Hear stories about alien moons, cold stars, and the future of space exploration. Hosted by Dr. Carrie Nugent, it's the only show that gets NASA experts to try unusual drinks.
Dr. Issac Smith visits the show to talk about one of Mars’ past ice ages; a time when most of the planet was covered in ice. He talks about how he made this discovery by looking at the layers of ice deposited on the planet’s North pole.
