Florida-based City Labs has launched BOHR (Betavoltaic Orbital HighReliability) — the world’s first commercial nuclear-powered satellite and first nuclear CubeSat — aboard SpaceX’s Transporter-17 rideshare mission on July 7, 2026. BOHR demonstrates City Labs’ NanoTritium™ betavoltaic technology in orbit, converting the natural decay of tritium into continuous, always-on power that doesn’t depend on sunlight or batteries.
