Every plan for permanent lunar presence runs into the same physics: fission is the only viable power source through 14-day lunar nights. NASA’s KRUSTY program proved a 10 kW reactor runs on a 28 kg uranium core - small enough to launch.

But the infrastructure around that core - radiation shielding, containment vessels, heat exchangers, structural foundations - weighs thousands of kilograms. At $1M+ per kg to the lunar surface, launching it is economically impossible at scale.

So don’t launch it. Build it there.

Lunar Forge is developing mobile autonomous laser sintering systems that manufacture reactor-grade infrastructure directly from lunar regolith. The system surveys the terrain, reads regolith composition in real time, and sinters structural components with adaptive process control - fully autonomous, no human operators required.

Launch the core. Build the rest on the Moon.

This isn’t a nice-to-have. Without surface power, there is no lunar economy. Every mining operation, propellant depot, research station, and logistics hub depends on continuous energy. Fission is the backbone - and in-situ manufactured reactor infrastructure is what makes the unit economics of everything else on the Moon work.

We are the critical manufacturing layer that unlocks the entire lunar economy.
