My short story "Mercury" was recently published by The Story Shack:

Because the surface of Mercury is as hot as molten lead, its inhabitants live underground. It has an atmosphere, though, and properly suited up one can live on the surface for brief periods of time.

The planet is heavily cratered, much like Earth's moon. It has cliffs the color of ochre that extend as much as a mile into the sky. Evidence of ancient lava flows are everywhere. There are numerous shallow basins and ringed craters. A good percentage of s surface is covered by plains.
