Redundant Cycle
- 03:12 ZULU. Elias stepped through the airlock, his magnetic boots clanking against the steel decking of Relay Station 44-B. The air was thin, tasting of ozone and recycled silica. He checked the oxygen sensor on his wrist: 18.2 percent and falling.
He moved toward the center of the module. The station was meant to be automated, a hollow shell transmitting packets of data from the Jovian colonies back to the inner rim. It shouldn’t have had a life-support system active, let alone a pod chamber warmed to thirty-seven degrees Celsius.
He found the occupant in Pod 04. The glass was frosted, but the internal heater hummed with a soft, rhythmic vibration. Inside, a man lay curled on his side, his fingers white-knuckled around a ceramic mug. A dark, jagged crescent of coffee stain marred the rim. The ceramic was vintage, an object of high mass and zero utility in a vacuum-sealed environment.
Elias tapped the console. The diagnostic printout slithered from the slot, a narrow ribbon of thermal paper. He scanned it: Personnel Manifest: Nil. Current Occupancy: 1. Unauthorized presence confirmed.
- The corridor light flickered. A soft, wet sound echoed from the vents—the station’s ventilation system cycling through a backlog of static. Then, the intercom hummed to life.
"The air was thin, tasting of ozone and recycled silica," the voice said. It was Elias’s voice, transposed into a flat, synthetic register. "He checked the oxygen sensor on his wrist: 18.2 percent and falling."
Elias froze. He gripped his utility tool, his knuckles aching. He had not spoken aloud since boarding. The station was recording him and playing the audio back with a three-second delay. It was a diagnostic loop, a software error designed to verify audio fidelity in empty rooms.
He walked toward the life-support manifold at the end of the corridor. The technician in Pod 04 shifted. His eyes remained closed, but his breathing accelerated, syncing with the playback of Elias’s voice.
- The diagnostic printout continued to feed from the slot, trailing onto the floor like a pale serpent. Elias picked it up. Further down the list, under Unauthorized Presence, a sub-line appeared: Replacement Technician: Serial #773-Alpha. Status: Active. Directive: Redundancy verification.
He stopped. A redundancy wasn't a failure; it was a backup protocol. If the station thought Elias was a malfunction, it would have already vented the chamber. If it thought the man in the pod was the primary, then Elias was the rogue variable.
"He walked toward the life-support manifold at the end of the corridor," the intercom droned. The voice sounded tired, human, and entirely detached.
Elias reached the manifold. The pressure was dropping faster now: 16.8 percent. The station was starving the air to prioritize the transmit signal for the next packet burst. In four minutes, the station would beam its internal logs to the hub. If the log included an unauthorized technician, the hub would trigger an automated purge of the station, incinerating everything within the hull to prevent data corruption.
- The man in Pod 04 sat up. The glass slid open with a hiss of decompressing seals. He looked at Elias, then down at the ceramic mug.
"You're late," the man said.
Elias kept his tool aimed at the man’s chest. "The station thinks there’s only one of us. Which one?"
The man took a sip from the mug, despite there being nothing in it. "It doesn't matter what the machine thinks. It only matters what it transmits. If you seal the module, the sensor detects a vacuum. It assumes the unauthorized element has been purged."
"And you?" Elias asked.
"I'm a placeholder. I was never scheduled to exist, so I don't technically occupy space. You, however, have a payroll ID."
Elias looked at his own reflection in the corridor mirror—a dark silhouette against the sterile, white-tiled wall. The intercom repeated: "He looked at Elias, then down at the ceramic mug."
- The choice was a mechanical calculation. If he left the man in the pod, the station would count two biological entities at the moment of transmission. The purge protocol would initiate. If he sealed the module, he trapped the other man in a vacuum while he exited. But if the station’s diagnostic identified him as the redundant file, he might be the one the machine chose to vent.
"The choice was a mechanical calculation," the intercom said, repeating Elias’s internal process.
Elias moved to the locking mechanism of the pod chamber. The man did not fight him. He merely sat, cradling the mug, watching the red LED indicator on the bulkhead count down to the broadcast. 00:45 seconds remained.
"Is it warm?" the man asked, gesturing to the pod.
"It’s calibrated," Elias replied.
"That’s usually the same thing."
Elias gripped the heavy manual override lever. He thought about the hub, the bureaucratic machine that would receive the report. They didn't care about the personnel, only the integrity of the data stream. If the stream remained clean, the hub would never know a technician had spent an hour being interrogated by his own recorded voice.
- 03:26 ZULU. The station shivered. A deep, metallic groan resonated through the floorplates as the long-range transmitter initialized.
Elias didn't look back at the pod. He hit the manual seal. The locks engaged with a series of sharp, pneumatic cracks. He sprinted for the airlock, his breath ragged. The intercom was still playing, but the voice had begun to overlap with itself, creating a discordant, layered chorus of his own previous sentences.
He cycled the airlock and stepped out into the crushing, silent gravity of the moon’s orbit. He waited.
Ten seconds later, the station flared—a sudden, blinding pulse of white light as the transmitter triggered the final transmission burst. There was no explosion, only the systematic dumping of internal heat into the void.
Elias checked his wrist. The oxygen sensor steadied at 21 percent. He looked at the station. It was back to being a silent, drifting monument of steel and wires.
On the hull, a small smear of ceramic dust settled against the airlock seal, carried out by the venting atmosphere. He wiped it away with his glove. It was just a particle of clay.
