City Labs to Launch First Nuclear-Powered Satellite, BOHR

City Labs launched its BOHR satellite aboard a SpaceX Transporter-17 mission to demonstrate the performance of NanoTritium betavoltaic technology in orbit. The spacecraft utilizes this nuclear power source to maintain continuous operation of its payload independent of solar energy, marking the first commercial deployment of such technology on a CubeSat.

This mission serves as a regulatory pathfinder, representing the first commercial nuclear project to complete the Federal Aviation Administration launch approval process under National Security Presidential Memorandum-20. By validating the safety and reliability of tritium-based power systems in space, the project establishes a framework for future commercial and national security missions requiring persistent power in environments where solar or battery systems are insufficient.

City Labs' BOHR satellite, the world's first commercial nuclear-powered spacecraft, launches aboard SpaceX Transporter-17 using NanoTritium™ technology.

Miami, FL — July 7, 2026 — City Labs today announced that its BOHR (Betavoltaic Orbital High-Reliability) satellite, the world's first commercial nuclear-powered satellite and first nuclear CubeSat, has been officially manifested aboard SpaceX Transporter-17, a rideshare mission launched today.

The BOHR mission demonstrates City Labs' proprietary NanoTritium™ betavoltaic technology in orbit as a dedicated payload power source, providing continuous, long-duration electrical power independent of solar energy. This milestone establishes a new class of spacecraft capabilities, enabling persistent operation of critical subsystems where traditional power systems fall short. This includes deep space, permanently shadowed lunar regions, and long-duration autonomous sensor networks.
