About this listen

Defense Mech by Ray Bradbury is a haunting and psychologically rich science fiction short story that explores the fragile boundary between reality and illusion. Set during a tense voyage from Earth to Mars, the narrative follows Halloway, a deeply anxious man whose terror of space threatens both his sanity and the mission itself. In a desperate bid to protect him, the ship’s psychiatrist deploys an experimental psychological “defense mechanism,” constructing an artificial reality in which Halloway believes he never left Earth.

With its signature blend of emotional depth, speculative science, and philosophical tension, Defense Mech examines fear, self-deception, and humanity’s instinct to seek comfort—even at the cost of truth. This classic Bradbury tale is a must-listen for fans of psychological science fiction and timeless speculative storytelling.
