Regolith Compaction Process
Vibratory + Static Compaction for Maximum Density
The regolith compaction process utilizes vibratory and static rollers to densify loose regolith overburden from 1300 kg/m³ to 1800 kg/m³, increasing radiation shielding effectiveness by approximately 25%. Operating under 1/6 g requires higher-frequency vibration than terrestrial methods to settle the granular particles, though the complete absence of moisture in the lunar vacuum prevents moisture interference during compaction. Mechanized as a 200 kg robotic unit equipped with rolled-steel drums, hardened steel teeth, and vibrator motors, the system operates alongside hauler fleets, processing 5 m³/hour of material at a continuous power consumption of 500 W.

Purpose
Compaction process (vibratory + static rollers) increasing regolith density of the overburden from loose 1300 kg/m^3 to compacted 1800 kg/m^3 — improving shielding effectiveness.
Context
Child of L2-RAD-REG within the Lunar Ark system
Principles
- ▸Vibratory compaction densifies granular regolith
- ▸Static roller follow-up achieves final density
- ▸Moisture-free regolith compaction in vacuum
- ▸Compaction increases shielding effectiveness by ~25%
- ▸Densification reduces overburden volume needed
Typical implementations

- ▸Mars HabEx compaction studies
- ▸NASA construction equipment R&D
Lunar considerations
- ▸Lunar dust dryness aids compaction (no moisture interference)
- ▸Robotic compactor operates with hauler fleet
- ▸1/6 g requires higher-frequency vibration vs Earth
