First Commercial Nuclear Satellite Signals New Era in Space Power
City Labs’ BOHR cubesat, launched on SpaceX’s Transporter-17, tests NanoTritium betavoltaic power in orbit—the first commercial nuclear satellite—demonstrating continuous power for instruments without sunlight while solar power handles general operations; the mission also earned FAA approval under a nuclear-launch pathway, signaling a regulatory milestone for future commercial nuclear space power.
