How do we know where to look for life on other planets? SETI scientists use analog sites on Earth, not only to study how life has evolved here, but the geological conditions that made it possible. Devon Island in Canada is one such analog. It's been called Mars on Earth.  In this third episode, Gary Niederhoff talks with planetary scientist Pascal Lee, co-founder of The Mars Institute, and principal investigator of the Haughton-Mars Project at NASA Ames Research Center in Mountain View, California. They discuss how a remote arctic island offers clues about how liquid water once flowed on Mars, why the moons of the Red Planet are so mysterious, and Pascal’s discovery of a heretofore unrecognized Martian volcano in 2024.
