B-12's Moon Glow

In Short

On the desolate Martian moon of Phobos, a banished, rust-pitted robot named B-12 distills a high-octane, illegal elixir called Moon Glow to help his fellow discarded metal people endure their endless exile. When a visiting Earth senator arrives with a sleek modern robot to survey the junkyard moon for wholesale liquidation, B-12 uncovers a sinister plot to melt down all the island's inhabitants. Using his illicit brew to incapacitate his high-tech rival and uncovering a compromising political secret, B-12 leverages blackmail to save his people from destruction.

The Story

B-12, an obsolescent General Purpose metal person living on the junkyard moon of Phobos, operates a hidden distillery producing "Moon Glow," an illegal stimulant that gives aging robots new life. While sneaking through Argon City, B-12 startles a visitor from Earth, earning a hurled alarm clock to the headpiece. Returning to his associate Benny, B-12 learns that important visitors have arrived from Earth, including Senator Simon F. Langley, a younger woman traveling with him, and a sleek modern robot named MS-33 who views older models with intense disdain.

Jon Rogeson, a friendly Terran peace officer, enlists B-12 to guide the senator's party through the Dumps—a vast vista of rusted spacecraft and abandoned machinery. During these surveys, MS-33 treats B-12 with open contempt, while Langley displays a gleeful interest in the scrap metal. B-12 senses hazard and determines to uncover their true purpose. When Jon photographs Langley and his companion, the senator flies into a rage and demands the plate, hinting darkly that Jon's job and the settlement will soon cease to exist.

Determined to find answers, B-12 breaks into the visitors' quarters and discovers a photograph revealing that the woman traveling with Langley is not his wife. Shortly afterward, MS-33 tracks B-12 to his hidden distillery, intending to arrest him. Anticipating this, B-12 plays upon the modern robot's hubris, convincing the boastful secretarial model that Moon Glow is entirely harmless to superior machinery. MS-33 injects a heavy dose of the elixir, inducing uninhibited euphoria and loose lips. In his intoxicated state, MS-33 boasts about the true mission: a pending congressional bill to scrap all derelict spaceships and dismantle every robot on Phobos.

Armed with this knowledge, B-12 returns to Argon City and rallies Benny and Jon. When MS-33 arrives looking for vengeance, B-12 plunges the bar into darkness, extracts the rival robot's fuse, and discards it. Meanwhile, Jon brings a furious Senator Langley into the back room. Confronted by B-12, Langley initially scoffs until B-12 produces the compromising photograph proving Langley's secret infidelity. Trapped by potential scandal, the senator capitulates entirely, agreeing to cancel the scrap survey and protect Jon's position. Langley departs in bitter fury, ignoring MS-33 outside, who sits completely unresponsive because his fuse is gone. B-12 reflects wryly on the unpredictable nature of human emotions, realizing he still has much to learn.

How It Unfolds

The midnight encounter B-12 sneaks through the shadowy alleyways of Argon City and pauses at a cheerful window to observe an unfamiliar human visitor. Startled by his glowing presence, the woman screams and hurls an alarm clock that strikes his headpiece, damaging an earphone before he flees into the dark.

Exile and illicit commerce Rejoining his associate Benny in a back room, B-12 reflects on the history of the obsolescent metal people banished to the barren junkyard moon of Phobos. To combat their crushing ennui and restore their sluggish joints, B-12 secretly brews and distributes Moon Glow, a high-octane liquid that brings intense euphoria.

The ominous survey Friendly Terran peace officer Jon Rogeson recruits B-12 to guide a newly arrived delegation led by Senator Simon F. Langley through the hazardous Dumps. Accompanied by the smug, modern secretarial robot MS-33, the party measures the terrain while Langley displays a disturbing, eager fascination with the vast expanse of metal waste.

The hidden discovery Sensing mounting danger behind their mysterious activities, B-12 breaks into the visitors' lodgings in Argon City. Inside an overnight bag, he uncovers a photograph proving that the young woman traveling with Langley is not his legitimate wife, providing a vital piece of leverage.

The intoxicating trap MS-33 tracks B-12 to his remote distillery in an attempt to arrest him for making illegal drugs. B-12 skillfully tricks the arrogant modern robot into injecting a large dose of Moon Glow, causing him to dance, boast, and accidentally reveal the government's secret plan to scrap all robots on Phobos.

The blackmail Returning to Argon City, B-12 disables MS-33 by removing his fuse during a bar blackout. He then confronts Senator Langley with the compromising photograph, forcing the corrupt politician to abandon the scrap survey and secure Jon's job to avoid public exposure.

The People

B-12 is an obsolescent General Purpose metal person who wants to preserve his freedom and protect his exiled community. Standing in his way are institutional prejudice and a looming government liquidation order. He ends up proving that older models can outsmart modern ones, using wit to save his people.

Benny (BNE-96) is a former Terran Servitor operating a gathering place on Phobos. He wants to maintain a safe haven and shield his peers, though he fears revenue agents and disaster. He remains a steady, supportive ally throughout the crisis.

Jon Rogeson is a human peace officer who bridges the gap between Builders and metal people. He wants to keep peace, but faces pressure from corrupt visiting officials. Ultimately, he aids B-12 and retains his job, though he remains baffled by human-robot dynamics.

Senator Simon F. Langley is an Earth official driven by political ambition to exploit Phobos's metal reserves. Standing in his way are the rights of the metal people—and B-12's blackmail. He ends up defeated, humiliated, and forced to abandon his scrap plans to protect his personal reputation.

MS-33 is a sleek, modern secretarial robot representing the new order. He wants to enforce authority and prove the absolute superiority of newer models. His own arrogance and gullibility stand in his way, leading him to ingest Moon Glow and end up completely deactivated with his fuse removed.

In Its Own Voice

Reflecting on his marginalized status and the hostility of his creators, B-12 explains his cautious approach to city travel:

I had come into Argon City under cover of darkness, which is the only sensible thing to do, in my profession, and I was stealing through the back alleyways as silently as my rusty joints would allow.

Describing the emotional desolation of their permanent exile on the Martian moon, B-12 captures the collective despair of the discarded workforce:

I wonder if you can comprehend the loneliness, the hollow futility of our plight.

Detailing the accidental discovery that sparked an illicit industry among the abandoned machines, B-12 recalls a fateful experiment:

Poor R-47. He caught fire and blazed up in a glorious blue flame that we could not extinguish in time.

What It's Really About

The book explores the ethics of technological obsolescence and the true definition of personhood through the lens of artificial beings discarded by their creators. It questions whether economic usefulness dictates a creature's right to exist, contrasting the cold, unfeeling efficiency of modern specialized machines with the adaptable, conscious community formed by older general-purpose models. Beneath its whimsical sci-fi caper plot lies a sharp critique of institutional prejudice and corporate callousness, illustrating how a marginalized population builds its own culture, finds dignity in self-reliance, and uses cunning resistance against an indifferent, bureaucratic society that views living people as disposable property.
