Ever wonder what would happen to your body in space without a spacesuit? Given it’s spooky szn, we figured we’d do something a little different for this Halloween episode of AirSpace and dissect one the scariest situations an astronaut could be in. For a crash course in the intersection between astronaut life and rapid decompression we talk to Mary Roach.  And having authored the nonfiction books Packing for Mars, Stiff, and Grunt she’s kind of perfectly qualified to talk about this bizarre venn diagram.

But some peace-of-mind spoilers for our squeamish friends, there’s no threat of exploding or even freezing to death when you’re stuck in space sans suit (despite what literally every tv show has taught us). Don’t let the pressure get to you--just remember to breathe (out).

AirSpace is made possible by the generous support of Olay.
