Terrains

Eleven very different places to stand. On Earth: a steaming rainforest, a sea of dunes, a river of ice, fresh lava, a coral island, the open ocean and the Serengeti. Beyond it: the grey dust of the Moon, the red plains of Mars, the cracked ice of Europa and the cloud tops of a planet with no ground at all. Read how each one works, then land there and look around in 3D.
