This is my fav short story that I’ve posted so far.

It’s a mixture of early space fiction, psychological horror, and cosmic horror.

Three men stationed on Mars become convinced the planet is somehow overcrowded, even though only fifteen Earthmen live there. So they steal a spaceship and set course for Jupiter.

The journey takes an unexpected turn when their ship crashes on the remote asteroid 25 Phocea, where something waits among the rocks.

It first appeared in the October 1932 issue of Wonder Stories.
