This annual four-week programme in July/August is targeted at university students and young engineers from the aerospace industry. It covers various aspects of space, in particular space transportation, and includes classes, lectures and tours of firms and space agencies, as well as language tuition and cultural and leisure events. The Summer School is hosted by educational institutions and supported by agencies, industrial firms and local sponsors. During this time, alumni of previous sessions meet up for a space-based weekend which takes in cultural visits.
