    The Evolution of the InSight Landing Site Project The InSight lander settled safely onto the Martian surface in western Elysium Planitia (4.502°N, 135.623°E) in November, 2018, and started collecting information about the surface and interior of Mars shortly thereafter. Read more QCD Discoveries Shed New Light on Northern Lowlands Geological Age Project

    The smooth, flat, relatively crater-free northern lowlands fit the profile of a young geologic surface; However, recent findings of buried basin depressions imply the underlying lowlands crust is not as young as previously thought, but ancient like t

    Shorelines on Mars Project Some features on Mars have been interpreted to be shorelines around former lakes or oceans. We are examining the proposed Martian shoreline features using recent imaging data. Read more Martian TARs Project Transverse Aeolian Ridges (TARs) are wind-produced landforms on Mars that may be either large ripples or small sand dunes. Ripples form in a very different way than dunes, so it is important to determine which these features are. Read more Age and Characteristics of Martian Valley Networks Project Valley networks are frequently cited as the best evidence that liquid water once existed on Mars. Currently, we are examining valley networks in other areas of Mars with the goal of understanding potential global and regional climatic differences. Read more Mauna Loa (1907 Lava Flow) Project

    Mauna Loa is the largest active volcano on Earth. New studies have provided insights into the emplacement processes for recent lava flows.

    Young Fault Scarps on the Moon Project The distribution and character of lobate scarps on the Moon indicate that the most likely reason for their formation is global contraction of the Moon caused by interior cooling. Read more Selima Sand Sheet Dynamics and Landscape Evolution (Egypt) Project

    The southern region of Egypt where the Selima Sand Sheet is located was wetter and inhabited in the past. Now it is an uninviting monotonous, dry, vegetation-free expanse. We are examining this evolution.

    Terrestrial Field Studies in the Simpson Desert, Australia Project

    Linear dunes are the most common dune forms on Earth, and they appear on all terrestrial planets that have an atmosphere, yet scientists still do not have a clear understanding as to how they form.

    Light-toned layered deposits in Crater Terby and the Greater Hellas Region, Mars Project

    The physical and chemical nature of the light-toned layered deposits in Terby crater are consistent with deposition of material in a large, standing body of water much earlier in Mars' history.
