Stellar Nuclear is at the forefront of pioneering compact nuclear microreactor concepts to cater to the demanding energy needs of space exploration. Their innovations target critical missions on the Moon and Mars, as well as ambitious deep-space missions to distant celestial bodies like icy moons and gas giants.

The systems are engineered to deliver sustainable and reliable power essential for both robotic and future human expeditions. These microreactors play a pivotal role in sustaining essential mission operations, including powering instruments, enabling mobility, facilitating communications, and supporting In-Situ Resource Utilization (ISRU), habitats, and extensive surface infrastructure for long-duration stays.

Stellar Nuclear is focused on three key mission-driven architectures: high-power Radioisotope Power Systems (RPS) integrated with Stirling conversion for lunar surface missions, fission microreactors paired with thermoelectric generators to provide small-scale kilowatt-class power solutions, and versatile modular microreactors poised for future nuclear electric and nuclear thermal propulsion system applications.
