Though scientists have combined radar and optical observations to generate a 3D shape model of Psyche, which suggests that there is significant variation in the metal content and color of the asteroid over the surface, no one has seen the Psyche asteroid yet, so we will not know what it actually looks like until the spacecraft arrives in early 2026. In preparation for arrival at Psyche, scientists on the mission are thinking about geologic mapping of the asteroid’s surface. This capstone project aims to contribute to that work, helping inform discussions among Psyche team members as they prepare for working with real Psyche surface data in the late 2020s. It will also serve as an exciting way to educate the public about the value of geologic maps and how we come to understand the histories of planetary bodies we will never get to see in person.
