US firms to trial nuclear reactor aboard satellite for space travel

Texas-based Space Ocean Corporation and Space Nuclear Power Corporation have signed a Letter of Intent (LOI) to collaborate on testing a 10-kilowatt micro nuclear reactor aboard Space Ocean’s ALV-N satellite. This partnership aims to integrate Space Nukes’ reactor technology with Space Ocean’s fluid logistics and delivery infrastructure to support sustained orbital and planetary missions, including lunar and deep space operations. If successful, Space Nukes will become a key supplier of nuclear power units for future Space Ocean missions. The reactor technology is based on the KRUSTY design developed by Los Alamos National Laboratory for NASA, which has been ground-tested and requires no further development or testing, offering a scalable, reliable power source for long-duration space missions. Space Nukes’ first-generation reactors, ranging from 1 to 20 kWe, are compact and lightweight enough for various deep space applications and are designed to operate autonomously for decades. The 10-kWe variant weighs approximately 1,300 kg and uses a highly
