The first sky Yuki Tanabe ever saw was on fire.
Not literally, she knew that, the rational part of her brain filing it away even as the rest of her stood paralyzed at the observation deck viewport. Ross 128 b's sun hung low and fat and red on the horizon, a bloated ember four times the diameter of the Sol she'd only seen in textbooks. It painted the clouds in streaks of vermilion and rust, and the light fell across the land below in a way that looked like the world was bleeding out.
"Jesus," whispered Sergeant Maya Escobar, standing beside her. "That's a sunset."
"No," Yuki said. "That's permanent."
She'd studied it her whole life, all forty five years of it, every one spent inside the hull of the Shackleton. A tidally locked planet. One face forever aimed at its star, one face forever turned away. No sunrise, no sunset, just an eternal band of twilight ringing the planet like a belt, the terminator line where day met night and, according to ninety years of carefully maintained climate models, where two thousand human beings could build a life.
Yuki pressed her palm flat against the viewport. The glass was cold. Outside, the planet waited.
She had not expected this feeling. She'd run the simulations in her head a thousand times, prepared herself for every scenario from jubilation to technical failure, had practiced her address to the colony, the measured, calm, competent voice they needed from their governor. What she had not prepared for was the sheer disorienting scale of it. The Shackleton was 340 meters long. The largest open space inside it was the mess hall on B deck, which could hold maybe 200 people if they stood. Outside that viewport was a horizon. A sky that curved. Weather. Distance that didn't terminate in a bulkhead. Her depth perception, calibrated to corridors and compartments, stumbled over the information like a person finding stairs in the dark.
"Captain." The voice came from behind her. Dr. Ranjit Patel, the colony's chief climatologist, a thin man with careful hands and the perpetual frown of someone who trusted numbers more than people. He was holding a tablet, and he was not smiling. Ranjit never smiled during descent prep, but his particular expression now had a quality Yuki didn't like. It was the expression of a man whose numbers had started whispering something ugly.
"Wind readings from the probes," he said.
She took the tablet. The data columns meant nothing to most people, but Yuki had made herself fluent in atmospheric science over the past decade the way she'd made herself fluent in agronomy, civil engineering, water reclamation, conflict mediation, and seventeen other disciplines she'd never planned on needing. You didn't plan a career as a planetary governor. You inherited it, the way you inherited your grandmother's bad knees and your father's silence. Her father, Daisuke, had been the Shackleton's third navigation officer. Her mother, Akiko, a hydroponics technician. Neither of them had signed up to be the parents of the person who'd be standing at this window when the ship finally arrived. Nobody signed up for anything aboard the Shackleton. You were born into it, and you made yourself useful, and if you were unlucky enough to be competent and calm in a crisis, people started looking at you the way they looked at Yuki. The way a congregation looks at a priest. Not because they think you have answers, but because they need someone to stand at the front.
The numbers were high.
"These are surface readings?"
"Confirmed by three separate probes, all in the target landing zone." Ranjit tapped the screen. "Wind speeds are averaging 140 kilometers per hour. Gusting higher."
Yuki looked at him. "The models predicted 40 to 60."
"Yes."
"So the models are wrong."
Ranjit's frown deepened, which she hadn't thought possible. "The models are... incomplete. I need surface composition data to understand why. But Captain, 140 sustained is..."
"I know what it is." She handed the tablet back. 140 kph was a Category 1 hurricane on Earth, and Earth was a planet none of them had ever visited, a place that existed only as a data archive and a vague ancestral guilt. "What about the backup sites?"
"All along the terminator. All showing similar readings." He paused. "The wind is the terminator, Captain. The thermal gradient between the dayside and nightside drives it. We always knew that. We just didn't know it would be this... enthusiastic."
"Enthusiastic," Yuki repeated. She almost laughed. Behind them, the observation deck was filling with people, fourth generation colonists, every one of them born in recycled air, pressing against the glass to see a sky, a horizon, open space that didn't end in a bulkhead. Some of them were crying. A little girl had her face smashed against the viewport with both hands spread wide, mouth open, making a sound that wasn't quite a word. An elderly man, Gheorghe Ionescu, stood with his hands clasped behind his back and his chin lifted and his eyes wet, looking at the planet with an expression Yuki recognized from old photographs of immigrants arriving at port cities: hope and terror in equal measure, and underneath both, the exhaustion of having traveled too far to turn back.
They'd been in transit for ninety years. Ninety years in a ship that was never meant to be permanent, that was coming apart at the seams (literally, in some sections, the hull patches held together with polymer adhesive and prayer). The hydroponics bays were failing. The water recyclers were down to 71% efficiency. The primary reactor had been on reduced output since year sixty seven, and the backup had a containment fault that Chen Wei, the chief engineer, described as "manageable" in his reports and "terrifying" after his third drink. They had maybe eighteen months of margin left, and that was the optimistic estimate.
