This autonomous, solar-powered robot carries a ground-penetrating radar to study how snow accumulates, adding layer upon layer to the ice sheet over time.
Scientists are keen to study Antarctica's subglacial hydrological systems because liquid water beneath the ice sheet will influence its movement (the ice above Lake Whillans is moving at about 300m per year).
Among the most striking of the architectural drawings on display is the study for the plan of San Giovanni dei Fiorentini (1559-60), a sheet in which one can read the layers of overdrawing and erasure through which Michelangelo refined his design, transforming the sheet into a palimpsest of rejected ideas.
