoring, fragmentation, and redirect. Then the long fall home, riding the redirected fragment into Earth orbit like a cowboy on a comet.

Four percent fuel margin. Six crew. One ship that should have been scrapped a decade ago.

She closed her eyes and saw, as she always did in the dark, the faces of the four people she'd killed at Shackleton Station. Rodriguez. Tanaka. Oyelaran. Pietrov. They didn't accuse her. They just looked at her with the patient expectation of the dead, waiting to see if she'd learned anything from their dying.

"I'll bring them home," she whispered to the empty room. "All of them."

The room didn't answer. The ship hummed its old, tired heartbeat. And out beyond the orbit of Jupiter, a mountain of alien ice tumbled through the dark, keeping its appointment with a species that had no idea what it was about to find.
