Space has serious implications for national security, given our global dependence on over 1,900 satellites (and other space systems) to inform Defence and intelligence. Space systems are dependent on cyber and therefore vulnerable to a wide array of threats such as attacks and jamming. There are also significant multi-disciplinary challenges such as the increasing adverse impact of space debris on capability; the pressing need for international regulatory frameworks; and the emerging impact of commercial activities such as mining. Improve your space situation awareness and the issues, risks and challenges for the national security community.
