A new satellite developed by the **China National Space Administration (CNSA)** and the **Italian Space Agency (ASI)** was launched with the aim of detecting **electromagnetic phenomena** in the ionosphere related to **high-intensity earthquakes and [volcanic eruptions](https://noticiasambientales.com/ciencia/los-glaciares-pueden-prevenir-erupciones-que-dice-la-ciencia/)**.
The device, called **CSES-02 (China Seismo-Electromagnetic Satellite)**, joins the constellation inaugurated in 2018 by **CSES-01**. Together, these satellites will monitor the upper Earth’s atmosphere to identify **possible seismic precursors** and expand the understanding of geophysical processes.
## Advanced Instrumentation for Studying Earth from Space
The CSES-02 is equipped with **eleven scientific instruments**, including:
– A **High-Energy Particle Detector (HEPD-02)**
– An **Electric Field Detector (EFD-02)**
Both were developed in Italy and are designed to study the **flow of energy and matter** between the **Earth’s crust, atmosphere, and ionosphere**, an electrically charged layer that reacts to extreme geophysical events.
## Anticipating Earthquakes: A Scientific Frontier
The **CSES-01** mission had already shown that **acoustic-gravitational waves** generated by earthquakes or eruptions can **reach the ionosphere within minutes**, causing disturbances detectable from space.
Now, with more sensitive instrumentation, the **CSES-02** will seek to detect **weaker and earlier signals**, which could be used as **early indicators** of the onset of major seismic events.
Both satellites orbit at an altitude of about **500 kilometers** and provide **faster and wider global coverage**, ideal for the constant monitoring of natural phenomena.
## Additional Applications: Solar Storms and Cosmic Rays
In addition to its seismic objectives, the constellation will also study:
– Geomagnetic storms
– Cosmic ray flows
– Wave-particle interactions in Earth’s radiation belts
– Ionospheric disturbances linked to astrophysical events, such as gamma-ray bursts
These phenomena, known as **space weather**, affect everything from telecommunications to satellite infrastructure, making their monitoring vital for **global technological security**.
## Space Science in Service of Seismic Prediction
With the launch of **CSES-02**, China and Italy are advancing towards a better understanding of the **processes preceding natural disasters**. This binational project marks a [**milestone in satellite exploration**](https://noticiasambientales.com/medio-ambiente/el-cambio-climatico-amenaza-la-estabilidad-de-los-satelites/) as a tool for the **prevention and mitigation of geological risks** on a global scale.
