The Manhole Cover

The targeting reticle flickered across my primary display, locked onto a tiny, high-density radar signature tumbling through the dark.

We had first logged the object three years ago—an absolute anomaly drifting through the void. At first, astrometrics assumed it was just a stray metallic meteorite. But nature doesn’t forge perfectly circular, hyper-dense iron plates with uniform thickness. Someone had built this. It was our first tangible proof of an intelligent civilization beyond our world.

My mission was straightforward: match its erratic velocity, deploy the capture arms, and bring it into the hold for analysis. In practice, it was a kinetic nightmare.

“Velocity matched,” I muttered, hands gripping the thruster controls as I adjusted our alignment. “Range: forty meters. Target is tumbling at seventy revolutions per minute.”

The object glinted in our navigation floodlights. Up close, it was battered, pitted by cosmic dust, and heavily scorched on one side—cooked by an incredible flash of heat before being hurled into the void.

“Extending capture limbs.”

The ship groaned as the mechanical arms reached into the vacuum. One bad angle and the spinning slab of dense metal would shear through our hull. I waited for the apex of its rotation… three, two, one—engage.

The magnetic dampeners slammed shut with a heavy shudder that rattled through my seat. Force fields caught the object, violently absorbing its momentum until the tumbling stopped.

Target secured.

I vented a long breath and initiated the pressurized airlock cycle.

Leaving the flight deck, I moved down to the observation deck overlooking the primary bay. The floodlights hummed, washing over our prize.

It was surprisingly crude. A single, heavy disc of forged metal, rough-edged, with one side melted nearly smooth and the other showing severe structural warping. It didn’t look like a deep-space probe or a communication device. It looked like a cap. A lid.

I activated the diagnostic suite to analyze the artifact’s history.

The sensors flashed back immediate, alarming results:

• Structural State: Massive kinetic shockwave stress and extreme atmospheric friction scarring.
• Isotopic Profile: Saturated with intense, hyper-concentrated nuclear radiation residue.

The realization sent a chill down my spine. This hatch hadn’t been gently launched into space by a rocket engine. It had been violently blasted clear out of a planet’s gravity well by an incomprehensible, surface-level nuclear explosion.

I zoomed the optical camera onto the rim of the disc, where a series of raised, blocky shapes were stamped into the metal alloy. I stared at them, but they offered no context. They were completely alien—just an arbitrary arrangement of straight lines, right angles, and curves:

U.S. AIR FORCE

I ran the markings through our translation matrix, but it returned zero matches. No linguistic logic, no recognized mathematical symbols. Just meaningless geometric etchings stamped onto a chunk of radioactive iron.

I stepped back from the viewplate, looking out past the containment bay at the silent, empty cosmos.

We were not alone. And somewhere out there in the dark, a unknown species had detonated a nuclear weapon so powerful it accidentally fired a piece of their own world into the stars.
