Atomos is designing and space-rating nuclear fission reactors for long-duration and highly-demanding space applications.

Fission power changes the paradigm and opens a new frontier of possibilities in space exploration and development. Atomos is building an optimized in-space transportation network from high-LEO to anywhere; we are first building nuclear-powered space tugs for precision orbital insertion of spacecraft and cargo hauling. Our small modular space nuclear reactors will also enable an entirely new scale of power-intensive space operations, helping to advance companies in space mining, manufacturing, and more.

Extended Operations

Spacecraft capabilities are severely limited by available propellant. Nuclear fission systems have high power densities and long service lives, increasing the available electric power a spacecraft can utilize. Coupling the heightened electrical power output of Atomos reactors with efficient plasma thrusters can enable significantly extended operational lifetimes.

Higher Power

Electrical power in space is a limited and precious commodity, particularly when far from the sun. High power applications require tens of square meters of solar panels, which are cumbersome and scale poorly with power. Atomos reactors will offer order-of-magnitude expansions to spacecraft power budgets, with the ability to scale power levels even higher.

Faster Transfers

Transfer times for deep space missions are prohibitively long, which is problematic for many commercial applications and human spaceflight. Atomos’ nuclear electric propulsion architecture, when scaled for high-mass and long-distance operations, can outperform solar, chemical, and nuclear thermal propulsion technologies.
