The tunnel ramped steeply downward in the little worldlet’s faint gravity. Soon, the faint glow of the bulbs faded behind her. She adjusted the beam on her helmet and stepped lightly over the wreckage of yet another ancient airlock, peering into the pitch-blackness of the next yawning chamber. Her headlamp cast a stark, bright oval onto what had not been exposed to light in aeons.

The rock wall sparkled where her beam hit the facets of sheared, platinum-colored chondrules—shiny little gobs of native metal condensed out of the very solar nebula nearly five billion years before. They glittered delicately.

She knew full well (in her forebrain!) that nothing could still be alive down here. Nothing could harm her. And yet, with brain and guts evolved on a savannah half a billion miles away, it was small wonder she felt a shiver of the old fight-flight fever. Her breath came rapidly. In this place it almost seemed there must be ghosts.

She motioned with her left hand. “Drone three, bring up the lights.”

“Yesss,” came the response in a dull monotone. The semisentient robot, stilt-legged for asteroid work, stalked delicately over the rubble, in order to disturb as little as possible.

“Illuminate the far wall,” she told it.

“Yesss.” It swiveled. Suddenly there was stark light. Ursula gasped.

Across the dust-covered chamber were easily recognizable tables and chairs, carved from the very rock floor. Among them lay dozens of small mummies. Cold vacuum had preserved the bipeds, huddled together as if for warmth in this, their final refuge.

The faceted eyes of the alien colonists had collapsed from the evaporation of moisture. The pulled-back flesh left the creatures grinning—a rictus that made a seeming mockery of the aeons they had waited here.

She set foot lightly on the dust. “They even had little ones,” she sighed. Several full-sized mummies lay slumped around much smaller figures, as if to protect them from something.
