I went to a book event tonight at which a friend and his co-authors talked about their latest book - Great Expeditions - 50 journeys that changed our world. It prompted me to ask:
What remains to be done as a Great expedition or journey?
Into the mind & Time travel were two of my thoughts. What are yours?

In reply to keith-ratcliffe:


Solo journey round the whole Solar System, landing on all the planets and moons. I wish. I'd go like a shot.

Much of our oceans remain unexplored.
