Here’s a dark ambient story prompt featuring the RT-64 Radio Telescope (Radioastronomicheskaya)—a desolate, atmospheric piece suited for a short film, game intro, or narrative worldbuilding.

Deep in the forests of Crimea, the towering skeleton of the RT-64 Radio Telescope, once a jewel of Soviet-era astronomy, looms over decaying infrastructure and forest-choked access roads. Now known only as Radioastronomicheskaya, it’s been inactive for decades—its cold dish slowly rusting under storm-gray skies.

The year is 2025. A low-level technician named Mira Volkov, working for a private atmospheric monitoring firm, is sent to inspect an old Soviet relay station near the ruins of the RT-64 site. She’s given no explanation—just a file with strange RF interference data, a key to the main gate, and a warning not to engage the main dish.

The Kalyazin RT-64 radio telescope, constructed in the USSR, was originally designed for communication with robotic missions to Venus and Mars, with ambitions for manned missions to these planets. Although the manned

As she arrives, strange anomalies begin. GPS signals flicker. The woods grow unnaturally still. A low hum—barely audible—resonates in her chest when she passes beneath the dish.

In the abandoned control building, dusty terminals flicker to life as though expecting her. One by one, archived data logs begin to decrypt—revealing that the telescope had been receiving a persistent narrow-band transmission on a frequency that shouldn’t exist.

It started the night the Soviet Union collapsed.

And it’s still broadcasting.

The signal is not human. It’s rhythmic. Pulsing. Some believe it’s a beacon. Others, a warning.

Outside, the dish slowly begins to rotate on its own.

Dark Ambient Elements You Can Use:

  • Soundscape: Insect drone, cold wind over steel, distant thunder, feedback loops, fragmented Russian radio chatter.

  • Visuals: Fog-drenched pine trees, red warning lights flickering in mist, rusted terminals glowing green, notebooks filled with non-Euclidean diagrams.

  • Lore Clues: Soviet-era notes referencing “Object K-17,” an anomalous frequency map, an operator’s last log entry ending with: “It’s listening now.”

  • Finale Option: Mira either transmits a reply—or becomes the new source of the signal.
