Collision Orbit

Out in the Asteroid Belt, survival depends on reputation, routine, and knowing when to look harmless. Sam runs a lonely orbital supply stop where spacemen drift in, browse, eat, and move on without trouble. When armed fugitives arrive unannounced and decide the place is theirs, Sam is forced into a dangerous role he never planned to play.

The invaders believe control is simple: take the ship, silence the signals, and remove the owner. What they don't see is how much of the Belt listens, how closely, and how quietly. Every order, every threat, and every careless assumption tightens a situation where violence is easy but escape is not. Sam must endure humiliation, physical danger, and the steady narrowing of options while waiting for a single moment when the balance can shift.

Collision Orbit unfolds with calm confidence and rising tension, driven by practical thinking rather than heroics. Katherine MacLean crafts a setting where technology is functional, improvised, and deeply human, and where intelligence matters more than firepower. The story rewards patience, sharp observation, and the understanding that frontier justice doesn't arrive with sirens—it drifts in silently.

Katherine MacLean was a prolific science fiction writer whose work appeared frequently in Astounding Science Fiction, Galaxy, and Science Fiction Adventures. She collaborated with Charles V. De Vet and later gained wide recognition for stories such as The Missing Man and the novel The Cosmic Computer. Collision Orbit reflects her strength in problem-solving narratives, where believable science, social systems, and human behavior collide under pressure.
