Welcome to the official home of PADRE (The Solar Polarization and Directivity X-Ray Experiment), a groundbreaking NASA CubeSat mission poised to revolutionize our understanding of solar flares. As a 12U solar spinner CubeSat, PADRE focuses on measuring the polarization and directivity of hard X-rays (HXRs) emitted during flares, unraveling the behaviors and distributions of high-energy electrons in the Sun’s atmosphere. Developed on a cutting-edge EnduroSat CubeSat platform, PADRE combines advanced instrumentation with a robust, cost-effective design—paving the way for a new era of agile space exploration. Join us as we push the boundaries of solar physics research and unlock the secrets of our closest star.
