CSES (China Seismo-Electromagnetic Satellite) scientific space missions are dedicated: to monitoring electromagnetic field and waves, plasma and particle perturbations of the atmosphere, ionosphere and magnetosphere induced by natural sources and anthropocentric emitters and to study their correlations with the occurrence of seismic events. They investigate the structure and the dynamic of the topside ionosphere, the coupling mechanisms with the lower and higher plasma layers and the temporal variations of the geomagnetic field, in quiet and disturbed conditions. Data collected during the missions also allow to study solar-terrestrial interactions and solar physics phenomena, namely Coronal Mass Ejections (CMEs), solar flares and cosmic ray solar modulation. The data will contribute to provide an observational sharing service for international cooperation and the scientific community.
The program foresees several satellites to be sequentially launched. Currently, CSES-01 satellite is in orbit since February 2nd, 2018 equipped with nine instruments, among them the Italian High Energy Particle Detector (HEPD-01). Expected lifetime is 5 years.
CSES-02 satellite is in advanced implementation stage and equipped with ten instruments: among them the Italian High Energy Particle Detector (HEPD-02) and Electric Field Detector (EFD). The launch is scheduled by March 2022. Expected lifetime is 6 years.
CSES missions are part of a collaboration program between China National Space Administration (CNSA) and Italian Space Agency (ASI), and developed by China Earthquake Administration (CEA) and Italian National Institute for Nuclear Physics (INFN), together with several Chinese and Italian Universities and research Institutes. Two missions, CSES-01, currently in orbit, and CSES-02, in implementation stage, constitute the first phase of the program.
Italy participates to the CSES missions with the LIMADOU project - funded by ASI and INFN - through a collaboration that includes several INFN Divisions (Bologna, Naples, Roma Tor Vergata, Torino), the INFN Center TIFPA of Trento, the INFN National Laboratories of Frascati, the Universities of Bologna, Roma Tor Vergata, Torino, Trento, Uninettuno, INAF-IAPS (Institute for Space Astrophysics and Planetology), INGV (Institute National Institute of Geophysics and Volcanology), CNR-IFAC (Institute of Applied Physics).
