Miami-based City Labs successfully launched its Betavoltaic Orbital High-Reliability (BOHR) satellite on a SpaceX rideshare mission, marking a significant advancement for commercial nuclear power in space. The BOHR satellite, a "1U" Cube Sat roughly the size of a softball, utilizes a nuclear betavoltaic battery powered by the decay of tritium to generate electricity.

This launch represents a crucial first step toward more ambitious space nuclear applications, such as powering permanent lunar bases or enabling efficient deep-space propulsion. While BOHR itself uses conventional solar power for primary operations, its betavoltaic battery serves as a demonstration of a compact, regulatory-approved nuclear power source ready for commercial deployment. City Labs CEO Peter Cabauy stated this technology enables persistent, always-on payload operations independent of sunlight or battery limitations.

Betavoltaic batteries are ideal for low-power, long-duration applications requiring reliable electricity, including remote terrestrial sensors and secure communication instrumentation. City Labs is also exploring this technology for implantable medical devices, indicating a broader potential impact beyond space exploration.
