Nuclear-Powered Satellite Launch Aboard SpaceX Rocket

The Miami-based City Labs is all set to launch the world’s first commercial nuclear-powered satellite into orbit.

Solar panels have some challenges. When a satellite slips into the shadow of the Earth, hits a permanently dark lunar crater, or drifts into deep space, its solar arrays become useless. Batteries can step in, but they eventually die.

City Labs thinks nuclear energy could solve this persistent problem. On July 7, the company announced that its BOHR (Betavoltaic Orbital High-Reliability) satellite had secured a launch slot on a SpaceX Transporter-17 rideshare mission.

According to reports, SpaceX has scheduled the launch of its Transporter-17 rideshare mission last Tuesday, 7 July. The launch will mark a massive historic milestone. BOHR will be the first-ever nuclear CubeSat to enter orbit.

"This is a historic step for commercial nuclear power in space," said Peter Cabauy, CEO of City Labs. "BOHR demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment. This capability enables persistent, always-on payload operations that are not constrained by sunlight or battery life."

Engineered for safe handling, transportation, and integration into standard commercial launch environments, City Labs’ tritium-based power systems operate at extremely low radiation levels.

BOHR’s core technology is City Labs’ proprietary NanoTritium™ betavoltaic system, which generates continuous power from the natural beta decay of tritium rather than nuclear fission.

Compared to space-bound nuclear reactors, betavoltaic cells operate with no moving parts, no liquid electrolytes, and zero risk of fire or thermal runaway. Furthermore, as the tritium fuel naturally decays, it harmlessly transforms into helium-3, a completely stable and non-radioactive isotope.

Backed by the Department of War, NASA, and the Air Force Research Laboratory, the mission arrives at a key time for space exploration.

NASA’s Artemis program aims to establish a permanent human presence on the Moon. Therefore, the demand for continuous, light-independent power sources is skyrocketing. It could position this satellite as a pathfinder for future deep-space operations.
