Building Fission Reactors on the Moon
Mobile autonomous laser sintering. Lunar regolith fused into the structural and thermal infrastructure that makes surface fission possible.
The lunar economy runs on fission
The Moon has 14-day nights, no atmosphere, and energy demands that solar cannot meet.
Habitats, ISRU, propellant production, defense, and continuous operations all require kilowatt to
megawatt-class baseload power.
Surface fission is the only credible answer - and every other lunar venture depends on it.
- $1M+/ kgSURFACE DELIVERY COST
Every kilogram launched, transferred, and landed on the
Moon costs north of $1M. Mass is the constraint that
defines the architecture. - 1,000s kgREACTOR SUPPORT HARDWARE
Shielding, containment vessels, heat exchangers, and
structural housings dominate the mass budget of any
surface fission system. - 28 kgACTUAL REACTOR CORE
NASA's KRUSTY proved a 10 kW fission reactor runs on
a 28 kg uranium core. The core is small. Everything
around it is heavy.

The Moon's regolith is 40%+ iron, titanium, and aluminum by mass - the exact metals fission infrastructure requires. We don't ship the housing. We sinter it from the dust under the lander.

The science is done.
The execution is the moat.
Two foundational technologies underpin everything we build. Both have already been demonstrated. Our job is to close the gap between them by building an autonomous system that can manufacture reactor-grade infrastructure directly from lunar regolith at scale.

Validated lunar regolith sintering
Laser sintering of lunar regolith simulants has been demonstrated under flight-relevant conditions by the German Aerospace Center (DLR) and the Laser Zentrum Hannover (LZH). The physics works. We are productizing what the labs have already proven. -
NASA KRUSTY: 10 kW from a 28 kg core
Surface fission is not theoretical. NASA's KRUSTY experiment validated the full Kilopower reactor architecture in 2018. The remaining gap is mass-efficient infrastructure manufactured on the surface - and that is what we build.
