Adventure6 min read·1,253 words

A desperate hauling crew bets their entire business on a hair-brained delivery: transporting a specific, wedding-ready asteroid across the solar system for a wealthy client.

In Short

This brisk science fiction tale follows Bob Parker and his partner, Queazy, two struggling space truckers who accept a bizarre contract to deliver a precisely measured asteroid to Earth. Along the way, they encounter a runaway heiress and a rival firm of cutthroat competitors. The narrative explores the high-stakes world of interplanetary commerce with a blend of slapstick humor and clever, high-concept problem-solving. It remains a memorable curiosity for its inventive use of physics and its charming, fast-paced depiction of 1940s-style space adventuring.

The Story

Bob Parker and his partner, Queazy, operate a failing interplanetary hauling company on Mars. Desperate to avoid working in the glass factories, they spot a lucrative opportunity in a niche trend: wealthy eccentrics wanting to hold weddings on top of asteroids. They accept a contract from the wealthy Andrew S. Burnside, who demands a very specific asteroid—one that meets rigorous size and composition requirements—to be delivered to his Philadelphia estate by June 2nd.

After a surprisingly lucky search, the partners locate the perfect rock. However, they find it already occupied by a mysterious woman named Starre Lowenthal. She refuses to leave, claiming the asteroid as her home under common law. While Bob and Queazy argue with her, they are ambushed by the Saylor brothers, a rival hauling firm. The Saylors paralyze the trio with spastic rays, leaving them to drift in deep space, and steal the asteroid.

After waking in the void, Starre manages to reach her ship and rescue the men. She reveals her true identity: she is Burnside’s granddaughter. She admits she picked out the asteroid herself to force her grandfather into a wedding she didn't want, hoping to stall for time. Now, with the Saylors ahead of them and the deadline looming, the three form an uneasy alliance.

Bob realizes that while the Saylors have a faster ship, their massive cargo—the asteroid—limits their speed. He invents a "cosmic yo-yo" by tethering Starre’s dumbbell-shaped ship to his own. Using this improvised weapon, they repeatedly slam the smaller ship into the Saylors’ vessel. The maneuver works; the Saylors, fearing for their lives, abandon the asteroid.

Bob and Queazy reclaim the rock, but the challenge remains: delivering an asteroid without falling into legal or romantic traps. Bob spends the final days making intense calculations. On the day of the wedding, he drops the asteroid onto the lawn at the exact moment requested. Just as the ceremony begins, the asteroid suddenly liquifies, revealing that it was a massive, frozen block of mercury encased in a thin shell of ore. The wedding is ruined, the guests are sent running, and Bob and Starre make a quick getaway. Later, in a hotel room, Bob explains to an astonished Queazy that he knew the mercury would thaw upon entry into the atmosphere. Because the contract specified cinnabar—the primary ore of mercury—the delivery is technically complete, and the fortune is theirs to keep.

How It Unfolds

The discovery Bob and Queazy locate an asteroid that matches the exact dimensions and mineral specifications requested by their client. Their joy is short-lived as they realize they must secure the rock before their unscrupulous rivals learn of the deal.

The standoff The arrival of a beautiful, stubborn woman claiming ownership of the asteroid forces a tense confrontation. This stalemate is abruptly broken when the rival Saylor brothers arrive and incapacitate the group, leaving them for dead in space.

The alliance After a narrow escape, the three survivors discover their common enemy and decide to work together. They devise a plan to intercept the rivals by using their ships as a "cosmic yo-yo" to batter the enemy vessel.

The final delivery The heroes succeed in reclaiming the asteroid and deliver it to Earth with scientific precision. By exploiting the asteroid's internal composition, Bob ensures the wedding ceremony ends in a chaotic, mercury-soaked collapse, securing his payment and his future with Starre.

The People

Bob Parker is the ambitious, impulsive, and slightly hot-headed president of the Interplanetary Hauling & Moving Co. He is driven by a desperate need to save his business, but his tactical ingenuity—and his growing affection for Starre—eventually drives him toward a more creative solution than simple delivery.

Queazy (Quentin Zuyler) serves as the steady, capable pilot and voice of reason. While his massive size and mechanical skill make him an ideal partner for Bob, he remains the grounded, skeptical anchor who ensures the ship survives their wilder schemes.

Starre Lowenthal is the catalyst for the conflict. Initially presented as a cold, inhospitable squatter, she reveals herself to be a young woman trapped by her grandfather’s whims. Her transformation from a frightened pawn into an active participant in the mission allows her to escape a marriage she does not want.

Andrew S. Burnside is the archetypal wealthy patriarch, a "stubborn old hoot-owl" who views his family and his employees as pieces on a chessboard. He remains the looming antagonist whose rigid expectations force the protagonists to think outside the box to achieve their freedom.

In Its Own Voice

"Want an asteroid in your backyard? We supply 'em cheap."

The company’s advertisement, found in a newspaper, sets the tone for the absurdly commercialized future of the asteroid belt.

"I'm sure you don't understand the conditions--I want to make some conversation, lady."

Bob attempts to use his limited charm on the mysterious woman guarding the asteroid, leading to their first real interaction.

"I couldn't get married on an asteroid if the asteroid wasn't there any more, could I, Queazy?"

Starre realizes the genius of Bob’s plan as the asteroid dissolves into a literal pool of mercury during her wedding.

What It's Really About

At its heart, the story is a rebellion against the crushing weight of institutional expectations. Whether it is the pressure of corporate competition or the stifling demands of a wealthy family, the protagonists are constantly told what they must do and who they must be. The "yo-yo" maneuver and the melting asteroid are more than just plot points; they are symbolic rejections of the status quo. Bob Parker argues that even in a universe where everything has a price tag, one can use the laws of physics and a bit of wit to break free from the roles forced upon them by power-hungry men.

Why Read It Today

This book offers a fascinating look at the mid-century "pulp" era’s approach to science fiction. Readers will likely enjoy the brisk pace and the genuine warmth between the three leads. The prose is unpretentious and filled with a playful, inventive energy that makes the impossible feats of space travel feel like a wild, high-stakes game of pool played with celestial bodies.

However, a modern reader should be prepared for the period-typical attitudes regarding gender dynamics. Bob’s immediate desire to "give [the girl] the licking of her life" and the general dismissiveness toward Starre’s agency in the first half reflect the social norms of 1945. These elements are woven into the fabric of the story, though the plot eventually pivots to show the characters working as a true team. The dialogue is snappy and often funny, echoing the screwball comedies of its time. If you can appreciate the historical context, you will find a charming, inventive tale that doesn't take itself too seriously—a story that balances the cold, lonely vacuum of space with the human desire to pull off one last, improbable victory. It is a light, imaginative read that delivers exactly what it promises: an asteroid in a backyard and a very messy wedding.
