A little about this puzzle

Inside a sealed Mars greenhouse dining room, a gardener rests a mature dwarf tomato pot on the harvest bench while a single-arm service robot gently touches its rim with a soft gripper. Two colleagues prepare turkey and salad at the dining table. A central cabinet holds the terminal, caliper and battery case, and red rock slopes appear beyond the closed windows.
