Ctrl+Space CTF Quals

Ctrl+Space CTF is the first European in-orbit Capture the Flag competition. The event is a joint collaboration between the European Space Agency (ESA), D-Orbit, and the mhackeroni team, who are also responsible for creating the challenges. The competition consists of an online qualification round featuring space-themed jeopardy-style tasks, followed by an on-site final held during the Security for Space Systems (3S) Conference, taking place at ESTEC in the Netherlands from 4 to 6 November 2025. Finalists will face real-time security challenges executed directly aboard D-Orbit’s ION Satellite Carrier, orbiting Earth in real time. Ctrl+Space CTF is supported by the ESA Security Office and the ESA Security Cyber Centre of Excellence (SCCoE). Join the discord: https://discord.gg/pkcCP34GPE
