Vignettes: The Geology of Rocky Planets

Four planets in our inner solar system—Mercury, Venus, the Moon and Mars—have rocky surfaces that can teach us a lot about our own planet. During winter term, Visiting Assistant Professor of Earth and Climate Sciences Sean Peters asked students to examine how the fundamental geologic processes acting on those planets’ surfaces have interacted to form the surfaces we see today and to learn about some of the knowledge gaps that should be prioritized for future space missions.
