World's First Commercial Nuclear-Powered Satellite Reaches Orbit SpaceX's Transporter-17 rideshare mission carried City Labs' BOHR CubeSat to orbit on July 7, the first commercially built satellite to fly a nuclear-powered payload — a tritium betavoltaic cell that generates electricity continuously, day or night, regardless of sunlight. Key points • Launched July 7, 2026 at 3:12am EDT from Vandenberg Space Force Base aboard a Falcon 9, part of the 81-payload Transporter-17 rideshare mission. • BOHR (Betavoltaic Orbital High-Reliability) CubeSat built by City Labs, a Miami/Florida-based company. • Uses a 'NanoTritium' betavoltaic device — converts beta particles from the radioactive decay of tritium directly into electricity via a semiconductor. • Power output is tiny (micro-to-milliwatt range) but continuous — unaffected by eclipse periods or solar panel orientation. • Tritium's 12.3-year half-life means the power source stays effective for two decades before decaying to harmless helium-3. • FAA authorised the launch after finding public radiation exposure would stay below one millirem under conservative assumptions. 2. New Zealand's Fuel-Free Thruster Passes First Orbital Test Auckland-based Zenno Astronautics has successfully tested its 'Supertorquer' — an attitude-control thruster that uses superconducting magnets to push against Earth's own magnetic field, generating thrust with no propellant at all. Key points • Zenno Astronautics is a spin-off from the University of Auckland, New Zealand. • The system, called 'Supertorquer', completed its first in-orbit test in early July 2026. • Superconducting magnets, powered by solar panels, interact with Earth's magnetic field to generate torque and maintain a satellite'…","meta_description":"Astronomy Daily — S05E135 — Wednesday, July 8, 2026 1.
