Ethos Space Resources

Ethos Space is a lunar mining and construction company focused on producing infrastructure inputs on the Moon rather than launching them from Earth. Its stated technical approach centers on a single process chain applied to lunar regolith, which the company describes as consisting primarily of silicon, aluminum and oxygen: the regolith is melted, electrolyzed and purified, yielding construction materials, rocket propellant and solar-grade silicon at successive levels of refinement.

The company frames its work around early lunar surface activity rather than long-horizon systems. It positions landing pads, propellant for return flights, and silicon for power generation as the first-order needs that precede later concepts such as a mass driver launching AI satellites, which it characterizes as a roughly ten-year buildout. Internally held company information also describes named product lines for lunar construction material (Durandal) and onsite propellant production (Prometheus), materials for space-based data centers, and published research on lunar and planetary resources including silicon, water, critical minerals and helium-3.
