However, as geopolitical rivalries re-emerge in more traditional domains of interstate conflict, the prospects for future stability in space appear increasingly dim. While the consequences of a great-power clash in space could be ruinous, a shared understanding of the perils in- volved has yet to take hold. Strategic interaction along the ‘final frontier’ is set to enter a period of considerable danger.
