On this episode of The Children’s Hour, we travel to Mars with planetary volcanologist Dr. Larry Crumpler. He shares the secrets of the Red Planet — from its rusty surface and giant volcanoes to its two tiny moons and ancient signs of water. We learn how rovers explore, search for life, and even make oxygen, plus what it might take to send humans there. This is a fascinating journey to a world both like and unlike our own.
