The Sling and the Stone

In Short

This tense science-fiction short story follows a Russian scientist coerced into helping his government turn a five-mile-wide nickel-iron moonlet into a weapon of mass destruction. By manipulating the trajectory of this "second moon," the military leadership plans to force global submission through a calculated act of terror. The narrative explores themes of scientific ethics, the crushing weight of totalitarianism, and the individual's search for agency in the face of inevitable destruction. It remains a stark, chilling meditation on the intersection of fragile human ego and catastrophic military power.

The Story

The story begins with the silent construction of a secret Soviet space station. Four men, including the hardened commander Krylov, establish a base of operations, but their ambition extends far beyond simple surveillance. They soon capture Pyotr Diavilev, a disillusioned scientist, from his home in the dead of night. Despite his fear and his long history of submission to the state, Diavilev is flown to the station. He is initially struck by awe at the technological achievement, but his wonder quickly curdles into horror when he discovers the station’s true purpose.

Krylov introduces Diavilev to a "second moon"—a dark, five-mile-wide hunk of nickel-iron captured by Earth’s gravity. The military plan is to use a series of hydrogen bomb explosions to slow the moonlet’s orbit, turning it into a guided kinetic projectile capable of obliterating a target on Earth. Krylov intends to frame this devastation as an "act of God," a cataclysmic omen that will force the capitalist world to its knees. Diavilev, realizing that he is trapped and that his captors are driven by a mixture of messianic delusion and cold, calculated cruelty, initially accepts his fate. However, as the final countdown nears, he finds a sliver of leverage.

As the final bomb is prepared, Diavilev tricks Krylov into boarding the moonlet with him under the guise of scientific discovery. Once on the surface, Diavilev strands his captor, forcing him to remain on the projectile as it begins its final, fatal descent into Earth's atmosphere. Before the end, Diavilev reveals his final act of sabotage: he had lied about the mass and speed of the moonlet. Instead of striking the United States, the projectile is locked into a trajectory that will devastate the Russian homeland. Krylov, realizing that his own hubris and the scientist's deception have doomed him, descends into hysterics. The story concludes with the fiery destruction of the moonlet, as Diavilev and his captor are incinerated upon reentry, their final moments marked by the scientist’s cold satisfaction in orchestrating a "poetic" and irreversible end to the madness.

How It Unfolds

The station is built Four men arrive in space to assemble a doughnut-shaped station. They work in silence, attaching ribs and wires to the structure while the rocket that brought them departs, leaving them isolated in the void.

The prisoner is taken Pyotr Diavilev is abruptly seized by army men in the middle of the night. He is shuttled through a series of dark transit points, eventually finding himself aboard a mysterious vessel hurtling into space.

The mission is revealed Once aboard the station, Krylov explains the power they now wield over the world. He reveals the existence of the moonlet and demands that Diavilev calculate the trajectory needed to turn the rock into a weapon.

The moonlet is prepared Diavilev performs his calculations while the military team uses hydrogen bombs to nudge the moonlet out of its stable orbit. Krylov gloats about the psychological impact of the impending strike, calling it the "hand of God."

The final deception Diavilev manages to lure Krylov onto the surface of the falling moonlet. He reveals that the calculations were rigged, ensuring that the target is not America, but Russia itself.

The descent begins As the moonlet enters the atmosphere, the radio crackles with Krylov's frantic, incoherent rage. Diavilev meets his end with a sense of grim peace, knowing the weapon will destroy its creators.

The People

Pyotr Diavilev is the story’s weary, intellectual protagonist. A man who has spent a lifetime "yessing and bowing" to survive the purges, he is initially defined by his profound fatalism. His desire for peace and his awe of the universe eventually collide with his moral conscience, transforming him from a passive victim into a vengeful architect of the station's destruction.

Krylov serves as the embodiment of state-sanctioned insanity. A "dark, black-browed man," he possesses no scientific expertise but harbors a dangerous, grandiose ambition. He is the one who views the moonlet as his personal "hand of God," a tool to reshape history through terror. His ego and absolute contempt for "intellectuals" like Diavilev ultimately prove to be his undoing, as he assumes that no scientist would ever dare to lie to him.

The secondary crew members—Stolyakhin and the others—function as an extension of Krylov’s will. They are indifferent, brutal men who treat the impending genocide as a grand, amusing game. They contrast sharply with Diavilev’s internal struggle, highlighting the dehumanizing atmosphere of the station where scientific rigor is subordinated to the caprice of the "army men."

In Its Own Voice

Describing the chilling reality of the station's purpose, the narrator notes:

Atomic missiles launched from this base may be guided exactly to any point on the surface of the Earth that we select, yet the station itself represents so small and distinct a target as to be virtually invulnerable.

As Diavilev confronts the reality of his situation, he reflects on his own compliance:

I will say whatever they want me to say, I will not resist in the least.

Finally, upon witnessing the moonlet for the first time, Diavilev captures the terrifying scale of the object:

Like a stone, Diavilev thought from the sling of God.

What It's Really About

The central theme of the story is the danger of placing absolute power in the hands of those who equate technological dominance with moral authority. The "sling" of the title represents the misuse of science—the way humanity takes the tools of creation and turns them into instruments of ruin. There is an argument here about the fragility of civilization when governed by individuals who view mass death as a "poetic" or necessary political tool. Beneath the plot lies a deep-seated anxiety about the Cold War arms race and the terrifying ease with which a "small" scientific error or a single act of defiance can cascade into total destruction. It asks whether a man who has lost his soul to survival can ever truly reclaim it.

Why Read It Today

Readers who appreciate sharp, dark political thrillers from the mid-20th century will find much to admire here. The writing is precise and economical, stripping away unnecessary exposition to focus on the suffocating, weightless atmosphere of the space station. You will feel the claustrophobia of the pressurized room and the biting, lonely cold of space that eventually offers Diavilev his only form of comfort.

The story is a product of its time, reflecting the era’s specific anxieties about Soviet expansion and the dawn of the space age. However, its depiction of a man trapped between a corrupt, unthinking bureaucracy and his own moral decay remains startlingly relevant. The pacing is rapid, and the ending is uncompromising, trading typical science-fiction heroics for a much more cynical, visceral conclusion. Those sensitive to the casual, dehumanizing language used by the military characters may find some passages difficult, but this serves to reinforce the story’s critique of the "insanity" Diavilev is trying to escape. It is a short, sharp punch of a story that lingers, leaving the reader to contemplate the thin line between the "hand of God" and the catastrophic failure of human judgment.
