The solar PolArization and Directivity X-Ray Experiment (PADRE) is NASA CubeSat mission to study and decipher the secrets of the Sun. The mission is a collaboration between the Space Sciences Laboratory – University of California Berkeley (SSL/UCB), Goddard Space Flight Center (GSFC), Southwest Research Institute (SWRI), University of Applied Sciences and Arts Northwestern Switzerland (FHNW), the Saclay Nuclear Research Centre of the Commissariat à l’énergie atomique (CEA-Saclay).
The science instruments (x-ray polarimeter and Directivity sensor) will be hosted on EnduroSat’s 12U satellite and are scheduled to launch in 2025. This will enable observation of the Sun in hard X-rays (HXRs) from LEO to determine the angular distribution of accelerated electrons from standalone and joint SOLO/STIX observations. This will allow the determination of the angular distribution of flare-accelerated electrons, a quantity that is currently unknown, except in a handful of ambiguous cases.
PADRE Mission will help humanity understand better solar activity, solar flares, and space weather. The most challenging and interesting aspect of this mission is that EnduroSat’s 12U satellite will be spinning at a constant rate while taking measurements. The platform is one of the highest-performance platforms of the company, easily adaptable to handle complex Earth Observation, IoT, science, and exploration missions.
The PADRE mission poses some unique challenges for Cubesats and Endurosat’s adaptable design allows us to optimize the satellite to answer long outstanding questions in heliophysi

We are proud and excited to support visionary exploration missions. PADRE will uncover the mysteries of the Sun, providing new insights into previously unavailable solar flare acceleration models. We are enthusiastic about the future!

Today’s announcement follows a period of rapid growth for EnduroSat which closed a US$10m Series A in May, led by the EU Private Equity CEECAT Capital which is focused on the high-growth markets in CEE region. Existing investors including Freigeist Capital also joined the round. EnduroSat’s Balkan Constellation was recently selected by ESA and the EU for the Copernicus Contributing missions. The constellation will provide the Balkans and the EU with unprecedented revisit time, real-time cloud-based monitoring services, and AI-powered detection. It will accelerate access to maritime surveillance, humanitarian, and ecological support, as well as environmental monitoring.
