Hot Planet
A crew of scientists and engineers has finally set foot on Mercury, a world long thought to be air‑less and dead. Their landing is anything but smooth, as relentless tremors shake the planet and threaten to wreck their delicate equipment. With limited time before the next launch window, they scramble to record seismic data, study odd crystal growths, and piece together why a thin atmosphere seems to be forming around the scorched planet.
Tensions run high as the team juggles scarce tape supplies, a strict weight budget for the return trip, and the ever‑present danger of the planet’s constant quakes. Each specialist—geophysicist, biologist, stratigrapher, and the ship’s captain—brings a different perspective to the mystery, hoping their combined observations will finally explain Mercury’s unexpected change. The story captures the blend of scientific curiosity and human frailty that defines early space exploration.
