ITACUBE is an Instituto Tecnológico de Aeronáutica student initiative for educational CubeSat-format platforms and scientific balloon experiments. It grew from 2021 aerospace-engineering course projects and became a student technical initiative in 2023. Its platform portfolio distinguishes CURIESAT, a radiation-measurement and training prototype associated with the second OBSAT competition, from Casimiro, a follow-on platform adding imaging objectives for INPE’s Cubesign challenge. The program emphasizes roughly year-long projects, practical integration and knowledge exchange with faculty and engineers.
