To deliver high-performance nuclear thermal propulsion systems that power scalable logistics and infrastructure beyond low Earth orbit.
We exist to enable faster transit, lower costs, and commercial viability across the next frontier of space development.
We envision a space economy where materials, equipment, and people move through cislunar space and beyond as reliably as shipping containers move across the world today.
In that future, Dark Fission provides the propulsion backbone-connecting low Earth orbit with the Moon, Mars, and everything in between. We see ourselves as the freight engine of deep space: efficient, powerful, reusable, and indispensable.
We build what we promise, deliver on time, and scale integrity. At Dark Fission, we operate in the light, with transparency, precision, and purpose.
Dark Fission is building the propulsion system that will enable humanity's next leap: fast, reusable, and cost-efficient nuclear thermal propulsion (NTP).
We exist to solve the fundamental transportation problem in space. Rockets can get cargo to orbit—but beyond that, it's too slow, too expensive, and too limited. Our system closes that gap. With 3x the efficiency of chemical propulsion and built-in reusability, our NTP platform delivers the power and performance required for real infrastructure in cislunar space and beyond.
Our team brings together experts from nuclear engineering, aerospace design, regulatory strategy, and national security. We're not experimenting with science projects—we're delivering flight-ready systems that move the space economy from aspiration to action.
We believe the future of space is built on speed, scale, and sustainability. That's exactly what we're engineering.
