“张衡一号”02星成功发射 天上的卫星和地震是如何联系上的？

Core Viewpoint - The successful launch of the "Zhang Heng-1" 02 satellite marks a significant advancement in China's capabilities for geophysical field observation, contributing to the country's space infrastructure development [1][2]. Group 1: Satellite Overview - The "Zhang Heng-1" 02 satellite is the first geophysical field exploration satellite in China's medium- and long-term development plan for civil space infrastructure, designed for a lifespan of 6 years and equipped with 9 scientific detection devices, including an electric field detector [2][6]. - This satellite is an upgraded version of the "Zhang Heng-1" 01 satellite, which primarily served as a research satellite to validate relevant technologies, while the 02 satellite is intended for practical business applications [6][10]. Group 2: Scientific Objectives - The satellite aims to monitor global electromagnetic fields, electromagnetic waves, ionosphere, and neutral atmosphere parameters in near real-time, which are crucial for understanding geological activities and extreme weather [4][8]. - The "Zhang Heng-1" series satellites can capture electromagnetic waves released during geological activities, providing data for earthquake precursor research by analyzing the temporal and spatial correlations with seismic events [8][10]. Group 3: International Collaboration - The "Zhang Heng-1" 02 satellite is a product of collaboration between China and Italy, enhancing the monitoring capabilities for seismic electromagnetic precursors and addressing disaster prevention and mitigation needs globally [11][12]. - The cooperation includes shared responsibilities, with China focusing on satellite development and launch, while Italy leads the development of specific detection instruments [12][14]. Group 4: Historical Context - The collaboration between China and Italy in space exploration dates back to 1991, with various agreements signed to promote peaceful use and research in outer space, culminating in the successful launch of the "Zhang Heng-1" 01 satellite in 2018 [14].
