Five milestones to an in-space fuel supply chain

Enrichment Prototype
01 — 2025 Q3

Space-Based Enrichment Prototype

Prototype micro-satellite with an inert stand-in for nuclear material. Moves development out of the public-private partnership model and into a faster, private innovation loop.

HALEU Licensure
02 — 2026 Q1

Obtain HALEU Licensure

Secure the regulatory approvals to work with high-assay low-enriched uranium and become the first company licensed to enrich nuclear fuel in space.

Robotic Assembly
03 — 2027 Q2

Robotic Nuclear Engine Assembly

Deploy a robotic platform capable of refueling a small modular reactor on orbit, demonstrating the autonomous assembly pipeline for the full engine program.

NTP Demo
04 — 2028

Space Nuclear Rocket Demonstration

Launch an uncrewed nuclear reactor to orbit and load uranium fuel in situ — the first in-space fueling and ignition demonstration of a nuclear thermal engine.

Vision '32
05 — 2032

Vision '32

Full space-based fuel supply chain — enrichment through fuel manufacturing — enabling rapid refueling of a nuclear rocket booster fleet and commercial freight to interplanetary destinations.

// Mission

We are building nuclear thermal propulsion for the next generation of crewed and robotic missions — engines that cut transit times to Mars in half and open the rest of the solar system to fast, capable spacecraft.

// Team

A small group of reactor physicists,
propulsion engineers, and operators.
