Astrobotic's LunaGrid is the first commercial attempt to solve the lunar power constraint with a power-as-a-service model. LunaGrid-Lite will demonstrate 1 kW transmission over 500m of cable in 2026-2027, with full commissioning of a 10 kW VSAT system at the lunar south pole in 2028. The $34.6M NASA contract and Honda partnership for regenerative fuel cells (to survive 14-day lunar nights) confirms that power infrastructure is the critical path for sustained lunar operations.
### Additional Evidence (extend)
*Source: [[2026-03-18-astrobotic-lunagrid-lite-cdr-flight-model]] | Added: 2026-03-18*
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.

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: Direct evidence of commercial lunar power infrastructure progress; critical prerequisite for He-3 extraction and other surface ISRU; the 1kW→50kW scaling timeline is a key constraint on commercial lunar operations
EXTRACTION HINT: The key insight is the scaling gap — 1kW demo (2026) vs. extraction-scale requirements (~1 MW+). This creates a timeline tension: Interlune's 2029 pilot plant would need more power than LunaGrid can deliver by then unless nuclear power (fission surface power) supplements the solar system.
