This article examines cybersecurity within the European Union's Space Programme, with a focus on Germany's proactive approach. As space-based assets become increasingly vital for essential services, cybersecurity in space has emerged as a universal imperative. The central research question addressed is: “What strategies does Germany employ to enhance cybersecurity in the EU space sector, and how do these strategies balance national and collective security interests?". Germany's strategies in cybersecurity, public-private collaboration, and supply chain security are analysed, highlighting its efforts to fortify cosmic frontiers and enhance European cyber resilience. Germany's Federal Space Strategy demonstrates the country’s commitment to balancing national autonomy with collective security, while technical initiatives led by the Federal Office for Information Security (BSI) showcase adaptability in addressing evolving cyber threats. In this context, the article also discusses the challenges and potentials of a coordinated EU-wide approach versus individual member state strategies in enhancing space cybersecurity. Through a balanced discussion, the article explores how Germany's approach offers insights for shaping future cybersecurity policies for the space sector at both national and EU-wide levels. By navigating the complexities of space cybersecurity while balancing autonomy and cooperation, Germany emerges as a pivotal case study, offering valuable lessons for addressing global vulnerabilities and shaping the future of space security.
