China expanded its space-based disaster detection system on Saturday. Notably, the Zhangheng satellite boosts disaster monitoring efforts by enhancing electromagnetic field observations. A Long March-2D rocket carried the satellite into orbit from Jiuquan at 3:56 p.m. Beijing time. According to officials, the China National Space Administration (CNSA) confirmed the satellite entered its planned orbit. It marks a major step in China’s space-based disaster risk infrastructure.
The new satellite builds on the legacy of Zhang Heng, who invented a seismoscope over 1,800 years ago. Specifically, named Zhangheng 1-02, it is the second satellite in the series. China and Italy jointly developed it under a long-term civil space cooperation plan. It carries nine scientific payloads, including an electric field detector and a high-energy particle detector. Moreover, scientists expect it to operate for six years.
Importantly, the Zhangheng satellite boosts disaster monitoring efforts by collecting real-time electromagnetic data. It tracks electromagnetic waves, ionospheric activity, and atmospheric conditions. In addition, this includes signals caused by natural and human-made disturbances. The satellite will also observe lightning and thunderstorm patterns around the world. As a result, these capabilities will help predict disasters such as earthquakes, tsunamis, and volcanic eruptions.
The CNSA said researchers will study changes in Earth’s physical fields using the satellite’s data. Consequently, this research could improve forecasts of extreme weather and space-related events. Furthermore, Peng Wei from the CNSA emphasized the mission’s role in boosting early warning systems. He also noted the importance of improving risk assessment and emergency response. Therefore, the Zhangheng satellite boosts disaster monitoring efforts in critical ways.
Alongside its scientific mission, the satellite promotes international cooperation. Italy played a key role in the mission’s payload design and data research. Francesco Longo of the Italian Space Agency called the mission a milestone. He said the satellite’s success shows the strength of Sino-Italian space collaboration. Italy named its part of the project Limadou, honoring the legacy of Matteo Ricci.
Saturday’s launch was the 581st for the Long March rocket family. The first Zhangheng satellite, launched in 2018, remains fully operational. The two will now work together to increase monitoring accuracy and resolution. By combining observations, they will improve coverage across time and space. Together, they aim to safeguard lives and strengthen scientific understanding.
