Last night I was catching up on some items I had saved in my DVR, but I had not watched yet. One was an episode of PBS Independent Lens called Space: The Longest Goodbye. It is about how NASA has attempted to research how we humans might approach a trip to Mars as the journey is long and people who volunteer to go will experience extreme isolation.
The program was a little dry at first, but became more interesting towards the second half. When it comes to space exploration, people are focused on things like "science", technology and biology.....but are humans prepared to mentally survive? NASA hired psychologists to look into just that.
