CanSat 2025 celebrated three brilliant teams from Brussels, Wallonia, and Flanders!

The CanSat Belgium competition, funded by Innoviris, invites 5th and 6th year secondary school students each year to imagine, build, and launch a mini-satellite the size of a 33 cl soda can.

As the name "CanSat" suggests, it’s all about satellites. All teams share a common mandatory mission: to collect atmospheric data (temperature, pressure, and altitude), transmit it in real time to a ground station during the rocket launch, and then land safely using a purpose-built parachute.

Throughout the school year, the CanSat project goes through various selection stages. It’s a thrilling technical and scientific challenge that immerses young people in the world of space exploration.

In Wallonia, the "Vigilance" team from Institut Notre-Dame in Arlon stood out with its innovative project on early fire detection and prediction, impressing the jury with its relevance. In Brussels, the Husarz team from the European School Brussels I was recognized for its CanSat equipped with three clever fins designed to control descent speed. In Flanders, the spotlight was on Athénée Royal (K.A.) of Beveren, which shone with its “Filter Flyers” project, using a Kalman filter to accurately predict the satellite's landing area.

“Filter Flyers” was also crowned the overall winner of the 2025 edition and will represent Belgium at the European final organized by the ESA at Estec, in the Netherlands. All the winning teams will have the opportunity to take part in an aerospace discovery trip to Madrid this summer.

CanSat is much more than a competition: it’s a remarkable educational adventure that sparks scientific vocations and stimulates innovation from a young age.

Each year, this scientific competition is organized in collaboration between the Walloon Region (SPW EER), the Flemish Region (Vlaio), and the Brussels-Capital Region (Innoviris), as part of the European programme of the European Space Agency (ESA). The initiative promotes STEM (Science, Technology, Engineering, and Mathematics) among young people, with a practical application of science and technology in the field of space, where collaboration and creativity play a key role in the success of their project.
