A whole world.
Just outside.

Mission control is under a flowerpot. The deep-space antenna is a bent paper clip. At 07:04, Pebble rolls down a ramp made from a lolly stick and becomes the first member of the expedition to encounter a worm.

Initial reports describe an “uncooperative flexible terrain feature.” The classification is quickly revised.

Big discoveries. Small footprint.

The crew has three possible destinations. A leaf drifts across the Birdbath Sea. A moss forest conceals a canopy at knee height, provided your knees are very close to the ground. Beyond it, a broken terracotta pot forms a ridge with a gap in the middle.

Your job is to choose a machine and an instrument that can answer a particular question, then get the machine home. The expedition is deliberately simple. A camera cannot do a tether’s job. Good software cannot make a boat climb a hill.

“We have discovered a second sun.”— Pip, shortly before learning about the porch light

What is imagined?

The crew, destinations, energy units and mission results are fiction. Each outcome is a written branch, not a live robot simulation or shared vote. Your last 30 field logs stay in this browser and can be exported.

The underlying idea is practical: match the body, sensing and recovery plan to the environment. To see what very small real machines have demonstrated, follow the evidence in our scale explorer.
