The Final Frontier Part 3: How to Scratch an Itch in Space, the Surprisingly Long Time You Can Survive in Space Without a Spacesuit, Why the Apollo 13 Astronauts Got Cold, and Much, Much More


In this episode of The Brain Food Show, we begin by following up on a previous discussion on Daimler and what exactly a little girl named Mercedes had to do with things. We then jump into the surprisingly oft’ requested follow up on Simon’s first ranch dressing experience.

Next up we move into the meat of the episode, discussing how astronauts scratch an itch in their space suits, followed by looking at the surprisingly long time you can survive in space without a space suit or any other protection, with no long term damage.

During that discussion we get side tracked talking about why the Apollo 13 crew got so cold on their trip when space is not cold at all, but rather a great insulator, and why they didn’t simply put on their space suits to keep warm.

We then discuss at length the amazingly fascinating way in which airline planes get oxygen to passengers when there is no central oxygen store aboard the plane, outside of the pilot’s emergency supply. Then we look at the equally interesting way in which they get oxygen to passengers when there is a loss of cabin pressure- again, given there is no central oxygen store aboard the plane for passengers.

On another note, if you could do us a huge favor and rate and review this show in whatever podcasting platform you’re using (including hopefully giving us some feedback related to the new format), we would be extremely grateful. Thanks!
