The nature of the early martian climate remains unsolved. Geologic evidence, including valley networks, paleolakes, and groundwater release, suggest that the long-lived (Noachian-spanning) early climate …
Diverse hydrous minerals have been identified on Mars and suggest a rich history of water-rock interactions in a variety of aqueous environments. Fe/Mg clays and …
A wealth of missions to Mars have shown sedimentary rocks are widespread and diverse across its surface. Traditional approaches to interpreting the terrestrial sedimentary rock …
The nature of the early Mars climate is currently debated. Geologic evidence from valley networks and crater basin paleolakes suggests that early Mars (the Noachian …
The nature of the early martian climate, hydrological cycle, and their relationship to the impact cratering process has remained enigmatic, but are critically important in …
The next few decades are expected to host a reinvigoration of planetary exploration by humans. The most likely targets for near-term human exploration include the …
Why are the planets of our Solar System so different, geologically? Volcanic, tectonic, and magnetic processes are responsible for many important features of the Earth, …
The state of the climate during the Late Noachian/Early Hesperian has been a longstanding question in Mars research. The abundant fluvial features and alteration minerals …
Exposure, weathering, transport, deposition, and diagenesis have profound effects on sediment on planetary surfaces and the final, observable geologic record. This thesis constrains the ways …
Impact cratering is one of the most fundamental geologic processes in the Solar System. Mars is an excellent natural laboratory for exploring cratering processes, as …
Water-rock reactions affect the evolution of planetary crusts and largely control their potential for habitability and biosignature preservation. Here we use data from remote sensing …
