Introducing: Historical Notes
In this episode I debut a new micro-feature: Historical Notes — a kind of field journal where I track odd connections, pulpy precedents, and little research threads I want to return to later. Think of them as digital slips of paper on the edge of a busy desk: half ideas, future essays, maybe even the seeds of a book.

In this explosive Episode #87 of The Rocketeer, I’m revisiting Stanton A. Coblentz’s “The Sidereal Time-Bomb,” a 1943 space-disaster tale that never quite stuck the landing. Once a familiar name in the pulps, Coblentz delivers a story filled with outdated “space cars,” distant narration, and convenient cosmic saves—but buried inside is one irresistible idea: an alien munitions asteroid drifting into our Solar System. I unpack how this older narrative style clashed with wartime science fiction trends, what fans of the day thought, and why the story’s concept feels strangely timely now. As today’s real comet 3i/Atlas continues behaving in unexpected ways, the question arises: what if a forgotten pulp misfire accidentally mirrors a modern mystery in the sky?
The Sidereal Time-Bomb appeared in Startling Stories, Winter 1943 issue. It has never been reprinted—probably for good reason. While Coblentz was a respected Golden Age name, this particular tale shows its age: old-fashioned tech, distant narration, a too-convenient solution to planetary doom, and a final act that even fans of the era found questionable.
Yet the central image fascinates: an enormous alien weapons cache drifting into our system, threatening everything in its path. It’s the one element that still crackles with energy—and the one that makes the story strangely relevant today.
