Mystery in Space #6

In "The Boy Who Saved the Earth!", a young boy stumbles upon a tiny, alien spacecraft that’s just landed on Earth—unaware it’s the vanguard of an imminent invasion from the distant world of Kadar-Zee. As the planet’s fate hangs in the balance, he treats the strange craft as a toy, setting off a chain of events that could change everything.

In "The Man Who Hated Science!", Professor Mason Halloway travels a thousand years into the future, only to find a world scorched and silent—believing he’s arrived in the past. When survivors emerge, speaking English and claiming it’s the year 2952, Halloway learns the shocking truth: the very scientific advance meant to heal humanity, the Roentgen ray, ultimately poisoned the planet.

In "Cowboy on Mars!" from *Mystery in Space* #6 (1952), the notorious outlaw The Rio Kid finds himself fleeing lawman Rink Nevins into a mysterious cave—only to be whisked away by a strange beam of light to the red planet Mars. There, a band of Martian criminals, intrigued by his outlaw skills, see in him a perfect leader for their own brand of mischief.
