Swiss-Built Smile Satellite Successfully Launches Into Space

The Smile satellite has successfully launched into space, marking a major achievement for Swiss and international space research.

A Vega-C rocket carried the satellite to an altitude of more than 700 kilometres above Earth before the spacecraft safely separated and deployed its solar panels. Scientists confirmed the mission’s successful start shortly after launch.

Researchers from the University of Applied Sciences and Arts Northwestern Switzerland played a key role in developing important components for the mission. Project leader Säm Krucker described the launch as an exciting milestone and said the satellite will now begin collecting scientific data over the next three years.

The Smile mission is a joint project between European and Chinese space agencies. Its primary goal is to better understand space weather and the interaction between solar winds and Earth’s magnetic field.

Space weather is caused by charged particles released from the Sun during solar storms. When these particles collide with Earth’s magnetic field, they can create auroras while also disrupting satellites, navigation systems, communications, and even power grids.

Swiss researchers developed and tested a cooling system for the satellite’s telescope and also contributed advanced software algorithms designed to improve image quality captured by the onboard wide-angle camera.

Swiss technology also supported the rocket itself. Beyond Gravity manufactured the rocket’s protective nose cone, which shielded the satellite during launch.

The successful mission highlights Switzerland’s growing role in global aerospace innovation and scientific space exploration.
