The NUSES space mission is built around two complementary scientific payloads: Ziré and Terzina. Ziré is dedicated to the observation of low-energy cosmic rays and gamma rays, the monitoring of Sun-Earth interactions, and the investigation of space weather and geophysical coupling phenomena (Magnetosphere-Ionosphere-Lithosphere). It includes a dedicated Low Energy Module (LEM) that extends its sensitivity down to the MeV energy range for charged particles. Terzina, on the other hand, is a pathfinder for orbit-based detection of atmospheric Cherenkov light, with the goal of exploring ultra-high-energy cosmic rays (UHECRs) and advancing neutrino astronomy from space. Both payloads rely on a modular and scalable readout architecture that leverages Commercial Off-The-Shelf (COTS) components, including custom DAQ boards and concentrator units managing over 1800 Silicon Photomultiplier (SiPM) channels. The system integrates Citiroc ASICs, low-power FPGAs, and Zynq Ultrascale+ SoCs, enabling real-time event classification via onboard neural network inference. This architecture combines high density, low power, and resilience, offering a scalable solution for advanced future space missions.
