Thomas Hartfield stood at the podium of MIT's Great Dome and looked out at three thousand young faces—faces that had never seen a real sky, that had never felt rain on their skin, that had never watched a sunset without the blue glare of the Prometheus Engines behind them.

"We are not fleeing our home," he said, and his voice carried through the auditorium like a bell. "We are taking our home with us."

The words had come to him the night before, written on a scrap of paper in his dormitory at 3 AM. He had not planned to say them. He had planned to talk about navigation vectors and engine calibration schedules and the orbital mechanics of the fifteenth periapsis pass. But something had shifted in him during those long, sleepless hours, and when he stood before these three thousand students—his classmates, his friends, his fellow travelers—he knew that numbers alone would not carry what needed to be carried.

Afterward, in the corridor outside the auditorium, a girl with dark eyes and a quick smile approached him. She held a tablet against her chest like a shield.

"That was beautiful," she said. "And slightly ridiculous. But beautiful."

"Islabelle Rothschild," she added, extending a hand. "Solar observatory, Greenland station. I analyze data that tells me whether our sun is going to explode in thirty years or fifty. So far, the data is undecided. I find this deeply unsatisfying."

Thomas shook her hand. Her grip was firm, her fingers cold—she had been up in the observatory, looking at the sun. "I'm Thomas Hartfield. Navigation engineering. And I find the data unsatisfying too, but for different reasons. I need to know where we're going. I don't care why."

Isabelle smiled. "You're an engineer. You want to build the bridge. I'm a scientist. I want to know if there's land on the other side."

"I suppose," Thomas said, "that between us, we might manage both."

They did not see each other again for six months. But Thomas thought of her—of her dark eyes, her quick smile, her defiant certainty that the data could be made to yield its secrets. And when the Joint Navigation Assignment came, and he found himself assigned to the Jupiter conjunction team with a co-analyst named I. Rothschild, he was not surprised. He was only glad.

The Jupiter operation lasted seventy-two hours. Seventy-two hours in the Ark Command, floating in the holographic blackness of the solar system model, watching the red spiral line of Earth's orbit approach the dark red disk of Jupiter like a thread approaching a needle's eye.

Thomas and Isabelle worked side by side at adjacent consoles, speaking in the shorthand of people who have stopped pretending they need to explain themselves to each other. Coffee went cold. Sleep became a rumor. The holographic sun cast their shadows against the walls like giants.

"At 0400, we burn the eastern array at twelve percent for forty-seven seconds," Isabelle said at some hour that might have been 2 AM or might have been 4 AM. Her eyes were red-rimmed but bright. "It gives us a velocity delta of point-zero-zero-three percent. Negligible in isolation. Cumulative over the operation, it's the difference between grazing Jupiter and falling into it."

Thomas nodded, running the numbers on his console. "Understood. I'll coordinate with the Asian array. They'll mirror the burn on their side."

"Mirroring won't be enough," Isabelle said. "They need to lead. By point-zero-zero-one percent. Or we miss."

Thomas looked at her. "You've already run the simulation."

"I've run it forty-seven times," she said. "The answer is always the same. They lead. We follow. And we pray that the engineers who built these engines knew what they were doing."

"They did," Thomas said. But he was not sure he believed it.

The burn began at 0400. Thomas watched the Asian array lights shift from green to amber to white as the engines tilted and fired. On the holographic display, Earth's orbit line trembled—just slightly, a quiver no thicker than a hair—and then held.

"Delta confirmed," Thomas said. "Point-zero-zero-one. They led."

Isabelle exhaled. "Good. Now we wait for Jupiter to decide whether to let us pass."

Jupiter decided in their favor. The great red eye of the Great Red Spot passed beneath them like the gaze of a sleeping god, and Earth slipped past the gas giant's gravity well with a velocity increase that pushed them toward escape velocity and, eventually, toward the four-point-three light-years of empty space that separated them from Proxima Centauri.

When the operation ended, when the last engine burn was confirmed and the navigation team collapsed into sleep, Thomas and Isabelle stood together in the observation gallery of the Ark Command and looked at the holographic solar system. Earth's orbit line had broken free of its spiral. It was now a green line—uncompleted, extending into the starfield beyond the model's boundary.

"We did it," Isabelle said quietly.

"We did part of it," Thomas corrected. "Fifteen orbits around the sun. Each one more dangerous than the last. Asteroid fields. Solar proximity. The long dark between apoapsis passes. We've cleared one hurdle. There are ninety-nine more."

"Then we'd better get started," Isabelle said.

They were married three weeks later, on the frozen surface of Lake Michigan. There were no guests, no ceremony, no priest or justice of the peace. Just Thomas and Isabelle standing on the ice in their sealed coats, with the blue glow of the Prometheus Engines behind them and the small pale sun hanging low in the sky like a coin tossed into a well.

An automated civil registrar—left over from the Pre-Sun era, still functioning because someone, somewhere, had maintained the backup generators—performed the ceremony in four sentences. Thomas and Isabelle signed the holographic contract. A green point appeared on a screen somewhere, confirming that they were, legally, husband and wife.

Isabelle laughed. It was a bright, unexpected sound on the frozen lake. "We're married. By a computer that was probably designed for a different century."

"By a computer that outlived its designers," Thomas corrected. "That's the point."

He did not know then that his father would be gone in two months. William Hartfield, Admiral of the Near-Earth Space Fleet, killed when a fragment of asteroid—shattered by an antimatter charge—slammed into his single-seat interceptor at one hundred kilometers per second. The cockpit vaporized instantly. The general who delivered the medal to Thomas said: "He felt nothing, Major. I can assure you of that."

Thomas accepted the medal. He went home. He opened a letter he had not known his father had written—unsent, unaddressed, stored in a secure file that had been triggered by William Hartfield's death.

It was three sentences long.

Thomas: If you are reading this, I am dead, and I regret that I have spent more time guarding this planet than living in it. I loved your mother. I loved you. And I spent my life protecting a world that will soon be left behind—not destroyed, but abandoned, carried away on engines of our own making. I am not sorry. Do not be sorry either. We are not fleeing. We are carrying our home.

Thomas read the letter once. Then he folded it and placed it in his coat pocket, next to his heart. He did not cry. He had not cried when the medal was handed to him, and he did not cry now. But something inside him shifted, the way Earth's orbit shifts— imperceptibly in the moment, cataclysmically in retrospect.

Twenty years later, Earth had passed Pluto's orbit. The Prometheus Engines ran at full power, five thousand years of fuel burning through the mountain ranges of Asia, turning stone into thrust, thrust into hope. Thomas stood in the navigation center—older now, his hair touched with gray, his hands less steady but his mind as sharp as ever—and wrote the first line of the Star Voyage log.

April 14, 2157. Earth has exited the Pluto orbit. We have left the solar system. Behind us: four billion and six hundred million years of history. Ahead: forty-three years of travel, then thirteen hundred years of滑行 at five-thousandths the speed of light, then five hundred years of deceleration, then—perhaps—Proxima's three golden suns rising over a green world.

Isabella stood beside him, her dark eyes reflecting the holographic starfield. She was still a scientist. He was still an engineer. Between them, they had built the bridge and confirmed there was land on the other side.

"We're just getting started," Thomas said.

And on the holographic display, the green line extended into the stars.
