Critical infrastructure and conflict in outer space: vulnerability, risk reduction and arms control — •Jürgen Scheffran — Institute of Geography, University of Hamburg, Germany

Outer space is considered as part of the critical infrastructures in the civilian and security sector. Satellites conduct numerous tasks, often dual-use, for reconnaissance, early warning, monitoring, weather observation, communication, navigation, environmental protection and research. They support infrastructures on earth, e.g. for the economy and society, energy and resources, political stability and security, health and climate. While space-related activities and investments are increasing, security risks and conflicts are multiplying. The space infrastructure is becoming more vulnerable to multiple risks: interruption of communication by accidents, jamming or ground attacks; collision with other space objects and space debris; physical attack by explosive devices, cyber, nuclear, kinetic or directed energy weapons; sensor blinding; hacking, deception or hijacking. The survivability of space objects can be improved by protection and risk reduction measures, including hardening and shielding, manoeuvring capability, dummies, or active countermeasures. A code of conduct for responsible space behaviour can contribute to confidence-building, rules of the road, risk reduction and stabilization. With the proliferation of space launchers and missiles, missile defense and anti-satellite weapons, threats to space infrastructure would increase, jeopardizing international stability. A space arms race can be avoided through preventive arms control and disarmament, reducing risks to space infrastructure.
