Space security has become an increasingly salient policy issue. Over the last several years, there has been growing concern from multiple governments over the reliance on vulnerable space capabilities for national security, and the corresponding proliferation of offensive counterspace capabilities that could be used to disrupt, deny, degrade, or destroy space systems. This in turn has led to increased rhetoric from some countries about the need to prepare for future conflicts on Earth to extend into space, and calls from some corners to increase the development of offensive counterspace capabilities and put in place more aggressive policies and postures.

We feel strongly that a more open and public debate on these issues is urgently needed. Space is not the sole domain of militaries and intelligence services. Our global society and economy is increasingly dependent on space capabilities, and a future conflict in space could have massive, long-term negative repercussions that are felt here on Earth. Even testing of these capabilities could have long-lasting negative repercussions for the space environment, and all who operate there. The public should be as aware of the developing threats and risks of different policy options as would be the case for other national security issues in the air, land, and sea domains.
