Episode 448: University of Arizona planetary scientist Shane Byrne

Scientists have long known Mars has annual seasons just like Earth. University of Arizona planetary scientist Shane Byrne describes how 20 years of observations by the U-of-A built HiRISE orbiting camera have given researchers new insight into what happens on the surface during the 687 Earth-day Martian year.

Shane Byrne spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.
