The Signal from Station Nine

The Quiet Station

Station Nine had been silent for three weeks when Reza's repair shuttle docked with a soft, shuddering clunk.

He was thirteen, the youngest engineering apprentice the orbital service crew had ever sent out alone — though alone wasn't quite true. His supervisor, Captain Lin, watched from the home station through a video link that crackled with the distance between them.

"Remember," Lin's voice said in his earpiece, "you're there to check the life-support systems and come home. Nothing fancy. In and out."

"In and out," Reza repeated. He pushed off from the airlock and floated into the long central corridor of Station Nine.

The station was huge — a wheel of metal turning slowly against the black sky, built to house twelve scientists. But the lights were dim, running on backup power, and the air smelled faintly of dust and cold metal. The crew had been evacuated after a power failure, all twelve of them accounted for and safely back on Earth.

So the station should have been empty.

That was why the signal made no sense.

A Pattern in the Noise

Reza heard it the moment he plugged his tablet into the station's main computer. Beneath the hum of the failing systems, there was a sound: a faint, rhythmic tick... tick-tick... tick.

He almost ignored it. Old stations were full of strange noises — pipes groaning, metal cooling, fans struggling on low power. But something about this sound was different. It was too regular.

He started a timer.

The pattern repeated. Then it repeated again. Reza watched the seconds count up and felt the small hairs on his arms rise.

Every forty-seven seconds. Exactly. Tick... tick-tick... tick. A pause. Then again.

"Captain Lin," he said into his earpiece, "I've got a repeating signal on the station. Same pattern, every forty-seven seconds."

There was a long delay before Lin answered — the distance again. "Probably a stuck relay, Reza. Electronics fault. Log it and move on to life support."

A stuck relay. That was the easy answer, and Reza wanted to believe it. But he'd repaired a hundred stuck relays, and none of them had ever kept perfect time. Random faults were random. This was a clock. This was a drumbeat.

This was a message.

Asking Better Questions

Reza had learned one thing from Captain Lin above all else: when something doesn't fit, don't argue with it. Ask it better questions.

So instead of guessing, he traced the signal. He floated from junction to junction along the corridor, watching the strength of the pattern climb on his tablet. When it grew louder, he went that way. When it faded, he turned back. It was like a game of warmer-and-colder played across an entire space station.

The trail led him away from the engine rooms, away from the computer core, and toward a part of the station marked on his map in faded letters: GREENHOUSE MODULE — SEALED.

The greenhouse. Where the scientists had grown food and tested plants for long voyages. According to his records, it had been sealed off during the evacuation when its door mechanism jammed.

Reza pressed his ear to the heavy door. The sound came through clearer now, vibrating in the metal itself. Not from a wire. Not from a relay.

Someone was knocking.

The Voice on the Other Side

His heart slammed. He forced himself to breathe slowly, the way he'd been trained — panic makes mistakes, and mistakes in space are dangerous.

He keyed his tablet to the door's emergency channel. "Hello? This is Reza Haddad, repair crew. Is someone in there?"

For three long seconds, nothing.

Then a voice, thin and dry and shaking with relief, crackled back. "Oh, thank the stars. Yes. Yes. My name is Dr. Amara Okafor. I'm a botanist. I've been trapped in here for twenty-three days."

Reza gripped a handhold to steady himself. "The crew log says everyone was evacuated. All twelve."

"They miscounted," she said. "I was below the floor panels checking the root tanks when the alarm went. The door jammed shut behind me. By the time I climbed out, the shuttle was gone, and the radio in here was dead." A weak laugh. "But the greenhouse has its own air and water. The plants kept me breathing. The plants kept me alive."

"The signal," Reza said. "The tapping. That was you?"

"Every forty-seven seconds, on the hour, for twenty-three days," she said. "It's the only number I could keep counting in the dark without losing track. I knew someone would come back eventually. I just had to make sure that when they did, they'd hear me."

The Stuck Door

Reza could have called for backup and waited. But Dr. Okafor's voice told him she didn't have many more days of waiting in her.

He examined the door mechanism. The jam wasn't complicated — a single warped bolt had wedged the locking arm. The kind of thing that looked terrifying until you understood it, and simple once you did.

"Dr. Okafor," he said, "I need you to move to the far side of the module. I'm going to release the lock manually, and there'll be a pressure shift."

"I trust you," she said. "You found me. Nobody else even looked."

It took twenty minutes, three tools, and a great deal of careful, patient force. When the locking arm finally gave way, the door slid open with a long sigh of equalizing air — and there, pale and thin but standing tall among rows of green, impossible, living plants, was Dr. Amara Okafor.

She looked at Reza, then at the garden that had saved her, and her eyes shone.

"You listened," she said simply. "Everyone else heard noise. You listened."

Home

On the long ride back, Captain Lin's voice came through the link, gruff and a little amazed. "In and out, I said. You came back with a missing scientist."

Reza watched Dr. Okafor sleeping in the seat beside him, finally safe, the recordings of her twenty-three days of patient tapping saved on his tablet.

"The easy answer was a stuck relay," he said. "But the easy answer was wrong. I just had to ask the signal a better question."

He had learned something out there in the silence — something no manual had taught him. A mystery is not a wall. It's a door with a stuck bolt. You don't smash it. You study it, you stay calm, and you listen until it tells you how to open it.

Far below, Earth turned blue and bright, and Station Nine grew small behind them, quiet at last.