They couldn't turn around. There was nothing to turn around to.
"We land as planned," Yuki said. "Site Alpha. We deal with the wind."
Ranjit opened his mouth, closed it, opened it again. "Captain..."
"We land as planned, Ranjit. And then you figure out why the wind wants to kill us."
They came down in the landers, eight of them, cargo shuttles with bulging bellies that had spent nine decades locked in the Shackleton's belly like wasps in a nest. Each one carried 250 colonists, plus equipment, plus seeds, plus the compressed and catalogued remnants of a civilization that had sent them here because it was running out of room and running out of time.
Yuki rode Lander One. She sat in the command chair with her harness cinched tight and watched the altimeter unwind and felt gravity (real gravity, planetary gravity, not the spin simulated variety) settle into her bones like concrete. She weighed more here. Ross 128 b had 1.3 times Earth's surface gravity, and she felt every fraction of that surplus in her knees, her spine, the muscles of her neck. She was forty five years old, and she had never carried this much weight in her life.
The atmosphere hit them at 80 kilometers altitude. The lander shuddered, then shook, then began to scream. Not figuratively. The friction of atmospheric entry against the heat shield produced a sound that propagated through the hull, a high, sustained wail that rose and fell as the turbulence shifted. The vibration rattled the storage bins above the passenger seats and set the overhead lights swinging, throwing shadows that lurched across the cabin. Behind Yuki, a child started crying. An adult started praying. She could hear both. She could also hear Park, who was strapped into the copilot seat monitoring the approach trajectory, calling out altitude and velocity in a voice so steady it sounded automated. Yuki stared at the altimeter and kept her face empty, because two hundred and fifty people were watching, and a governor's face was the only instrument they could read.
The atmosphere was thicker than Earth's. They'd known that from spectroscopy (at least the spectroscopy had gotten the atmospheric depth approximately right), and the lander's flight profile accounted for the denser air, but knowing a fact and feeling it were different categories of understanding. The lander decelerated hard, the air braking more aggressively than any simulation had prepared them for, and the G forces pressed Yuki into her seat. She tasted copper. Her vision grayed at the edges.
The landing was rough. Not dangerous (the pilots were good, trained on simulators that suddenly seemed laughably inadequate) but rough. The wind caught them at 3,000 meters and didn't let go. Cold dense air from the nightside was pouring toward the dayside at the surface, colliding with hot air boiling up from below, and the shear hit the lander broadside like a truck. Yuki heard metal groan. She heard someone behind her throw up. The lander yawed, corrected, yawed again, dropped fifty meters in a downdraft that left her stomach somewhere above her head, and then the landing struts hit dirt and the whole vehicle rang like a bell.
Silence. Then the sound of breathing. Two hundred and fifty people remembering how.
"Lander One, surface contact," Yuki said into the comm. Her voice was steady. She'd practiced that voice for twenty years. "All landers, report status."
They'd all made it. Eight landers, two thousand people, alive on the surface of an alien world.
Yuki unstrapped and stood, and the gravity reminded her it was there. She walked to the main hatch. The status panel showed external conditions: temperature 18°C, wind 156 kph gusting variable, atmospheric pressure 1.08 bar, oxygen content 19.2%. Breathable. Barely.
She hit the release.
The hatch opened, and the world came in.
The wind hit her first, not the number on a screen but the physical fact of it, a fist of air that staggered her back a step. It shifted constantly, cold gusts from the nightside one moment, warm turbulent bursts from dayside convection the next, and it carried a smell she had no reference for. Mineral. Dusty. Alive, somehow, in a way she couldn't name. Behind the wind came the light: that red, red light, the sun huge and red on the horizon like it had been nailed there. The sky above was a gradient, burnt orange near the sun, deepening through purple to black on the nightside, and in that black she could see stars. Stars she'd navigated by, seen through instruments, computed trajectories around. Now they were just lights in a sky, and the sky was real, and it went up forever.
She stepped onto the surface of Ross 128 b.
The ground was hard packed regolith, rust colored, streaked with darker minerals. It crunched under her boots. The wind pushed at her constantly, a pressure she had to lean into, and it tugged at her hair and her clothes and the skin of her face. She squinted against it. Her eyes watered.
"First human footprint on an exoplanet," Escobar said, appearing beside her, shouting over the wind. The security chief had her hand on the frame of the hatch, steadying herself. Her dark hair whipped sideways. "You want to say something historic?"
"Yeah," Yuki shouted back. "Why is it so goddamn windy?"
