SpaceX launches first commercial nuclear-powered satellite, BOHR, testing advanced tritium energy technology for future space exploration missions.

The first commercially built nuclear-powered satellite has reached orbit after a successful SpaceX satellite launch aboard the Falcon 9 rocket. Developed by Florida-based City Labs, the BOHR (Betavoltaic Orbital High-Reliability) cubesat launched on SpaceX’s Transporter-17 rideshare mission from Vandenberg Space Force Base, marking a major milestone for commercial nuclear technology in space.

The mission is testing City Labs’ NanoTritium betavoltaic micropower technology, designed to provide long-duration energy solutions beyond traditional solar-powered spacecraft.

BOHR Tests Next-Generation Space Power Technology

The SpaceX space mission carried 81 payloads before deploying satellites into multiple orbital destinations. BOHR’s primary objective is to evaluate the performance of City Labs’ tritium-based power technology in the harsh environment of space.

Unlike conventional solar systems, betavoltaic technology converts energy from radioactive decay directly into electricity through a semiconductor process. While BOHR still uses solar power for regular satellite operations, the demonstration could support future spacecraft operating in locations where sunlight is limited.

Peter Cabauy, CEO of City Labs -

“This is a historic step for commercial nuclear power in space.”

Key points from the nuclear satellite mission:

  • First commercial nuclear-powered satellite reaches orbit

  • BOHR launched aboard SpaceX Falcon 9 rocket

  • City Labs developed NanoTritium power technology

  • Mission tests long-duration spacecraft energy solutions

  • Technology targets challenging deep-space environments

Nuclear Power Could Transform Future Space Exploration

City Labs believes its compact tritium-based systems could eventually support missions requiring continuous power, including exploration of permanently shadowed regions near the Moon’s poles. These areas are considered important for future lunar infrastructure because of their potential water ice resources.

The development received funding through a Department of Defense contract and became the first nuclear-powered mission approved under the Federal Aviation Administration’s nuclear launch process connected to National Security Presidential Memorandum-20.

The nuclear-powered commercial satellite technology is designed with safety considerations, including low radiation output and compatibility with commercial launch requirements. City Labs expects future versions of the system could contribute to national defense missions and private space exploration.

As a result, Business Fortune believes that nuclear-powered satellites have the potential to redefine future space exploration by providing reliable, long-duration energy solutions.
