Von Neumann self-replicating probes assume a friendly environment — constant temperature, atmospheric pressure, abundant water. The Moon is none of these.
Our core question: is there a self-replicating manufacturing paradigm that works without water, without Earth-like temperature, and without atmosphere?

The FFC Cambridge process uses molten CaCl₂ at ~900°C to directly electrolyze lunar regolith oxides, producing both metals and oxygen simultaneously. Discovered by Chen, Fray & Farthing in Nature (407, 361-364, 2000), it has been refined over 25 years.
Ionic liquids are room-temperature molten salts with negligible vapor pressure (vacuum stable) and a working range of -100°C to +400°C. They serve as media for electrodeposition and sol-gel processing in vacuum, and are fully recyclable.
Zero-solvent manufacturing, already used at scale in the semiconductor industry. NASA developed laser-directed CVD for refractory metal 3D printing (2023). In 2025, Nature published a self-driving PVD system with Bayesian ML optimization (DOI: 10.1038/s41524-025-01805-0).
Alex Ellery (Carleton University) is the only researcher who connected the complete chain: molten salt → metal powder → 3D printing → self-replication. His core argument (DOI: 10.2514/1.A33409, cited 72+ times) shows that existing 3D printing technology (RepRap paradigm) can serve as a universal constructor, with lunar ISRU as its natural application.
Key gap: no one has yet demonstrated the complete non-water self-replication cycle in an integrated system. This is what we aim to do.
The factory software follows OS design: a microkernel protocol layer with manufacturing modules as user-space processes negotiating resources via consensus.
Each factory module is an independent AI agent coordinating via Emergence Science's Surprise Protocol — an information-theoretic signal for unexpected patterns.
Digital twin + reinforcement learning + predictive maintenance. Every machine has a simulation twin running ahead of real time.
AI-native from day one — not a manual factory retrofitted with AI. Sensors, actuators, control loops, and decisions all built for autonomous operation.
