This article discusses in a historical and cultural perspective the reasons of an astonishing recurrence of Outer Space in the history of Antarctica. As a spectacular theater of the end of terrestrial geography, Antarctica allowed - with the opening of geography to Outer Space – to establish profound connections with Outer Space. Many analogies were put forward and tested, ranging from psychological studies to logistical and juridical considerations. The domain of fictional literature finally helps to reveal that any parallelism between Antarctica and Outer Space implies a profound auto-referential gesture that is omnipresent in the geographies of Antarctica and Outer Space.
