Educational and scientific missions are inspiring alternatives for conventional learning. They become more and more professional platform to perform space studies, with a wide range of opportunities for development of a new technologies. They act as an incubator for innovative science, were science fiction is transformed into reality. Participants can use their imagination and creativity without limits and use it as trampoline to jump directly into professional space projects. This is what we observe in AATC. Analog missions motivate to write publications in relevant scientific journals and popular science media. They bring valuable experience and training dedicated to work in space sector.
