Ep. 41: Searching for Mars's missing water

More than 50 years of missions to Mars paint a clear picture of a cold, dry, desert planet. And at the same time, photographs, minerals, and other data tell scientists that Mars once had as much water as Earth, or even more. Why are the two planets so different today? In this episode of Stereo Chemistry, we talk to scientists about the latest research on Mars's water and where they think the water went.
