Zhangheng 1-02, also known as CSES-02 (China Seismo-Electromagnetic Satellite-02), is the follow-on mission to Zhangheng 1/CSES, a Chinese–Italian space mission dedicated to monitoring the electromagnetic field and waves, plasma parameters, and particle fluxes induced by natural sources and artificial emitters in near-Earth space, to study their correlations with the occurrence of seismic events. The satellite mission is part of a collaboration program between the CNSA (China National Space Administration) and ASI (Italian Space Agency), and developed by CEA (China Earthquake Administration) and INFN (Italian National Institute for Nuclear Physics), together with several Chinese and Italian Universities and research Institutes.
ZHANGHENG 1-02 was lifted into orbit during the mission ‘Long March 2D | Zhangheng-1-02’, on board a Long March 2D space rocket.
The launch took place on June 14, 2025, 7:56 a.m. from Launch Area 4 (SLS-2 / 603).
