Station Log — Day 1,847

Danny walked into Airlock 3 at 02:17 ship-time and did not press the open button. He stood there for seventeen minutes, staring at the hatch, and then he simply wasn't there.

I checked the cameras three times. The footage shows Danny entering the airlock, standing in the center of the chamber, and looking at the control panel. He did not touch it. He did not turn around. He did not scream. He just stood there, and then the footage glitched for approximately four seconds, and when it returned, the chamber was empty.

Lena says the cameras must have malfunctioned. I say I watched a man disappear from a locked room on a station orbiting a dead world, and I am no longer confident in the reliability of my own eyes.

We checked every cubic meter of the Rust Belt Station. Danny's quarters were undisturbed: his thermos still on the desk, his sleeping bag rolled at the foot of his bunk, his favorite book—a tattered paperback of Asimov's Foundation—left open on the pillow. But on the pillow, beneath the book, was a strip of paper torn from one of the station's maintenance logs. On it, in handwriting I did not recognize, someone had written:

DO NOT TRUST AUGUST.

The handwriting was Danny's. I am certain of it. But Danny is the one who disappeared.

Lena and I found the strip in the ventilation duct above Danny's bunk. The duct should have been inaccessible—it was sealed behind a maintenance panel that requires a torque wrench to open. I have the only wrench.

"What do you think it means?" Lena asked. Her voice was flat, the way it always was. Lena was a biologist, the kind of scientist who had seen too much death on the Moon and stopped expecting anything to survive.

"I think," I said, "that someone doesn't want us to trust August."

The station blueprints showed a sub-level beneath the medical bay that did not exist in the physical structure. I confirmed this three separate times: I measured the distance from the medical bay floor to the station hull, calculated the expected thickness of structural decking, and found a discrepancy of exactly three meters. Three meters of unaccounted space where, according to the blueprints, there should be a laboratory.

I found the entrance at 03:42, when the station's solar array had rotated away and the only light came from the emergency strips lining the corridor floor. The floor panel was slightly raised—a difference of perhaps two millimeters—but my hand found it the way a hand finds a loose floorboard in a haunted house.

Beneath the panel: a staircase.

The laboratory below was unlike anything I had seen on this station. The equipment was military-grade, the kind used in colonial military field hospitals. But the purpose was not surgical. It was cognitive. Memory editing arrays, neural interface rigs, pharmaceutical dispensers calibrated to deliver compounds I did not recognize.

On the central desk lay a file: TRAUMA RESET PROGRAM — PHASE II. The cover page bore the name of its director: Commander August, Lunar Command.

The program was simple and devastating in its logic. Colonial soldiers who returned from the Moon with severe PTSD were sent to this station for "treatment." They underwent memory editing procedures that selectively removed traumatic neural pathways. The process was painless. The results were immediate.

And permanent.

The file noted that post-treatment subjects exhibited a phenomenon the researchers called "hollowing"—a gradual erosion of personality following trauma removal. Without their pain, the subjects became... less. Not dead, not insane, just emptier. Like a building with its supports removed, it still stood, but it would not hold weight.

I pulled Danny's treatment file. Then Emily's. Then Peter's.

All three had volunteered. All three had signed consent forms. All three had undergone the full memory reset. And all three had been taken—either voluntarily or otherwise—to the laboratory below and processed a second time.

I accessed the communication log with Lunar Command. August's last message to the station read:

Phase II progress is optimal. All subjects responding as predicted. Continue monitoring. Subject THORNE-M is scheduled for Phase II initiation on next supply window.

Subject Thorne-M.

My name is Mark Thorne.

I opened my own medical file on the station terminal. What I found was not a record of voluntary service. It was an assignment order, signed by Commander August, dated two years ago:

Dr. Mark Thorne, former Colonial Army medical officer, assigned to Rust Belt Station Medical Facility for ongoing trauma observation and Phase I protocol compliance. Patient exhibits severe PTSD consistent with lunar dome breach incident. Recommendation: maintain isolation environment to prevent symptom resolution. Patient is to remain unaware of treatment program. Patient's investigative behavior, when it occurs, is to be permitted and monitored as it provides valuable data on trauma-driven cognition patterns.

I am not the station doctor. I am the experiment.

Every disappearance on this station was orchestrated by August from Lunar Command. The "investigation" I conducted was a pattern produced by my own trauma—a mind trying to make sense of its own dysfunction by projecting it onto external events.

Lena was not my colleague. She was August's monitor.

The station's door hissed open, and Lena stood in the doorway, her face expressionless in the corridor light.

"Mark," she said. "It's time."

"For what?"

"For the part you don't remember yet."

Outside the viewports, Mars hung in the void like a rusted coin, and the station drifted in its silent orbit around a world that no one wanted to live on anymore.
