8 – Gullies on Mars (feat. Tanya Harrison)

Increasingly, Mars is appearing to us as a living, breathing world with dynamic features. One such feature that has captivated planetary scientists around the world is the occurrence of Martian Gullies, channels carved into the surface as if by water, in a world where flowing water is not exactly common. We talk with Tanya Harrison, a planetary scientist and geologist from the University of Western Ontario. She tells us all about gullies on Mars, how they might be formed, and what scientists are doing about it to learn more in the search for life on Mars.
