The “Summer School Alpbach” has been succesfully completed. It took place in Alpbach, Austria, between July 9-18, and among 60 selected participants there were two students from Greece, whose participation was financially supported by the HSC: Georgia Moutsiana (PhD fellow, UOA Department of Physics) and Christos Dinos (PhD fellow at IPGP, France). The School topic was “Moons of the Giant Planets”. The participants had an in-depth learning experience, attending engaging lectures on aspects of space science and engineering, and worked intensively in four teams to define and plan a space mission under the supervision of important scientists and engineers.
