Miami startup launches world's first commercial nuclear-powered satellite
City Labs, a Miami-based company, successfully launched BOHR, the world's first commercially operated nuclear-powered satellite, on a SpaceX Transporter-17 rideshare mission on July 7, 2026. The softball-sized CubeSat uses City Labs' proprietary NanoTritium betavoltaic technology, which generates power from the natural decay of tritium rather than from solar panels or traditional batteries. This is significant because the satellite can operate continuously in darkness and extreme cold, making it useful for exploring places like the moon's permanently shadowed craters and deep space where sunlight is unavailable. The mission also achieved a regulatory breakthrough: it became the first commercial nuclear mission to successfully navigate the FAA's new approval pathway for nuclear launches, established under the 2019 National Security Presidential Memorandum-20. The tritium systems operate at extremely low radiation levels and are considered safe for commercial handling.
Key facts
- BOHR is a 1U CubeSat roughly the size of a softball launched on July 7, 2026
- NanoTritium betavoltaic battery produces power in the nanowatt to microwatt range
- Tritium has a 12.3-year half-life, providing continuous power for over 20 years
- FAA issued payload authorization on September 30, 2025, the first under the NSPM-20 framework
- Mission was funded by the Department of Defense and supported by NASA and Air Force Research Laboratory
- City Labs' tritium-based systems can be legally shipped to residential addresses due to extremely low radiation levels
How different outlets framed it
Right-leaning coverage: Coverage frames the mission as advancing US national security and defense capabilities, noting Department of Defense funding and support from military agencies. Sources emphasize how tritium-based systems offer less vulnerable, more robust power sources for military satellites compared to solar power, supporting US space dominance.
