United States launches first commercial nuclear-powered satellite
Tap title to read story
SpaceX has launched the world’s first commercial satellite using nuclear technology for power, marking a significant milestone for space-based energy systems. The Falcon 9 rocket lifted off from Vandenberg Space Force Base in California on July 8, 2026, as part of the Transporter-17 rideshare mission, carrying 81 payloads into orbit. The primary payload, a CubeSat named BOHR, was developed by Florida-based City Labs and carries the company’s NanoTritium betavoltaic power system. While the satellite’s main operations still rely on solar panels, the mission is the first in-orbit test of City Labs’ betavoltaic system and the first commercial satellite with Federal Aviation Administration approval for a nuclear launch.
