Gathering around a satellite image: Visual media cycles of the nuclear nonproliferation complex

How have Western nongovernmental experts used remote sensing to make public knowledge about Iran's nuclear program? This article recounts several episodes in which experts and journalists congregated around satellite images to uncover hidden nuclear objects in Iran. Drawing from the theoretical tradition of co-production, I describe this recurrent collective experience as an <i>imaginative exercise</i> that can both coordinate and transform diverse communities of knowledge. I outline common temporal and thematic structures that define these episodes, and illuminate the role of commercial satellite imagery as material anchor that threads distributed imaginings together such that broadly-shared experience and sensibility can emerge. I argue that these collective imaginative practices have fomented civic-epistemic closure, not around affirmative nuclear facts or beliefs about Iran, but around a set of persistent questions about the 'possible military dimensions' of its nuclear past. I close by exploring the broader political effects of this form of recursive inquiry within the global nuclear order.
