SMILE Launches on Vega C for 3-Year Mission as Europe-China Science Ties Tighten
11 articles · Updated · spacedaily.com · May 19
SMILE lifted off from Kourou on a Vega C rocket and separated into orbit within an hour, starting a three-year mission to study how Earth’s magnetic shield reacts to solar wind.
Four instruments — led by a Soft X-ray Imager using lobster-eye optics — aim to deliver the first wide-field images of the magnetopause, letting scientists watch the boundary shift instead of inferring it from point measurements.
Multiple engine burns will now raise the spacecraft into a highly elliptical polar orbit, where long views over the North Pole should enable sustained imaging of the dayside magnetopause and auroral oval.
ESA supplies the payload and data downlink while the Chinese Academy of Sciences provides the spacecraft platform, making SMILE a rare high-profile joint mission as Europe grows more cautious about research cooperation with China.
Vega C also gains from the flight: after its 2022 failure and return to service, a successful science mission supports Avio’s push to rebuild confidence and carve out a steadier commercial role for the rocket.

SMILE Satellite Launch: ESA-China Partnership Opens New Era in Space Weather Science
Overview
The SMILE mission, launching on May 19, 2026, marks a major step in international space collaboration and scientific discovery. By opening a new window into Earth's magnetic shield, which protects us from the Sun's powerful radiation, SMILE aims to revolutionize our understanding of space weather and its effects on our planet. The mission will be launched from Europe’s Spaceport in French Guiana using a Vega-C rocket. This collaborative effort promises to provide unprecedented insights into how Earth's magnetic shield works, setting the stage for improved space weather forecasting and greater protection for our technology and infrastructure.
