His name is Josh Richards. He's a former soldier, a stand-up comedian and a physicist. He's also one of the 100 people shortlisted to be an astronaut candidate for Mars One, the international not-for-profit coalition determined to launch a mission to colonise Mars.

Recently Gizmodo Australia asked Richards about the parallels between exploration and virtual reality, and the Mars One candidate was pretty clear: VR's great, but it's only a piece of the puzzle, not the whole kit and caboodle.
