No wall of equal cards, no command panel. Mascon stacks the habitat by depth — surface dust, the airlock, the pressurized core where one person breathes, then bedrock and the mass below. A meter ruler keeps you oriented the whole way down.
Loose lunar dust over the buried module. Navigation and context live up here, in the light.
Where the operator stands. Oxygen, pressure and thermal read out as a live dot-matrix.
Anchor stress and the mass concentration below. Deepest, densest, quietest — risk surfaces here.
Shelter mass settled into bedrock; no creep on the watch interval.
Coolant return micro-leak. Isolate before the airlock cycle.
Mass concentration noted at +12 mGal. Recorded, no action.
