A satellite designed to watch how the Sun's breath rattles Earth's magnetic field lifted off from a jungle launchpad in French Guiana at half past midnight local time on 19 May 2026. The Smile mission, a joint project between the European Space Agency and the Chinese Academy of Sciences, rode a Vega-C rocket into orbit on flight VV29. It is the first time these two space powers have built a science satellite together.
A 210 tonne rocket punched a hole in the night sky
The Vega-C rocket stood 35 meters tall on the launch pad and weighed 210 tonnes at liftoff. Its three solid propellant stages fired in sequence to push Smile out of the atmosphere, then a fourth liquid propellant stage took over for a precise drop off around Earth. The launch window opened at 04:52 BST, which was 05:52 CEST and 00:52 local time in French Guiana. The rocket's name, Vega-C, comes from the European family of small launchers designed to carry scientific payloads into low Earth orbit.
Four instruments will watch how the Sun pushes on Earth
Smile stands for Solar wind Magnetosphere Ionosphere Link Explorer. The satellite carries four science instruments that will measure how the solar wind, a constant stream of charged particles from the Sun, interacts with Earth's magnetic field. Scientists want to understand what happens when the solar wind hits the magnetosphere, the invisible bubble that protects the planet. The data will help researchers predict solar storms and geomagnetic storms, which can knock out power grids, disrupt radio communications, and damage satellites.
Why local people in French Guiana cared about a midnight launch
Europe's Spaceport sits near the town of Kourou on the northeastern coast of South America. For residents, a rocket launch is both a spectacle and a source of pride. The Vega C lifted off from a pad surrounded by rainforest, and the bright exhaust lit up the sky for miles. Many locals stayed awake or set alarms to watch the event. The spaceport employs hundreds of people from the region and brings international attention to French Guiana, an overseas department of France.
The Smile mission marks a rare collaboration between Europe and China on a space science project. By studying how Earth responds to the solar wind, the satellite will give scientists a clearer picture of space weather, the conditions in space that affect technology on the ground. The launch was a success, and Smile is now in orbit, ready to begin its work.
