The Shackleton Signal

Hard Sci-Fi, Sci-Fi, Space Exploration

In the eternal darkness of the moon, something ancient stirs.

When NASA’s Sentinel I satellite detects an impossible reflection and an eerie signal from Shackleton Crater, the world spirals into chaos. Beneath the lunar surface lies an alien artifact with a singular purpose: to be found.

With tensions between global powers at a breaking point, NASA astronaut Charlie Reid is thrust into a perilous mission where survival, science, and military ambition collide. As China races to seize the artifact, the lunar expedition veers toward catastrophe.

The truth beneath the moon’s surface could secure humanity’s future—or doom it entirely. In the face of the unknown, one question haunts them: who—or what—left it behind?

The future of mankind is on the line, and failure isn’t an option.
