In light of the recent Spaceship 2 disaster, Phil and Stephen discuss the past and future of space toursim. The discovery of the oldest map of the cosmos is a reminder that we have been pursuing the great Out There for a very long time. Some are now asking whether space tourism can survive. Have we reached the end, or have we even made it to the beginning yet?
PLUS: Who is really going to steal your job? (Maybe not a robot.)
And on a completely unrelated topic (or is it?) can you ever really know an extraterrestrial?
Bonus topic, time permitting: Do we need more big data hype?
