Adam Clarke Estes has posted on Gizmodo this interactive map of Ganymede, one of Jupiter’s moons, which also happens to be the largest moon in our corner of the universe. Ganymede is an extra special Jovian satellite because it has an underground ocean and is one of our solar system’s few potentially habitable environments. In the words of Mr Clarke Estes:

The map is a little intimidating at first, but once you delve into it, you’ll realize that exploring the geography of Ganymede isn’t so different from exploring the geography of Earth. Different colors represent the different elements that make up the moon’s surface creating an almost marbled look as the minerals run together. Of course, Ganymede would need a little work before we can colonize it. But let’s just hope we never have to.

So instead of Mars, should NASA or SpaceX be planning a mission for the Moon of Ganymede instead?
