5) Excavation and emplacement are non-trivial
Burial assumes you can do lunar civil engineering:
* place a heavy, delicate system
* backfill without crushing components
* maintain dust control

Practical constraints:
* excavation equipment must work in dust and vacuum
* low gravity changes traction and digging mechanics
* dust contamination can reduce radiator and connector reliability


6) The critical vulnerability: penetrations
Burial forces penetrations through the soil boundary:
* high-voltage power cables
* instrumentation harnesses
* coolant pipes
* vent lines
These penetrations are where buried designs can fail in subtle ways:

A) Thermal stress concentration
😎 Leak and freeze risk
Any coolant line that leaks in vacuum becomes:
* loss of working fluid
* loss of heat transport
C) Dust intrusion and connector degradation
D) Single-point failures hiding in “simple” interfaces


Mitigation pattern :

* multiple independent penetrations
* redundant feeders
* isolate-able segments
* conservative derating of connectors
* health monitoring on feedthrough integrity
