Texas-based Space Ocean Corporation has partnered with Space Nuclear Power Corporation to test a microreactor aboard its satellite, marking a significant step forward in space nuclear technology.

The collaboration involves testing Space Nukes’ 10-kilowatt nuclear reactor on Space Ocean's ALV-N satellite, with the possibility of future use in lunar and planetary missions if the reactor meets performance standards.

This microreactor is based on the KRUSTY reactor developed by Los Alamos National Laboratory for NASA, which operates at over four kilowatts and does not require new infrastructure, making it suitable for space applications.

The first-generation reactors, capable of producing 1 to 20 kWe, are designed to operate autonomously for decades, weigh around 2,866 pounds (1,300 kg), and feature a highly enriched Uranium core, supporting deep space missions.

Space Ocean plans to launch its first demonstration mission in 2027 to power satellites up to 5,000 kilograms and support long-term space exploration, including in-orbit fluid logistics.

The collaboration emphasizes integrating nuclear reactors with fluid delivery systems, collecting operational data for Technology Readiness Level 9 certification, and exploring additional space infrastructure and commercial opportunities.

Ultimately, Space Ocean aims to enable spacecraft to generate and manage energy well beyond Earth orbit, reducing launch frequency and extending satellite lifespans.
