Floor of Heaven

After half a century of preparation, the Ad Astra carries three astronauts toward Mars: pragmatic expedition leader Bryan, easygoing Hughes, and Williams, an intensely ambitious astrogator who cares more for the stars than for people. Their journey is marked by quiet routines, playful arguments, and Williams’s awe at the jeweled heavens beyond the ship’s windows. At last, Mars grows from a distant red point into a stark, forbidding world.

The landing promises little more than planting a flag and recording data, but a sudden tremor turns the expedition into a fight for survival. When the planet opens beneath his crewmates, Williams must make an agonizing decision and launch the ship alone. Coasting back toward Earth, he finds the familiar silence of space changed—and begins to confront the unsettling possibility that the mission has brought back more than its records and memories. This classic science-fiction tale blends space exploration, human ambition, and a creeping sense of cosmic unease.
