Over two days, this workshop, organised together with the German Wargaming Center, uses wargaming to explore society’s deep dependence on space. The focus lies on the reliance of economies, critical infrastructures, and armed forces on satellite services for timing and synchronisation, navigation, and communication. On the first day, experts from the German Space Command, the Bundeswehr’s Cyber and Information Domain Service, ESPI, and other institutions will provide insights into threats to these services and ways to protect them, before participants are assigned to their teams. On the second day, the teams will play through a scenario in which these services come under pressure, forcing decisions under uncertainty and time constraints. A thorough debriefing will conclude the workshop, reflecting on the dilemmas encountered and the lessons for European resilience in space.
