The Silent Altitude

The docking bay’s air hit Janet like cold water - filtered, thin, and metallic, with the faint burn of sealant still drying along the outer seams. She stood with her boots on a grating that vibrated in slow pulses, as if the station itself was breathing through machinery. Behind her the transit tube’s mouth sat flush in the corridor wall, and where it had been open a heartbeat ago, a panel now sealed with a sound like a latch catching. The last light the tube had offered lingered in the air above the console: a ghost of a partial date fragment, blue-white and unsteady, refusing to finish resolving.

Janet pressed her palm to the console anyway, more by reflex than hope. The interface read her touch but not her identity - no welcoming chime, no familiar diagnostic glow. Instead, a thin strip of text crawled across the embedded display and vanished, replaced by a symbol that looked like an eye with a line through it. The station knew she was there. The station just didn’t know who she was.

“Station Vesper-9 docking access,” she muttered, tasting the words like they might unlock something. She could still feel the tube’s vibration in her bones, deeper than the bay’s hum, as if the corridor’s rhythm had followed her through the hatch and into her muscles. The corridor’s blue-white conduits had chased one another down the passage in that wrong kind of order, and the partial date fragment had hovered like a hook under her ribs. She wasn’t here to appreciate architecture. She was here to find the source of the broadcast that had spoken her name in static and shoved her into a future that already remembered her wrong.

The bay opened ahead into a wide concourse of docking cradles and maintenance walkways. Bulkheads curved in clean arcs, their surfaces scuffed by boots and service carts. Overhead, warning strips blinked in synchronized patterns; the soundscape was all steady fans and distant clanks, like the station was pretending to be calm. Farther in, an airlock bank rose in stacked segments, each gate framed by a biometric housing - an oval of glassy polymer with a thin halo of sensors, the kind that didn’t care how many times you’d survived doors.

Janet moved toward the nearest access lane. Her wristband - her real one, the one that should have been enough to prove she belonged - sat warm against her skin, but she didn’t trust it. The tube’s console had already hesitated, and the relay corridor had carried a rhythm that didn’t match anything in her mapping. The broadcast hadn’t sounded like a guide. It had sounded like pressure.

A small service robot trundled along the far wall, its wheels clicking over grates. It paused when Janet came into its field of view, then pivoted its camera module toward her with a chirp that was almost polite. Janet didn’t stop. She walked fast enough to keep her body from thinking too hard about the fact that she had no idea where the station’s internal clock would place her.

The biometric gate waited at the end of the lane, framed by two short handrails slick with condensation. A panel beneath the sensor read VESPER-9 AUTHORIZED PERSONNEL in blocky, utilitarian lettering. Janet lifted her wrist to the sensor halo.

The gate’s halo brightened.

For a second, nothing else happened. Janet watched the polymer eye, watching the way light rippled across it like a scan spreading under skin. She felt the station’s attention settle on her with the same weight as the relay’s corridor - patient, exact, and cold.

Then the halo flared red.

A tone sounded - short, sharp, unmistakably corrective. The airlock housing clicked as if preparing to engage. Janet’s wristband vibrated once, then went dead, its edge going slick as though the station had squeezed its power away through the interface.

“No,” she said, too quietly for the bay to hear and too loud for her own comfort.

The panel beneath the sensor displayed a single line of text in hard white characters: BIOMETRIC MISMATCH. ACCESS DENIED.

Janet pulled her wrist back, heart working too fast. “That’s not possible,” she said, and immediately hated how thin it sounded. She’d survived relays and transit tubes and corridors that turned into something else. She’d forced a hatch once by sheer refusal. Denied access shouldn’t have been able to stop her. Not here. Not now.

The gate’s oval sensor rotated a fraction, recalibrating. A second message blinked into existence, slower this time, as if the station had decided to be thorough.

EXPECTED PROFILE: JANET MARROW - AUTHORIZED.

Janet stared at the words until her vision blurred at the edges. Her name, her surname - correct. The station had her identity on record.

So why did the gate reject her?

Her mind reached backward, searching for the moment she’d become “wrong.” In the tube, the straps had released with a click. The padding had loosened. She’d stepped out into a corridor where the floor hadn’t existed a heartbeat ago....
