CESAR PROJECT

CESAR (Cooperation through Education in Science and Astronomy Research) is an educational program developed by the European Space Agency (ESA), the National Institute for Aerospace Technology (INTA), and Systems Engineering for Defense of Spain (ISDEFE). Its main goal is to bring space closer to classrooms, making use of the enormous potential of scientific data and the professional expertise of the entities involved in the project. We provide educational scientific resources and experiences that promote interest in astronomy and space, as well as future scientific careers, prioritizing diversity and inclusion for all people.
