26. Mars: the core of Mars, water on Mars, NASA missions and Roman mythology

The fourth planet from the sun, Mars is the closest approximation to Earth that we have. In this episode, we discuss how liquid water has been discovered on Mars for the first time by the NASA InSight Lander. We also cover the geology of Mars, including its internal core, mantle and crust. We highlight that similar evidence for water has also been identified on the dwarf planet Ceres using the NASA Dawn spacecraft. For this week's "What in the world?" we use Roman mythology to uncover the origins of the word volcano and a love affair between Mars and Venus.
