China and Europe Just Launched a Historic Joint Solar Science Mission
The SMILE space mission has successfully launched on a mission to better understand space weather and how the Earth is protected from the Sun. This marks the first time the European Space Agency (ESA) and the Chinese Academy of Sciences have jointly designed, operated, and launched a mission. CGTN’s Wu Lei spoke to some of the Chinese scientists involved.
The European Space Agency-China SMILE satellite launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on at 04:52 BST / 05:52 CEST (00:52 local time) on May 19, 2026.
SMILE will use four science instruments to study how Earth responds to the solar wind from the Sun. In doing so, SMILE will improve our understanding of solar storms, geomagnetic storms and the science of space weather.
The European Space Agency (ESA) is responsible for providing SMILE’s payload module (carrying three of the four science instruments), one of the spacecraft’s four science instruments (the soft X-ray imager, SXI), the launcher, and the Assembly Integration and Testing facilities and services. ESA contributes to a second science instrument (the ultraviolet imager, UVI) and the mission operations once SMILE is in orbit.
The Chinese Academy of Sciences provides the other three science instruments and the spacecraft platform, and is responsible for operating the spacecraft in orbit.
Duration: 2 minutes
