Gravity Assist: There’s Life Under Ice in Antarctica. How About Mars?is McKay Mix 3

From diving in Antarctica’s ice-covered lakes to exploring Mexico’s Cave of the Crystals, NASA astrobiologist Chris McKay has been searching for life in a wide variety of extreme environments on Earth. He’s also working on an idea to send a probe called Icebreaker to the polar caps of Mars. Beyond merely finding life on another planet, he’s excited about the idea that potential life on a place like Titan, with a totally different chemistry than ours, could have arisen independently from life on Earth. Learn about Chris’s exciting fieldwork and the concept of life’s “second genesis” in this episode.
