Astronauts go to space. Space tourists go to space. So... What's the difference? Kovi and Benjamin have a conversation this episode about when space travel switched from only sending the best of the best military trained and/or highly science educated into space to just sending anyone who could afford a ticket. A space traveler was once a young, healthy, heavily trained person who's been pushed to the physical limits in preparation for a solo flight. Nowadays anyone can go, old or young, as part of a crew just for the fun of it. Will Shatner's overview effect was a beautiful thing to watch, and so long and thanks for all the fish.
