The life of a NASA astronaut

This episode of Brains On! answers questions about space, including how astronauts breathe, eat, and train in space. Molly and Vincent discuss the history of space travel, how astronauts deal with the lack of air, and the evolution of space food from tubes of paste to more palatable options. They play a trivia game about space food and feature an "Ask an Astronaut" segment with Kayla Barron, a NASA astronaut, who answers questions about the International Space Station, astronaut training, the dangers of sunburn in space, and what happens when astronauts get sick or pass gas in space. The episode wraps up with a mystery sound and acknowledgments of listeners who contributed to the show.
