China successfully launched the Zhangheng 1B satellite at 3:56 pm, placing it into its intended orbit. This mission enhances China's capabilities in observing and responding to natural disasters from space and monitors Earth's geophysical fields.
The Zhangheng 1B satellite is a collaboration between China and Italy, stemming from a 2019 memorandum of understanding. It is equipped with nine scientific instruments, including an electric field detector developed jointly by the two countries. Italy also contributed a high-energy particle detector. The satellite is designed to operate for six years.
The primary objective is to provide near real-time measurements of global electromagnetic fields, electromagnetic waves, the ionosphere, and the neutral atmosphere. It will also detect electromagnetic irregularities linked to geological and human activities, and collect data on atmospheric lightning and thunderstorms. This data will improve disaster early warning systems.
The system aims to improve China's ability to detect and analyze risks associated with events such as earthquakes, volcanic eruptions, tsunamis, and severe storms. Furthermore, Zhangheng 1B will contribute valuable data for emergency response planning, resource mapping, and support for communication and navigation systems, helping China better prepare for and respond to natural disasters.
This new satellite builds on the success of Zhangheng 1A, launched in 2018 and still operating. While Zhangheng 1A focuses on earthquake-related phenomena, Zhangheng 1B utilizes upgraded payloads and a wider sensing range. Both satellites now operate in coordinated phases, improving observational resolution and effectiveness.
