Never explore the final frontier without your trusty, white, puffy space suit! But why is it puffy and white? And why do astronauts need them? Turns out space is super dangerous and these suits can save your life.

We’ll give you a tour of all the features of NASA’s iconic EMU suit and explain why it looks like a squishy marshmallow. Plus, we’ll interview an engineer working on the next generation of space suits and hear a funky new space jam by singer Jamie Lidell.

Add in a mystery sound, a Moment of Um looking at knuckle cracking and some rad ideas for super suits of the future and you’ve got an action packed episode of Brains On.
