Common public narratives about mitigating catastrophic or existential risks to humanity require technological progress, as well as the assumption that the investors and makers of those technologies will also envision and govern how they are used. However, singular innovations and technocratic governance are rarely a match for the complex systems that will create and deescalate global catastrophe. This article uses examples from space technology to argue that it is possible to allow technology to have an important role in that future, without advocating technology as a universal solution, or that those with technical know-how should lead the frontier of human development. This involves developing governance that does more work to reflect the complexity of the planet it makes decisions about. It also involves confronting the immaturity of human decision-making, and avoiding the colonising behaviours that have reappeared in today’s space entrepreneurs. This chapter ends with a sketch of how to develop policy for how space technology could better serve sustainable development goals in order to illustrate a model of governance that rests on more inclusive participation in imagining and realising futures.
