Ian Pamerleau, PhD student at Purdue was our guest for this program. We discussed Ian's Nature Astronomy article which is linked to our blog for this program, "Ancient and impure frozen ocean on Ceres implied by its ice-rich crust." We delved into Ceres, the ice on Ceres, its probable origins, the type of ice and the difference with relaxed and unrelaxed craters. We also talked about the suggested muddy ocean on Ceres, the rigid ice rheology, Clathrates and Occator crater.
