When it comes to the edge of the darkness, the bend in the horizon or the distant stars, humans can't help ourselves: exploration is in our nature. We have climbed to the summits of the earth, peered into the depths of the oceans and planted our feet on the moon. Our primal curiosity has sparked new inventions and revealed the mysteries of the universe.
