It seems that we have run out of undiscovered lands and uncharted oceans. Technology has made the planet accessible. Only the remotest and most hostile places still hide their secrets. Where we cannot go, probes have. Discovery is a channel. Transportation is cheap. We can visit places in high-resolution, in 3D and in virtual reality, before we actually get there.
The Age of Travelling into the Unknown has passed.
Has it? …
… or are there some explorers left?
