First commercial nuclear-powered satellite launched

City Labs launched BOHR, the first commercial nuclear-powered satellite, aboard SpaceX's Transporter-17 rideshare mission on 10 July 2026. The tritium-based betavoltaic system provides continuous power independent of sunlight, enabling persistent operations in deep space and shadowed lunar regions where solar power fails. If you're building autonomous sensors, deep-space probes, or lunar systems, you no longer need to live within battery life or sunlight. City Labs just proved a regulatory path exists and a buyer exists - the constraint was always power, and that constraint is gone.
