The NUSES mission is a groundbreaking space initiative aimed at testing and advancing innovative
technologies and observation techniques. NUSES seeks to explore cosmic radiation, astrophysical
neutrinos, the Sun-Earth environment, space weather, and magnetosphere-ionosphere-lithosphere
coupling (MILC) phenomena. The satellite will carry two state-of-the-art payloads: Terzina and
Ziré. Terzina is a compact optical instrument featuring a Cherenkov telescope and advanced
Silicon Photomultipliers (SiPMs) to study the background induced by high-energy protons. Ziré
will provide precise measurements of particles and gamma rays, offering valuable data on cosmic
rays and potential MILC events. This paper presents an overview of the NUSES satellite’s
instrumentation and discusses the scientific and technological goals of this pioneering mission.
