Last year I visited some far off countries and was helped along the way by some Lonely Planet guide books. One thing I thought of one night in New Zealand was the idea of a Lonely Planet guidebook for Mars. OK, Mars doesn't have much in the way of night life or restaurants but it definitely has some potential tourist attractions and amazing sights to see. My plan feels as though it is a step closer now that the European Space Agency's Mars Express has released the first "hiking maps" of Mars. They aren't quite up to the standards of a good Ordnance Survey map yet and they are only on a scale of 1:200,000 wtihout many contours shown, so I won't be using them to plan a walking route just yet. It is a good start though.
