The 2018 European CanSat launch campaign took place from 28 June until 1 July 2018 on the island of Santa Maria, Azores (Portugal). It was hosted by the Regional Fund for Science and Technology (FRCT) in collaboration with local partners. Nineteen teams participated this year: the winners of the CanSat national competitions from Austria, Belgium, Czech Republic, Denmark, Germany, Greece, Ireland, Italy, Nordic (joint competition Finland-Sweden-Norway), Portugal, Poland, Romania, the Netherlands, Spain, and the UK, as well a team from Hungary selected directly by ESA. The European CanSat competition is only one of ESA’s initiatives to help young people increase their literacy and competence in STEM disciplines and inspire them to pursue a career in the STEM (science, technology, engineering, and mathematics) fields.
