The extraterrestrial Earth: Antarctica as analogue for space exploration

The polar regions have often been suggested as surrogates for the exploration and colonization of space. In particular, Antarctica's greater isolation makes it a useful analogue. Its features-abiotic, acultural, alien to human habitation-all echo the regions of interest to contemporary exploration, notably the solar system and the deep oceans. But more than a century of Antarctic experience also suggests that exploration will likely resemble the Renaissance's Great Voyages and their outposts rather than become portals for wholesale colonization. These sites will traffic mostly in information-the spices and luxury goods of interest to their sustaining societies.
