“Redemption Cairn” is a science fiction short story by Stanley G. Weinbaum that first appeared in the March 1936 issue of Astounding Stories. “Redemption Cairn” is the only Weinbaum story set on Europa.
Jack Sands, the story’s narrator, is a spaceship pilot down on his luck. In September 2111y, he is about to be evicted from a flophouse when he is recruited by his old friend Captain Harris Henshaw to co-pilot an expedition to Europa. Sands is one of only two survivors of a previous visit to the Jovian moon. The other was his drug-addled co-pilot Kratska, who crashed the expedition’s ship, the Hera, while landing it on Earth. While Sands lay unconscious in a hospital, Kratska put the blame for the crash on him, ruining his reputation. Kratska has since disappeared.
