A Long March 2D rocket lifted off at 3:56 a.m. Eastern (0756 UTC) June 14 from Jiuquan Satellite Launch Center in northwest China. Launch footage showed insulation tiles falling away from the rocket as it climbed into a clear blue sky above the spaceport, with hypergolic exhaust also visible.

The China Aerospace Science and Technology Corporation (CASC) announced launch success within 40 minutes of liftoff, revealing the mission to be carrying the China Seismo-Electromagnetic Satellite-2 (CSES-2), also known as Zhangheng-2, named after a Han dynasty polymath.

Like CSES-1, the satellite will look for correlation between earthquakes and electron flux activity in the inner Van Allen belt.

“The satellite has a design life of six years and carries nine payloads, including an electric field detector developed by China and Italy and a high-energy particle detector developed by Italy,” according to the China National Space Administration (CNSA). Austria is also involved in the mission, with the Space Research Institute of the Austrian Academy of Sciences (IWF) providing a scalar magnetometer.

CSES-2 will monitor global electromagnetic fields, ionospheric and atmospheric conditions in near real-time, and detect electromagnetic anomalies linked to geological or human activities, as well as thunderstorm and lightning events. CSES-2 aims to enhance China’s early warning and risk assessment capabilities, and monitoring of natural disasters such as earthquakes, tsunamis, volcanic eruptions and severe storms.
