Icy Satellite Tectonic, Geodynamic and Mass Wasting Surface Features: Constraints on Interior Processes and Evolution
… geologic processes improves our understanding of planetary geology. Many planet- or satellite-scale processes cannot be reproduced in labs, thus analyzing surface features provides insights to confirm, discount, or improve models. I present the methods used to map and characterize the morphometry …

Pueblos, Planets, and Permian Puzzles: The Perils and Promise of Analogical Evidence in the Historical Sciences
… Drawing on case studies from archaeology, planetary geology, and paleontology, I show that analogies grounded in shared causal or mathematical structure can support robust inferences about the past. In particular, I introduce the notion of analogue experiments: controlled interventions on …

Annals Of A Former World: The Remnants Of Water At Gusev Crater And Eberswalde Crater, Mars
Understanding the past and present distribution, form, and behavior of water on Mars is critical to assessing whether the planet is, or was ever, a habitable world. This thesis examines the evidence for a more water-rich past that is preserved at two key locations on Mars: (1) Gusev crater, the …

Konzeption und Implementierung eines GIS-basierten Kartierungssystems für die geowissenschaftliche Planetenforschung
… ist es, eine GIS-orientierte Prozesskette (Planetary Mapping System (PMS)) zu konzipieren, mit dem Schwerpunkt geologische und geomorphologische Karten planetarer Oberflächen einheitlich durchführen zu können und nachhaltig zugänglich zu machen.

Dry Oxidation of Ferrous and Mixed-valence Smectites and Its Implications for the Oxidative History of Mars
Phyllosilicates are widespread on Noachian to Early Hesperian terrains on Mars and can help constrain the planet’s geologic and environmental history, particularly its aqueous and redox history, which in turn can provide clues about past habitability. A range of ferrous and mixed-valence smectites …

Comparative Lineament and Geomorphic Analysis of Chaotic Terrains and Noctis Labyrinthus, Mars
<p>Noctis Labyrinthus (NL) is an extensional trough network connecting the Tharsis rise and Valles Marineris on Mars. Chaotic terrains are a group of polygonally-fractured surface features commonly associated with subsidence due to rapid fluid loss within the subsurface. Polygonal surface patterns …

Viscoelastic Strain, Viscous Rheology, and Behavior of Experimental Lava Flows
… wide-ranging implications across many fields of geology.</p> <p>The body of research surrounding the dynamics and rheology of basaltic lava flows spans many orders of magnitude in scale of focus. Large-scale studies of natural lava flows rely on remote sensing techniques to collect data and draw …

XMM-Newton Survey of the Brightest Supernova Remnants in the Large Magellanic Cloud
<p>Therefore, a realistic understanding of SN contribution from SNRs populations is needed to model the evolution of a galaxy.</p>

Rapid Orbit Refinement of Potential Near-Earth Objects and Recovery of Nearly Lost Asteroids
<p>The Minor Planet Center alerts researchers about potential discoveries of new Near-Earth Objects (NEOs) on their NEO Confirmation Page (NEOCP). Most of these are indeed previously unstudied objects, which must be studied very promptly while initial predictions of their motions are still …
