For the science buff who has everything, including numerous globes of the Earth from different periods in history, how about a globe that's literally out of this world? By that we mean Mars. The Greaves and Thomas Mars Globe is a 30 cm globe that uses the latest NASA imagery to provide a high-quality representation of the surface of Mars. It also includes accurate place names and the locations of the latest Mars landers. Keep this globe handy, and you'll never be lost on Mars (maybe we should give one to the U.K. Beagle team - ooh, harsh).
