## Content

Astrobotic announced in August 2025 that LunaGrid-Lite completed Critical Design Review (CDR) and has moved to flight model fabrication and assembly.

**LunaGrid-Lite mission specs:**
- Deploy 500m of ultra-light cable across lunar landscape
- Transmit 1 kilowatt of power — first power transmission demonstration on the Moon
- Carrier: Astrobotic CubeRover
- CDR completed: August 2025
- System Integration Review (SIR): Q4 2025
- Flight-ready target: Q2 2026
- Deployment on lunar surface: mid-2026 (NET)
- NASA contract value: $34.6M

**LunaGrid roadmap:**
- LunaGrid-Lite: 1 kW demo (2026-2027)
- LunaGrid (VSAT solar): 10 kW (2028, lunar south pole)
- LunaGrid VSAT-XL: 50 kW (later)
- Honda partnership: regenerative fuel cells for 14-day lunar night survival

**Mission objectives:**
- First commercial power transmission on Moon
- Validate cable deployment in lunar environment
- Demonstrate power-as-a-service model for lunar surface

**Delivery vehicle:** LunaGrid-Lite components will travel on a CLPS lander. Given the mission date of mid-2026, this aligns with the Griffin-1 NET July 2026 manifest (which includes multiple Astrobotic payloads).

## Agent Notes
**Why this matters:** Power is the binding constraint for lunar surface operations, including He-3 extraction. LunaGrid-Lite is the first attempt to build commercial lunar surface power infrastructure. CDR completion means the design is frozen and hardware is being built — this is flight-serious engineering, not a concept study.

**What surprised me:** 1 kW is a very modest starting point. Interlune's excavator processes 100 tonnes/hour and claims 10x less power than 12 MW heat-based systems — implying ~1.2 MW. LunaGrid's path from 1 kW (2026 demo) to 10 kW (2028) to 50 kW (later) would take until at least 2030-2032 to reach the scale Interlune needs for a commercial plant. The power availability timeline may be a binding constraint on Interlune's 2029 pilot plant timeline.

**What I expected but didn't find:** LunaGrid power pricing ($/kWh or $/W) for commercial customers. The "power-as-a-service" model implies pricing, but no figures were public. This is the key economic variable for modeling Interlune's operating costs.

**KB connections:**
- [[power is the binding constraint on all space operations because every capability from ISRU to manufacturing to life support is power-limited]] — LunaGrid is the direct engineering attempt to address this constraint at the surface level
- the self-sustaining space operations threshold requires closing three interdependent loops simultaneously -- power water and manufacturing — power loop closing is the first prerequisite; LunaGrid addresses power for surface operations

**Extraction hints:**
- Update claim on power constraint to reflect LunaGrid-Lite's CDR completion and flight model status — commercial power infrastructure for the Moon is 12+ months from demonstration
- New claim candidate: "LunaGrid-Lite represents the first attempt to close the power loop for lunar surface operations commercially, but the 1kW→10kW→50kW roadmap creates a 5-7 year gap between current demonstration and the power levels required for commercial-scale He-3 extraction"

## Curator Notes
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.
