Ray and Halo Impact craters on Ganymede: Insights into stratification of icy crust

Kurzfassung

Ganymede, the largest moon in the solar system, presents a compelling subject for studying icy moons due to its unique geological processes compared to its neighbors. As a result, it is now the primary target of ESA's JUICE mission [1, 2]. Predominantly, impact craters dominate its terrains, each exhibiting a distinctive morphology and ejecta pattern. These features help to understand the vertical stratigraphy of Ganymede's crust at a local scale. Additionally, our study investigates the role of spreading and rifting processes in transporting dark terrain material to the subsurface.
