Abstract
NASA's Psyche mission will arrive at the metal‐rich asteroid (16) Psyche in 2029. The mission will test whether (16) Psyche is a remnant of a melted, differentiated planetesimal that formed a molten iron metallic core. Previous studies have suggested that a molten metallic core fluid could erupt volcanically, explaining the high metal content of (16) Psyche's surface. Here we describe an origin story for (16) Psyche using thermal and compositional evolution modeling that outlines when ferrovolcanism could occur. We highlight how Psyche's Magnetometer could detect remanent magnetization associated with mantle intrusions of the core metal.
