From 6 to 24 June 2026, students from the ALEASAT team from the University of British Columbia and Simon Fraser University, Canada, conducted an extensive environmental test campaign at the CubeSat Support Facility, at ESA ESEC Galaxia, Belgium, as part of ESA’s Fly Your Satellite! programme. Over three weeks, the team conducted vibration, thermal-vacuum, thermal balance and functional tests on ALEASAT subsystems and its spacecraft model. The campaign provided valuable hands-on experience, generated data to improve design and simulation models, and marked an important step towards future qualification testing.
