 LunaGrid-Lite completed CDR in August 2025 and is fabricating flight hardware for a mid-2026 lunar deployment. The system will demonstrate 1 kW power transmission over 500m of cable. However, the scaling roadmap reveals a critical gap: 1 kW demo (2026) → 10 kW VSAT (2028) → 50 kW VSAT-XL (later). Commercial-scale He-3 extraction requires ~1.2 MW based on Interlune's excavator specs (100 tonnes/hour at 10x less power than 12 MW heat-based systems). This creates a 5-7 year gap between LunaGrid's demonstration capability and extraction-scale power requirements, making power availability a binding constraint on the 2029 pilot plant timeline unless supplemented by nuclear fission surface power.

+Moon Village Association analysis quantifies the power constraint for He-3 extraction specifically: traditional thermal methods require 12 MW solar concentration for 1,258 tonnes/hour processing, or seven-digit wattage for mobile rovers. With He-3 at 2mg/tonne concentration, this creates a power-mobility dilemma where neither distributed (impractical onboard power) nor centralized (transport bottleneck) architectures work at commercial scale.

 PRIMARY CONNECTION: [[power is the binding constraint on all space operations because every capability from ISRU to manufacturing to life support is power-limited]]
 WHY ARCHIVED: Provides the strongest counter-evidence to the "He-3 as viable first lunar resource" thesis; necessary for calibrating confidence on He-3 extraction claims
 EXTRACTION HINT: The key scope distinction is heat-based vs. non-thermal extraction. A claim accurately characterizing this paper must specify that it applies to heat-based methods only.

+- He-3 concentration on lunar surface: ~2 mg per tonne of regolith
+- He-3 predominantly found in particles <100 μm
+- Over 150 tonnes of regolith required per gram of He-3
+- He-3 distributed across approximately 40 million km² of lunar surface
+- Traditional thermal extraction requires 800°C heating
+- 12 MW solar concentrator needed for processing 1,258 tonnes/hour using thermal methods
+- Moon Village Association is a European Space Agency partner organization
