Florida Company Demonstrates Alternative Space Power System

A Florida startup, City Labs, has launched a cubesat to test a nuclear-powered satellite technology, which could allow future spacecraft to operate for years without relying on solar panels or conventional batteries. The BOHR cubesat, launched aboard SpaceX’s Transporter-17 mission, is designed to demonstrate the company’s NanoTritium betavoltaic power system, which generates electricity from radioactive decay. The mission is partially funded by NASA and Pentagon contracts, reflecting government interest in alternative space power systems. This development was first reported by SpaceNews.
